Yeah I have been using it stock for months so I can compare. The new mobo is just a replacement for my Asus board that died not a new build.

I didn't lap my CPU that's make me too nervous. Screwing up a 20 cooler is a bummer but no big deal $100+ CPU not so much.

Great, I would love to see how that works out, knowing the befor and after temps will be great!

I can't agree more on the CPU lapping...that bother's me alot! I dont have the money to wast on a new CPU cus i roughed up this one lol.. when I bought my S/A, one the the nice things about it is the mirrior finish bottom no lapping needed

Ran into a bit of a problem. Mobo came and was doa. This is the third p55 board I've bought that died or arrived with some problem. Each was a different brand had an entirely different problem. I have no idea *** is going on.

At any rate I don't think I will be able to post the temp results for a while if ever as it's looking like I may just be waiting for a new sb build.

:O That's too bad!
I built my first full computer a couple of weeks ago... guess I was lucky with a good P67 board!

I have read most of the reviews and the results look good for a sub £20 HSF but would the results improve enough to warrent lapping the HSF as most pics show the bottom is not flat due to the pipes and base block.

I have some MX-2 thermal paste to apply from my older builds also.

So worth getting some sand paper today for a lapping session tomorrow?
Don't lap it. It should perform fine with your setup.

ok so i got another p55 board not really a great one but I was able to test things out.

Before lapping i was getting a max of 73c at 1.4v 4.32ghz at ambient of 20-21c. post lapping I am at the same temp but ambients this week have been 24-25c So looking at a 3-4 degree drop. I used the same paste, application technique and fan setup both times. Idle temps show the same results.

When i was sanding it I noticed the base was fairly concave at the center as all 4 sides reached polish well before the center. Additionally I noticed when applying paste this time it was easier to apply evenly using the credit card method.

I think this is probably the reason for lower temps as it allowed for less paste and more even contact.

This pc is probably going to be downclocked a bit and then its going to a famly member who only has a crappy laptop. Thinking of a 2500k rig in the next year or so for a new benching and testing rig.
