I'm intrigued by water-bath, but perhaps one very easy idea would be to put the closed-loop radiator in a water bath in a small fridge which is a much quieter way to go than my a/c unit.

 

It is interesting... even putting in the ice box portion (using something like prestone winter washer fluid or a water / radiator fluid mix for the bath)

 

Just wondering how well the fridge would be able to pull down the temps and how long it would last.

 

I remember you posting this years ago when Nick was an active poster (and he wasn't so hot on the idea.. but it obviously works). The way I solved the noise problem was to move the unit into another room and use 6" flex duct hose.

I think a little fridge would work really well, and quite quiet too. I would wonder about ice water coming thru the tubes as far as condensation goes, so I'm think just a pretty good sized tub of water in the fridge, keep it at 38 degrees or so which is about as cold as the fridge part could be set too. Because of a large open reservoir you would also get some evaporative cooling especially in a fridge. All in all you could eliminate the fans (or are they involved in circulating the closed-loop solution?) and so do this w/ low noise levels and superior heat exchange I would imagine.

 

Yes, Nick swore his mission-critical flight simulator must be maintained at steady-state temp & humidity else complete disaster was looming. As Bill Maher says, 'Oh, I kid Nick" I've now done this for at least 6 years--probably much longer as I can't track time too well these days. Yes, a CPU died, but I'll stick w/ Occam's Razor and call it the 1.45v I exposed it too which intel says for that CPU was the ABSOLUTE MAXIMUM and w/ that you can expect less than full service life. It's a perfectly safe system--no significant static build up, no condensation--just a little loud sometimes but that is resolved w/ headphones if needed. Who knows, an H100 make be good enough if hey improve on the thermal design point needs of Haswell.
