Push or pull?

Hey guys,

Quick q, for my AIO cooler, I am putting it in the front of my case and wondering for airflow if I'm better with a push or full configure?

I've always read that Pull is better, and your instruction book will probably say to set it as Pull too. I think LinusTechTips did a video testing various fan configs and I think the results were negligible. Best to check the video out on Youtube. The theory however is that you want cool air passing through the radiator and the cooler air is outside of the case.

With most fan it makes little to no difference in actual airflow. But pull tends to be louder, mostly due to how close fan blades are to mounting surface. The structural frame on exhaust side of fan that fan motor is mounted on means fan is spaced cc 5 mm from face of housing .. on intake side the fan is almost flush with face of housing. That few mm often cause harmonic noise to be generated byfan blade moving closer to mounting surface. Almost all fans are quieter with 10-15mm space between fan and mounting surface.

There are a few fans that the blade design does make a performance difference, but very few.
