PLEASE READ THIS, its important! There are a few things i wish were added to this, to make it more clear, so i will add them so it helps others. 1) All the pictures uploaded, do not show where the fan wires specifically go to, in fact most pictures make it seem the wires go to the front control panel (with the knob)...well just so you know, they dont. They are supposed to go to the motherboard , but in the picture they don't appear to go there. 2) You can connect this without removing the motherboard its the plug marked on the bottom of the board named "fan ". Or if you want a more accurate name its the J20 plug on the Utimaker motherboard, if you want to google it. 3) This is a big one. Make sure the fans red wire goes to the + plug and the black wire goes to the negative plug. I know this sounds like common sense but my utimaker 2 plug was opposite what the plug was, so i was forced to cut the fan wires and reverse them. If this is wrong all you will do is cook your fan.(glad i bought 2 because i cooked my first fan) 4) when you power up the utimaker this fan should come on and stay on at all times. So test that it working before fulling installing it...If its not turning on right away something is wrong shut it down right away and check #3 closely. You may have to remove your board because the + and neg are marked on the TOP of the board. Good luck i went through pain figuring this all out .. i hope you read this and check ahead of time.

Thanks. Is there any chance you have a STEP file for the blower fan? Just curious.

J20 is always on, from what I remember the only pwm's are for the cooling fans and hot end. There may be a method of turning j20 on/off but I haven't looked into it any further, I can't hear the fan at all.

So, does the fan run all the time or is there some G-Code needed to turn it on and off?

Thanks again, that's exact what i'm looking for. I have applied heatsinks already, but i want a litlle bit extra cooling. Fan ordered. Marcus

Blame auto-correct for any goofy looking typo's in that last response, LOL.

No problem. The fan doesn't add any noise at all from what I could tell, I sat infront of it for an hour during a print with no increase in noise. It may not be pushing as much air as a louder higher rpm fan might, but it's certainly better than what cooling the bird comes with. I started noticing browning around the solders for the xyz drive connections indicating some overheating. So is like anything that can help keep temps down during long prints. Enjoy :) - Erick

Thanks a lot! With your description i've found the cooler on the german amazon and ebay site. Is the fan noisy?

Here you go, this is the fan I'm using: 2 Pin Connector Brushless DC 24V 0.15A Turbo Blower Cooling Fan https://www.amazon.com/dp/B00H8VV0XK/ref=cm_sw_r_awd_c6pewb0NJCRBJ - Erick

Hello, do you have a link for the fan? I only find fans in the right size for 12v or 5v. Regards Marcus
