Proform 67036 16” brushless cooling fan test.

128hz Off at 9% duty, on at 10% and full speed at 90%

This still go on a shroud for full coverage to replace a 16” flexalite flex wave fan on a 78 corvette with an LS swap.

Here is a breakdown of the data. This is not accurate CFM (rated at 3400 prob at zero pressure) but gives me an idea of air flow and speed through a core to compare my other fans. This fan would do slightly better on a shroud which would add about 100ft/min and 1mph more to air speed as thats what happened with another 16" brushed fan I tested.

10% = .25amps/3.3w and 196ft/min
20% = .5amps/7.6w and 413ft/min
50% = 3.97amps/52w and 964ft/min
70% = 10.68amps/137w and 1416ft/min
90% = 21.47amps/271.8w and 1849ft/min 22.1mph
