ASUS R9 270 running hotter after applying thermal paste

[Gintoki98]

What have I done wrong? At first I obviously applied too much, because it reached 93 degrees. Then I applied a bit less(less than this), and still it runs hot (reaches 89). I'm testing it with Furmark. Here's how it looked like when I opened it. I'm pretty sure screws are nicely tightend. I haven't applied so much on memory(as seen on pictures(the paste up from CPU paste)). Should i do that? The gap between the cooler and memory is huge, like 3-4mm.
Before changing it was running on 83 degrees max.

Please help, thanks in advance.

Are you sure that the memory didn't have thermal pads on them, not thermal paste? When there's a gap between heatsink and chips it usually means thermal pads are used.

Are those your pictures or just pictures that looked like what your card looked like? Because if those aren't your pictures then it means you didn't take any pictures which means maybe you weren't paying as much attention to detail as you needed to. Are the fans spinning up, you didn't mention that.

I just realised those are different. I will buy some thermal silicone pad and apply it, since it has only small layer (not sufficience to make contact) on vram. With this cooler, should I spread the paste (which I normally don't do), or just apply a dot(big or small?) ? And should I apply thermal pad on GPU around the shiny square? Please provide me a guide, it would be a lot of help.

And yeah, sorry for those picture I didn't indeed pay enough time to details, they are just reference to what I've been talking about. Yep, the fans are spinning quite good, and both with same strenght, checked by trying to stop them, I get same feeling.


Thanks for your answer!!

I would just put a small pea sized dot of thermal paste on the die, as you would with a CPU. The thermal pads should go on the memory chips, cut them to fit. There are good videos on Youtube showing this process though not necessarily on the exact model you have. Tech city is pretty good at showing this kind of thing.

Update:

I have fixed it by applying Arctic MX-2 thermal non-conductive paste, and placing thermal pads. Biggest difference is that I spread the paste, because my GPU doesn't have heatspreader, therefore paste wasn't spread nicely when I placed just a dot. Now i'm getting 73-4 degrees under full load and fan speed about 55%.

Thanks for Tech city suggestion, seen that there.
