Just got word from Matt@OverclockersClub.com that they have completed a review on the Antec "Blue" harddrive cooler.
Here's byte from their review: The aluminum alloy harddrive cooler from Vantec, a great way to cool those hot 7200RPM drives. The package includes an aluminum alloy heatsink type structure with two 5000RPM fans mounted on it, four screws and a pass-through molex connector for power. Vantec harddrive cooler (HDC-502A) review
