Water Cooling Radiator Fan Placement

Static pressure fans are designed to pull or push air with extra force which is ideal for areas with more restricted airflow like a water cooling radiator or a large cpu cooler with lots of fins.

Water cooling radiator fan placement.

Water cooling systems. All fans will be configured to 100 in our testing. We continue our guides that show differences in radiator performance depending on the speed of the fans thickness and fpi of radiators etc. An unshrouded fan is moving air through only the portion of the radiator equal to the surface area of the fan.

It s a little hard to see but there is a radiator behind the two front fans and this is the system with a top mounted radiator. Fans move air through the radiator assisting in cooling the engine. In the very least we can look at liquid cooler placement performance in a few different cases. With the fans mounted below the radiator you will want to use the 8x 10mm screws the shorter set of screws to secure the radiator to the case.

The fan blades of high static pressure fans are more curved and are directed towards the heat source. But consider this at idle or cruising speeds you need the entire cooling system working at its optimum. This includes measuring how much a front radiator might reduce cpu temperatures at risk of raising gpu temperatures or how a top mount might do the opposite. Today we address the subject of push pull push pull fan setups and how they affect different radiators and performance.

A fan without a shroud is better than no fan. Also there is a lesser gap between the adjacent. One thing i did differently to the other tests i have seen is not locking any fan speeds in the system so the gpu radiator case fans were set to the default quiet curves. Placement of the fans.

You have the reservoir the pump the radiator the fans some tubing a block for either the cpu gpu or both and the water itself. That said some basic tests on these high static pressure models show that their benefit is questionable in standard air cooled builds. If you mount the radiator with the fans on the bottom then it might be easiest to mount the fans to the radiator before installing the radiator into the case which is what i did for this installation.
