I bet you also plan to push/test that CPU to its limits, but whats that got to do with the weather, at -20C do you plan on going outside with it ?

As for the Koolance TMS 200 there is a 2amp limit per channel GK.

I just went to dsumanik review
http://www.xtremesystems.org/forums/...d.php?t=225585, but I see you have also been there.

The more I look at it (TMS-200) the more I like it, I think I will also get the TMS-EB200 Expansion Board, as I need to buy it in from overseas,
I might as well go all out and get the optional Koolance INS-FM16 flow meter.
However I think I will use the AquaComputer inline temp sensor to monitor water temps.
