I am considering this for my next purchase. It's rated at 50w, it's a submersible Peliter. I need to get accurate temps on my coolant prior, so I can see what thermal load I need first, however.
If it proves to be too high for this, I can implement another one, or I can use one of these more substantial chillers:
The CL-280 is rated at 1/10HP.

Anyone have experience with this type of cooling? I'm looking to chill the water to just above ambient so there will be no condensation at the motherboard. If I could get the coolant to 15 C, I'd be happy! The system presently uses less than 1 gallon of liquid total.
