I'm looking at the Hardware Labs GTS X-Flow rads specifically because they seem to offer optimum cooling when used with low rpm rans, I'm trying to keep it as quiet as possible.
The non-XFlow GTS are actually better performing than the XFlow. The flow restriction is worse in the non-XFlow, but this shouldn't matter unless you have a useless pump or a very complex loop. The regular GTS is actually one of the best performing rads when it comes to low RPM fan speeds.
I currently have a Nepton 240M up front in my W2, which is 52mm including fans. There is an approx 20mm gap before the GTX 1080, so I don't think you'd want much thicker than a 30mm slim rad in there, but in theory you could get up to 40mm but that might look crammed in and wouldn't necessarily offer better performance anyway. The GTS would fit perfectly and is ideal for lower fan speeds.
A 280 rad I thought would be OK up front given that the case comes with x2 140mm fans there anyway, the only issue is height. but I think it would be OK. That said, the Hardware Labs rads apparently do come in a bit wider than most other brands, so this could be a potential issue and would have to be checked.Edited by atomicus - 7/27/16 at 3:21am
