Put simply, my machine is running too hot and i can't figure out why...
So I tested some things out last night.
My Build:
******
Microsoft Windows 7 Home Premium 64-bit
G.SKILL Ripjaws Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800)
Intel Core i7-860 Lynnfield 2.8GHz LGA 1156 95W Quad-Core Processor BX80605I7860
ASRock P55 DELUXE3 LGA 1156 Intel P55 SATA 6Gb/s USB 3.0 ATX Intel Motherboard
CORSAIR CMPSU-750TX 750W ATX12V / EPS12V SLI Ready CrossFire Ready 80 PLUS
Antec Nine Hundred Two Black Steel ATX Mid Tower Computer Case
Western Digital Caviar Black WD6401AALS 640GB 7200 RPM SATA 3.0Gb/s 3.5"
1 x HIS H587FN1GD Radeon HD 5870 1GB 256-bit GDDR5 PCI Express 2.1 x16 HDCP
Scythe Mugen 2 Rev b Cooler.

======
Just built this about a week ago, and my system seems to be idling at 45, hits about 70 with full effects on CoMW (Only game I really have right now to test), and when running Prime 95 Small FFT's, will instantly hit 80, and hit 95 after about 30 seconds.
Ambient Temp of my room is around 28.
Bios shows VCore to be 1.24, though I noticed while running Prime95 that it only sat around 1.10
VTT was set at 1.264, but I had reduced this to 1.219
DRAM is at 1.559
I had barely OC'ed, just moving the Bclk to 136 as I don't even want to mess with it with my temps being the way they are. I have changed my RAM profile to Profile1 making it run at 1600 as opposed to 1333.
======
Things I have tried:
Removing side panel - no effect
moving my case above my desk for better airflow, currently it is in an enclosure just barely bigger than the case (dropped about 2 C)
Moved Vcore and VTT down even further - no effect ?
double check heatsink - seemed to be on properly
I then decided to remount and apply AS5, though I may not have completely cleaned it from the cpu before applying just a pea sized drop this time and letting the heatsink flatten it out. After restarting my idle temp is sitting at about 51 now and loads are 5-6 degress higher as well....
I then tried to install the cpu fan differently, and now it idles at like 65. I think putting even minor pressure on the mugen 2 made it lose slight contact with the cpu? It is mounted on there pretty damn good but idk what is going on here...
//////////////
To monitor temps, I am using real temp, core temp, and the ASUS OC software that came with my mobo. The ASUS OC software shows my cpu temp to idle at about 45, and only hit a max of 75 when running Prime 95 small fft's (and the mobo at about 45) and it takes time to build up that high, while the other 2 applications shows it to immediately jump to 90+ instantly.
Lastly, I ran the sensor test that real temp provides, and I'm not sure how relevant this is but at the following loads, the temp was x distance to TJMax
5% 42
15% 17
27% 7
40% 0.9
//////////////////
Could realtemp and coretemp just be providing wrong readings? I have tried to provide as much info as I could the first time around, but any questions/comments/answers would be greatly appreciated! Thanks!!!!
The last thing I can think I want to try, is it just mount the stock cooler when I get home and see if that changes anything. If that works better, perhaps I will buy a more secure/lighter cooler or something.. i dont know
