Ultra Fit USB 3.0: Excessive Heat

I’ve got mine, a 64 GB Sandisk Ultra Fit 3.0 yesterday (SDCZ43).

Completely agree with others that this USB stick runs too hot! I also noticed that the performance dropped when it gets too hot and resume after several seconds passed.

I share the same concerns like others that this USB stick might somehow damage my USB 3.0 port.

I had the 16 GB Sandisk Cruzer Fit 2.0 and this one runs much cooler. Is it anything I can do to get rid of the heat issue rather than return it?
