Stock Opteron heatsink thermal paste no good?

post #1 of 5
Thread Starter 
I'm going to try my stock Opteron 165 heat sink. There seems to be a lot of thermal paste. Should I wipe it off, lap it and apply AS5 of just leave it.

(I accidently touched the thermal paste on the heatsink and got a finger print in it)

i say lap it with as5 i got a pretty good difference of about 2-3*c from stock to as5 on everything

Just a question, what grits sandpaper did your use?
Did you use metal or all purpose automotive paper?

and just a little dot of as5 or spread it out to the whole IHS?

well i have not lapped mine but when i apply as5 i spread mine out all accross the chip but most people say it is better to just put a drop and put it on.

Since you've already touched it (accidentally), you'd probably be best off removing the stock TIM completely, then putting as small an amount of AS5 on the IHS' middle (about a grain of uncooked rice) as you can manage.

When it comes to TIM, the least possible amount that you can use, the better. Less is more, in other words. Excess TIM increases thermal resistance and impedes thermal conductivity, which leads to hotter temperature readings.

Hope this helps!
