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
