Update:
I opened up the cooler and it was completely clogged with dirt. I rinsed it alot and put in demineralised water with a good bit of bio ethanol.
Closed everything back up and now my cooler works again. So if you have a closed loop system, it is possible to repair it! Just be carefull. I destroyed one of the screws of the heatplate and it might not be the best seal anymore.
Room temp around 20. Idle temp same. Maximum load temp = 70 celcius. Seems good for a fx-8320.

Hey guys.
I was wondering what your thoughts were.
My pc has a weird problem that I found out about today.

I got some second hand parts to build a pc a few months ago. Everything tested fine except for the onboard sound.
Temperatures at the time were fine using stresstests.

Today I started a new game and after a minute my pc crashed. After checking the temps I quickly found out that was the problem.
I haven't played a game in a week or two since I didn't have time so I don't know whether temps were reasonable beforehand.
I have a corsair H55 closed water cooling loop. I tried to figure out what the problems were.
I replaced thermal paste twice. Moves the cooling around alot to try and figure out if there was alot of air in it. It sounded like it was.
After this point I can start up my pc. Open a temp monitor and it idles at round 55 celcius. After opening internet in shoots up to 70 within two seconds and then goes back down in about 15 seconds.
Prime makes it go to 90 within 2 seconds and shutdown in 3.
I disassembled the watercooling, added some demineralised water, checked if the pump moved.
Still the same problem.
The pump makes some kind of rattling noise. No idea if the pump is moving at full speed or not.
Strange thing is the tube get's very hot, so does the bottom of the radiator but the fins of the radiator stay very cool, except the most left area get's slightly warmer.
This leads me to believe it's the cooling, i'm going to buy a cheap cooler tomorrow to check if this is the case.

But perhaps there is something wrong with another part of my system, as the cooler does seem to work.
Anyone have any idea or suggestion about this problem? :)

I have no idea. But have a bump.

i had a H60, and the pump died after ~3 years. sounds like the same happened to you. i read this happens a lot. i went back to air cooling because of that.

These quick jumps in temperatures are just normal and yes, they are real.

But your temps are high overall.

30 celcius increase for 0.2 seconds of calculation time is not normal.
And shutting down even less. :p

Yes, it is and my CPU acts the same way.

"Strange thing is the tube get's very hot, so does the bottom of the radiator but the fins of the radiator stay very cool, except the most left area get's slightly warmer."

Not that strange, and probably key to finding what's wrong.

If the heat stays on one side of a radiator, the liquid isn't circulating properly.
Common causes for that include:

  • Tubes are too narrow, creating a bottleneck and preventing proper flow
  • Tubes are too wide for the pump's capacity, so you don't have enough presure.
  • Pump is simply broken, so you don't have enough pressure.
  • Blockage somewhere in the system. (But you'd probably would have noticed that when you disassembled the lot)

Blockage could still well be the case.
I only disassembled the pump area. The rest isn't disassemblable.
I've seen some youtube video's where there is all kinds of debris in older closed watercooling systems.

I would look at replacing the water cooling system. If you've changed the thermal paste (properly, but I assume that you did that) you shouldn't have issues on the motherboard end. When the tube is getting very hot, that's probably a sign something is wrong wrong with the radiator or another part of the system. That's still a very fast time for a thermal trip though; 3 seconds is incredibly fast for a heat kill.

I would start by figuring out why your pump rattles. I dont use, nor even checked out a water cooled system, but I am pretty sure a rattling pump means the same as a rattling fan. Something is in it or something is worn out meaning it is not pumping as well as it should.

Rattling could mean a bad bearing, if that's the case then your best option is probably just get a new unit.

Mmh i have little exp with water coolings but that temp rise indicates that the watee is not flowing at all. Did you check for that? Are you controlling the pump via a voltage-reduced pin header block maybe? Rattlimg noise you say - sounds like the pump is not getting enough starting voltage to even run. Make sure the pump runs on full 12v before venturing further.

Same results no matter the header, or even directly on 12v molex.

Yep, sounds like a dead pump, if it is rattling and the water is not carried. Sadly, this is why water-cooling is risky: it is quite silent and effective, but if it dies, it dies spectacularly (air-cooling systems can still manage to cool the CPU somewhat after the fan dies).

don't you have a flow meter or anything? if the pump is dicked the water isn't going to move itself (not much).
