Computer fan has started to become very loud.

First off hey everyone, I'm new to the site but I'm glad to be here!

I've had a bit of an issue recently with my fan/pump. As of the last 2 weeks it's been running very loudly which is strange because I've only had my PC for a little over a year and I just changed the thermal paste on it around 2 months ago. So yesterday I decided to reapply the paste and see if there was some issue with that. At first it seemed to be fine but it quickly got loud again. Even stranger though is the things that make it speed up are running videos or even loading a new web page just simple things you wouldn't think would cause problems for a fairly high end PC like mine.

I'm just curious if it's the pumps heat sink that's going out or if it's a bios issue. If anyone has any idea about what it could be it would be greatly appreciated!

First thing I would do is check your temperatures with a program like HWMonitor: http://www.cpuid.com/softwares/hwmonitor.html

Well it just kicked back up again after I've had it turned off for a about 30 minutes and HWMonitor is reading CPU temperatures as high as 90 C.
All I've done was deleted one folder off my computer and my CPU temp shot up to 90 C, I just don't understand what could be causing this.

That is far too high, I wouldn't use it until the issue has been resolved.

First thing I would do is check the connections to the liquid cooler, make sure that the pump is connected to power for example.  If the cooler is all connected properly and is fitted tightly onto the CPU, I would next be checking to see if the cooler's pump is still working, if not it may need replaced.

Well I've been wanting to pick up a Noctua fan for my CPU and get away from the whole liquid cooling pump anyways. I guess I'll know for sure if I'm still having the same issue after I change it over to that. Thanks for the help, I just really wanted to make sure if it wasn't a bios problem and my temps weren't just being read wrong by the PC.
