I am using a corsair h100i with the latest updated software, it is set to "performance" and the pump is running ~2300 RPMs (says the interface). I have an intel i5 4460 with an ASrock H97 Anniversary motherboard, 8g RAM and an R9 390 video card inside of an NZXT s340.

This all started yesterday where I spent the whole day playing computer doctor. I woke up to my computer being off (which is weird because I don't shut it off before bed), so I assumed we lost power in the middle of the night and then when I turned the computer back on it was throttling itself and basic processes were taking forever in just windows or opening up tabs in Chrome. I downloaded HWMonitor and saw that my core temperatures were reaching 90c+ while basically idling (Bios also read 90c temp). So, I spent the next few hours with the computer off, cleaned off old thermal paste, put new paste on... started it back up and nothing was fixed. Annoyed, but I repeated the process with a different thermal paste application process and now it works fine while idle (still 40c idle), but when I run prime95 blend torture test the temperatures range from 45-90c and it only takes it about 20-30 mins for it to reach the max temperature and in the first 5 minutes the temp jumps up pretty quickly.

I have my theories about the potential problems, but I am coming to this forum because I have lurked a long time here, and usually find great quality troubleshooting help.

This is my first time using HWMonitor and Prime95, but if I can upload anything that would help find the culprit of this issue please let me know and I will do so.

edit: I just wanted to say prime95 has been running for ~1 hour and the core temps range from 48 to 85c, which still seems high, would love to figure this out so my computer can have a decent lifetime.
 


The fans do speed up, I check them through corsair link and can also hear them. I often switch the fan speed if I am just watching movies or messing around to quiet or balanced, but the difference between those and performance can be heard.
