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?
