thermalright ultra extreme 120 rev. C base finish?

[Fat.Clown]

has the revision c improved the base problem with the original true 120?

I did google it.... just can't find a solid answer

It looks better, but still slightly curved. There's a pretty good write-up over at HardOCP

Don't mean to barge in, but I think it's funny that this site advertises a Lapping kit with that heatsink.. LOL I've heard a lot about that contact patch not being exactly TRUE... lol

yeah.... lapping is the only way to go if you want the most performance outta those TRUE 120s

I really like Thermalright Heatsinks and I'm sure the Venomous X will be a Solid Performer. However, after reading the link you supplied I found this.

The base is also slightly raised – the company explains such a design will increase performance by drawing away heat from the center of the processor in an accelerated rate.

They just won't learn, Lapping will still be required.

Pardon for my ignorance but what is lapping?

It's when you smooth the surface of a heatsink or processor using varying grits of sandpaper so they make better contact. Better contact means better heat transfer and lower temps . Here are a few vids so you can see what it entails (thanks to Slay for posting them):

lapping your heatsink is easy, just time consuming. The procedure is the same whatever heatsink you use


Here's a 2-part video on lapping your cpu. It's easy to do, you just have to be delicate

Thanks a lot. By the way, does the NOCTUA NH-U12P SE2 needs lapping?

It shouldn't. You can check it for flatness with a good Straight-Edge (a new utility knife razor blade).

If it's flat, but lacks a mirrored finished, you can always just polish it up with some 1500-2000 grit sand paper. But it's not necessary
