120mm AIO Radiatior FAN Orientation

[ScubyUK]

Hi Techies, looking for some advice on radiator fan orientation.

 

ROG STRIX B550-E with Ryzen 3 3300X (will upgrade the processor in a year or so)

ROG STRIX RX5500 XT 8GB

6 x 2TB Sandisk x600 1TB with upto 16 more going in as and when space is needed.

2 x WD RED NAS 3TB (will be replaced with SSD over time)

 

Silverstone GD08B HTPC case Fans (front to back)

All fans are Be Quiet Pure Wings 2 PWM. 

 

Along the Front bottom of the case as intake

1 x 120mm and 3 x 80mm under the drive chassis

Right side as intake

2 x 120mm

Rear as exhaust

2 x 80mm

 

Silverstone says to allow a max of 138mm for the cooler rules out most Tower Air Coolers, the two TF coolers I did like sound of wouldn't provide much clearance once the lid is on which is why i'm opting for a 120mm AIO which will be mounted into the bottom of the 5 1/4" Optical Bay above the 120mm intake. That will obviously push air into the radiator, my question is do I mount a fan on top of the radiator pulling air through or should I mount it on top and push cool air down and have the warm air circulate around and out the top vent?.

 

Thanks!

Pushing or pulling through a radiator, as long as air is still going the same way, has a negligible effect on cooling. Go with whatever makes it easiest to install.
