Coolit sent me one of these for review, and I hope to have it published next week. Like you said, it looks promising, and all the research I’ve done on it shows that it works.
It’s pricey, though… like $400.
Keep in mind that the CoolIt Freezone requires a 92mm or 120mm exhaust port… If your case only has 80mm exhaust then you can’t use it.
I’ll have more details in my upcoming review of the CoolIt Freezone.
