    Hello again all!

    The 1.2m 3 pin fan cable turned up yesterday and ive now been able to attach the fan on the outside of the case, it isnt pretty but it seems to be working (will need to put some tightes around it to filter out some of the stuff its likely to pick up in this room). Today the CPU is at 33c and the SYS is at 38c so im pretty happy.
    Im going to give it a good go on Prime95 later, though not for 9 hours again. Once im happy with it i shall start to neaten up all the cables, as it looks like it was put together by a blind spider that was in a hurry at the moment and i think that should help with air flow. I also think im going to find a 5.25" drive bay fan mount and put that just above the current front fan.
    Also does anyone else out there have this CPU / motherboard combo in an air cooled case? As ive yet to find out what temps i should be aiming for.

    So far so good!

    I think i *might* have found a solution for this rather hot CPU:
    Delta 120mm Focussed Flow Fan (EHE)
    Strap one of these to it! I think it will work and help keep it cool, but if my memory of Delta fans is correct, then im not sure if this is totally safe to use on CPU heat sinks due to the vibration caused by the fan (4000RPM). I could be wrong and this is not an issue but im going to look into this abit more first. Also the thing is incredibly loud at 59dBA but i guess thats a price im willing to pay for piece of mind that my CPU will stay cool even under massive load. I also think i need to up the voltage again, as this system now crashes under Prime95 after about 15 mins.

    Peace of mind is priceless. An easier way might be to convince yourself that 70-75C under load is okay and normal for i7 operation though lol. These things start thermal throttling closer to 95-100C.

    Good advice so far.

    Just a couple of notes. Your CPU is probably set to 190*20 = 3.8GHz, with turbo on. When turbo kicks in, the multi will rise to 21, giving you 4GHz.

    May I ask, did you get the bundle from Overclockers UK? If so, they're great bundles. My cousin bought the same bundle. They create a BIOS profile of the OC and also give you a printed sheet with it on two. Excellent attention to detail.

    From what I can gather you seem to be reading temps from EasyTune, which only reports from the CPU socket sensor. Download a copy of RealTemp instead. That will give you a readout for each physical core from the DTS sensors insite the CPU itself.

    You may find that the Delta fan will be overkill. After a certain point, many heatsinks simply stop scaling with airflow, as the limiting factor at high air volumes is thermal conductivity of the material, not air flow. Personally I can't recommend the Noctua fan in my sig enough. It pushes out 54CFM at 19dB. Does the Fenrir support the fitting of a second fan for a push/pull configuration? If it does that will both help focus flow through the fins and have a synergistic effect on static air pressure limitations of the fans.

    If you do go for the Delta, make sure you have a sturdy fan controler, as they do draw much more current than a standard fan, and fit a fan guard too..... don't want to loose a finger!!

    Spoken like an engineer! However, I believe the first limiting factor would be the heat transfer coefficient between air and metal, the thermal conductivity of the material would start to become limiting only if the air-metal heat transfer was very fast (and I don't think it is). Lots of fluid dynamics coming into play eh.

    Anyway, it is very true that it will likely not be worth that crazy loud fan. After having a good heatsink and decent fan, what you can try to improve is the temperature of the air the fan pulls in by having a decent case fan grabbing external air. I am actually considering a monster 200mm or 360mm fan to attach to the side of my case. They can push over 100CFM at <21db. Just need 1 of these and my case air should be just about the same temperature as ambient. They go for about $25 at FrozenCPU.

    Indeed my meaning was conductive heat transfer from the heatsink fin material to the air, not actual thermal conductivity of the substance itself (I believe the Fenrir as most HSF's is nickel plated copper base, copper heat-pipes and aluminium fins). Thanks for clarifying.

    A full copper sink for example a TrUE Copper would likely scale very well with a high CFM fan. For most regular sinks, the Delta would drop temps (Delta droping delta ), but wouldn't be worth it, and will give you a headache, both literally and figuratively as you search for a fan controller rated for 3 Amp (36W) fans. The only one I would trust for the job is the Sunbeam Rheobus Extreme, and even that is only just within tollerance for that fan. techPowerUp :: Sunbeam Rheobus Extreme Fan Controller Review :: Page 1 / 6

    A large side intake would be great, but if the OP definately can't use one due to clearance issues, I recommend a Scythe Kama Bay: Scythe KAMA-BAY 120mm Fan for 5.25" System Cooling

    One of these and maybe some home-made ducting of some sort will give a nice supply of fresh air to the CPU fan. Many cheaper cases I've used in the past have a similar ducting and air vent on the side of the case, meaning if you use a down-draft HSF, you get external air.

    Right on.

    Actually an X-bit article shows it performs almost exactly the same as the non copper version (LINK). In fact, this backs up what we were just talking about perfectly! The conductivity of the material itself is not limiting, its the conductive heat transfer to air. That's why an already well designed heatsink (like the TRUE 120) will perform similarly if its pure aluminum or pure copper! The copper-to-air and aluminum-to-air heat transfer is almost the same!

    Now if you have a poorly designed heatsink and your not getting your heat spread out into the fins, copper might help.

    Woah those KAMA-BAY things are great! I happen to have 3 5.25" bays free also, so I can use it in INTAKE mode. Thanks for pointing these out

    I will try and dig up the two articles where they tested the TrUE Black vs the TrUE Copper with the same Delta fan the OP mentioned. The one I remember the most vividly showed a 4c temp decrease at 190CFM compared to 75CFM on the TrUE Black (aluminium fins) and a 10c drop with the same fans compared on the Copper version. It may well be that the reason for the decrease was that the aluminium was saturated while the copper version was not. My Physics skills aren't up to assertaining the true reason for the copper sink scaling with the Delta fain more than the aluminium one did, but it did so (in those particular tests anyway) by a not insignificant margin. TIM used was the same in both tests, and I believe the only difference between the sinks is material used, design is of course identical for both versions.

    If you're lucky enough to find a supplier, there is also a Lian Li manufactured bay cooler. It's of slightly better quality and comes in a sweet brushed aluminium finish, which matches Lian Li cases perfectly.

    It always seems to be the case that I can never find an article I need when I want to.

    This article covers briefly the use of a Delta fan on the true copper, but only compares it to a Scythe S-Flex, and doesn't bother trying it on an aluminium TrUE, sadly.
