CPU overheating

[SM Phoo]

Hey guys, a friend of mine wanted me to look at his PC as he felt the PSU fan was making a noise when he turned it off. 

Anyway, he fetched it round to mine and when I first turned it on, the first thing I noticed was the AIO (Corsair H100i) made like a trickling noise, as If I could hear the water moving inside it. And by trickling I mean imagine filling a cup and then pouring a a small amount into a jug.

 

Anyway, I didn't think much of it and carried on. I turned the PC off to try and inspect the noise and in all honesty, he was worrying about nothing, but when I turned it back on, I got a bios warning saying the CPU was overheating.

 

In the BIOS it does show that the pump rate is over 2000 rpm, so the pump is pumping, but the CPU was hitting 95+c within a minute or two of being on. (i7-6700k)

The only thing I've not tried is applying to new thermal paste, which I will do in a few days.

 

Could there be any other possible things to look into?

This only happened from him moving it to his house to mine. All wires are connected fine etc

 

Thanks

Firstly, where is thee aio raidator placed. The start of the tube from the pump shouldd always be lower than thee radiator tube beginning. ANnother factor could be just a dead/broken cooler. If so, do NOT run the cpu without any more of cooling, this will seriously degrade your cpu longetivity.
Respond to me once you've donee/checked these.

How old is the AIO? If the CPU was bought when it was current and the AIO was purchased at the same time, it's at the end of its life and needs to be replaced.
