Final Words

There are two 1U coolers we particularly recommend: the Alpha PAL153U, and the CoolJag JAC311C. The CoolJag performed the best; however, the current version doesn't ship with screws suitable for reversing the fan - which is necessary in a 1U environment in order to reach best possible performance. The Alpha PAL153U doesn't have this problem, and still provides excellent performance.

One thing many are probably wondering about is: "For which CPUs exactly will these coolers be sufficient?". There is no general answer to this question. On a 1U system, more than on a larger desktop PC, the efficiency of the CPU cooling depends greatly on the overall ventilation concept of the case. So, without considering the case cooling, it is not possible to say which cooler will be sufficient for which CPU. Even if you chose a good cooler, extensive testing and thermal monitoring of the server should be done before using the machine in a production environment.

There's one thing we can say for sure: You cannot buy any generic 1U case, good heatsinks, and build an AMD dual CPU system based on this. Using AMDs high-end CPUs, especially in a dual CPU configuration, requires an overall case cooling concept that is well-thought out - good heatsinks alone aren't sufficient. An example for an overall cooling concept that is well thought out is APPRO's 1124 760MP Server.
