Anycubic i3 Mega 80mm Motherboard Fan Adapter

thingiverse

Been on a mission to quiet down the i3 Mega while increasing air flow. Stock motherboard fan is 50x50x10, is stupid loud and offers minimal cooling. This adapter zip ties to the bottom cover/grill and accommodates an 80mm fan. I used a [Noctua Redux fan](https://amzn.to/2U2XrOm) and it works awesome. It's nearly silent and pushes a ton of air. Yes, it's 25mm thick but fits and blows great. It's also a 4 pin but can be adapted to be a 2 pin using the stock connector. Match black to black and red to yellow (on the fan). You could also use the [Cooler Master 80mm Silent Fan](https://amzn.to/2CgGZTN) which is only 15mm thick, blows 24CFM and is comparable in db rating at 20db. I can't vouch for how quiet it is since I haven't tried it but the specs look good. Any 80mm fan would work with this adapter. A slimmer fan would give you even more clearance but I can attest that the 80mm Noctua is nearly silent.
