Need some help with deciding which radiator size to pick for my project.

Hey guys,

I'm currently in the process of laying out hardware for my case design.

I've come to a point where I'm not sure which radiator to pick as this also affects the overall footprint of this m-ITX case design.

The loop itself is supposed to have a 1080 ti FE with EK waterblock and i7-8700k with an EK motherboard monoblock.

I'm not really going for 24/7 OC on these and I plan on undervolting CPU, delidding etc. to have low temps.

I can either pick an EK SE 240 rad which is 280 x 120 x 28mm (L x W x H)
OR an EK SE 280 rad which is 320 x 140 x 28mm (L x W x H)

So the footprint will be 280x120 or 320x140.

Of course I prefer the smaller footprint, but bigger rad will keep the loop cooler and 140 fans will get some more air going inside the case itself.

I've never did a small build, do you think 320x140 is big for m-ITX case? Are these ' 40x20mm ' extra worth the lower temps?

Or is the 280x120 mm neatly small and 240 rad will do just fine?

Considering I'm not really going to OC it I think 240 will be just fine but I'm not so sure..

So what you think guys?

Cheers

If it fits, it sits. Would the case itself be smaller with a smaller radiator choice?

Yes. Height stays the same but length and width changes according to the radiator size.

Well if you only need the smaller one then no sense in making a bigger case.
