I recently upgraded my case, fans and went with an AIO water cooler. The case looks much better and runs much cooler but not the GPU. I tried playing Subnautica and the computer locked up after 5 minutes instead of 1 minute. I just turned off the computer to replace the 3-pin fan splitter for a 4-pin fan splitter and noticed that the GPU backplate was hot to the touch. Open Hardware Monitor shows that the GPU is 56C as I'm writing this. I ran Spybot and Malwarebytes but didn't find anything.
