I just ran a test using HDD Temp and Speedfan and it's reporting that my Hitachi 3TB hard drive is operating at 239C+ temperatures, even when it's not really doing anything. My Western Digital Caviar Black 1TB seems to be fine though with around 46C+. I'm using the default fan that came with my Cooler Master 922 HAF. As far as I know nothing is blocking airflow and they're more or less positioned towards the middle top and bottom of the fan. Why is it so damn hot?
Yep it says 239C. I just touched the hard drive and it feels pretty cool so I'm thinking it's the wrong temperature. I even put a fan to the front fan and to the side of the bay and the temperature didn't change at all so I think it's the sensors.
HDDs very rarely hit above 40 C. If it feels cool, just ignore it.
One of three conditions exist:
(1) faulty sensor (normally not)
(2) Programer does not know the correct location and is returning a bogus value. In this case they will report a "rail" value. This often happens on some MB/software combinations when looking at the +5/+12 Volt rails. For example if you see 8 V or 16V for your +12, you Know that is a incorrect value (Computer would not even be ON) and the software limits the reading to this value. Most common cause.
(3) Program is using an incorrect algorthim to calculate the value.
Thanks for all the replies, since the primary HDD was reporting about 46C I'm assuming the secondary was close to that value too. If anything, I was running them on a case with less cooling before and I had no issues.
