I use my Mac for developing and as such run multiple versions and flavors of Windows 7/8/8.1 32-bit and 64-bit. I noticed with Fusion 7 the fan seems to always run no matter if the VMs are idle or if they are being used. The VMs themselves don't show any utilization and are configured nominal, 2vCPU and 2GB memory. I tried using 1vCPU and the performance was too poor for my testing purposes. I have tried everything I can think of, enabling/disabling hard disk buffering, enabling/disabling 3D graphics, removing any unnecessary drivers, disabling anything unnecessary services for VM OS. Nothing seems to change the fact that the fans want to run all the time. OSX itself show barely any load. Typically, i run 2/3 VMs at a time, though only one will be active while the others idle.

Any idea what to check? I deleted the .vmx files and created new ones thinking maybe there was a bad value, but that changed nothing.
