Help troubleshooting Coolit ECO ALC

post #1 of 7
Thread Starter 
Hi people,

I've had a machine for 18 months running fine, with an intel Core i7-970 6 core cooled using a Coolit ECO ALC.


Everything was fine till today, on boot 80% of the time I get a warning, CPU OVER TEMPERATURE. It will continue to boot into bios, but will then shutdown within 1-3 minutes. If I dont get the warning, the system will still shutdown very soon.

In the bios the temp is listed as 85 deg C, or rapidly climbing to that temp and then shutdown.

My first thought was the cooler - maybe the pump had packed up, or its leaking? I've checked, there are no leaks of fluid anywhere.

However, When I go through the power-on / check bios / power off sequence a few times, I can feel the outlet tube of the pump getting extremely warm, and the return from the radiator stays nice and cool, so it appears that the pump is working no? otherwise I wouldn't get the outlet tube heating up?

The unit makes no noise, and never has (no gurgles or anything from bubbles) - or, not that I have noticed.


I removed the unit and one thing I see is that where the thermal paste was in contact with the copper base + CPU, there appears to have been some discoloration (to almost black from light grey) in a patchy fashion, and I do not know if this is normal or not.




Anyone any ideas? - is it right to assume the pump is ok just beacuse I can feel the outlet tube getting warmer and the inlet tube staying cool?


thanks

This is a good one. Sounds like you've checked all the obvious stuff...

Yeah :/ ...

I have wondered if its a dodgy temperature sensor?

Is there any way of checking that the sensor is working at all? - I mean, I can see in the BIOS CPU temperature reading it climbs rapidy from around 70deg (I get that if I go to the BIOS after turning it on from cold) to 85, then it will shutdown shortly after - but, could the sensor be giving readings that are too high?

Nop, your pump is dead. RMA or buy a new unit. Recommend the H220 because it's the fecal matter.
Stop booting the system, you're gonna degrade your CPU. There's literally nothing there to cool it other than a 3mm thin copper plate. If the water's not moving, the heat is lingering.

Okies, that was my hunch.

and Scorpion: yeah I knew continually booting is bad, so i've done it the minimum times I could to be sure of the effects I was seeing.


Aanyways, I'm looking at the H80i as a replacement, should be at least as good and it fits in the case so yeah...

The Coolit is basically an H60 right? The H80i will be a good upgrade thumb.gif
