The CMXAF1 is the first fan unit designed for the memory subsystem that makes it into the Dominator line of products. The three 40mm tachometer-controlled variable speed fans can be set to move as much or as little air as necessary to keep your memory cool. The CMXAF1 is designed to work with Corsair's Dominator memory, allowing you to keep your system running cooler and faster.
Supreme Cooling for Extreme OverclockingThe CORSAIR CMXAF1, DOMINATOR Airflow Fan unit, features three 40mm tachometer-controlled fans to provide impinging airflow to the memory subsystem.
Ultra QuietThe three efficient fans run whisper-quietly at the moderate speed that is required to provide adequate forced air.
Pros: Out of the box to installed in the system: 3 minutes, tops. Quiet, especially when combined with a fan speed controller (or controlled through BIOS fan controls). Clearance for almost any memory, DOES NOT have to be used with Corsair Dominator series only, can be used with any memory stick that complies with "standard" height and size.
Cons: I guess if you had a couple of gorillas moving your PC around for you (being rough with it) the cooler could work its way off. The cool "mounts" to the memory retention clips of your motherboard via compression/friction only. If you wanted to make this more secure I suppose you could apply some nonskid rubber strips to the cooler finger clips. Personally, my setup works just fine as is. The cooler does stand a bit tall, if you are using a low profile format custom case this probably won't fit, measure first, buy next.
Overall Review: Does sit close to my Zalman 9500 but doesn't touch (on an ASUS P5N32 SLI Plus). On the same board an eVGA 8800GTS installed in the first PCI-E 16x slot comes very close, but does not touch, the memory cooler.
