Hard drive temperatures

[Guv]

I have 4 hard drives in my PC and they usually run at about 32c, although on the few hot days we recently had they were 40-42c.

At what temperature should I get concerned about them being too hot?


There are a few case fans that make a big difference, those above temps would be at least 5 degrees higher without the fans!

I definitely wouldn't be worried about those temperatures, anything above 50C might be slight cause for concern but yours are well within normal operating parameters.
