Built a mineral oil submerged PC, now my system randomly black screens

[BlindGuyPCs]

Hello. I recently submerged my PC in mineral oil, and despite temps not being too hot, it'll randomly black screen while playing games. It doesn't happen during any GPU stress tests (at least running Heaven for an hour, it didn't.). This happened in Fortnite, Crab Game, GTA5, and I'm not sure why. I tried undervolting my GPU, didn't fix it. It's in a 10 gallon tank, with a d5 pump and a 240mm rad hooked up. Temps at max hit around 81C, but normally 60~ C. Any ideas?

I should mention, I've made sure the pump at least works, and there's flow. 

 

I saw in a Toasty Bros video, they used a significantly more powerful pump. Should I consider that too?

 

Edit, forgot to mention the specs. It's a Ryzen 5 3600 and rtx 3070.

did you checked if the processor was overheating too?

Not as thoroughly as the GPU, but it seems to hit a max of 65C. 

 

I should mention, this testing was done on discord, and I could still hear my friends talking, and they could hear me too. The display said it couldn't detect an input, even when removing and reinstalling the cable between the monitor and GPU

Try reseating the gpu

Also tried updating GPU drivers, that didn't do anything

tried pressing windows shift control B yet? ... resetting GPU drivers

Sadly no luck. Tried a new pump, that didn't help. 

What I DID see, however, was this Aida64 reading

 

I'm curious to know why the "hotspot" is so high? maybe I need to repaste?
