Does anyone know of an app that can control fans on an Xserve. I tried smcfancontrol and it crashes/fails on the Xserve. Ideally, I would like to test a lower default fan speed when idle, especially in winter due to colder room. My Xserve is only 1 CPU, so generates far less heat than what it has been designed for and those tiny fans at 5000rpm are noisy. Right now, I can see when fan speed starts to increase as CPU temperature increases. So if lowering idle fan speed a bit causes no increase in CPU temperature I know it is safe. Any suggestions ?
