HI,

Ive got a thermalright u120 (non-x) but the thermal surface is what i can only describe as "ribbed" see pic, this is my first build and i thuoght it had to be mirror smooth?

any opinions on this? it dead level to look at, but has this textured surface.

it came with some thermal right paste, however ive also got some As5 paste as i wanted the best, any reccomendations on which paste to use?

check the ridges!!!!

Thanks for that, i will give that a go, but must buy some cleaner first.
ive read a bit on here about people lapping thermalrights, I was wondering if this "ribbed" finish is by design or poor production finnishing...

the thermalright get great reviews, and i presume these reviews are based on stock (un-lapped) coolers....so what im really asking is...

is this ribbed finnish a standard feature or have i bought a lemon!

is the thermalright paste designed to fill the gaps as it seems a bit thicker in consistency than the arctic s5?

Thank again
 
phily, i definatly feel the bumps with my fingernail, although they are very fine and uniform. should i get a refund?

Thats what I was thinking, however, i would like a few more opinions to back me up ( no offence ) as i have read some conflicting views on the thermalright surface issue.

rather than RMA'ing it i will take it back to CCL for a refund/replacement as the item is "unfit for purpose" under the "sale of goods act"

is annoys me when buying specialist items, no prep work should need to be done, the item should work stright ut of the box.
