I just bought the XFX 390, it is a nice cooler, and while not a very large overclock, I have an extra 100mhz on it without increase voltage. It runs pretty cool as well, in BF4 I don't pass 61c in intense moments.
*EDIT*
Misread and thought this was about a 390. Although i'm assuming if the cooler works good on the 390, it will work at least as well on the 380.
