Mount a P4 IHS on your Dothan!!! Protect the core!

[charlie]

So here it is... thx to a fellow XS member I have a spare P4-IHS from a 1.6 Willamette.

When you first plop it on top of the Dothan core, you see the IHS floats above the pcb maybe 1mm. So I looked at how Intel does it. They put a bead of black silicone (rtv) around the base of the IHS. I believe that Intel uses a press to install the IHS to the core of their P4. After a few hours the press releases the CPU. The thermal paste is well "squished" between the IHS and the core and the IHS adheres to the pcb with the silicone stuff.

So I did the best I could, using a 3 pound brick of copper to be my "press".

Here's the project:


Here's the bottom of the IHS stuck to the heatsink after testing for contact...BINGO!


and here's the finished product... I could have taken a qtip and smoothed the silicone so it was "prettier" but I just wanted it "square" and level...


now I'm just gonna let it cure overnight with the weight still on:
