The fan on my PSU is always running hot with the fan at like max RPM's. I had it as a FreeNas Box running Plex Media Server. Every time a friend would stream media from my server the fan would just kick into high gear. Is this because of content rendering or it's getting too hot? I am noticing my electric bill going up. I know it's summer right now but it's higher then normal. The PSU is only 430W running a AMD Phenom II Quad core 2.3MHz, 8GB DDR2, 1 SSD & 2 Sata 7,200 HDD.
