This main controller board cooler aims to keep the original cover of the Anet A6 and provide efficient/directional cooling to stepper motor drivers and other hot components. The 50MM centrifugal fan is connected using a male to male 10CM cable. On the other side, it is connected to the 50MM part cooling fan's connector using tape. See my pictures. I finally reinserted the original connector back to the mainboard. The new fan simply piggy backs off of the other fan's connector. Again, see the pictures.

Please make sure to route cables away from the stepper motor drivers to ensure optimum cooling. In my case, the fan turns on when the part cooling fan turns on. That is usually after the first layer in PLA. If you prefer to have the fan run at all times, especially if you print using ABS, then connect the new centrifugal fan to the extruder fan connection instead.

This fan cooler is mounted on the top back screw of the Anet A6 main controller board using the original screw. It mounts in front of the main board and can pivot to provide different directional air flows as preferred by the user. Mine is configured to blow straight down.

I also have the A6, however my 50x15 fan always runs and my 40x40 fan is the one that is adjusted to cool at a specific layer. This seems to be opposite from your statement but I have my fans wired as the diagram shows. I'm just confused as to how ours differ. What version are you running on your A6? I am currently running "ANET V2.0"


My humble suggestion, simply reverse the cables then. The hot end fan should always run to ensure the filament doesn't melt in the upper part of the print head and causes you jams. According to the Anet diagram provide to me, the extruder fan should plug in to the FAN2 connection(on the outside). The part blower fan, should connect to the FAN1 connection (on the inside). I have board v1.0 and bought my printer over 6 months ago. But just reverse the 2 cables regardless of what is printed on the board or your instruction manual.

That's very interesting, I have mine wired as you say and was provided the same diagram as posted. I have had my printer for around 3 months and haven't had any problems with the way it is wired now, I just find it odd that the control factor seems to be switched between our main boards. Either way, thank you for the info! I may play around with switching the wires and will definitely be printing several of your designs/remixes in the near future!
