MK3S+ Hotend Fan Upgrade Compatibility

I'm looking to upgrade the Hotend fan with this model

I know I will have to get longer M3 screws and change the fan header and wire length if needed. But I can't find data on the max power draw for the 5V fan header of the EINSY motherboard.

The stock fan is 5V 0.16A, for a draw of 0.8W. The above fan is 5V 0.32A for max draw of 1.6W. Is the EINSY fan header able to support this current/power draw?.

I'm also kind of assuming sensor cable/signal is universal. Any issues with the sensor wire?

Thank you in advance.

That fan (or more likely its mounting screws) is going to hit your left lead screw and cause the printer to not be able to home.  That's the reason the stock fan is 10mm thick.
