My BLACK TRUE was bought lapped by CrazyPC. And when I had installed it, I forgot to check the flatness of it. I was wondering if I should lap it for mirror finish, since I don't remember how it looks like, but I assume it's not mirror finished. Even if not for the mirror finish, I wonder would it yield any better temperatures? Even by 1C?
I just want to know because I'm planning to do some heavy modding on my TRUE and tests the temperatures.

edit:
Since I got the CrazyPC lapping thing confirmed. I'd like to know if you guys reuse sandpaper for lapping or get new sheets of each grit everytime?

it's all about the flatness and contact between the IHS and the HSF, it doesn't need to be a mirror finish, unless you want the flash noone will see

I was thinking the same. Just wanted to make sure. Since I'm going to use at least a day to make my results. I was thinking about modding the washer mod itself.
So I'll have to wait until spring break to do that.

As for the sand paper, can you reuse it? or do you need new ones?

to get a mirror finish use some high grit sandpaper like 1000+

Once you get through a few sheets of that get some polishing compound and rub the lapped surface to get that shine. You can also use the generic white thermal paste instead to get the same results.

I purchased a pre-lapped TRUE from CRAZYPC.com

It passses the razor blade test, where you put a clean blade to it... there was zero gaps on either side. The thing was 100% flat. It even made a flat footprint of ink on my marble table, that was also machined flat.

CrazyPC does a flawless job of lapping the Heatsinks. I think you are fine and shouldnt bother touching it.

Sure I'll let you know. But I've read from a lot of people they do a decent job. I forgot about checking it so it was my negligence.

You guys reuse the sand paper though??

Thanks for the confirmation.
