Rad/fan setup

[Protomesh]

what if you had a single 120mm rad as rear intake in push/pull, then had 3 front fans exhausting (negative pressure) would it significantly increase the efficiency of the 120mm rad?

 

Or would you just be better off using the rear rad as exhaust anyway...?

 

Ignore dust in this scenario. And yes I know it would be better to just use a 360mm radiator up front, but in this scenario what if you just had a spare 120mm at hand.

It'll just be like any other 120mm rad if it basically was open air ish. Still kinda shit for anything mid range cpu's.

3 intakes would push more air THRU thecase than a single would.  3 exhaust pull air from a limited area well, but don't provide the airlfow needed.

Front exhaust would basically have no impact on the performance of the rear rad, and not much on the inside temp

You'd be better with a basic aircooler, 3 front intake 1 rear exhaust

Hi buddy,

 

I think I'm with you on this as my philosophy when it comes to water cooling is, 'if it fits, then whack it in'. I have 2 builds that have 120 rads on the rear exhaust fan mounts AND have them as push pull intake. See photo of my Hyte Y60 build. I've got all of my fans in a weird config dur to the case being in an enclosed space so exhausting into that space would be counter productive.

push pull dose not off much preforamce if any... atlest for the added cost of the fan.

if the gpu is not water cooled then you want the back fan as exhaust

If you must use the 120, mount it on intake in front with 2 fans, and put the other fan on the rear on exhaust.
