I have an HP server Windows 2008 Server OS. The fans are starting to run like crazy every once in awhile for no reason. It started 3 months ago. They start slow, and then keep blowing harder and harder until they are on full and they stay that way for hours at a time until I reboot. It has been in the same environment for 1 year and now this is starting. I placed the server in a different location and the same thing is happeining. Any ideas?
