CPU running hot all of a sudden for the slightest process.

A few days ago my PC was running perfectly, then Windows 10 forced me to do an update and then the good times ensued. After the update completed Windows wouldn't allow me to get past the login screen, I would login and it would just bounce back to the login. So I reinstalled Windows 10 just like it was before, ran the same update and it installed fine. Once I started using my computer after the update I noticed my fans would go full throttle any time I did pretty much anything, open a file explorer window and the temp jumps to about 50°C and the fans go full speed, sometimes it just does it spontaneously. My idle is currently about 30°C,which was pretty normal even before the update but I never saw jumps in the temp, especially not up to or over 50°C. I opened my case up and cleaned any dust but it hasn't remedied the problem whatsoever. I was thinking it may have been Windows but I tried Ubuntu and it does the same, and even does it at the UEFI Bios. My next step would be to reseat my CPU cooling block and replace the thermal paste but the paste should be fine, it's only just over a year old and I also would need to go out and buy new paste. I'm hoping it isn't too serious, I haven't had any crashes or shutdowns, but my computers speed has slightly reduced and it gets hung up on processes fairly frequently. Any help or suggestions would be great!

My specs:
i7-7700k, not overclocked
Corsair H100i V2 liquid cooler
Asus ROG Maximus IX Code mobo
EVGA Supernova 750W Gold PSU
16GB G.Skill TridentZ DDR4-2400
Asus GTX 1070 Turbo GPU
Samsung 960 250gb NVMe SSD Boot
 
Solution
Okay. Restore bios defaults and re-install Corsair Link, to make sure there is not any auto OC feature enabled. If problem persists we ll have to double check temps and stress your cpu.
This cpu is notorious for running hot. 50 C is not even warm really and yes it could be hitting this temp for simple browsing. Are you sure it really started happening now? Which fans start spinning full throttle?
You can try inspecting your bios monitoring settings and tweak fan speed settings there. You can also revert bios defaults and see if it fixes the issue.
How do you monitor cpu temps?

I'm sure it only just started happening yes because all four fans on my radiator spin at full speed which is quite audible, and that never used to happen unless I ran a stress test. I use the LED Temp readout on the motherboard itself to monitor my temps, mostly. For software I just use Corsair Link since my cooler uses it anyway. I never had an issue with heat before now, not even the slightest, even when playing a game my temp would only readout about 40-47.

Thanks a bunch! The BIOS reset worked, fan speeds and temps are back to normal. Not sure what the heck happened there because I didn't even tweak the settings for anything to change.
