I can't decide on whether it's beautiful or monstrous. But compared to the Flirc case I have this one has heatsinks for other chips as well as for the CPU. So better heat dissipation I think. At a price. ..Randomp wrote: ↑Thu Aug 01, 2019 12:36 amJust got my Barch Designs Pi Holder machined aluminum case for my 4GB Pi 4. It's very pricey at $70 USD, but I figure well worth it for piece of mind on a machine running 24/7 and avoiding fan noise and dust.
Ran a sysbench stress test on it for 10 minutes and it did not go over 58C.

Makes the Pi into a tank, but I don't think it's for everyone. It is noted that it is likely to reduce Wifi and Bluetooth range, but I use neither of those, so I can't really confirm it in my use case.
I also ordered a Flirc case, but that has not shipped to me yet. I don't have too much hope that it can compete with this case, but it should do just fine for my 2GB Pi 4.
Sounds more like "blipping" an enginejcyr wrote: ↑Thu Aug 01, 2019 1:14 amToo short mark pulses will not allow enough time for the motor to spin up, but duty cycles of 25-100% in mark-space mode work well to provide variable fan speed. Fan blade inertia takes care of smoothing the spin and pulses are not audibly perceptible, nor does the motor squeal.
That one looks awesome. Did you noticed any difference in range, when it comes to using Wifi/BluetoothRandomp wrote: ↑Thu Aug 01, 2019 12:36 amJust got my Barch Designs Pi Holder machined aluminum case for my 4GB Pi 4.

Yeah
Sorry, mine is set up as a headless server using Ethernet. But either way it's right next to my router, so WiFi would probably work just fine for me.webbsmurfen wrote: ↑Thu Aug 01, 2019 7:46 amThat one looks awesome. Did you noticed any difference in range, when it comes to using Wifi/Bluetooth
You need to run cpuburn-a53 to really test your setups. Also you probably want to overclock by 10% without any over-voltage (I have found my RPi4 to be stable with 15% overclock with no overvoltage). The goal is to not thermal throttle for as long as possible on maximum load (bonus points for doing it at the lowest cost and lowest impact to your workspace... i.e. noise, access to ports and gpio header).Ultrabit wrote: ↑Thu Aug 01, 2019 6:04 pmI thought I'd share my experience with colling my Pi4 B+. Granted I've not done stress tests etc but still I thought someone might find it of use. I'm using the metal case in the photo below.
Case lid ON, no heatsink at idle 69 degrees
Case lid OFF, no heatsink at idle 61 degrees
Adafruit 15x15x15mm heatsink case lid OFF at idle 61 degrees (ie. makes no difference at all). Heatsink noted to have got very hot.
28x28x18mm heatsink from Ebay/RS case lid OFF at idle 54 degrees
28x28x18mm heatsink from Ebay/RS case lid ON at idle 62 degrees (a reduction of 7 degrees in total).

Yes... I am running the same script. At stock clock setting of 1.5GHz I am not seeing thermal throttling with my Adafruit heatsink. It's only when I allowed overclocking to 1.65GHz did I thermal throttle after 1 minute.tdimike wrote: ↑Fri Aug 02, 2019 10:00 pmI'm seeing 17.4 degrees ambient currently and have just run cpu burn with the following guide :

As suggested I ran the burn test again, I ran it with an overclock and a touch of overvoltage (1) at 1750 clock speed and got a peak temperature of 51 degrees. I'm really happy with the cooling capability of this setup and it makes minimal noise also.chipace wrote: ↑Sat Aug 03, 2019 12:08 amYes... I am running the same script.

Interesting so taking the difference in starting temp into account the difference is 4'C. Hmmm... It's still a beautiful case, but I'm not sure if it's worth itRandomp wrote: ↑Sun Aug 04, 2019 2:03 amSo I finally got my Flirc Kodi Edition case to test against my Wicked Aluminum/Pi Holder case from Barch Designs.
Room temp is about 80F or 26.6C. Tests were taken consecutively on two separate Pi4s in the same exact location. The tests were started at about the same time after booting up. The Flirc case is housing a Raspberry Pi 4 2GB while the Wicked Aluminum case is housing a Raspberry Pi 4 4GB version. This should not affect CPU temperatures, but I just want to be transparent about the variables.

A 9 or so degree difference in peak temperature. Of note, I did not use the included thermal paste that came with the Wicked Aluminum case. I used Arctic MX-4 that I had laying around. Flirc case is using the thermal pad that was included with it.Code: Select all

I have now (finally!) received my Pi 4 and have it installed in a Flirc case, and my limited testing confirms what you have found. The one downside of the Flirc approach is that, in the steady state, the entire case gets very hot - probably only a few degrees cooler than the measured CPU temperature, so you have to be fairly careful about where it is sitting and need to make sure that no-one (including yourself) touches it if/when the Pi has been working hard for a while.
I'm not sure why exactly the starting idle temp was lower, but ambient room temperature was identical in both tests. It might be that the thermal pad is acting as a bit of an insulator because it is quite thick... Considering that temps jumped 10 degrees immediately after the first reading on the Flirc and rose a lot more steadily with the Wicked aluminum seems to kinda confirm that I think. I'm going to try the test again when I have time in a few days.jj_0 wrote: ↑Sun Aug 04, 2019 10:14 amInteresting so taking the difference in starting temp into account the difference is 4'C. Hmmm...

Btw, I ordered this case which also cools more than only the CPU. I'll post some numbers when it arrives. Might take some time to arrive though...
What I think is that the point is to stay below throttling temperature, and the $15 Flirc does that (mine was $11.20 pre-order for the non-Kodi version), so that $70 case seems like a huge waste of money (to me, anyway).
Heat isn't only bad because of throttling. Extended periods of heat can eventually lead to premature failure of chips. So even if it's below the throttling threshold, it can still be detrimental in the long term.HawaiianPi wrote: ↑Mon Aug 05, 2019 5:16 amWhat I think is that the point is to stay below throttling temperature, and the $15 Flirc does that (mine was $11.20 pre-order for the non-Kodi version), so that $70 case seems like a huge waste of money (to me, anyway).
Have you tested wireless performance on that expensive case? Cases that surround the Pi in metal seem to reduce WiFi and Bluetooth performance much more than the Flirc (which has plastic on the bottom and part of the side where the wireless antenna is located).
I know it is highly unlikely and doesn't even apply all that well to my use case for my own Pis since I am likely to retire them early for the next model. Still a true fact though.
I haven't manage to retire a Pi yet (apart from the two that died - a 1A and a Zero). Most of the rest are still in use ( I keep a few spare for projects) Including my first early 1B.
Any suggestions how this might work with the sense hat please? Need to extend the gpio header?clicky wrote: ↑Sun Jul 14, 2019 6:33 pmFan SHIM our favourite pirates are selling makes temperature under control at all times. After installing it I haven't seen it going over 49ºC at any point. And - it is solderless installation - so no need to 'dedicate' PI to run with that particular shim.
Alternative (from my perspective) is what I've done for my son's Orange Pi - made a case with fan 1cm away from PCB constantly working extracting air. I suspect that (even being enclosed) it would keep temperature low enough...
