R9 280 H70 cooled?
So I picked up a cheap R9 280 and I have an old DWood bracket and an unused H70 that I would like to throw on it. It's not the best clocker (1170 / 1700 @ 1.3v) but it runs a bit hot. Gaming gets me into the 80's, peaking at about 84ish after an hour or so of running Valley Bench. So I'm thinking that I might be able to get 1200ish keeping it in the 60 range.
I'm familiar with water cooling, but I do not have any heat-sinks for the Vram chips on the PCB. The mosfets and vrms are factory heat-sinks however so I'm good there. Would I be good with just a 120mm fan blowing over the card, or should I look for a better solution?
