I have a possible problem with one of my WD20EARS drives. The temperature of one WD20EARS drive is 44C all the time while it is running. The other WD20EARS drives range between 25C to 29C. I'm not sure why one drive is much hotter than the rest. Cooling isn't the problem. I have the hot drive and the other drives mounted in a Thermaltake A2309 3 in 3 drive cooling chassis. The drive runs hot even if it is running outside the tower, mounted in the drive cooler chassis. I'm not sure if the drive should be replaced, or if I should just live with it. The drive does not seem to have any problems storing data.

Is it actually hot or is it reporting hot?

SMART isn't always accurate with temps. I once had my drives show 13-17c for a little while. Which was 7-10c cooler than ambient. If the drive doesn't feel hot to the touch, I'd just ignore it and not worry about it if you have active cooling for it.

i also got the same problem and i know the drives are not getting too hot...

so i tend to agree with this..

From your description, it sounds like the drive will be at ambient (I'd assume 20ish degrees) room temp before spin-up and yet show 44C as soon as it's spinning. Obviously, it should first report the room temp and then climb to 44C if it was really running hot. So, that sounds like the drive has a bad temp sensor. You can either just live with it or RMA it.
