CoolIt Systems RAM Fan Review


You need active RAM cooling

I have been directing extra airflow to my computer’s memory ever since RAM heatspreaders came out. I figured that if there was an actual need to distribute heat produced by the memory, then that heat could be better dissipated by some extra airflow. Nearly every DDR2 module now has heatspreaders, and DDR3’s specifications actually require them. Modules can easily reach 150 degrees, which is about the same temperature that motherboard chipsets reach, and many of them have active cooling to ensure stable performance. DDR2 modules are now reaching over the 1GHz range, requiring more than 2.3 volts to keep them stable. Active RAM cooling is no longer in the realm of the hard-core overclocker; it is virtually essential to maintain performance on modern hardware.

CoolIT Systems has recently burst onto the aftermarket computer component market with innovative products designed to cool your rig down. Their RAM Fan is intended to address the problem of hot memory while having over the “minimum requirement of flair”. The extra airflow doesn’t just cool your memory modules; the cool the surrounding voltage regulators and chipsets, which only improves overclockabiliy, stability, and longevity.

The CoolIT Ram Fan comes in a clear plastic clamshell package and includes nothing more than the unit itself, and an informational insert. The RAM ran is a simple one-piece design with no removeable parts. The device is designed to clip over any standard 4-slot DDR or DDR2 RAM slot bay. The unit’s design raises the fan slightly at an angle, which improves airflow by not trapping new air under the cooler.

The RAM fan is basically a flat sheet of thick aluminum that has been shaped and cut with a die. To eliminate unsightly mounting holes, the fan has been carefully placed with triangular pieces of double-sided tape. While this makes the fan pretty much permanent, the double-sided tape will dampen any vibration the fan may produce. It would have been thoughtful if there was some foam on the clip ends, to prevent vibration transfer between the aluminum unit and plastic RAM slots.

Power to the fan is delivered using a standard 3-pin fan header, but only the positive and negative leads are attached. The absence of the third lead means that there is no way for your motherboard to monitor the fan’s rotation, eliminating the possibility for automatic noise reduction. Also, there is no onboard rheostat or potentiometer to control the fan’s speed, either: the fan is either full-blast or off.

The clear 60mm fan’s base has pre-formed holes for side-mounted LEDs, but they are not filled. Instead, two small blue LEDs are included in the center of the fan blade assembly. These tiny LEDs do not light up the fan blased effectively, and merely look like tiny blue eyes.
