I’ve got this RPi 4 model B that I haven’t been using that much since I bought it some months ago. A couple of days ago, I pulled it out from the drawer and installed Raspberry OS (64-bit) on it. I am planning to do an EnOS ARM installation soon and perhaps try out other distributions as well. I j…

[image] pebcak: The CPU runs at 2000 Mhz and the temp is somewhere between 55-60 Celsius. <a href="https://www.amazon.com/Noctua-NF-A4x20-5V-PWM-Premium-Quality/dp/B071FNHVXN/ref=sr_1_2_sspa?dchild=1&keywords=noctua+40mm+fan+5v&qid=1608641295&sr=8-2-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUEySEdLRUI4M1lFVVc4JmVuY3J5cHRlZElkPUEwMjM4OTg0MzRONlg4SFhDU1MzTiZlbmNyeXB0ZWRBZElkPUEwNDE5NTU1REtIMVZUUThMV1hIJndpZGdldE5hbWU9c3BfYXRmJmFjdGlvbj1jbGlja1JlZGlyZWN0JmRvTm90TG9nQ2xpY2s9dHJ1ZQ==">Add this little fan to your current heatsink / case and you will drop your temps by about 15 degrees C.

Thanks for your input @Pudge ! I appreciate it. The Noctuna fan looks good! I guess I need to do some accessory shopping for my Pi. I have had a look at at the documentation for the config.txt here: [image] Raspberry Pi Documentation - The config.txt file The official documentation fo…

[image] pebcak: Does this means that the Pi could rather “safely” come up to temperatures right below 85. Supposedly, that statement is correct. However, I think you would start to get CPU throttling well before that happens. So even if that temp doesn’t fry your SOC it could result in decr…

You are certainly right in everything you said. I get it totally. I was rather “theoretically” curious about the relation between the temperature, performance and of course the lifespan of the device and how one could play with those variables to find a reasonable “middle-ground”. [image] Pudge…

[image] pebcak: [image] Pudge: IMHO if a $14 USD fan can get my general usage temperature under 30 degrees C, which is half of temp_limit=70 or 75, I would consider it a worthwhile expense just to try and get the most life span out of it as possible. So true! I will surely look into it du…

I just did a stress test on my new EnOS-ARM-GNOME installed just yesterday. I haven’t got around to order a fan for the device yet so this is with passive cooling (Pimoroni heatsink) and the default /boot/config.txt: [Screenshot from 2022-02-09 21-20-51] The temp went gradually up to 62-63 C and …

So here I am with the report from some more fiddling and testing. By chance I went by a “brick and mortar” computer shop and picked up ▶ this tiny little fan It looked quite frail but I was curios to see how it performs. It was also very cheap so not a hard decision to make. Anyways, I have been wa…

Thanks for sharing your experience and experiments and for going into so much detail. I’ll try to replicate this during the weekend and give feedback on temperatures with overclocking at the levels you suggest while running with the noctua fan.

That would be very nice. It would serve as a point of reference and for comparison regarding the efficiency of the cooling arrangement. I am not sure what the more experienced RPi users in EnOS community think of overclocking but all the videos I watched come with a disclaimer of the sort “Do it a…

Just FYI [image] Raspberry Pi Documentation - The config.txt file The official documentation for Raspberry Pi computers and microcontrollers I go with over_voltage=5 arm_freq=2000 gpu_freq=750 Pudge
