Removing the "cap" on my CPU

post #1 of 8
Thread Starter 
I've heard somewhere that this supposively lowers your temps if you can remove it. I'm not sure what it's called(thermal cap, cpu plate), but it's that silver covering on most CPU's. If this really lowers temps and is safe for the CPU, how exactly do I do this?
Sorta like this:

its called the IHS, and it spreads the heat evenly to your cooler.
however you can achieve lower temps if you take it off, and cool direct to die,
if i were you i wouldnt reccomend it unless you really need to, it voids warrently and leaves the chip open to damage just from a moved or knocked cooler.
also it can be quite hard to take off so just make sure you are carefull.
Theres a few threads laying around on it
good luck lol

Just buy some sandpaper and lap it, I wouldn't risk killing the CPU

How much lower are we talking here?
I really don't care about the warranty on this old processor anyways, but it's summer and I'm idling 40-43c and loading 56-60c on 1.44v

if i were you i would just try lapping it first, as it is not expensive.
then if that dosnt work, then maybe remove the ihs

I am unaware of how this is performed on a P4, sorry.

I do know that, yes, it lowers temps, as it is the best possible transfer of heat, better than a lap job.

You will, however, run into some conflict with your HSF, because this lowers the chip and its contact with the HSF. You will have to shave down the stands on the HSF until clamps down tightly on the lower rising CPU.
