    Default Anyone Else with a VERY HOT 960GM/U3S3 FX Northbridge Heatsink?

    EDIT] I had originally asked for feedback from owners or on hand users of this board but is now open to all useful comments. I had erroneously thought that there might be more owners of this board, but it is apparent not too many have them or like parsec said, even know/worry that their NB is hot.

    Like I've mentioned on the forum, I cannot stop gushing about this feature packed and VERY up-to-date micro-ATX motherboard. For $55 usd I realize that it was made for:

    -mid level users (some gaming on the side?)
    -Budget level users, either looking for the cheapest alternative (NOT cheapskates) or just plain poor like me.
    -Looking to squeeze the most from their AMD components with the privilege of using modern tech like USB 3.0, SATA III 6gbps and DDR3. Maybe the only thing missing would be a PCIE 3.0 video slot (hint).
    -Smaller format users that think that ATX and worse, Extended ATX boards are too anti-ecological (or folks with more nimble hands and fingers).
    -Have heard of Asrock but haven't given them a shot and decided to do so buying this item. Asrock is the 3rd supplier of motherboards world-wide just after Asus and Gigabyte (have several of these too) after all. There is buzz about the brand for some great things.
    -Non-overclockers. Quite visibly not sturdy enough for real overclocks (what did you expect for $55 usd anyways?)
    -Don't mind using a chipset (760g/SB710) that came out in 2008.
    -Know what 3 + 1 phases in VRM and no heatsinks over the Mosfets really means.
    and so on.

    Getting back on track, everything works as advertised altho maybe not with record breaking benchmarks, but very very acceptable, EXCEPT FOR:


    -------A VERY HOT TO TOUCH NORTHBRIDGE HEATSINK------

    This is definitely the hottest NB heatsink of the over a dozen motherboards of all brands that I have had. If you check my profile, I use a very tame Phenom II X6 1035t processor with a 95 degree TDP, not one of the FX 8XXX eight core procs with much higher TDPs. Besides I use an external video card so I have the IGP turned off which resides in the NB.

    My horse (common) sense dictates that this would be the first part to fail on the motherboard (mosfets are curiously cool in spite of the sparse phases), willing to bet that it might not even last the warranty period or barely reach it.

    Everyone knows that heat is the worse enemy of any system/component. Tech shops report that the component that fails the most are motherboards. When a mobo fails and is a couple years old, it usually means that its time to send the whole system to the bin and buy updated hardware or a new system.

    To prevent this from happening on mine (probably voiding my warranty), I modded the northbridge with a bigger complete heatsink (the factory HS is in the shape of an "L" in order to make room for a PCIE add-on card-I don't need any) and screwed a 40mm led fan spinning now at 5,000 rpm (mobo does not regulate the 3 pin PWN header). The new heatsink is still pretty hot but much less than before. I guestimate that it went from 90c to around 70c. I will upload a worklog of this mod if enough people ask for it.

    In conclusion, I'm trying to find out if I just have bad luck or it is something common-place with this mobo. Oh, for those that might not know what or where the northbridge heatsink is:

    I would really appreciate your feedback.

    Thnx!

    P.D. As the NB does not have a sensor (or one that is visible), I am only asking for users to take off the cover of your case, reach in and touch the SIDE (not the tops of the fins-too small) of the heatsink. It would be great while running at idle or if not, with the system off but immediately after shutdown. You could use the terms:

    --warm - not a problem to touch for over 5 sec.

    --hot - you can notice it and feels somewhat uncomfortable to touch but can hold it 5 sec.

    --very hot - very uncomfortable or cannot keep finger on more that 5 seconds.

    If you are leery of sticking your hand in your system, an infrared temperature gun reading would be more than fine.

    Thnx again!

    Well, while folks get around to checking this thread, a storage expert/guru on this forum that goes by the nic of parsec, recommended that I check out a free hardware monitor app called HWiNFO64 inorder to check if there was a readable sensor for the northbridge on this mobo. Upon downloading and installing this new (well to me) software I set the sensors "on" and got the screen below.




    <a href="http://s711.photobucket.com/user/papangcun/media/ASR%20960GM%20U3S3%20FX%20NB%20Cooling/LowerVtoNB_zps6d87646b.jpg.html" target="_blank"><img src="http://i711.photobucket.com/albums/ww119/papangcun/ASR%20960GM%20U3S3%20FX%20NB%20Cooling/LowerVtoNB_zps6d87646b.jpg" border="0" alt=" photo LowerVtoNB_zps6d87646b.jpg"/></a>

    The only line that seemed plausible to be the NB sensor was the one termed "Auxiliary". To the far right is Aida64 which is my mainstay app for monitoring just about everything happening in my system via an OSD panel. You will see that Aida does not detect a temp for the NB so I came to the conclusion that this board did not have one, although it did give me a voltage reading, hmmmm.

    Do you remember that you received an app called "ASRock OC Tuner" on a cd that came with the board? I installed it just to see what it was about but left it aside when I came to the conclusion that this mobo was not overclockable precisely because of the hot NB heatsink. What I had forgotten is that you can not only push things up like voltages, multipliers, frequencies, etc., but you can also push them down.

    On "CPU NB Voltage", the default is 1.150 v so I started to do an "undervolting" test routine. It is the same as OCing: change a number, run a stress test to see if the OS is stable (I use HeavyLoad Free) for 5 min., push the number to the next level, test and so on until you get a BSOD or a corruption of some type like screen distortions/corruptions. I managed to get it down to .975 v but was rewarded with a BSOD after a minute of testing so I settled on a voltage one step above what you see in the pic: .9875 v., around a 16% reduction from default.

    On "mGPU Voltage" it would only go down to 1.10 v so I left it at that (pic shows default voltage 1.15).

    The "Auxiliary" reading in HWiNFO64 fluctuates a lot and the stickler is that it will only give a constant reading when on load. When in idle, it will only update every 2-3 min. which is a pain waiting for a new value to show up. However, the min. temp value is way down to 55.5 c when at default it would hoover over 80 c.

    In the bios, I see no way to lower the NB voltage to .9875 v. so the downside is that I have to have OC Tuner running or it will default back to 1.150 v. rebooting.

    Sooo, if you are not the adventurous, intrepid and curious type (kidding, everyone has a right to be like they are) and are not up to doing a mod to your NB heatsink, this work- around will help lower the temps. I STILL feel the heatsink hot but it might be just enough to get you over the warranty and a bit more. Like I mentioned, I use an external video card so for you that use the IGP (lodged in the NB), underclocking might most probably cause you a world of pain, however give it a shot even if not to the levels I went. Just remember "It's cool to have cool components"!

    Good luck and good UVs (undervolts vs. OVs which are tied to OCs which everybody here understands)

    Hmm, that Auxiliary temp reading might be the NB chip. Programs like HWiNFO64 cannot know what every sensor value is for, unless the mother board manufacture will share that information. They apparently do not always do that. So the programs use generic names like Auxiliary, SYSTIN1, etc.

    You say that the Auxiliary temp reading changes a lot? It also won't update, and apparently gives you a value of 0.0 at times? That is strange, I've never seen that before. The "NB" type chipsets on Intel boards tend to stay at one temperature most of the time, and fluctuate very little. That is, unless it is being actively cooled, and you can control the cooling fan, and also change the chip's voltage.

    So it seems that Auxiliary temp reading changed when you changed the voltage? That is a good sign that it actually is the NB temp, as you know.

    I could not find much information about the 960GM (760G) chipset, but I did find this excerpt in one overview you might find interesting:

    The integrated graphics northbridges were also benefited, as most of the IGP northbridges were made on 55 nm process manufactured by TSMC with the inclusion of ATI PowerPlay technology, allowing dynamically changing the core clock frequency to minimum 150 MHz.[13] The 780G Northbridge, sporting DirectX 10 support, consumes only 11.4 W on full load, 0.94 watt when idle

    That might explain the changing temperatures, but if the graphics is not being used, why doesn't it stay at a lower temp. Actually, considering the graphics are on that chip, and we know how hot video cards can get, no wonder it gets very warm.

    I know you are not using the integrated graphics, so unless you need a driver, etc, for the ATI PowerPlay technology, it should be active. I see there is the AMD OverDrive ver:4.0.5 as well as OC Tuner ver:2.4.71. Any chance you can do something with the chipset with OverDrive?

    I believe you use a 40mm fan on the chipset heatsink? Frankly, IMO a 40mm fan is not much of an air-mover (flea-fart), I'd suggest using a 60MM fan and get creative about mounting it. I've used coarse threaded wood or sheet metal screws, simply because they fit between the heatsink fins/fingers, and are larger in diameter and fit in the fan screw holes better.

    Hola Amigo parsec!

    Always glad to get a comment from you, never a one-liner or anything copied and pasted, hehe.

    Well, firstly before I forget, I checked the profiles I could save in the bios that you had suggested previously, and verified that they are voltage profiles in the "Overclocking" tab. So managing a boot profile is a no-go. Worst, there is no way to set the NB voltage other than upward (which was not my intent in order to cool the NB) so it was too a bust as I said above. This must be because the mobo is a budget (to not say dirt cheap) level item so the bios is also "budget level" (err, dumbed-down??,...simpler). Anyone trying to OC the IGP should be hauled away in a straight-jacket (insane)!

    Back on topic, HWiNFO64 is surprisingly deep and thorough, moreso than Aida64. It was what jump-started me to think of another way to control the NB voltage being "OC Tuner" the answer. The Auxiliary temps do fluctuate which is not normal for a monitor but I chalked that up to the non-constant readings that it does as shown in the "Current" column which will, in idle, show zero but suddenly flash a value which is then incorporated into the data of the rest of the columns on that line, specially the "Average". Even on load, the reading is not constant but much more active, a split-second separating every reading.

    That was the only thing, other than touching the NB which is not that trustworthy, that gave me any inkling of what was or could be happening as I underclocked the voltage more and more. Atleast it was more or less consitent altho it would give an occasional wonky reading like 12c, which is not credible, and would mess up the Average column calculation. I would have to reset the values to correct this until another weird reading would knock it out of logic. Readings were more consistent when in idle except for the spaced out readings.

    You said:

    The integrated graphics northbridges were also benefited, as most of the IGP northbridges were made on 55 nm process manufactured by TSMC with the inclusion of ATI PowerPlay technology, allowing dynamically changing the core clock frequency to minimum 150 MHz.[13] The 780G Northbridge, sporting DirectX 10 support, consumes only 11.4 W on full load, 0.94 watt when idle

    Where do you get this info? You must be a lot better than me googling ;)

    Altho I have had the internal graphic on "Disabled" in the bios from the beginning, could it still be working/active? If disabling the IGP means setting it to "Idle", that would explain why the NB HS is so hot. Hadn't seen it from that point of view. I hadn't installed AMD Overdrive because I know it is for overclocking video and on this mobo, is close to committing suicide or atleast shooting yourself in the foot. I will give it a shot to see what I can do with the IGP altho obviously it will see first my AMD HD6850 external vid card. It seems that you not only know a lot about storage but also video, hehe.

    About the relatively tiny 40 mm fan, besides having leds (important to modders like me) it fit exactly the heat sink I modded in place of the original heatsink. The original HS is too 40 X 40mm but has a third or more of the fins chopped off to tiny stubs inorder to permit an add-on PCIe to be used in the slot right behind the HS. You can better see this below:

    Anyone Else with a VERY HOT 960GM/U3S3 FX Northbridge Heatsink?-960gmu3s3-fx-jpg


    Like I told someone, a pic is worth a thousand words, don't you think? No more guessing or tip-toing through badly written/explained text. People want help and they don't even fill out their PC specs so we have to tear it out of them bit by bit. And they get frustrated when an answer can't be offered off the bat! I would have shot myself a while ago if I were an Asrock tech who was forced to answer all these half-baked inquieres....like Sean or maybe even Emily???

    So I got a another HS from a junk mobo that was also 40 X 40 but complete, otherwise I could not screw in even the tiny 40 mm fan. I definitely could not with the original HS. Just like you said (obviously a modder too) wood screws were used to hold it in place fitting tightly between the fins. I have larger HS but in this tiny m-ATX board (even smaller than the mATX standard), will not fit inorder to use a larger fan (I have a spare 60mm PWM fan-not leds tho). You get spoiled with fancy expensive big boards like yours. You do know they are anti-ecological, no? Just kidding.

    I will get back to you on this and....thnx for the advice....again!

    Saludos

    P.D. Another thing I noted is that the more drives I connect to the board, the hotter the SB heatsink gets, especially with IDE stuff which was not very energy efficient. And the darn IDE HDD was at 50c when my others were at 35c, so I unplugged the molex until I have to use it. Fortunately only once in a while. OH well......

    Your board's profiles sound weird to me, the BIOS profiles I've used on every board I've owned save ALL the BIOS values, every last one including boot order. First time I've heard of a partial-setting saving BIOS profile.

    That statement about the AMD 700 series chipsets was from... Wikipedia. Just one of the random hits I got while searching, and since AMD does NOT provide any data sheets on their chipsets, we'll take whatever bits of info we get.

    In case you didn't notice, HWiNFO64 allows you to set the "Scan Interval" or the time between sensor reads, which is two seconds by default. Is the Auxiliary temp reading the only one that acts strange, as you described? Increasing the time between sensor reads might help that value become more normal, but who knows.

    You lost me on this statement:

    Altho I have had the internal graphic on "Disabled" in the bios from the beginning, could it still be working/active? If disabling the IGP means setting it to "Idle", that would explain why the NB HS is so hot.

    Are you saying that disabling it would also disable the power saving feature? I kinda see the reasoning for that conclusion, but how could AMD be that... stupid to allow that?

    You're using that 40mm fan because it has LEDs on it? Come on, performance before bling! Frankly, I consider any fan smaller than 120mm to be a toy, and barely worth using. Sure, you must use a small fan on a chipset heatsink, and I have a box of small fans that I collected trying to find good ones. Some of the small fans from the stock AMD CPU heatsinks are decent fans, but at least 70mm I believe. IMO, 40mm X 10mm fans are worthless except to make noise. Get a bigger fan, 60mm x 10mm or 15mm are pretty common, I've got more than I'll ever use since I reject most due to being to noisy. I finally used a manual fan controller on a decent 60mm fan for my X58 chipset. My newest Z87 board's single chipset (Z87, duh!) runs at ~35C, so not a problem at all.

    My "fancy, expensive" boards, in the $150 - $200 range are not that fancy, when $300 - $400 boards exist. BTW, I know you consider ATX boards as "anti-ecological", I read that in another post of yours. That's Ok, I'm not using a video card in this PC, so add your video card's area to your mobo, and we're almost equal.

    Hmm, more drives on the SB/SATA chipset warm it up. More load, more power needed, makes some sense. I don't see that much with Intel SATA chipsets

    Hi Papang,I also own the same board, I am glad you noticed the issue with it and looking into correcting the problem. When I first got this board I installed a set of smaller north and south bridge fans 40mm sizes. After reading your info I check it with my infrared thermometer, the kind that checks temps on little nitro cars for breaking in motors exc.. Anyway at the hottest spot on it, is at the bottom of the heatsink top of the northbridge chip, it gets up to 101F-102F degrees. Can only imagine how hot it gets without the fan installed. I would like to get it down even more, so Im going to try and put a AMD 80mm cpu fan there. Please let me know any and all information you have that can help my situation out, and if there are any sure ways to lower the temp by lower volt settings, or anything you can think of exc. exc.. Anyway in answer to your question the Northbridge does indeed get up in the lower hundreds at the hottest part with a 40mm fan. The rest of the heatsink is all between 90-99 degrees, checked by wireless infrared thermal temp reader.. Please let me know what your thoughts are..ThanksSolderIron4

    Are you sure that heatsink temperature is only ~100 Fahrenheit? That's only ~38C, which would not be bad for that chipset. Yes, the heatsink won't be as hot as the chip, but in another thread Papang said he could barely keep his finger on the heatsink for very long, a few seconds at most.

    If your heatsink is really that temperature, then Papang's has a problem with his, or you know of a secret setting that will reduce the temperature? Are you using the onboard video, or a separate video card?

    Hi Parsec,
    Thanks for your response, I have updated the bios from P1.20 to P1.30 which I believe to be the latest version, but there are no changes to the temps. Also I rigged up a second fan onto the NB chip. So there now is a 40mm and an 80mm fan directly on top and over the smaller one, all most encased in side of the 80mm.. This now lowered the temp down to 95 degrees, at the base of HS and top of the NB chip. This was checked vita thermal infra red temp reader, know to calibrated and operating as it should. Yes, I am using the onboard video as well, I would like to get a V card someday if it helps make it run cooler as well as make it perform better.. Parsec, what do you think of me over clocking? Or is it too risky for this type of board. My processor is a 6 Core AMD FX-6300 Vishera 3.5GHz (4.1GHz Turbo) 16GB Ram. I appreciate all thoughts and suggestions. Oh I forgot to mention, I am testing this out of a PC case and on a work bench presently, my case is in the mail and should be shipped here by Thursday. The link below is the case if you want to check it out. It basically has plenty of power and plenty of fans Twin 120mm Jamicon high air flow @ 80.11 CFM each Plus some others, and some temperature probes with a controller thing..

    Please let me know what your ideas are..
    Thanks very much!
    Sincerely
    SolderIron4

    Default Re: Anyone Else with a VERY HOT 960GM/U3S3 FX Northbridge Heatsink?

    Wow on those NB temps, Papang will be wondering what is going on with his. He uses a separate video card, and was wondering if that was somehow not allowing the video portion of the NB chip to not throttle down. Your 40mm fan must be better than his, or something else is going on.

    Regarding an OC on your board, first understand I am not at all an AMD expert. Your board's specs say it supports 8 core AM3+ CPUs. The only entry I see in the CPU support list for a 6300 CPU is: FD6300WMW6KHK, a 95W TDP CPU that seems to match your CPU's specs.

    The main potential issue I see is the limited number of VRM chips on the board, and they do not have heat sinks.
