How much radiator am I going to need to comfortably cool all of these. gpu's are not super overclocked.

[airdeano]

depending on overclocking, no overclocking voltages a single 280x60 can do the whole lot.

raising the voltages, then 1x 360x60 and 1x 240x60 will cover that combination with the most wicked voltage overclocking (1.5CPU/1.4GPU) and allow low speed fans to keep it all quite.

what about slim rads?

[airdeano]

personally, not efficient enough for low speed fans. to offset the thermal deficit, they have to use a tight fin array; which needs drastic static pressure or 2000rpm+ fans to make the cooling comfortable. could think about 45mm thick radiators, but you'll see to jack the fan speeds higher for 100% loaded situations.

EKWb have 280mm rad, that have like 2x more volume than slim 240mm rad.

And it's only 1,5cm thicker.

 

I also wanted to order slim kit from ekwb, but decided to get a bit more money and go for 280mm performance version. Mostly because D5 pump which should be quiet. Right?
