I moved into a new case and had room for a 280mm so I decided to see how the H115i did. Press question mark to learn the rest of the keyboard shortcuts. Push. This works whether the fan is a pusher or puller. Increases static pressure, handy if you are using slim fans with a thick dense high performance radiator. XT45 will provide 50 watts of cooling in push, 60 in push pull at 1000 rpm UT60 = 50/ 61 Monsta 80= 51 / 62 For each 120mm of radiator: XT45 will provide 61 watts of cooling in push, 74 in push pull at 1250 rpm UT60 = 63 / 76 Monsta 80 = 60 / 80 For each 120mm of radiator: XT45 will provide 68 watts of cooling in push, 82 in push pull at 1400 rpm Ascend to... the PC Master Race.

I have always used internal radiators with both a push and pull setup since 2000. Good saying: when in doubt push out. Engineers apply the knowledge of math & science to design and manufacture maintainable systems used to solve specific problems. You can try to do exact calculations on the different heat rejections between the 2 orientations, but from the industry point of view, it will be negligible enough to justify changing the standard pull orientation. "Push" vs "Pull", radiator airflow configurations. Press J to jump to the feed. Using radiator as intake on the other hand hardly effects GPU temps in game. Another factor could be the fan speed. Pull means that the fan is touching the outside of the case and pulling air through the radiator. Push means that the fan is closer to the inside of the case and pushes air though the radiator. Menu.
