Getting new GPU

[Flomac]

There is no 1060 FE or official reference design. There are a few cards with radial cooler though. But the 1060 does not produce very much heat, a card with a proper cooling system would be fine. It also depends on the size of your case.

For the price of a 1060 6GB you should be able to get a used GTX980, which will be faster under Hashcat, so I'd consider that.
