I've got an Opteron 170 running in an NF4 DFI board (not sig system). With it OCed at 2.5GHz @ 1.375v, the high temps are holding me back though. It is running at 39/49°C at idle in a P180 case and a Tunique tower HSF. My ambient temp is around 75-80°F. I lapped the Tunique Tower 120 and still have high temps. I want to remove the IHS. I've done it to a 3200+ without a problem already. Do you think I will see significant improvements in temps by doing this? I figure if I'm going to Lap the CPU thus voiding the warranty, why not just remove the IHS. I know the dies are delicate, so thats why I am asking for peoples opinion.

edit: Sorry, the temps at idle are 39/49°C

It's really up to you. I took mine off on my 3700+ and I eventually chipped a corner off the core because I was checking for clearence between the core and the socket. I just lapped this Opty. Still gives a decent temp drop without the risk.

Just lap it It's a bit safer.

Lap, don't take the risk of chipping the core.

The temps are not that important. And if you lap properly it will only be a few degress over a naked CPU anyways.

Take care even with lapping.

Lap- you have seemingly endless IHS to wear away rather than risking an expensive experiment.

Well you've already done one so you know how easy it is...I built up around the core on two ends with black electricians tape level to the top of the core so there wouldn't be any wiggle in my water blocks and lessen the chance of chipping the core...If both of your cores are running at about the same temp's your IHS must be on pretty evenly and Opty's run cool anyway...Hey you can always take it off and if it doesn't drop your temp's that much just put the IHS back on....You always run the risk of killing it when you take it off though...

Well so far the polls say to LAP. I could always LAP first, then if I'm still not happy I can remove the lid later. I just think that 39/49°C is a little high for idle temps at 1.35v. If I do LAP, I will use the protective plastic and foam that came with the CPU packaging to protect the pins. If I cut the top, I'll be buying a new razor blade and locking the CPU down in the ZIF of another 939 board I've got lying around. And if I do cut it, I will definately follow ira-K's advice and build up around the cores with electrical tape.

But I still havent decided yet!

Are there any other brave souls that have removed their IHS? If so, how did it go, any chipped cores?
