Just got my u-120 X and I have to say I'm a little puzzled. The base where it should contact the heat spreader is not smooth at all, it's actually grooved! You can see a scratch which is where I gently ran my thumb nail over the surface; I could feel the rough edges. Is this normal? If you own a u-120 or u-120 X, is your HS like this?
Have a look for yourself:
Looks like you might wanna go out to the store and get some 600-1000grit and take that baby down a bit and smooth her out
Well, I'm wondering if this is the way these are designed to be? Anyone else out there care to comment if you own an u-120 or u-120 x (or even another brand of hs all together).
I remember back in the day when I got my XP-90 it was like this... I didn't like the looks of it so I just lapped the crap out of it to a nice mirror finish
I have a Ultra 120, It had that similar base with a unfortunate concave in the middle, I lapped that baby down to 1500 grit
Dropped my temps like 2-3c degrees more than unlapped
Work and School, Work and School, oi!
its normal,
Lap it. Many heatsinks seem to come kinda rough. I guess the TTBT was notorious for a bad finish for example.
Besides, the nickel plating just gets in the way of heat transfer

sweet jesus, why does that look so uneven on that one side?
It's hard to tell from the pic if it is or not. If it is flat then you would only need to sand out the grooves.. unless you wanted to get down to the copper, not really sure how thick their nickel plating is tho. lap it and post results!Originally posted by Spawne32

Thermalright purposely keeps the finish like that, it actually allows the thermal paste to do its job, and fill in the grooves.

Anymore pics of the cooler? install pics maybe?
TIM is suppose to fill in the microscopic contours not the grooves the 120 have. The more contact with the IHS the better and the grooves get in the way of that even with TIM filling them in.
I can do a few tomorrow if you want. I did a real sh*t job with the wiring. I just wanted to get it in there and test it. I'll clean it up and do the pics in a few days.Originally Posted by james111
Nice camera, you can really see the grooves. Btw, lap time!

just got my extreme in today. Mine looks very similar. Wondering if I should lap it...
Test on your system, and if you don't like the temperatures you can lap it.

No need to modify it, the tech said it's by design. I have pretty decent temp by the way knowing that AS5 takes 200 h or so to "break in"
mine thhermaltake extreme is flat not concave like yours
I must say this is a pretty sweet pic, even the background matches. If Thermalright could photoshop that scratch out, they could use that on their frontpage
Thanks for confirming my previous post.

Thats what ill do!
your not seriously suggesting what i think your suggesting are you?mine thhermaltake extreme is flat not concave like yours
don't really see how a grooved base could be better than a flat one and don't believe everything a tech tells you about a product it doesn't mean it's better. It takes longer to machine a mirror finish than a grooved one, only testing will tell tho.. so far they all look really good

I don't see how it could be better either to be honest with you. I just go with what Thermalright says because I personally am not an expert in heat transfer. But at the same time, I think Thermalright could have easily put a nice mirror finish on the base of the HS, considering the quality of all their Heatsinks. I don't know... Its just a brain teaser for me though, because when I get mine its getting laaaaapped!

Why the hell do Thermalright's sinks come with such a
I machine 1 tonne crankcases for diesel engines, and and the finish is better.
