Cooling The Raspberry Pi 4 With The Fan SHIM & FLIRC For Better Performance

[Tomin]

The only proper solution is a huge heatsink with a heatpipe with LEDs! Sadly not RGB, but eye-burning blue:

Yeah, RGB lighting would make Raspberry run so much cooler.

It shouldn't be hard to mod it to use RGB fan that would be controlled via GPIO.

From Michael Larabel's hard work, and by The Raspberry Pi Foundation's tacit admission, it is quite clear that the RPi4 is not usable without the addition of proper heat sinking; one more example of the unleashing on the world of an inadequate, and sometimes totally unworkable, Raspberry Pi 'solutions'--BUT which fulfils promises made by the Raspberry Pi Group, and which are conveniently 'swept under the rug' by circumlocution and dissembling.

The end result of all this generates two very important, and--sadly, in light of all the poor engineering design done by the Raspberry Pi Group--very real questions, to wit:

1) Is the Raspberry Pi 4 going to now be shipped in its only usable configuration: with a 'fan shim', or 'case-which-is-a-heatsink''?
2) Is the real cost of the Raspberry Pi 4 going to be ADVERTISED AT its real price $45.00 to $50.00?

...or do we have yet one more case of (a) 250 GB/s "Gigabit Ethernet" puffery, with all of Eben Upton's excuse-making ; and (b) "We've done our part--user, it's up to YOU to get it to meet YOUR expectations and get it to actually, you know, like WORK; we TOLD YOU WE'D DELIVER a $35.00 Raspberry Pi 4, and HERE IT IS..." on our hands?

Incredible. Unbelievable.

Still makes a good LED-flasher, though. Only it takes more power, now. And proper heat-sinking.

Thanks rpi for making the Odroid N2 look cool.

I'm a bit surprised this runs hot enough where even the FLIRC isn't quite enough to prevent thermal throttling. Perhaps they should look into something smaller than 28nm.

Price is a big issue for that. Maybe in another two or four years it would be possible.

Going bellow 28nm, is very costly..
28nm nowadays, its the sweet spot, everybody that tries to do something serious goes 28nm, if he can..
Bellow that, only Large Scale productions, of products that sell at least for some several hundreds €..

Amd and Intel do it, because they are the monopoly for x86..
In the graphics market, Amd and Nvidia can also do it, because of graphics monopoly/high price of the products..

Apart from this, only large scale cpus for Mobile Phones, and such goes bellow 28 nm..

China that is China,
Maybe will next year start sampling its Loongson 3C5000 at 16nm TSMC, and its a country with more than 1 billion people..but not enough for the required scale to go..lets say 7-12 nm( has the final product would cost a fortune each.. ).
Russia, the same, they are working at 28nm, expecting to go 16nm in 2021..

Good pun!

All RPi s have been making Odroid stuff look cool for a long, long time. Even now, the lowly XU-4 ( 2 GHz, EIGHT CORES; 2 GB RAM; uses eMMC for on-board mass storage; TRUE GB ethernet; Real-time Clock; true SATA3 interface for easily adding a HDD or SSD; and it comes with a fan, or large heatsink--your choice) sells for only $51.95.

The community support might not be as good. Does it run Rasbpian / ARM11 ELF?

Wrong https://www.hardkernel.com/shop/odro...th-4gbyte-ram/
that's $79 vs the $70 for the equivalent rpi, that's only 11%.

The community is better because there are not millions of unanswerd posts like on the rpi site.
Yes it runs Debian, Fedora, Arch and their derivatives. Kodi, Android, mainlin Linux, etc.

How warm is the FLIRC case itself under heavy load? I definitely want my Pi to be fanless, unless the case becomes too hot to even touch.
