Ethereum : GPU fails every day 4am due to overheating

Ethereum update: GPU fails every day 4am due to overheating


Hi folks,

I’m mining on rigs on Ubuntu 18.04 with Finminer and OC values like that 1100/2000/950.

Everything is fine except for GPU0 on one miner. Almost every day temperature jumps shortly after 4am to 511°C and miner shuts down minutes after, reboot fails. Any ideas?

Help would be greatly appreciated. I have no clue.
