Hi, the fan in my pi-top 4 died and I’m searching for a replacement. I have searched and even though there was somewhere a mention of a partnumber, I am not able to actually find that. As it seems to be a 30x30x7 3 pins fan, finding something similar is pushing me in the dark corners of AliExpress but can’t seem to find a proper fan that has the right connector and such.
I’ve found two topics on the forum from a few years ago, but they either got a tip about using some oil or where it was picked up by support, so those aren’t helpful to me right now 
The tech-spec simply states; Integrated 0.9 Watt centrifugal cooling fan (30 x 30 x 7 mm)
Is someone able to guide me to a proper fan replacement? Many thanks in advance!
As I’m only allowed one picture right now, I tried to pick the most explanatory one
Welcome @SnakeMind!
Not sure whether this will suit as the power profile is about two thirds of the stated 0.9W spec but how about https://www.digikey.co.uk/en/products/detail/sunon-fans/4127-MF30060V1-1000U-A99/9838567 ?
Thanks! And yeah, I’ve found some other 2pin fans that would come close, but that would end the fancontrol functionality I think. It’s very hard to find fans that are 30x30x7 with 3 pins like the original one (and also the right connector!)
This is the connector it has, and as I don’t think I could replace that easily it would be useful to have a fan that has the same connection
Ah. Yeah I failed to note the two wire cable instead of three…
Alright, @pi-topJorge @RezIN @angus could really do with your help here!
It can’t even be the 30x30 fan component as used by RPi here because the fan thickness is pretty much 10mm so presumably too thick for this application
