So... maybe I was just a bit too much conservative on my AS5 application , or is it the fact that I might have made air buble in the AS5 while sreading it.
GAH, I had a 2 paragraph post responding here and the site crashed when I hit submit!!!
Artic Silver does NOT recomend you spread it out when applying. They specifically state not to do that because it causes air bubbles as well as possibly causing gaps in the seal between the compound and the heatsink/CPU.
They state to place an amount roughly the size of a BB in the center, then press the heatsink down evenly, twisting slightly side to side. This forces air out and creats a seal.
What I do, and it is a pain and a little wasteful, but I find it more accurate.....is to follow those instructions, but don't tighten down the heatsink. Instead, immediatly pull it back off. Check how the compound spread. Did it get fully pressed out and spread across almost the whole CPU? Then you clean the heatsink and the cpu completely and re-apply, making any changes you deem needed based on the test. If it wasn't fully spread out because the heatsink wasn't seated, you may have to repeat this test until it IS fully spread. If it spread, but didn't cover the majority of the CPU then apply a little more this time. Then tighten it down and turn on the computer, check the temps in the BIOS, if it looks good, let it boot to windows and run some tests.
Also, as was mentioned, AS5 requires 200 hours of heat to cure. What I recommend is to let the computer idle for 24 hours. Let the CPU burn in, get comfortable. Then turn the system off for about 8 hours, let it cool completely down. Then turn it back on and load the CPU....either Prime95 or better yet, with Folding@home. Let it run at max temps (as long as those temps are safe, and watch for heat creep) for about 8 hours, then turn it off and let it cool for 8 hours. Finally, turn it back on and load the CPU again, check for heat creep (this is where it starts at a cetain temp under full load, but continues to gain a degree every so often. So it starts at 55c, 2 hours later it is at 57c, then 3 hours later it is at 59c) and let it run for at least 8, but no more than 24 hours. Then turn it off for 8 hours minimum and repeat that cycle for about 2 weeks.
Your AS5 should be fully cured and the system should run 3-5 degrees cooler than when you started
