Fan Mod for Filament Dryer Creality Space Pi

[T_guttata]

Hi

Recently I have bought a Creality Space Pi Filament dryer. The fan annoyed me such, that I decided to do a mod.

I have searched for a replacement fan, but I could not find any from a well known brand. The original fan looks like that:



Since I could not find any 1:1 replacement, I bought a Noctua 60x60 fan (NF-A6x25 FLX) and made a new air duct:



This worked fine and the device is much more quiet now. But: since the airflow is way lower, this resulted in much higher temperatures during the heat up phase (I measured 130°C). As a result, some of the plastics melted:



--> The safety of the device is somehow questionable. I mean, a failed fan should not result in melted plastics?

Anyway; since I don't intend to run the device over night with the Noctua fan, I'm again searching for a 1:1 replacement of the fan. Any ideas where I can find a high quality fan?

Those fans while quiet don’t make good static pressure.  You could try stacking another 60x60 fan and retest, but without knowing what the stock fan was providing for flow and pressure across the heating element it’s hard to judge.

those mini blower fans can go to hell. I got around it before by opening up the chassis a bit till I got good air flow on a zippo lighter with a normal fan


but for a dryer IDK

those fans are like pumps that push air through high pressure drop things. But they sound intolerable. You need to remove air flow obstructions.

What is the purpose of that grate?

Because you need to look at it from the standpoint of a plastics manufacturer:
1) do the vents really need to be like that or is it because its easier to make in a mold? Perhaps otherwise it would need to be made out of better plastic.
2) do the vents really need to be like that or is it because it would require reinforcement of some kind (structural)
3) did anyone even think about why those vents are there or is it because they wanted it to look cool (chassis are a MASSIVE marketing hype). I had this product I used to work on with a trendy chassis and it made any redesign a fucking nightmare. the 'industrial' version, they put the same shit in a normal box and it worked the same and passed EMC no problem and you can add stuff. awful design work on that. The "appealing" one leaked so much EMC and had such dodgy thermal behavior and cable routing you wanted to tear your hair out even if you had to open it. It was a flimsy mitered metal clam shell thingy. fuck it.
4) does it need to be a small amount of odd holes or maybe a mesh would work, but again thats a extra part you need to screw on. unacceptable for bottom line
5) crazy intake ducts like a engine. for high performance engineered air flow the future is NOW people 


be skeptical . It is designed with ALOT of work to make it look a certain way, but it often leads to insane shit, like blower fans that run 24/7... their often not more clever then you, apart from the fact people might click it easier if it looks like some space office shit.


my guess: their going for the high tech 'book' look at bottom dollar. expect nonsense
