What temperature is ok for my hard drive

Most HDDs will tend to error out at 55c. So as long as it is around 35-50c it should be fine.

so Long as your case has good cooling, it should be fine, there really is little need to buy a *HDD* Cooler.

Realistically, just about anything from 25-45 is pretty good. 50 isn't terrible either. I'd start to be concerned both below 20 and above 50, since reliability suffers both when it's too hot and when it's too cold.
