solarbirdI just got done modding my PSU to take an 80mm fan with a new housing - thus requiring feet elevation - because that PSU isn't amazingly well vented to begin with, and Ender's placement of it makes the situation much worse, like what-the-fuck-is-wrong-with-you worse.
That PSU is basically guaranteed to overheat and in bad, equipment-life-shortening/damaging ways, and it's Creality's fault.
A lot of complaints about Ender stuff, I can kind of toss away as cost decisions, differences of opinion, and so on, but this? This is very bad engineering, and I don't like it.
If you don't have the knowledge/experience to open up a PSU, I appreciate that and applaud your restraint, but you can remove the black outer housing without opening the actual PSU case itself, and that will do two things:
1. Roughly double the air-intake window for the fan, allowing more air to get in and,
2. Expose the actual air-outflow vents of the PSU, which are currently COMPLETELY CLOSED OFF BY CREALITY'S BAD CASE-MAKING DECISIONS.
That'll help. Won't make it any quieter, but it'll help with the overheating. It won't expose all the vents, but it'll expose most of them.
Might also print some foot-extenders too, that'll also help.
I don't think I realised how mad I was about this decision on their part until typing this up in a reply on r/3Dprinting. I mean, the OEM power supply unit venting isn't great engineering, they're brute-forcing it with that noisemachine of an intake fan, which moves an impressive amount of air for its size. I don't like it (because of the noise) but I can deal with it.
Creality throttling that off, however? For ... no super-clear reason I can even see? That's bad.
