Pentium D's IHS can't remove cause between core and IHS is not termal paste,but is directly soldering.

Yep they are all epoxied to the IHS :( I have heard of some solution that people use to remove them but can't remember what it is.
 
Owned hahaa.

They've soldered on the IHS since the Northwood "C" revision iirc.

To remove the IHS you must get the CPU rly hot, around 55*C+, in windows.

Then proceed to shut down or cut the power and remove the HS/F fast, then cutting around the epoxy. Then repeating the heating up phase, then shutting down, removing HS/F, and slightly lifting on it. Do that again and again and again and you'll successfully remove it :).

got to be an easier way to heat the cpu, like putting 0.5L of hot water on it for example.
 
You really cant get water to heat up the CPU to 55*c without having the water really hot. Now maybe something like a heat gun would work a little better.

what about hairdryer???

put some thermal paste on the cpu put a 0.5L metal container and pour some heated water in.

believe 0.4L 80celsius water would be more then enough.

Actually now that I think about it that sounds like it would work. Give it a try and let us know the outcome :)
 
55C wont do jack****. Its an epoxy. To break it you have to clamp ur processor and hold it in place and then use a jeweller's torch to heat the IHS and then slice it. But it doesnt matter though , the Epoxy/solder is good for heat transfer since it conducts metal to metal. What you really need to worry about is the IHS being flat or not. If you have a flat IHS on an intel , then u are getting close to 90% heat transfer which is great IMHO. Just lap the IHS and watch how ur temps fall.

@ Nicks : Every Northwood that I have owned/seen did not have an epoxied IHS. They started doing that with a late revision Prescott. You could pop the cherry of an early rev. Prescott just like u did on a Northwood.

yeah,lapping is lower risk than removing the IHS.

thank's peeps:)
 
The soldering is not with normal solder, but silver solder I beleive. 55C wont do jack, but I have removed IHS's before. It is quite hard and with intels does not offer much benefit. AMD does not use a silver solder and therefore gains much more benefit.

BTW, you need closer to 170C.

orrrr.... you could do it the easy way and quickly hit it with a mapp gas torch :)
 
Actually frag is quite close to a good way to do it.

You take a 1/4" copper plate and clamp is on to the cpu ihs, and have foam covering the back. Heat up the copper slowly, and with silver solder bond the IHS to the copper plate, then start pulling the copper plate away and dig around the IHS base.

There are many ways, but I still prefer using a peltier.
