Sure, I'll try that method again and let you know of the result. I've just spoke to Sapphire about it (didn't tell them that I've reapplied the TIM, just told them that the card was overheating and crashing) and they told me to send it directly to the retailer and let them have a check.

Spreading the TIM will only make it worse. i have seen this before there a few things that cause it. 1 thing that can happen is the heat pipes can go bad. Another thing that can happen is something gets tweak or warped and the heat sink doesn't make proper contact. In cases similar to this they either RMA the whole card or replace the cooler. I haven't seen a case where replacing the cooler hasn't worked. Replacing the cooler does have an upside as you can upgrade to a better cooler.

Really? Hmm, hopefully this doesn't get counted as physical damage. It would be so much better if they just replace the cooler cos then I wouldn't have to go through that 6 hours of find an stable overclock again.

Coolers can bad with out even being touched. I think what happens is the seal goes bad, they are vacuum sealed after all.

There's a seal? I've never noticed it but that might explain why I have to apply slight force into lifting the cooler off the core.

that would be the paste causing the vacume so there is at least a decent seal.
as someone posted above how are you installing the cooler.

put a small amount of paste on the gpu place the gpu heatsink upside down so the part that meets the gpu is facing up and place the card ontop and ensure you align the 4 stud things on the cooler with the holes. if your putting the hs ontop then moving it to do the screws you could be moving the cooler and ruining the seal

tighten your screws in a x pattern. get one to grip in then do the diagnal corner then the other n other and tighten a bit and move on



so do 1 then 3 then 2 then 4

First, I slightly tighten 1, not screwing it in completely, but just so that it doesn't move. Then I do the same to 2. After 1 and 2 is in, I'll screw in 3 and 4 using the same method. Then I would tighten each of the screws in a diagonal pattern so its like 1, 2, 3, 4. Have I done anything wrong?

if thats what you already do then no thats right but do you put the paste on the chip the cooler ontop and then turn it over to put the screws in??
if so try the way i noted above as you maybe creating a seal and then disturbing it when moving the card and allowing air to get into the gap

Yes, I put the paste on the chip itself, not the cooler, and flipped the card around so its laying on my heatsink. I'll clean the card up and give your method a go. My main concern was that I wasn't using enough thermal paste because everyone seems to be using a pea sized drop. But when I tried using the pea sized drop, everything would just ooze out and cause a mess.

a pea size would be ok for a nvidia gpu as the ihs is bigger where amds just have a exposed die/core. you literally want a small dab in the middle. when you take the cooler off up a pic of what the spread looks like.
