I bought some silver thermal paste from Radio Shack and it looks like it's probably re-labled and manufactured by SVC. I went to the SVC website for tips on applying it and they say not to spread it because that can cause air pockets. http://www.svc.com/article-thermal-compound.html

EVERYONE else says to spread it out. I did that last time and the temps are slightly higher than they were when the machine was new. It's an AMD Athlon 64 3200+, Socket 754. I always keep it meticulously dust free and clean. Right now it idles at Case temp 48, Core temp 52, Ambient 37. The room temp is always about 26. I know it's not overheating, but under load the core gets up to 60 and sometimes higher. I don't think that chip is supposed to go over 65, but I want to stay as far under it as possible.

Any opinions here at BC about the method of applying the grease and the temperature range I'm getting?

Thanks.

On the newer processors with the heat shields, they say do not spread it
That's the way I did mine with no problems
I've also spread it on

I spread it on all CPU's.
Usually the temp will drop 5-7C in about 3 weeks as the thermal compound "sets" .
It doesn't set like glue would [anyhow it's not supposed to] but will "cure" & cause a temp drop.
OCZ StealthXstream 700W,Gigabyte GA-EP45-UD3R , E8500, Arctic Freezer Pro 7, 3GB G.Skill PC8500,Gigabyte Radeon HD 4850 OC [1GB ], Seagate 250GB SATA II X2 in RAID 0, Samsung SATA DVD burner.

Best thing toi do is get like one of those gloves doctors have put a little dot on the center and just spread it towrds the outside.. Paper thin..

If you want to go even further gets some High grit sandpaper and sand the cpu slowly until you start to see copper. Then spread it on and you will get much better heat resistance!!

As for the heat yes 60c is in almost dangerous range,, Amd takes the heat better than Intel.. So it is ok to get to about 70c under really heavy load

Yeah, I guess it slowly flows and fills in all the micro gaps and pits; makes for more complete thermal conductivity (not resistance). I do have some un-powdered latex surgical gloves, I may try that for spreading it.

After reading these answers, I'm going to spread it. Thanks everybody.
