40MM Overclocking Fan Shoot Out: Airflow, XFan, Delta, AVC,

What 40mm fan can withstand overvolting? And why would anyone do this to a 40mm fan? Overvolting makes the fan move faster, driving more airflow, but at a cost. As noted on Anandtech, “You can double the voltage but you won’t get double the RPM. You will see get 4x the power consumption though (P=V*V/R). So if you are overclocking your PC, and decide that overvolting your fans might be a good thing to do, it might be best to use different fans instead. Or else the following sparkup and flameout might result.

What is this video?

An amateur 40MM fan shoot out featuring a random set of commonly used 40mm fans, found in PC’s and Servers. Manufacturers include: Airflow, XFan, Delta, AVC, and more.

What is the objective?

Work to see upper voltage limit of common 40mm fans.

What is the test methodology?

– gradually increase voltage till all fans spark up and fail, (and in some cases catch on fire).  This is not recommended by these manufacturers.
