So, I finally did it. First I lapped both the cpu and the heatsink until I could se my reflection in them, I used 400, 600 and 1200 grit sandpaper. Then I applied Arctic Silver 3, as described here
, a link MrMsyvc hinted about in another thread. I have only been running my computer for an hour now with this, on artic silvers homepage it says that the cooling will improve during 200 hours. It also says that you shouldnt put it in your mouth, in case you wonder.
Remember, my computer probably isnt representative in measuring the effects because mine was somewhat undercooled before, running a 3.06GHz HT 5660. However it look good, I ran CPU burn for 20 minutes and it reached 66 degrees, compared to 83 before. A sidenote, CPU burn only uses 50% of the cpu according to task manager, probably because of HT, when I fire up another instance to reach 100% cpu, the temp decreases! Anyway, it doesnt seem to have affected the idle temp very much. I tested to run the fans full speed at idle, using my fan control program I havent "released" yet, the temp decreased to 37, compared to 39 before.
