HoneyBadger Performance Series 5015 Blower Fans 2–4 Wire, PWM & Tach Options

Used these fans to replace the stock part cooling fans on the Qidi Q2 and Q2C. Not quite plug and play but I knew that going in to it. I had to flip some wires around when resoldering to the Qidi connectors. As far as the fans go, they made a huge difference over the stock ones. These are some really good fans, they are probably better than any stock fan out there. Do it and you won't regret it.

Works great. It is quite and pushes more air than the nidac fan I previously used

Powerful. Not very quiet. But just what i needed foe a project.
