Hardware Crystal Disk Info and HDD Temps

[godreborn]

I'm not sure if this is cause for alarm, but two hdds I Have plugged in are showing temps of 51 degrees C. it's marked in red when you look at the temp directly, but crystal disk info says all hdds are good. it's only when you click on the hdd, does it have the temp inside a red oval. should I be worried about this? they're running hot, but not that hot. I think 50+ is where it shows red.

generally i've found anything from 5 - 55c is fine you should only really start worrying when they hit over 60c. If you can try and get some ventilation in there an extra fan never hurts - but its all a matter of manufacturers tolerances too
