GPU coolers tightness

[Shakyj]

I just pulled the cooler off my HIS 5770 and replaced the TIM with some £4.50 akasa crap that I have and it has dropped 10 degrees which is nice :D.

But the problem is it is really wobbly on top of the card. That can't be the best for heat transfer can it?

Forgive my bad English but what's "really wobbly on top of the card" mean.

it means the sink isnt sat tight to the pcb/gpu die.

if i was you i would redo it, as the sink wobbles its breaking the contact between the ic and the sink and will put air pockets in the tim which will cause hot spots on the gpu.

just be more careful next time your putting it back in and hold the card by the pcb.

I must have reseated it about 6/7 times. It still has that wobble. It is due to the backing plate not being able to put enough pressure on. I think it is designed that way. But it seems wrong to me. I was going to pick up a few O rings today to try put some pressure on if people agreed it being tighter is better.

Edit: On a side note are the small heatsinks you can get to add on to ram blocks any good?
