You think you\'ve got problems...

EHM-0654 Murray:
On Thursday night/Friday morning (I was downloading the EVE-online client overnight) my main FS PC (a Koolance PC2 water cooled monstrosity with the current generation cooling blocks) turned itself off. When I turned it back on before leaving for work on Friday it went into CPU overheat protection mode (reached 50deg C) in under a minute and again shut itself down. Given I have my (currently) 3 PC's in a stack, I left it off and ignored the problem until this morning, when I discovered that one of the hose lugs on the water resovoir has sheared off entirely and there is almost no coolant left in the cooling loop any more! :[

Luckily (always try to see the bright side...) there is nothing remotely electronic anywhere near to the resovoir, I needed to drain it down to add the GFX card cooling block, and it was due a change of cooling fluid any how. Once I replace the resovoir and coolant (on order from the States... shipping is costing more than the parts to get them to me ASAP), I should have a fully working system again, but basically I am grounded until the replacement parts arrive and I can fit them...

Ouch, unlucky, you should invest in a PC that doesn't overheat, water and electric don't mix lol!

Watercooling is great when it works, but not so great when it doesn't work.

Yes they do Jonathan, I've mixed water and 'leccy before - only cost me a mobo :D

Anyway, lest we forget, when it is all working (which it had been for more than two years before the last disaster, which was my own fault...) I can get a constant coolant temperature of 30deg C (3200+ CPU and Northbridge only for those figures, I haven't run with the GPU in the loop as well yet) with the case fans and my main radiator fans (I modded the radiator to have a pair of 120mm's underneath blowing upward) turned to MIN on the fan bus I added; that only leaves the three Koolance fans above the radiator sucking the air out of the case and they are pretty quiet most of the time...  Like Iain says, great when it's working...

My next big step will be to replace the Koolance water-based coolant all together, and use a chemically and electrically inert liquid super coolant (3M fluorinet, if I can find a UK supplier for it...)

A friend of mine years ago mucked around with liquid nitro, NOT good, I will leave it at that ;);D:s
