Hello, have a lial li pco11 xl with three 360mm radiators. Currently I have all ( top, bottom, side) set as intakes. There is a single 120mm exhaust. I know this is massive positive pressure but I thought theoretically having all intake would cool the water best. I can't decide whether to change my top rad fans to exhaust. The downside I have noticed with all as intake is that it heat soaks the entire case where it is warm to the touch so it may be adding heat to the radiators.
What do you think top intake or exhaust, thanks.

Top fans mounted as exhaust in pic from my original setup.

Exactly.....I see these rigs with fans everywhere....major overkill....they dont seem to understand gpu under some load is meant to get warm unless you have a open air setup...5 fans is more then enough....

Sure they are…. Warm means throttling which means lower performance. Thanks but I’ll keep my stuff cool

Lol....ok dude....u put those fans everywhere and while ur at...dont forget to put one near your piehole...there is alot of hot air coming from there....suggest you read a physics book if u ever have the chance...when ur not to busy buying more fans....unless your dipping ur gpu in some kind of cooling liquid or gas....ur box full of fans aint gonna cut it....

Sure whatever you say buddy. You stick with your 5 fans and turning off your GPU, I’ll be here keeping mine cool.
The cooling liquid is called water

The top 3 fans are already facing exhaust.

He's right! Great catch.

I think this is one of those times where I question how useful your side radiator is. I assume it's not a very thick rad in order for it to fit between the top and bottom? I wonder what it would be like if you had the side without a rad (just fans) as intake, bottom intake, and top exhaust. The GPU will cause some turbulence from the bottom air, so the side intake should supply good fresh air to the top exhaust rad. The rear exhaust would do a good job of grabbing that warm intake air coming from the bottom rad.

The side radiator is good still a 55mm. I changed my top fans to exhaust and I think it is all around better. Case is no longer hot to the touch and looks to be lower temps.
