Description
A simple fan mount for 120x120x25mm or 140x140x25mm pc fans.
Don't use fans with a depth greater than 25mm! Thinner is fine!
You'll lose 10mm Z travel, but on the other hand you'll have much higher chamber temperatures.
Due to the high surface coverage of the bed and the even airflow, the bed shouldn’t warp too bad when using these.
5x M5x10 BHCS
5x Hammerhead nut
6x Fan screws
2x 120mm fans (max. 25mm depth)
Most fans run on 12V! Check your fan jumper (Octopus) before connecting the fan.
DON'T RUN THEM AT 100% SPEED!
These fans are overkill, but they are also really quiet when you run them at lower speeds.
I run mine (Silence Corsair fans) at 70% and barely reach 110°C (250³ Trident).
I also recommend changing cycle_time in the printer.cfg to 0.1
Just try what works fine for you.
