"since it appears trying to actually do anything with it will kill it in any real sense." That depends on the processor, existence or size of heat sink, heat transfer connectivity between SoC and heat sink, ambient temperature and OS settings. Most modern SoCs have a temperature setting inside that the OS can read. If the processor gets too hot the CPU can throttle back the clock and reduce the heat produced. It could also schedule fewer or less powerful cores. Of course this slows down your computer. The other main consideration is ambient temperature. If the air around the system is really warm the heat sink can only exchange so much heat. The fan helps with this, but in the end you might still have the CPU throttled. This explains why some over locked machines used by gamers even use liquid cooling to carry off the heat from the circuitry. I have not looked into the RPi 5 enough to know the extent of the thermal protection it enjoys, but I would not discourage you from buying the fan to get maximum performance on benchmarks. There was a good "Toms Hardware" video on this with regards to the RPi 5 when it first came out. On Tue, Jan 9, 2024, 12:12 Tim Keller <turbofx(a)gmail.com> wrote: > I did get my pi5 in the mail!

I did get my pi5 in the mail! I went off and printed a case for it! I'm going to head over to Microcenter (possibly for lunch!) and buy a cooler for it since it appears trying to actually do anything with it will kill it in any real sense. Tim.

Reminder!! Meeting January 11th at 7pm Topic: Pi5! Location: Technocopia

by Tim Keller

Hey Everybody! We've got a meeting at Technocopia on January 11th 2024 at 7PM! The topic is going to be the pi5! I've gotten my hands on one and I'm going to do a show and tell. I've also got an 8GB pi4 as well so it'll be good to do a bit of a side by side as well. Time: 7PM Date: January 11th 2024 Physical Location: 44 Portland St. 6th Floor Virtual Location: https://meet.jit.si/WlugMA As usual we'll grab some dinner after the meeting and keep up the conversation. Later, Tim. -- I am leery of the allegiances of any politician who refers to their constituents as "consumers".

Hi John. Speaking for myself. Life has gotten in the way from me attending. I do intend to get back to meetings, though it may take me another month or two. As far as meeting content, just my opinion mind you, I think a good mix is helpful. It's a plus to have a talk or demo planned and announced a bit in advance when possible. "Low level" talks in my eyes are good too. I think a broad spectrum goes a long way, meaning over the course of several meets. A good mix might be a good draw for new members, as low level talks will be easier for novices and the other talks can help show what is out there beyond what they may have already learned.
