50c temp. for external hdd is ok?

[HuNTeR-]

cheers to all,
in hdtune it shows me around 50-52 degrees during transfers and 43-46 in idle.
Is ok to have 50 degrees for a hdd in transfer mode? 50C is not too hot?Is there an external coling solution for that?
thank you,
model hdd is : WD Elements 25A1

This is what I use to keep temps down. 50 is okay, but when you can run it cooler and this extend life of your components, why not.
