A buck converter can be used to provide 12v to a 12v fan, even if your power supply is 24v. It can also be used to under-volt LED lights to run them cooler and make them last longer.
This tray can be attached with either zip ties or screws. If mounting with screws, use two M3 x 12 mm. No nuts needed. I drilled two holes in the left side of Ryan’s Jackpot enclosure using a 7/64" drill bit. I pre-marked the hole locations with a Sharpie, at about 14mm down from the top edge, and using the spacing of the top corners of the printed tray, since those corners are the same distance apart as the holes themselves. Below I illustrate these corners, but I marked and drilled from the outside of course.
I do run a 24V fan, but I think I run 12V to a WLED controller I built for the underbeam workpiece LED lights. (I have to get it down to 5V for the controller, but the lights are 12V.) I run a bigger power supply, then convert it to pull what I need.
I’m not sure the hole spacing is standardized, so I think this is a great idea, but I’ll probably need to remix it for my specific convertor.
I had in fact already bought two 24V fans so that I could have one for both my small LR4 and full-size LR4 machines. However a 24V fan is orders of magnitude louder than the 12V whisper quiet Noctua fan I have been using on my V3. I’ve been undervolting the 24V fan on the small LowRider v4, but it’s still very loud in an ear piercing kind of way. I couldn’t undervolt it any lower because I was also running LED lights undervolted on the same buck converter, and if I turned that buck converter down anymore, it took the brightness of my lights down to very dim or even completely off.
The LED lights themselves are made for 24 V, but were too bright and too hot for my taste. They were intended /sold as 24 but I’m running them about 21 or 22 V I think.
I put this fan on my Beta and it is not super loud at all. Can barely hear it with nothing running. And you really can’t hear it when you are making a cut
I get not wanting an annoying sounding fan. I am bad for turning my machine on the first time I use it when I get home, and not turning it back off until I leave for work 2 weeks later. So I wouldn’t want it running a super annoying sounding fan for that length of time.
The 5015 fans that Ryan suggest are quiet as well as the one I posted if you want another option. I am putting the 5015’s on my prebuilts. I want them to go out how Ryan intended them. Less worry when it’s time to troubleshoot anything.
Sometimes my Lowrider is switched on while I’m videoing (showing something regarding what I’m doing), and sometimes it’s switched on with the router off, between jobs, while I’m going back-and-forth from the laptop to the machine. During those times, it either ruins the audio of a video recording or just simply is very very annoying.
Same for sure. Fans are running in mine now. But @DougJoseph is lucky enough to have an air-conditioned space for his LR. so I am sure its not near as noisey.
I will try to get a video. Its not silent. But if they think that is loud they must be in a silent room. The 5015 is a little quieter though, and you can get those from Ryan.
