I got this last time, great kit but the fan is obnoxiously loud. You'll want to invest another couple of dollars on a better fan

It goes for the same price every now and then. I got 2 different sets, one of them has a loud fan, I disconnected it. Another set had a more quiet fan, I am still using it.

correct, fan is VERY loud. Also, first case I received with the bundle caused the board to restart, probably something wrong with the geometry of it or something. Replacement one (same case) worked fine.

Had a look on Amazon, so many to choose from. Any suggestions on a quite fan to upgrade to and still fit in the Labists case?

Its never recommended but..
trying running fan off the 3.3v if its a 5v fan. that will quiet it down. most would recommend a diode tho to drop the voltage to be safer vs right off the 3.3v pin. But that choice is yours. Just something you could google to learn more about so your advised of potential problems to your rpi. I use the flirc case myself.

Or consider seeing/inquiring if its already a 3.3/5v fan that was included.

There is absolutely nothing wrong with that. It is just a simple DC motor and can work at varying voltages. Going above the rated voltage (5V in this case) however may cause the fan to burn out, due to the heat, melting the insulation of the winding inside and causing a short.

actually drawing too much power tends to cause the same burn out but in other places. For example the same logic behind using too little amps vs too much amps. Too little amps when the device requires more over works the power supply = burn up and smoke.

the 2 common concerns were for this scenario were. that the rotating voltage would back feed unrated voltage to the pin at shutdown but thats not a concern on brushless. 2) drawing 5v on a 3.3v line may overheat the pin at bootup where the fan is "still" and peak voltage is drawn to start spinning.

I have been doing this for over 20 years now. You talk from theory, I from experience. Even 12v fans can be run on 5v or even lower

PS: Peak draw on a fan, is not going to be at startup.
