Overheating Problems, Replaced Cooler

MyComputerAlwaysScrewed · November 5, 2019

So I had heating problems before. I actually posted here about it a while back and I was told that my pump for my radiator was broken. That would make sense, I had a 2-year-old H115i and I was getting 90+ degrees C on just League of Legends, super easy to run game, and 60 degrees C idle, room temp is 25 degrees C.

So I now recently replaced my old H115i with a H115i Platinum. When I run my machine, everything is fine anywhere from 20 seconds to 2 minutes, then things start to all apart. So on startup, it immediately leads me to UEFI saying that I have a temperature problem. When I check in BIOS, my CPU temp 89 degrees C and keep in mind I'm not playing or doing anything, this is literally just on startup. Then, after, my PC proceeds to instantly shut down without warning. So far, now, I have only been able to make it into BIOS once (I have to turn my monitor on/off every time I start up for some reason which never happened before, because of this, it takes a while to get into BIOS), but I have attempted around 5 times and 4 of those 5 times my computer immediately shut off before I could even make it to BIOS. I don't know why the computer is shutting off, either I have a short on my motherboard or the temperature perhaps?

Fan speed on startup is very slow and then rapidly picks up as if it knows my CPU is very hot.

I have a few guesses now:

Faulty CPU (but I doubt it otherwise I'm pretty sure the computer wouldn't even startup)
Faulty setup for new H115i
Motherboard shortage to explain the sudden shut downs, not sure how this would happen though, I was working on floor, barefeet, with antistatic wristband connected to grounding prong on wall outlet

Anyways, I'm not sure what to do now.

Very important edit: I made it into Windows, past startup, extremely slow. Was like this for about 5 minutes, couldn't get anything open to check temperature, and then PC immediately shuts off again.
