Maximum CPU Efficiency... - Page 2

post #11 of 17
Thread Starter 
I used to run Intel Burn Test on max to test stability, but I have never found an application that stresses a CPU as much as that program. I don't find that representative of commonly used applications. Prime95 stressed my CPU much more than WCG ever does. My CPU load temps with WCG range from 50-56C and Prime 95 usually averages around 60C across all cores.

PS: Down to 207 Watts. I'm going to put my GTX 570 in now that I trust the H80 won't leak all over everything. That should put me under 200W. I just put in the 2 Scythe UKs in Push/Pull with shrouds. They are running at ~2200 RPMs and are MUCH better than the stock Corsair fans. The stock fans seemed to whine and are very loud compared to the UKs.

At ~2200 RPMs, the audible noise is just the large amount of air moving, not the actual fan motor. You hear the motor on the Corsair fans. The max speed of those is ~2400 RPMs and are noticeably louder than the Scythe UKs at ~3000 RPMs. Temps also dropped a few degrees! I'm still amazed at the temps this H80 gives compared to my Xigmatek HDT-S1283 even with push/pull UKs.

I'll post a pic later to show how much space it takes up with the dual fans plus shrouds.

Ok. I installed the GTX 570 and still only at 207-211W. I'm going to reinstall drivers to see if that makes a difference from switching video cards.

Here is a picture of the H80 with 2 Scythe UKs and 2 25mm shrouds.

I'm rockin' pretty much the same cooler, sans the shrouds. You may wish to consider a quality fan controller on the scythe UK's, they get annoying running full blast constantly. Warmest my cpu's been in the last week is 46c, running boinc the whole time. Been averaging around 36-40c. Good setup.

I do have a fan controller with an LED readout and several temp sensors. They are 3K RPM fans and run them at ~2200 RPMs. My temps are only low to mid 50s. I like my room to be warm, and those temps are still very good.

They are very low for an i7. The cpu coolers that Corsair sells are kickbutt. I wish the UK3K's were a bit quieter at times, but that's the price you pay for moving massive amounts of heat and air.

This kind of approach to overclocking is so much more impressive to me versus how it's conventionally done around here; outstanding!

I think are still pretty quiet at ~2200 RPMs. The main noise seems to be the large amount of air being moved. I've heard lots of trash talking regarding the H80, but it's not slouch.

Thanks! I agree. It's easier to set the voltage high and raise of the BCLK and forget about efficiency. It'll save a little each month, but the heat output into my apartment also important to me, as well.
