Hotend fan for Anycubic I3 Mega

I bought an E3D v6 and connected it to my Anycubic I3 Mega. During the configuration it turned out that the fan does not start automatically if the temperature exceeds 45 degrees Celsius. Measurement to the fan shows that the fan does not request 0.1 Amps but 0.15 Amps. The original fan asks for 0.07 Amps, which is about half. I think the 0.15 Amps is just too much to run, is this a fan of 'less' quality or are all fans of E3D asking that much? Has anyone also 'bothered' and found a solution for this. The supplier indicates that he cannot mean anything :-(.

Answer this question I have this problem too

Is this a good question?

Hi T.F,

We recommend wiring the fan so that it is set to always on.

Hi Dan, thanks for your reply. I don’t know how to set the fan in always on for this I3 Mega. And I’ve just measured the voltage on the fan when running on high speed. The voltage is, in my opinion, to low because I measure 9V instead of 12V. On the original fan is the voltage also 9V, but it uses less current.

Wiring the heatsink power fan directly to the power supply/ power rail on the mainboard enables it to run as always on. Make sure you have the correct voltage fan for the power supply you are using.
