@korn16ftl3 said in linux novice needing a bit of help:

my question is how or where do i make the changes in the config.txt to enable PWM on the required pins from the guide i am trying to follow?

Just add a line at the end of the existing config.txt with the required dtoverlay option. Lines beginning with # are just comments and will be ignored by the Pi bootloader.

No idea... ordered some 3M. No use pulling the sinks off now until I have something to reattach them with. :D

Whom did you answer with this? Just curious, because my question right before was meant for @jamrom2. 😉

@zerojay Thanks. Good to know.

It’s worked excellent for me. A little loud but other than that it’s really cooled my pi off.

@ortsac said in PS3 Cooling Fans:

@ecks What other devices and controllers do you use the USB? What is power rating on the fan that you will be using? Does it have any labels on it?

There is no label saying anything about the power rating on it which you can see in the images and like i said USB wise for cords i use it for my game controller and phone to recharge the only thing i have left if an old micro usb charger but it is not even 5 volts it is more like 2 or 3 volts instead (was made for a super old flip phone)

necrobumping my own post because I found a workaround.
I use runcommand-onstart.sh script (docs : https://github.com/RetroPie/RetroPie-Setup/wiki/Runcommand , my script : https://pastebin.com/XunR2bBY) combined with some delay (hard programmed in my fanControl program) to relaunch fanControl after Mupen has done its shenanigans and thus reclaim the GPIO.

@Wizardling I can't speak to the general design choice for an outward blowing fan in most consumer electronics blow outward. This won't prevent dust accumulation because what goes out must come in somewhere else. This is usually remedied with air filters of some kind.

I use an inward blower and it seems to be working great. My Pi3 generally runs about 20 degrees cooler with the fan. I also use a heatsink applied with arctic silver thermal adhesive so the cooling is quite efficient. I'm not concerned about dust buildup because I just use it for gaming sessions that last no more than a couple hours once or twice a week so I imagine to get enough dust buildup to cause a problem will take years.
