Right now, with the Duet upgrade, the only thing making a lot of noise is the 40mm fan of the Titan Aero. So I was considering a water-cooled version, but I googled it and found nothing. Making one myself is out of the question as I don't have access to a proper cnc mill. So... has this already been discussed? If someone is willing to make one, I will buy it for sure. Any ideas?
