The setup is (basically) complete!

Dr, I love your new setup but if you are serious about cooling shouldn

Ha, no iWater, just Ethylene Glycol.


In my last job i
(re)designed a watercooler for a 50/100kW electric car charger. DC
converters put out 4/8kW of heat (1/2 modules). We installed them in
places like Norway and central Germany, so had to use Ethylene Glycol at
up to 40% (freeze point ~ -30C or so). But its thermal transfer ability
is less than pure water (maybe 5% or so), so when we installed them in
warmer places (like Istanbul, or the test setup in the office i'll
attach a pic below) we only used 10% Glycol to get the heat transfer
more efficient.


But we didn't use any fancy coolant stuff, we just
went to the hardware shop and bough 20 bottles of no-name brand car
radiator fluid. If it's good enough for a 100kW that probably costs more than $1/W, it's fine for me []

As for the box, I might resurrect the box I originaly
bought for my Pentium2, it's still in one (near enough) piece. But like I
said, the side panel of the case doesn't fit on properly, especially
with the water tubes, so no proper air movement. Found a pic of my last setup (shortly before demolition), with the greenish glycol coolant i had to throw out last time. You can also see the relay i put in line with the 240V for the pump, to two wires plugged into a fan-header on the motherboard, so the pump switches on when the PC starts.

I hate to think
what it's going to be like in summer, we get up to 47C here in Adelaide
too in summer. And my garage has no cooling, it was designed as a
garage, single brick walls, half insulated tiled roof, west-facing
windows, and a fan. I hope i've bought my new house by then. Damn, the
monitor puts out some heat too, 120W on normal brightness, i can feel it on
my face within 1' away... yeouch
