    Default 3570K Runs "Hot"

    I have a 3570K running at the Optimized Default settings and I'm reasonably happy except...compared to the 2600K it runs very hot. I have tried the Corsair H60 (push/pull), the Corsair H100 and the Thermaltake Water2.0 Pro (push/pull) and it makes no difference which cooler or which fan(s) I use the system jumps to 55C after a minute or two of Prime95 and reaches ~58-62 depending which fans I'm using when Prime95 does it 8K routine or after 31 minutes. By comparison, the 2600K will run Prime95 at 4.5GHz (1.28V) forever and never get above 56C using an H60 cooler with two Blade Master PWM fans (push/pull). One of the vendors sent me a few links on why the 3750K runs so hot:

    Intel caught out using cheap thermal paste in Ivy Bridge? -- Engadget
    Intel's Ivy Bridge Hotter Than Sandy Bridge When Overclocked

    To add insult to injury I called Intel Technical Support to see what they would say and the answer I got was "The 3570K is not supported for OC'ing therefore don't worry about the temperatures it will slow itself down when it gets to 67.5C!" Un-XXXXing-believable response. Anybody with one of these things (3570K) have any ideas and what can be done - I'd trade even for a 2500K - just joking it is a nice setup but it sure don't want to OC very much. I thought maybe if enough people were complaining Intel might spend an extra dollar or two and go back to what worked for Sandy Bridge? But I'm sure that is a gross over simplification.

    all ib chips run hotter than sb,they are roughly the same temp wise as the i7 920/930/950 cpu's,but they do perform better than sb clock for clock 4.5ghz on ib works out to a 4.8ghz oc on a sb cpu

    personally i think its down to all the extra transistors theve squeezed in and trigate transistors,the heatsink can only shift so much heat then its overcome,im on the fence about the thermal paste

    Yeah, yeah, I knew all that before I bought one. That's why I bought the 3570K since I thought it would run cooler than the 3770K (4 threads versus 8). I never in my wildest dream realized I'd have to pack the thing in dry ice if I wanted to run it much beyond stock settings.

    i think im gonna wait till haswell comes around,see how hot or cool those run,sb is just right temp wise but ib is gonna be a struggle to cool if you dont have custom water

    It is well documented how much hotter the IB chips are when compared to the SB ones. You even knew before you bought so you can't really complain as you were aware of the issue.
    My 3570 runs fine after I flipped the lid and using a very cheap cooler. It is overclocked to 4.4Ghz with no issues.
    I did the research and knew what I was buying and it met my expectations.

    VimesUK,
    Good for you. I'm happy your happy. What kind of temperatures does you system show when under 100% load with your "cheap cooler" meaning Prime95 for an extended period?

    Remember that I had to "flip the lid" on my 3570k - I removed the IHS. I then applied a layer of liquid metal TIM to the core and replaced the IHS. Another very thin layer of liquid metal and then the cheap Arctic Freezer rev 2 cooler applied. The cooler cost me 12.99 delivered from Amazon.

    When I run Prime95 (small FFT's) with my 3570k clocked to 4.4Ghz ( a 0.06v offset) my cores will get up to 75c to 78c max in a warm living room.

    Prior to removing the IHS I was getting over 90c. This made a big difference for me.

    However I know the TJ Max is 105c and so I would doubt in real life use I would have got close to that max as it seems only benchmarks or video rendering will stress my PC for long continuous lengths of time.

    I'm not sure it is too fair comparing the 22nm IB with the tri-gate transistors etc etc to the same cooling achieved with the SB. It did not help the cooling with Intel using the TIM they did, but that, for me, was easily resolved.

    Intel...

    Surprisingly, Intel has admitted that their latest Ivy Bridge platform runs hotter and its because of the increased thermal density which is the result of 22nm manufacturing node. Intel said, “users may observe higher operating temperatures when overclocking”. They further added, “This is as designed and meets quality and reliability expectations for parts operating under specified conditions.”

    This means that even though Ivy Bridge runs hotter but one shouldn’t be worried about it because its designed this way and it meets all the quality and reliability expectations.

    ...I can only imagine that when they shrink again to 14nm heat might become a bigger issue for those pushing the limits of an overclock.

    how did you part the cpu heatsink/backing plate from the chip vimes? seems a daunting task

    I finally got up the nerve to see what the 3750K would do with 1.26V, LLC set to Turbo and the Multiplier set to 44. I ran Prime95 through the 8k test (~32 minutes) and the cpu reached core temps of 67, 67, 70, 70C (Core Temp). The room temp was ~20C. Too hot for me based on 2600K experience but OK by Ivy Bridge standards? I probably could shave a few degrees off the max temps if I used the fans that came with the Thermaltake Water2.0 Pro but I have it set up with two Cougar PWM fans that are very quiet but max out at 1500 RPM. Although the fans never got past 1400 RPM using the Gigabyte MB CPU Fan connector with the BIOS set to Manual and the Slope set at 2.5.

    70c is fine for 4.4ghz on ib,80-90c seems to be the norm from what ive seen on air,80c was the norm for 4.2ghz on x58,and roughly 72-75c for 4.5ghz on sb/2600k with air
