Should I Lap My CPU With This Sandpaper?

post #1 of 18
Thread Starter 
Summer is here and my temps are skyrocketing!

For a while now my Q6600 has had a temp readout of about 38-38-34-37, which makes me think that my Tuniq isn't making correct contact. I have some 100 and 150 grit aluminum oxide sandpaper and I'm wondering if that is a fine enough grit to use on my Tuniq and not just wreck it.

Rep to everyone that helps.

It sounds like it would be fine, but I would go atleast to 800grit.

So I should just go get some finer grit sandpaper?

What's your room ambient temperature?

Regardless ... those idle temps look like gravy to me. No worries.

But if you want to lap, then starting at 150grit is no problem. Just finish things off with 600 and possibly 800 after that to at least get things semi-mirrored.

Again, though ... depending on your overclock ... I think anything in the 30's at idle is fine.

My Q6700 @ 3.8ghz is currently idling at 37C. A perfectly alright temp I think.

Have fun.

If i remember correctly, you start out with either 400 or 600 grit. I think it was 400, then 600, 800, and then 1000 grit. Its best if you use wet sand paper, so you can lubricate it with water.

I'm not worried about the fact that I have 38c temps, I'm worried that there's a 4c difference in temps (and it gets to be about 8c on load) and that is a product of bad contact (I've reseated about 4 times with different techniques each time).

While those temps sound alright, but unless you post your ambient temps, we don't have an accurate display of how efficiently your air cooling is working. Post ambient temps in comparison with your idle/load temps so we can make better judgments.

It's about 26c. And once again this isn't a question about temps it's a question about lapping.
