I think the 1080 runs cooler than the R290. The R290 is a hot card!
Also the Air 240 is a very small case man. Can't fit much inside there. Not sure what else you can do besides external radiator...
2nd rad is what i plan to do - Top of casing, it got already a nice roof cut-out.
then do a square arcylic to increase the height and cover the rad/fan.
prolly go for slim rad so the total height will be lower.
I'm just not sure on how to plan the flow.
Current flow : Pump--->CPU--->GPU--->Rad--->Res.
Pump--->CPU--->1st rad--->GPU--->2nd Rad--->Res (BTM TO TOP).
Pump-->GPU--->Top rad--->CPU--->Front rad--->RES. (Top to Btm)
