About 1mm clearance from rad to gpu, push cold air in, or exhaust hot air out?

[Defy Belief]

So, I’m doing a pretty niche build, more info will follow once it’s complete (not far off) but I’m working in a small case with 3 radiators.

Now on the 240 radiator, then 2 x 120 fans are directly on the panel of the case, so it goes |case|fans|rad|gpu.

So I can either;

A. Push in cold air from the outside, onto the rad, but the air has about 1 maybe 2mm clearance before touching the gpu. The top does have a vent so I guess the air would still naturally exhaust out of that?

B. Exhaust the hot air off the rad and out the case, this is how I have it currently as it’s installed (waiting on fittings to complete) with the air space in the fins, my logic is that this would be more efficient to just dump that air out of the panel of the case.

Thoughts?

240 cpu radiator will not emit much heat. The cold air from outside after going through radiator will still be cooler than inside air
So variant A is better.

Mmm, I'd got vaient B actualkly for me getting warm air out of the case is always no.1 personally, probably wouldn't see much difference between either possibly, but for me, I'd be going B, exhaust the hot air out asap.So my setup with 2x240mm and 1x360mm rads all with push configs pushing the air out of the case as for me, this setup generates that much heat the sooner it's out the less time it has to build up in the case... just my view though... suppose all depends on that particular user case.

Mate, from your disscription you could just test this yourself, is the fan outside the case? can it screw outside, that way you could just use push or pull and measure the differences? Maybe I'm not getting how you have it installed at the moment, my heads batterted today lol

The rad and fans are mounted to the case panel itself, so once the loop is fully built it will be very difficult to actually alter the orientation of the fans.

Thanks for your input though, I'm swaying towards B too.

Just to confirm, B is pulling out of the case and not pushing as I cannot mount the rad to the case and then fans, has to be fans then rad.

I would go with B, exhaust hot air out

Yeop I'd deffo go B and pull on that one straight out the case. Why blow cold air into a case, that then heats up the case, you'd want to pull all warm air out of the case and any grilled or holes will allow the air to come through. The only thing I'd say is, make sure you get a power fan for the pull because you need to pull through that rad AND pull air into the case so the most efficient fan you can get is what you need there mate! However, gonna be a sweet little case that and blimey yeah it's tight!
