Any help appreciated

Bought a new PC recently and assembled myself from these components:

Case: Coolermaster HAFX
Mobo: ASUS Sabertooth Z87
CPU: i7 4770k
Cooler: H100i
PSU: Coolermaster Silent Pro M2 (80plus silver)
Ram: 16gb Corsair vengeance 1600mhz
GPU: GTX780 Direct CUII OC
Drives: 3 kingston hyper x 120gb SSD's (one as a boot drive and the other two are striped)

Also running this all onto a 1440p 27inch monitor if that makes a difference to anything...

Now for the problems.. :D

I was running this setup absolutely fine with the H100i for around the month, everything performing absolutely fine. I presume I had the H100i fitted correctly as my idle temps were around 25 degrees Celsius. I tired to overclock by just a little but was disappointed with the temps so clocked back to default. Fine again for a week..

Now last weekend I left my computer on and went downstairs, I come back up to see core temp registering a temperature of around 80 degrees and climbing fast, the pc shut itself down. I checked a few things in the case and attempted to start it back up. This time the LED on the H100i had turned red and the bios had 'CPU fan error'.

I figured it might be the pump or something on the H100i so I switched it out for the intel stock cooler and used artic silver 5 as the thermal paste (cleaning everything properly). I am typing from this setup now, running fine at idle around 30-35 degrees. As soon as I put some pressure on the CPU however it just climbs and climbs until it reaches the max again. I cant even hear the stock fan speeding up... And when I say pressure I mean hardly anything, it shut itself down trying to complete the windows experience index test...

By the way I should also mention, I am not letting the CPU stay at such temperatures, I have my PC set to shut itself down at 90 degrees and the few times it has been at this temperature are only for 1-5 seconds each.

Please some suggestions, thanks for reading.

Thanks for the reply, I thought this might have been the problem with the H100 at first but why would it take over a month to finally be a problem?

Also I'm pretty damn sure I have the stock one mounted fine at the moment, it's just push pins
