Replacement fan ordered. It's a 30mm fan (yeah, really!) with no speed control and driving me nuts whenever the power is on. Was looking up what sort of cfm a 30mm fan pushes just so I wasn't downgrading it and stumbled upon a seller who described (honestly, to be fair) it as
...and that's exactly why I want to change it! A nice Noctua at 60mm will fit and push about twice the cfm....but quietly. I think it would technically fit inside the existing case but I'm planning to mount it externally just for some extra space. Might have to print a TPU gasket to seal it. Don't they sell those? Yeah but at over a tenner, I'm printing my own! Might have to print a finger guard too as the chances of having a 60mm in stock are slim....and I'm not ordering one either!
Reason for taking it apart in the first place was actually to see if I can tap into the Z axis limit switch. I've got the touch probe (temporarily) wired as well as the tool setter. Those are all on the probe input. The tool setter also has an over-travel switch (basically to stop it crashing if it doesn't register) and the easiest thing to do with that is hijack the Z axis limit switch. Tell a lie the easiest thing would be to cut off the extra wires and ignore it....but that's not happening!
Was also wondering if I could run a mains relay off the 48V output to the spindle. Would let it turn the router on/off but only give me manual speed control - which is a step better than the current situation where I'm bound to eventually start a cut without the router turned on! *P'TWANG*

I fitted tiny Noctua on my 3D printer they are amazingly quiet, I even stacked a couple on the heatsink to ramp up the pressure and still quiet as hell. Some 40mm I think so slightly larger on the main board. Highly recommended!Replacement fan ordered. It's a 30mm fan (yeah, really!) with no speed control and driving me nuts whenever the power is on.

Definitely. Ran a couple of 40mm Noctua's on my first 3D printer. Hotend was quiet but layer fan wasn't so I ran PETG and left it off 99% of the time. Not Noctua's fault, a weird implementation of PWM by Creality so they chopped the ground in very course divisions and it made it sound awful. This one I've got more space and weight isn't the issue it was on a hotend so I can go up to the dizzying heights of a 60mm fan Just designing the gasket for it now...obviously before I have the fan in my hands to measure!
Mind you, harping back to 3D printers, I've just realised I'm back in the same boat there. I could use the CNC to cut a nice circular hole and screw holes in the case...but the case holds the controller so the CNC doesn't currently work. Its 3D printer control board upgrades all over again! *facepalm* Might be time to get the adjustable hole cutter out for the manual mill. Why don't I use it often? 'cos it's damn scary, that's why! More so as the size goes up and on thin stuff. So yeah, if this thread goes quiet, you know what happened!
