My two year old XFX Radeon R7 370 graphics card has been running crazy hot after I upgraded my system.
The other components I have are:
Ryzen 5 1600
MSI Tomahawk B350
Corsair LPX 2x4 GB 2666, c16
EVGA 500B (500W 80+Bronze)

CPU temps are fine (69C at 100% load). Before this when I overclocked the r7 370 to 1100 MHz it would max out at 80 degrees using Unigine Heaven. Now I run it at the stock 995 and it goes up to at least 100C (while playing PUBG). Was too scared to stress it with Heaven again.
I tried reapplying thermal paste twice, didn't do anything. Is the issue my motherboard's VRMs, the PSU? What can I do stop this thing from frying my system before I get invest in a better card?

This is what my system looks like. My graphics card seems to be over something, not sure what it is.

Tried at 900MHz, afterburner says it was around 85 which is still too high. Fans spin, they are very loud and I dusted them reasonably well when upgrading.

I made an X on the chip, I'm pretty sure I secured it properly. I applied an aggressive fan curve and now it stays at 85C at stock but the fan is very loud and when it gets dusty it will probably get hot again.
