[SOLVED] PC overheating and shutting down ?

[Boringtuesday56]

A few days ago fan speed increased randomly to 5k rpm and stayed there and core temps were pushing 90 on idle. I checked other threads and the advice was to clean every fan and reapply thermal paste which I did, small amount and made sure heat sink was seated flush.

I thought that would do it but things are now worse, computer stopped booting windows and gfx card got no signal. When I did finally get windows up none of my components worked and it shut itself down after a minute so I'm hesitant to try again. Any ideas would be much appreciated thankyou!

Other info;
System was fine for a year before this where I replaced a psu for a Corsair TX650M.
I'm unsure of the model of the cooler as I was given the computer but it is a corsair water cooler.
GA Z87 HD3 Gigabyte mobo. i5 processor.

Apologies I'm honestly unsure of the exact specs I was given the pc a few years ago and I can't boot it up to check. Its an intel cpu i5 I think, 16gb DDR3 and the cooler is a Hydro Series™ H80i. Mobo and psu are above. It has two exhaust fans on the top and two intake fans surrounding the liquid heat radiator block.

Thermal paste is Halnziye HY510, didn't realise there were different types?

cpu i5 I think

go to task manager then performance and click on cpu, you will find what's your cpu name.
also did you tried to use a heatsink tower and a good paste?

Well, there is alot of pastes in the market, but for me, the best performing and best priced is Gelid GC Extreme and Arctic MX4 or MX5.

It's an i5 4670k. Any help would be much appreciated

Probably the H80 watercooler has come to the end of its life and needs replacing

Was tought about that, try to use a cheap cooler like Gammaxx 400s and see if there is any differences.

Yes you are both right, a friend came round with a spare cooler to test and temps all normal. Thankyou so much I'm sorry for filling up the boards with this problem I had no idea how old the cooler was! Thankyou again!
