Nespi case (Not the PLUS +) 2 Question

caver01

@shavecat I expect current draw would be your limiting factor with multiple fans, but I don’t know how quickly it becomes an issue. You could certainly use 5v and GND pins. I changed my fan over to a 3.3v pin to reduce the noise. A fast fan can get pretty loud. Why do you think you need so many fans?

@shavecat
I have read not to connect the fans directly to the gpio as this could damage the pi, instead you will want to use the fan controller as seen here

whether it is enough to power two fans, I do not know.

I agree with @caver01, you don't need multiple fans. A decent heatsink and case fan is all you need. Anything more than that is likely to make more noise and draw more power with no added benefit. My pi 3b+ is overclocked and heatsink/case fan is all I have ever needed.

Lovely okay thanks all :)
It was still around 60 even went to 70deg'.
At the end what i did beside put the heat stink inside and the double fans-
Did a small hole where the fan for the air outside was need to be and add big fan on it to get the warm air out -

now i get max 52 deg' most ,(after more then few hours gaming)
when i run kodi im getting less then 40-

i'd just switch to thr plus anyways. not for the safe rest/shutdown. But for the brtter voltage. Ive built some for friends and lept getting low voltage warnings on them all the time. didnt matter which cable i used. Switching to the plus version
, no more undervoltage warnings

@RetroSavior
i also getting the high voltage but really really not as many times as the start...
just once a well (Usually more when its really getting hot/warm) so im not sure its the plus helps....
check the temp' and if u really using the raspberry power adapter also helps.

@shavecat That is one cool pi (pun intended) Just keep your cat away from that fan, he might want to puke on it lol.

@shavecat If you think the Nespi case is nice. check out the MegaPi case from retroflag. Great little version of Sega genesis/megadrive. I like it a lot more as the design in it has better airflow with fan placement. Seems quiter too. And nice cable management and handy tray on top for extra micro sd cards. Just got mine yesterday and in love with it!

@RetroSavior
yes i agree think it is looks better but u know each one want it other box i think.
my case also have extra place of sd cards its really the same but different design.
Let my know if u do it with overclock and how is the temp when playing quake (on ports) or so ?
