post #1 of 7
Thread Starter 
So, i just got 2x thermaltake DuOrb vga coolers for my dual 8800GT's. I did the razor check and both of them is slightly convex'd. Would it pay off to have these lapped? Iso your opinions

I wouldn't bother. You won't be able to lap the mated surface (the GPU), so you'll see minimal return on the investment.

Nothing wrong with it being slightly convex. If it was noticeable without a razor, or was concave, I would recommend lapping it, but slightly convex probably won't hurt temps one bit.

I probly wouldnt def test it first and see how it cools and even if you do do it very little dont wanna do it to much and makes bad contact with gpu cause cant be tight enugh.

I don't think the time spent lapping would be worth the 1c or 2c drop, if any. It is already touching the die so the heat is transfered pretty fast.

I wouldn't bother. It's direct-to-die anyways, and a big part of lapping is lapping the IHS as well. I don't think losing warranty and time will be worth the possible drop. Unless you really hate the noise of the fans, and want every celsius less you can in order to undervolt them.
