I think the XP-120 has a base made of copper... aluminum fins and I am not sure but also copper heatpipes, and all is chromed finished.

 

If you sand the base of the XP120 you will probably end up removing the chrome, which is not a problem if you can mirror finish it.

 

Not having the IHS might be a problem, not sure but do a search on the forum (modifications & Cooling section)... i think people already did that.

 

Good luck

well i sanded the base down last night and it was not even at all where the cpu sat it was really caved in there. and there is copper under the chrome.

took me about a hour. started with 320 grit wetordry sand paper worked it till it was flat on a granit counter top. then worked it with 600, 800, 1200. and finished it with 2000 grit. all was wetordry sand paper. got a mirror finish.

drop my temp by 7c idle before was 38 after 30-31. loaded it does not get over 52c now. it help but think i might look for a better cooler so i can overclock more.

 

oh and thanks for the link. have to file the base down.

I'll give an "Amen" to the copper underneath.

A lot of work but lapping can drop the temps.

As always correct seating or contact with the CPU is the most important element.

Just for the record, guys, these 'sinks are nickel plated, not chrome.

 

True "chrome plating" is virtually extinct due to the extremely toxic by-products of the process.

Good to know... we still call everything that shines in silver colour "chromed", and its a nickel alloy which IMO is even better than the old chrome :)

 

 

Btw, yikes on that pic DGuy... if Thermalright can't produce a flat surface on their heatsinks, I can only imagine how bad the others are.

how thick of a shim??

i took my temp from 38idle to 32 just by lapping.

with a shim it will go lower?? i have good pressure on the cpu.

What are the case/mobo temps?

 

What HSF are you using?

 

52C is very high when using the XP-120, as it is one of the best available!
