So I got new i7 860 and though it's under Corsair H70 with 2 Sharkoons Silent Eagles, only after few minutes of foldings tems are reaching 85 degrees, checked and re-checked if I applied thermal grease properly, re-applied again, all to the same effect. Any ideas? Thanks.
Yeah, stock. And I'll tell you what's wrong. It's the bloody fans! I swapped them for the Fractal Design case fans on the radiator and now the temps are in the range of 66 degrees on stock. I guess still a bit high, right? But much, much better now.
What temps do you get with the stock fans that came with the H70. They cool the H70 reasonably well and aren't too noisy if you use the supplied resistor. Cooling radiators is all about the static pressure of the fan which, I'm afraid, most normal case fans don't have in abundance. I didn't have a clue about this until recently when the same thing happened to me and finally found that the Gentle Typhoon 1850 is a good compromise between cooling and noise.
Temps on standard fans was around 67 degrees. I guess next week is couple of Gentle Typhoons and a change of motherboard. This will have to run on stock for a week. I hate running stock... Could you recommend me a great overclocking board for my CPU?
That temp seems way too high at stock speeds. Is that without the resistor? Is the H70 in intake or exhaust configuration? Did you notice whether the existing paste was making even contact before you reapplied it? Is there a good airflow through to H70 from the case intake fans? Can't really be much help with a m/b recommendation as I've never owned a 1156 socket board. Can only say that I've mostly bought Asus and have rarely regretted it when it comes to overclocking. Following a bit-tech review recommendation will probably be the best approach.
I'll read some reviews. It's sad, because the PPD actually dropped, Core i3 @ 4.2 GHz was faster than that. It's in push/pull configuration, taking air from the outside of the case. No resistor on the fans either. I'll try to revert to stock ones later and see how it goes.
I've got an Asus P7P55D-E with an i5-760 in it, it's overclocked @ 4Ghz from 2.8 running smp 24/7, cost me £100. Good board if you don't plan to use dual graphics cards for gaming, doesn't support SLi, supports crossfire but the 2nd slot is only x4. They have other P7P55D-* models that support SLi but they are more expensive. I can recommend also that you don't get the Gigabyte GA-P55M-UD2, this seems to be liked in the CPC mag, they seem to use it a lot for testing but I managed to kill it after about 20mins @ 4ghz, and found other forum threads that indicated that it wasn't a unique problem to me.
That seems like a decent board Jondi, the Asus I mean. Folders don't need a board with SLI or Xfire, just two PCI-E slots. You can also fold easily on a 4x slot
I'll check out this board. For now, just checked, temps stabilised @ 69 degrees 100% load, but stock. That should be all right for few days right? I noticed also this CPU is very sensitive. On i3, whatever I've done PPD stayed the same, here when I'm not doing anything it's about 5500 PPD, when I go here it or watch youtube, it instantly goes down to about 3700 PPD. Weird...
It's finishing off the old project from old cpu, maybe once it's done I'll get some proper project with decent ppd?
Your temps do seem high especially is that's load under folding. You could try changing the vcore from auto to manual as you motherboard will always give you more than what you need.
So this is what I've done: 1. Disassembled everything. 2. Cleaned the TIM and reapplied the new one (this time Arctic Silver 5). 3. Put the fans that came with Corsair H70 and connected them to case's fan controller. 4. Put one fan on the roof and connected to the fan controller. 5. Put 2 case fans at the front. 6. Turned down the controller to minimum rpm's. Turned on folding at stock CPU speed (for now ) Result: 59 degrees under load. Now, I'm asking you - is there anything else I can do apart from replacing the radiator fans to Scythe Gentle Typhoon's?
My I7 875k@3900 temp is 58 degrees when folding. (Silver arrow) I found artic mx-3 to be 3 degrees cooler than artic silver 5 I found running -smp 7 gives more ppd
-smp 7 gives you more PPD? I wonder why it's that? Plus we'll see the temps once I slot the CPU into a proper motherboard and change the fans on the radiator. I must admit, this little board I have is dreadful when overclocking this processor. On the side note: what is the default voltage for i7 860? My bios show different every time I get to it and I have no idea if I'm giving it too much or too little when trying to overclock the CPU.
If all the case fans are intaking air you could try putting the H70 in exhaust configuration. Apologies if I'm misunderstanding but you mention that you connected the stock H70 fans to the case controller then set it to minimum. They need to be allowed to run at 1600 to 2000 rpm to have sufficient static pressure. Also, the 1850rpm Gentle Typhoon will not cool any better than the stock fans (at full speed) but they will make considerably less noise for roughly the same benefit.
