Last week I got some great deals on the used market. I managed to sell my old 5600x for a 90 euros and my 6800xt for 400. I really wasn't looking to upgrade from my 6800xt but found a great deal with the 7900xt. I managed to get the 7900xt for 480 and 5700x3d for 130 both used. So all in all I spent 120 so I am very happy with that.
There was however one big issue and that's the temps of the 7900xt. This was actually the reason it went for cheap because the previous owner rma'd it twice (1st VRAM issue, 2nd time for temps) before he decided to just get a 4070TI super since he didn't want to wait weeks again.
On stock with furmark it went to 90+ while regular temp was 58ish. Delta was damn near 35 so I undervolted it but even with an UV I couldn't really control the temps. This was when I decided to just repaste it but I had never done this before. I bought some pads and grizzly extreme paste but sadly i'd have to wait a week for it to arrive.
I thought screw it and just repasted it with some MX6 I had left and left the stock pads on (they looked great anyway).
Temperatures have been amazing since. In the Witcher 3 for example at ultra RT, ultra wide 1440P, the hotspot dropped by 25 degrees (before 87, after 62). I don't know if it will stay like this but I ran a few benchmarks and gamed for a few hours the past few days and I saw great improvements in pretty much everything. The highest delta I've seen was 16 in furmark, while gaming it's more like 12 now.
Only my memory temps are the same old but that can't be helped since I didn't do anything there. They don't look that bad to me anyway (75ish while gaming).
Now I am just pondering do I repaste with Grizzly and add the new thermal pads when it arrives next week for even better temps? Honestly I think I'll just leave it be for now since it looks like MX6 is great already.
Just wanted to share!
