DIY CPU water cooler

[Mad Professor]

I did indeed remove the cpu from the socket to lap it.

I just used a small A4 sized sheet of glass, and taped down some Wet and Dry sand paper to the sheet, starting at a 600grade and slowly working my way upto a 2000grade, took about 30-45mins in total, I also did end up sanding down the tips of my fingers as well.

There are meny videos on how to lap a cpu on youtube, the main thing is not to apply pressure to the cpu as you are lapping it, keep rotating the cpu, and just take your time.

As you start lapping look at the cpu heatspeader now and then, and you will soon see how bad the heatspeader is, as you will get the copper showing round the outer edges of the heatspeader 1st, once you have the copper across the hole of the heatspeader it's time to move onto the finer grades.

Lapping my CPU knocked around 5c at load off my temps.

So if you was to lap both your cpu and water block I would hope to see you running in the low 50's when stress testing.

When I was running the stock cooler and before lapping the cpu, I ran IntelBurnTest, and the temps where in the mid to high 60's.

I'm going to make cooler for chipset (I finished cutting out another one for graphic card and junction bars yesterday) ,so possibly I'll need to remove MB. This will be perfect opportunity to lap my CPU. Doesn't static electricity damage a CPU (in case touching the pins)?
