    Some reason my CPU is idling right around 60 so the fan just keeps going on and off, and when it's on it's at a super low speed which is somehow even more annoying. Going to look at adding a heatsink and/or putting in a bigger fan then using this trick.

    If you were to purchase the Noctua NF-A4x10 24v fan and plug it in to the exact same spot the current 4010 fan is, would you still use this script "as written" or could/would you lower the target temp of 60 to something lower? (because of the much quieter Noctua fan). Or would you just leave the original printer.cfg file alone on the stock Sovol SV08 with the Noctua fan installed?

If your machine watches the two pins that detect the head is in place, then you can either drill out my housing to slip those two spring pins in, or you can short out the circuit because it is the brass of the head that shorts the two pins. You do this at your own risk, because lack of a head exposes high voltage.

      If you're not opposed to some cutting, print a nice fan cover (I liked thing:4288719) & cut the grill out of the bottom panel. I held the cover in place with the fan bolts run in from the bottom of the nutserts & hot-glued the new cover on (just by the corners to allow air in under the edges), then reinstalled everything. Drastically reduces backpressure so the stock fan never gets particularly loud and 50C usually stabilizes at about 30% speed. Non-reversible but doesn't require buying stuff. FYI it took me a few hours of shopping locally & online for cheap 40mm wire grills before it occurred to me "hey, I have a 3D printer now!" 🙄

Since the fan connection is only 2 pin, the PWM-ing is being done on the supply voltage to the fan and not the PWM control pin. Do you happen to know if fans with PWM control inputs don't do well with PWM-ed power?

Anyway, 24v 0.1A fans are super common: Replaced the 40mm stock one by a 80mm one (8010 meaning 80mm diameter, 10mm thickness. you do not want thicker than stock (4010) else it will not fit).

      Sorry, no. Too easy for someone to post online in a forum.

    I tried this a couple of years ago with half-inch irrigation tubing and a pond pump. The problem is, once the hot water circulates out of the system, the water doesn’t stay hot for long. Eventually the water runs cold and you’re just circulating cold water again. The only way this works is if the water in the black tubing is given just enough time to heat up, and then is circulated into the pool. Rinse and repeat.
