Please tell me if i've gone insane, or if what I'm saying makes some sense at all. Am I just completely wrong, meaning that fans can spin so that air exhausts from convex side? Or is it really the case that EVGA gpus may push air down? Some people said that fans can spin either way, but it just seems like pushing air out from convex side would be really inefficient.ĮVGA 1070 SC ACX 3.0: (this looks concave to me) MSI 1070 Gaming X: (this looks convex to me) When looking at the fan so that the circular sticker with the Noctua logo is facing you, the direction of airflow is towards you and the sense of rotation is clockwise. According to the explanation above, it seems like EVGA gpus would push air down (away from heatsink) when installed while other ones such as MSI 1070 Gaming X would push air up (toward heatsink). This downward airflow direction creates a light cooling. (If this is wrong, please correct me.) With this in mind, as I was researching which gpus to get, I noticed that EVGA gpus have fan blade curvature different than other gpu brands. When set to the counterclockwise direction in the summer, the ceiling fan pushes the air downward. Usually, the fan is mounted on the front side of the. Reversing your fan, to a clockwise direction, creates a gentle updraft, recirculating heat down. There is a small arrow on the frame of the fan that will show you what direction the airflow will be going.
Generally, the direction should be set in a way so you can draw in the. I noticed that there were only two fans installed on my computer - a CPU Fan installed at the back of the casing with a duct heading towards the heat sink (no fan on top of the heat sink) and the other is the exhaust fan of my PSU - all are exhaust, meaning. The combined fan airflow versus pressure curve for multiple fans operated in parallel is identical to the single fan graph, with the only change being the values of airflow are multiplied by the number of fans operated in parallel. That way, you won’t be worrying if you made the right choice, and you’ll be increasing the airflow and its cooling at the same time. The proper CPU cooler fan direction depends entirely on what kind of airflow you want. This is all about my old Dell Dimension 4400s design. The airflow directly underneath the ceiling fan should push down, creating a wind-chill effect, which is going to make you feel cool. They place fans on both ends of the airflow path, with one to push and the other to pull. Other than actually testing the fan or looking for arrows, it seems like concavity/shape of the blades are good indicators of which side is exhaust and intake - concave side is exhaust and convex side is intake. During the summer, use your ceiling fan in the counterclockwise direction. So I've been looking at how fans work and which direction it blows, etc.
