Push/Pull or add a shroud?

post #1 of 21
Thread Starter 
i am running a swiftech 3x120 rad with scythe 110 cfm fans in push right now. Would i benefit more from going push/pull or by adding a shroud to get the fans away from teh rad a bit and eliminating the dead zone from the motors?

also, i havnt found many 3x120 shrouds around. where can i get one for a decently low price?

Maybe another alternative would be some Phobya 120mm Plexi Shrouds? They add about 20mm's between the rad and fan to help eliminate the dead space behind the motor...

Shrouds give little to no gain. I say just go push and push/pull if you are really hurting because its too quiet.

really? there is so much rad area that is not utilized due to the fan motors causing dead zones in airflow. Im not hurting but im looking to add a 2nd 580 to my loop and i just want to optimize what i have since i cant fit more rads.

Watercooling isn't pushing the pressures that it does where a shroud helps like in an automotive application. You can see the results in Martins recent tests. Push is 1c better than pull, and push/pull is 1c better than push on average.

FOund it.

You could just go balls to the wall and get three more fans AND the plexi shrouds... thumbsupsmiley.png

Why, it would be a total waste?

I'm not exactly following that graph... maybe I just haven't had enough coffee or something...

Why don't you just add another radiator.. say a 240 radiator...?
A single 320 radiator will suffice, but temps won't be as you'd hope.....
Go push pull, so you know your radiator is being used to it's fullest..or add another radiator and put the same fans.. or upgrade rads all together...
Either way.. add stuff to the loop, regardless if it's low TDP or what ever will add heat...
GLHF!!

The graphs show zero to negative gain on the shrouds and adding shrouds to push/pull is mind blowingly wasteful real estate wise.
