- $2 for 5 PCBs Any Color jlcpcb.com Welcome to a new Voltlog, as we all know the new Raspberry Pi4 has some cooling issues so in this video I take a look at a passive cooling solution and whether or not it’s good enough for most uses.
While some of the over heating issues of the raspberry pi 4 can be solved by a firmware upgrade, the core issue remains, we have a more power CPU which produces more heat and the standard raspberry pi plastic enclosure is no good for removing all of that heat.
The alternative presented in this video is a completely passive cooling solution, it's basically an aluminium enclosure that sandwiches the raspberry pi in between, thus ensuring cooling of the main components.

I bought absolute the same heatsink and forgot to measure the difference! Now I know that there is a huge one!
Thanks for the video!
Great video. I purchased a passive "armor" like this for my Pi 4, and it really does a great job at protecting the Pi and keeping it cool.
Thank you, and may I say I really appreciate how well spoken this video is. It is an excellent example for anyone hoping to provide high-information density material. Impressed.
I'm thinking of purchasing a Raspberry Pi and wanted to work through all of the potential issues before I buy it. Thanks for the helpful video!
Good video man, i was confused if i should get this case or not but your in depth explanation, convinced me that i should get this case, just ordered mine thanks for the video man :)
Thanks! Very good review. I just bought the same case and now I’m confident that it will serve my needs.
3:24 To heat sink manufacturer: "You had ONE job .... 🤦🏾♂️"
Nice... The latest Passive cooling case, comes with 2 small fans as well.
Thanks for making this video. Very clear and simple overview.
My Pi4 does exactly the same... about 68C when doing very little work. I agree 80C is achievable very easily.
I also have the red and white case, which is pretty and nice looking, but sadly impractical due to poor thermals.
I think the back is taken over as is from the PI 3Bplus version of this case. All pi 2 and 3 have their ram chip on the bottom side. So they didn't bother to make a new tooling for the Pi4 as it seemes to fit without interfeering with any other components... you could get some benefit though, by using a silicone pad between the bottom housing and the PCB. Though I'm curious about one thing: what if you mill out that raised piece of metal, use a thick and soft silicone pad under the entire PCB to get more heat to the bottom part of the housing? :D Just some early morning thoughts!
Yes this could very well be the same tooling using on the pi3, haven't checked but it would make sense for it to be that way. Having a big thermal pad for the entire bottom area of the pcb would certainly improve the heat transfer, by how much I don't know but probably something measurable. It would also depend if you can get some airflow past the bottom side fins, because if it's just sitting flat, it wouldn't help much.
I don't think thermal paste would work with such a big gap so you would have to file down the posts. Even then the different heights of the chips would be another problem so you are kind-of stuck with thermal pads, which seem to work great anyway.
Definitely, solder paste is only effective in a very thin layer which implies no gap between device and heatsink. The paste should only fill in small irregularities in the surface between the two bodies. So you are right, with this cooling solution thermal pads are probably the only way to go.
Have you tested this heatsink out with a 2000 MHz overclocked R-Pi?
can you overclock to this and test temps?
i used this regularly at 2 ghz, played dreamcast games fine and rarely goes higher than 60 degree Celsius
I have this case but it tend to block my bluetooth .
Is there and way to get around that or boost the signal?
the passive heatsink is very good at 4GB Raspi4 - but a GPIO 2x20-pinhead female does not fit - simply use a 1mm flex-disk to fix it - 0,5mm more space and the pinhead fit perfect. Without fan - absolute silent working - perfect for me!
Video part 2... investigate impact to wifi performance?
Now I see why my rpi3b w/armor case+fan never turns on the fan.
yeah, it never gets hot enough :-)
I ordered this and thought of I would still order flirc case, but with this video, you stopped me from spending more. I tried several case and none of them is really working for my use case.
Still relevant today. I subbed 👊
What type of screws is used for the pi4 cooling heatsink? Looks like machine screws, but I would like to know what kind and what length these are as I need to use standoffs instead of screws for my project
I just jerry-rigged an old 80mm fan running @ 5v, silent but plenty of air movement to prevent throttling!
Brilliant video. Very nice work!
Another thought: could you do a video with a head to head comparison between different passive cooling cases and also introduce the variable of the position of the PI? Like: laying flat on the desk, flat on some risesrs to give it 2...3 cm of clearance below... on it's side, etc...
I don't have any other cooling cases but it's pretty obvious this one does a good job and placing it in a way that allows for more airflow will improve the cooling a bit but it's not necessary to think about that unless you are running it 100% load, all the time, in a hot environment in which case you would probably want to run your own tests just to be sure.
I use the Pi52 tower heatsink and get temps maxing out at 49C with sysbench running 4 cores at 1850MHz, GPU at 700MHz for 30 minutes. Looks cool too. :)
That active cooling solution sounds like it would provide the most cooling for a raspberry pi 4.
@@voltlog I have a Flirc case(case is heat sink) by itself it limits out a 74C(fully loaded for 1/2 hour) in a 75F room. However if I put a 120mm 12v fan running at 5V it is dead quiet and limits out at 44C.
Thanks man. Great content. Keep it going.
Great eval! Thanks!
great solution for cooling management and as a case. looks great as well. very affordable and tough. I doubt the aluminum will affect the wifi very much?? but Im going to look for one for my Pi 3B+, I have several for my 3D printers and this would be so much nicer...thanks
I've been using a Pi3 for my 3d printer as well and it was put in the original abs box but now I'm thinking to switch that one to an armor heatsink as well because it looks so much nicer and ads the cooling.
You'll use a thermal pad from your own "stash". Been a long time since I heard that word used :-D
I really don't get this Pi4. I have all of the other ones, from the first model pi 1B, zero etc running here with a purpose, but this one I failed to press the 'buy it now' button. All the reviews and tests seem to go about the cpu heat and coolers. Have you tried to underclock it and check if it runs as hot as the model 3 for example?
Pi Zero W is the coolest of them all, IMO.
@@NETBotic Coolest in several forms that is. Ran one this summer for weeks on end on a solar panel and a 18650 board (ups) using moode audio player to send audio to a BT speaker. Now it is running pi-hole directly fed by the USB port of the router. I seriously love that Zero W, ok it's not that powerful but so what or so Watt..
Thank you
👍
you have the wrong HS case , the one that you show in the video is for the pi3 and not pi4 !
No, it's a universal case for both the Raspberry Pi 3 and the Raspberry Pi 4.
For the Raspberry Pi 4, all three thermal pads go to the upper shell.
For the Raspberry Pi 3, two thermal pads go to the upper shell and the third to the lower shell.
In all cases, it's recommended not to stick the pads to the heatsink but to the chips.
I bought the 2 fan version, but youll be better with fan less version, fans get you maybe 1degree less, they do nothing, but as passive heat sink is pretty good 40C on idle, and 70C when using ffmpeg for long video encode. Thermal pads was the worst, does not stick and could not get off protective film, so my results may be better with proper pads. The island for ram was higher than cpu one, i need a very thick thermo pad. there was small island on usb/ethernet chip but its kinda in wrong place. Overall i really like it.
I had the 2 fan version for the PI 3B here for a while and i just noticed that the fans are almost sitting flush on the aluminium. There is almost no space for the air to flow, except some minor residual channels, left over from milling away the cooling fins to make room for the fans. I didn't try the case yet, because i have some glued on coolers that i need to remove first, but maybe offsetting the fans from the aluminium a bit (e.g. with standoffs) could increase their effectiveness. Not sure if it's the same for the PI 4 though.
@@bernhardreinel maybe raising fans could help but they move very little of air. For my purpose i disconnected fans and passive cooling is enough. I mainly use pi4 for apache mysql learning/developing and ffmpeg stuff which is surprisingly good for such small device. I written script that basically monitor folder for video files and convert it to my specification one by one, and never saw throttling. Still ffmpeg on rpi4 is faster than rpi3 by factor of 2. One downside is h264_mmal hardware codec on rpi4 doesn't work properly for me.
I wonder what about the wifi card as you said. Is it that bad?
did you found any issue in this case like wifi ?
Thank you for this video
Can I use thermal paste instead of those thermal pads?
I bet the pad is thicker than the paste, and he showed that the heatsink does not even line-up with the raspi 4 components so it's a NO
Thanks for sharing !
It looks pretty :)
They look painted, not anodized. That could also affect the heat transfer.
Yeah, I was thinking the same... a little sand paper to expose the metal and then use the silicone pad or thermal paste may "win" you an additional 0.5° up to 1.5°C degrees... again, just an early morning thought!
that may be true from a technical point of view but really not relevant as the difference would be marginal. If you want to use this cooling solution you will be pleased by the results as it is.
Did you test the WiFi performance before and after installing the full metal heat-sink? I bet you will notice a decreased signal due to the metal body of the heat sink covering the onboard antenna.
He mentioned this specifically at 5:40 🙈😂
When you talking, i ear Ivar the boneless from Vikings XD
