CR-10 V2 Silent Upgrade

My first upgrade to my new 3D printer is to make it super quiet.

The CR-10 V2 already comes with a super quiet stepper controller but the stock fan included are very loud so I replaced it with all Noctua fan.

Things that I used.

- Noctua NF-A6x25 FLX x2 - one for PSU and one for the casing
- Polulo stepdown regulator 24v to 12v. x2 - one for the casing and one for the extruder fan. The 24v PSU already using 12v so no need for the buck converter.
- M3x14mm screws x4 - for the new bottom cover
- M3x5mm screws x4 - for the fan duct mount.
- M3x12mm screws x4 - for the feet


Instruction:

- I printed the body and the fan duct with PLA/PET, no support.
- Printed the feet with TPU
- With this mod, we also don't need to put back the PSU cover since the new PSU fan is almost twice the thickness of the original. We also have better airflow and cover is just redundant.
