To Paste or not to Paste? That is the question.

post #1 of 14
Thread Starter 
Hello All:

My question is this: If I lap my cpu and hs do I or do I not use thermal paste? I have heard some about this but not sure. Some say if the lap job is adequate then don't use tim and some say use a small amount. Has anyone tried both under the same conditions? What were your temp results for each? Thanks in advance.

im pretty sure no matter how good your skills are at lapping, using paste to fill in in the tiny holes that your eyes can't even see, or even barely will give you better temperatures.

there are always small parts on the bottom that can use some paste

I'm not sure, if you get the base perfectly flat there will be no air gaps at all so you'll get great temps.

My advice would be try both

Thanks all. Now the question is, which one? I am a big as5 fan but particles are .5 micron. Lapping will give me a finer finish than that, I think 2500 grit will give .3 micron nooks and crannies. I don't want to use the collabratory liquid pro or MX1 (the former bonds and the latter is sloppy) but was interested in the Shin-Etsu MPU3.7. Does anyone know where to get it, has anyone used it and how do you feel about it? Thanks again.

If you lap it all the way to 2500 grit, why not try without the paste and then try with the paste and see what your temps are?

I used Shin Etsu and it was OK - quite hard to spread around though

Kriegen - he's trying to work out which paste to use now

There will still be gaps in even perfectly smooth copper at the microscopic scale....
