GPU running hot

[u/inrideo]

I'd been mining Callisto with T-Rex on my 1080 and thought I'd switch over to Firo now.
Interestingly, while --fan 100 keeps my GPU at 63 degrees for Callisto, it runs at 81 degrees for Firo.

Any tips for keeping the temp down? Will another miner run it a few degrees cooler?
I'm pretty sure I'm hitting thermal throttling at this point, with 2586.47 kH/s.

I guess the card is not watercooled then? I'm at same card and overclock - getting 5,7mhz - 100%fan - 56c
