CPU Fan Randomly spinning at max RPM

My Noctua NH D15 starts to randomly spin at about 1.2k-1.5k RPM randomly and then going back to about 500 (as in when there is no load or when there is like 50% load). It could be when I'm doing nothing (computer is just idle) or when I am browsing the internet or playing a game.

This has only started 4 days ago and before that I have had no issues.

I have checked the cpu temps when it randomly ramps up to high RPM and they are only going up by like 4-5 degrees Celsius.
I have checked task manager to see if anything is causing random huge load and nothing is doing that.
I have checked for malware and trojans and there weren't any as far as I know.
I have opened up the pc disconnected and reconnected the fans and that didn't do anything.
On safe mode it seems to run fine.

Does anyone have any idea what else I can do to fix this????

 
Solution
It is possible the heatsink is not installed correctly, maybe one of the legs is loose and this causes heat spikes

Hold the cpu cooler to see if it is installed firmly on the cpu

If your cooling solution is installed correctly and your fan is still maxing out, I'd suggest getting an add-on to monitor your cores temperature. Use that as your base. If the fans not engaging until higher temperatures(*40c-45c = 104f-113f is a sufficient variant to engage additional cooling), then it appears it may not be a hardware/equipment issue.

If you've been using your system for 3 months, that can imply dozens upon dozens of possibilities. More than likely you picked up an add-on, or made a modification to your systems configuration with the temp increase being the result.

Having windows d/ling and installing updates while your active on your system could even be a cause. Virus protection updating itself, GPU or other devices performing updates. . . the list goes on.

Ideally if you had an Image you could restore to, that you performed prior to the heat issue, that would be able to provide you with a benchmark. If the heat issue does not exist with the pre issue image loaded, then it's definately not hardware..
