Question on fans and Pull Configuration on Radiators.

[amsga]

Hi All,

 

I am trying to understand better the concept for Pull configurations for radiators.

Usually I hear that for Push configurations, I should be looking at a fan with high static pressure to overcome the resistance from the radiator.

So looking at pull configurations, am I supposed to stick to the same high static pressure setup? Or am I supposed to look at a high CFM setup?

 

I am looking to build my first custom loop in 2023 with a O11 XL and am trying to figure out what kind of fans I need for top, side and bottom placements.

Thanks in advance.

high static pressure is best but at the end of the day any fan should do. i mean people spend way too much moeny and time trying to get it just right.  there use to be 3 types of fans but now there just 2 now.  with out so way of testing the fans the specs the box says is known to lie so...

 

for a really complex setup it most likely need to be an  engineer to build a setup for best air flow.

i typically use 1000rpm or 1250rpm charts these sites

i'm using 6x vento pro 120 pwm (aka nidec gentle typhoons 2150), it comes with daisy cable

Thanks. Was thinking if I needed to get something like 9 x NF-A12x25 or could I get away with the slightly cheaper NF-F12 for those radiators.

Thanks, I'll keep this as reference for my research.
