NOTE: This Add-In is EXCLUSIVELY for the HP MediaSmart Server, EX470 or EX475. Do not attempt to use it on any other hardware.

Think your unit is running warmer than you would like? Want to speed up those fans? When idling (i.e., not doing any "work") in normal ambient temperatures the MSS fans run at about half of their rated maximum speeds to maintain a balance between unit temperatures and quiet operation. As the workload and/or the ambient temperature increases, logic in the MSS increases the actual speed of the fans to maintain lower temperatures. Many of us have wanted increased fan speed at lower internal temperatures. Not that the HP settings are bad or even close to unrealistic, more that we believe that even lower temperatures will result in longer component life. 

We have experimented with SpeedFan and other utilities with limited success, especially since the HP logic will, at times, override the SpeedFan settings. (Discussion of this can be found in the SpeedFan thread over on http://www.mediasmartserver.net/forums/viewtopic.php?t=1236&highlight= )

Alex "Big Al" Kuretz (Yakuza, the founder of MediaSmartServer.Net) has created an Add-In to simplify control of the upper and lower exhaust fans on the HP MSS. The Add-In, MSS Fan Control, allows the user to control the upper and lower exhaust fan speeds directly or to configure the speed and temperature thresholds that determine how the fan speed should increase as the CPU temperature rises.
