Great review! What are those heaters? That is a pretty cool idea.

I bet if you used some 3000rpm Ultra Kaze or Deltas you would begin to see the GTX really shine, but no one runs that 24/7 so...
The Magicool Elegant results are pretty shocking. I really didn't expect that. How much do they cost?
Your results seem to confirm others but with some other rads we haven't seen before. Good job!
