Msi x470 Gaming Plus Max - Ryzen 3600x
4 fan rad + 2 fan rad - loop running well
Ran with waterblocked RX 5700 for months without issue, always mining while using net etc. Temperatures nice. Then with waterblocked 2080ti without issues.
I got a waterblocked 3090 (working fine in other PC). I put it in slot 2 with the 5700 in slot 1. Providing PCIe side connector power with a 500w PSU. But it didn't work well, gradually fading in Hz then failing to be detected. I put it down to the EVGA G2 750w supply not being able to manage the extra 75w PCIe slot power. So I put a EVGA G5 1000w supply in, 5700 ran fine the first day it was in.
Next day I moved the 3090 to my other PC with supplementary power from the G2 (works lovely).
I put 5700 top slot in the MSI and 2080ti second slot (8x8). The 5700 was fine but the 2080ti had become super hot and thermal throttled. I put it down to something dislodged in the block so I redid it (although nothing seemed amiss) and repasted it, or a conflict.
I then put the 2080ti top slot on its own (in loop) and it was still super hot after trying several things. I took it out and put the 5700 in top slot on its own. It too was and is now super hot. I have tried everything I can think of software and BIOS.
What is going on?
