Low Profile Socket-A/Socket-370 Cooler Roundup - December 2001

CoolJag JAC311C

CoolJag's "Skiving" technology with its super-fine copper fins could already convince in the September 01 Socket Cooler roundup. There, the CoolJag cooler was only outperformed by much larger coolers. CoolJag's coolers have a excellet performance/size ratio, so it's no wonder their 1U cooler performs well.

Installation

The CoolJag cooler comes with a standard clip, which is easy to install and uninstall. Thermal compound is included. By default, the fan blows onto the heatsink. It is not possible to reverse the fan, since the screws that hold the fan are too short for this.

Performance and noise, conclusion

The performance of the CoolJag unit was the best of all 1U coolers tested here. However, under the conditions in a 1U server, the best performance is only reached if the fan is reversed, which is not possible with the supplied screws. We have contacted CoolJag about this issue, and they replied that other screws would be included in the future. So, if you plan to buy this cooler in order to use it in a 1U case, make sure you buy the version with the longer screws, or get other screws separately.

With high cooling performance comes high noise; the CoolJag cooler isn't an exception - it is among the noisier coolers in this roundup. Still, it is much quieter than recent high-performance coolers for desktop systems.
