Hi, I have an i7 6700 that I installed October 2015. Today while playing games, my PC shut down and booted into a screen telling me that my CPU overheated and now I have constant temp of 95 degrees celsius. I also have a Corsair H100 water cooling system for it. Can anyone help? My PC is unusable at the moment.

Unfortunately AIOs are sealed units and it should still be under Warranty. I'm not 100% sure but I think its 5 years. If so RMA the unit via Corsair.
They don't have spares for AIO units. If its out of Warranty, your up for a new one.
A cheap air cooler can be got for 20-30$ to tied you over. You may have to down-clock and drop your CORE voltage.
OOPS, you have a none "K" version chip so they are not overclockable so the system would be OK to get a replacement AIR cooler as an option.

First you should check that the H100 pump is working. One pipe from the radiator should be cooler than the one going to the radiator which should be hotter. If this is not the case then you may have a blockage or air has got in somehow. If you disconnect the radiator and fans and give it a shake and it starts to work more efficiently then this proves the case. Then RMA the unit.
You will have to re-apply your thermal paste (TIM) if its been there a couple years or more.
Use AS5 or MX4 which have excellent thermal conductivity.
Don't forget, use sparingly and apply just a small Pea sized blob to the center of the transfer plate. TIM is used to fill only the tiniest of voids and excessive paste will trap air, squeeze out the sides and cause problems.

Hey, thanks for the response. The tubes that you are talking about are neither hot or cold. Is that the issue? I also forgot to mention that there is a very loud rattle coming from the CPU / Radiator (cant tell which one). I also had the thermal paste done when I got the CPU put in in 2015 so do you think that will still need replacing?

That very loud rattle is a pump failure if its coming from the CPU region. If your cooler needs replacing then do the thermal paste at the same time.

To me it stands to reason that if the radiator to CPU pipes are neither hot nor cold then there is no thermal transfer.

So does that mean that the radiator itself isnt broken but just the pump? If thats the case, can I just get the pump replaced seperately? Money is kind of an issue for me so reducing the cost of fixing this would be good.
