Likely cause?

Basically, for my last computer I had watercooling for several months, however a few months in, the temperatures randomly spiked to 95°C and would cause a shutdown every 10-20 minutes, rest of time it would be its normal temp and run fine

I just switched it out for a air based heatsink as I didn't have time due to university, but while I'm looking at watercooling again soon would like to see most likely cause.

So any ideas what most likely caused this?

Main components I had were;

XSPC RX240 Black
XSPC Dual 750 Bay Reservoir Pump Rev2 Multi Fascia
EK-Supreme Universal CPU - Acetal Inc 775/1156/1366

I've seen people saying they only got 6 months out of their XSPC pump, would this likely to be the problem?

I'll try it again next week

The thing was it was running fine you could see the water flowing through it, but its temp just spiked for a few sec caused shutdown, restarted and worked fine, then in a bit would do the same again

Just figured may aswell find the cause as I could get it back up and running, or sell the parts on, beats £250 of equipment sitting in a box hiding away

Yeh I was using the Thermochill blue UV

I'll have next week off, so will check it then

Is it distilled water that I can get cheap to test (i.e 5 litres cheap from halfords)?

Thanks i'll pick it up next week and give it a try

If pump fails how will I know, only by holding tube to feel pressure?

Yeh with next build i'm going with mayhems

Watercooling stuff I have atm are about 1-2 year old

(was for my old i7 920)

Scotteh · 17 Oct 2011 at 15:48

No idea how to dismantle it, its in a box at the bottom of everything atm

I'll get it out next week and check.

Pump is about 1.5 years old now I think, just not had any time to do anything about it had to quickly change to air cooling so I could get on with work

Worked fine for about 6-12 months I think it was.

Thanks

Will that do the job?

Scotteh · 21 Oct 2011 at 22:39

Ok thanks i'll pick up some tomorrow and try it out

Only thing I'll need is PSU ain't it?

PSU 24pin -> PSU bridge
PSU Molex -> Pump

Ain't it?

Ok got round to it, opened the waterblock

Theres like bits of buildup in it (theres a metal plate then grooves under it + outside each edge)

Is it fine just to clean this normaly or do I need to prevent it touching specific stuff?

It's as if theres little bits of threads in it :s

Scotteh · 26 Oct 2011 at 12:44

I have the XSPC dualbay pump/res combo, so can't open it and check the pump etc as its sealed

And yeah like small threads :S Inside the cpu block theres like the grooves, a metal shield thing over it and within the middle of the metal shield thing theres a hole

Within the hole is where I found each of the grooves half full of the thread stuff

By thread I mean like, bits of frayed thread, tiny bits

I had PTFE tape but don't remember using it as I used the jubilee clips and had no leaks.

And not sure what colour it originally was but it was blue when I looked (liquid was blue so I figured it had just dyed it)

Scotteh · 28 Oct 2011 at 16:04

I could try it now, but without attaching it to PC i'd have no idea if the temps are still spiking or what, i'd just know that water was flowing.
