I have a 120 mm fan blowing over my 2 HD's in my Lian-Li case, but for noise reasons I have the fan hooked up to my power supply (Antec Truepower 430) which controls fan speeds based on case temp. My concern is that the HD's seem to be a bit warmer than before. Motherboard Monitor 5 says that my HD temp is around 35-37 deg. C- is this too high? Should I be worried?
