Best passive cooling case!

Sat Dec 24, 2016 9:51 am

I just want to start off by saying this isn't an endorsement but a review for those who want a cooling solution! I just bought a Flirc case and its whole body is made out of metal for passive cooling. I never checked before but my idle temp now is about 35C and holding 100% cpu utilization for a couple of minutes stays at a nice 58C.

Cons of this case:
It's screwed together so pulling your RPI out will take some work. (But you can remove the rubber top and pop off the top to access your GPIO pins, camera etc.
MicroSD is "stuck" in there, so there isn't a way to pull it out while the case is on.

(Only cools down the CPU)
I was thinking this would be perfect for overclocking etc, so here are some pictures:

**Edit** Uploaded pic for thermals. (10c lower than the regular case) 70 Degrees Fahrenheit is my ambient temperature.

Could you try running this and report the temperature after 10 minutes or so?
It uses NEON on all four cores to increase the temperature rapidly.

Code: Select all

wget https://raw.githubusercontent.com/ssvb/cpuburn-arm/master/cpuburn-a53.S
gcc -o cpuburn-a53 cpuburn-a53.S
./cpuburn-a53
This tool (bcmstat.sh) is handy for monitoring the temperature and frequency:

the SOC is the only one that needs cooling and that is a good case

Yes,
I was just wondering, before I buy one, how good the cooling actually is - can it prevent throttling under a truly heavy, sustained, load?

Yeah,
I've got one, gorgeous and efficient, cool in both ways, I've run Kodi on it for over a year, never gets hot, never even makes the case feel warm. Quite expensive, but you pays your money...

I've tried most of the cases, Pibow (two of those, one is the wooden one) Flirc is the nicest of them all.
Shortcrust is also a very pretty one, but the original one I think is only for the Pi 1, still gorgeous though, its my second favourite.
Here's my cases (so far!)

Shortcrust (The old one) (Very few left available)

Pibow

Pibow Timber - nice but very fragile before installing Pi, parts of mine broke in the post.

Flirc - runs Kodi, really pretty, but its sat under the TV so I can hardly see it!

Official Raspberry Pi 3 case - quite nice looking and functional, top comes off quickly to allow fitting of Heat-Sinks!

Zero case - fiddly to assemble

Improved version of most other aluminum cases, has passive cooling for 3 parts (SoC, Ethernet, RAM) just remember that you should use thermal pads with them.

Sorry to grave dig but I forgot about this thread, and decided to post the thermals.

Have you guys seen this one [1]? Also a full-body aluminum case, but thinner. Ships via aliexpress and fasttech (cheaper).

I've written a small command line tool for generating a signature temperature curve, stressberry https://github.com/nschloe/stressberry. If anyone wants to try it out, simply install with
```
sudo -H pip install stressberry
```
and run with
```
stressberry-run out.dat
stressberry-plot out.dat out.png
```
I'll be happy to include your temperature data in the plot so we can actually compare which is best!

There is a Gen2 Flirc case that is made for the Pi3. The Gen2 provides access to the Pi3 SD card and visibility to the LEDs. It's also supposed to have better metallurgy and molding due to improved manufacturing techniques. IMO, it is the best case for the Pi3. Yes, there are others that are full aluminum, but those will weaken the WiFi and Bluetooth.The Flirc has a plastic bottom that extends slightly up the side where the antenna is. The bottom has vent holes for air circulation, and a cutout for GPIO connections.

The other chips don't require cooling. The "CPU" (SoC) is the only chip that generates a lot of heat.

You can distinguish the Gen1 and Gen2 cases by the separation of the USB ports. On the Gen1 case there is a large opening for each pair of USB ports. On the Gen2 case all 4 USB ports are individually framed. Note that the Flirc web site is kind of a mess. They show pictures of the Gen2 case, but still have warnings about the LED and SD card Gen1 issues. I'm not sure which you'd receive if you actually ordered direct, so I got mine from Amazon USA (which specifically lists the Gen2 case).

Click picture for Amazon USA link (a quick search of the UK Amazon site only found the Gen1 case).

That one looks interesting, because it also has a non-metal area near the WiFi antenna. It's expensive, though. :shock:

The FLIRC Case is definitely a good one for the Raspberry Pi. One that solve the SD Card removal problem is the Mechatronics Art one, that have an easy access to remove the card. It also cools both the CPU and the USB Chip, and a reset button:
