- Raspberry Pi 4 passive cooling, plus firmware update that significantly reduces the temperature of the Pi. Tested in this video are the Kodi Edition FLIRC case, and the “Aluminium Heatsink Case for Raspberry Pi 4”.
The Kodi Edition FLIRC case can be found on Amazon.com here: amzn.to/36S79tL (affiliate link). Do make sure that you get the one for the Pi 4, not the previous FLIRC case that fits the Pi 1B+, Pi 2B and Pi 3B(+).
There are lots of different two-part heatsink cases for the Pi 4. I purchased mine from The Pi Hut here: thepihut.com/products/alumini... But an identical-looking model from Geekworm is on Amazon.com here: amzn.to/2O3s6cP (affiliate link).
My previous Pi 4 cooling video featuring the Pimoroni Fan SHIM and ICE Tower is here: • Raspberry Pi 4: More A...
And my first Pi 4 cooling video in which I create a custom rig using a 40mm Noctua 5V fan is here: • Raspberry Pi 4 Cooling

Not only is your Pi "fed up" with all the cooling changes, I'm sure it's "fed up" with factoring numbers. Great video, lots of work.
We all Appreciate your Efforts of Conducting the Tests again with Active Cooling Systems after the Firmware Update.
Greetings!
Thanks!
I guess you could call this passive aggressive cooling
Clever! 😆
Clever indeed! th-cam.com/video/6DC9xez5pxU/w-d-xo.html
🤣
That's hilarious!
So good.
I'm glad that you re-ran the active cooling cases. That was a lot of work, but the responsible thing to do. I have learned to count on you to do the responsible thing.
This is the best video of the Raspberry pi 4 since the launch of the Raspberry pi 4.
I've used the Flirc case for years so I had to get a new kodi edition for my Pi 4 and it looks amazing.
We also appreciate the EXTRA time you took to run the previous tests too :)
Love your impromptu, couch conversations. Even this was on the road. Good job, sounded very cool!
best tech show on youtube. always good information, and a funny 80's style, reminds me of Commodore 64 shows, lol.
And without annoying background music.
Can you still smell the BBC micro computers in your head
Well, I WAS going to get the Official Case but after seeing that chart, I'll be getting a FLIRC case. What a difference!
I love how these videos sound like the educational videos from my childhood, but are about modern technology
These videos always put a smile on my face. It's just the perfect combination of great technology, a simple and clean video design and of course, the most charming host
Superb host, I will agree.
Thank you Chris, i am a firm(ware) believer in passive cooling for RASPI that sit a coner just doing datalogging and behind equipment performing various minor media tasks such as Kodi servers and the like in a quiet man cave or she shed!
I have the aluminum heatsink case and it's fantastic, love it! Highly recommend it!
I have an old Raspberry PI but after watching this I am going to get the Kodi case and the PI 4 to replace my core 2 nuc (DVI output only). Thanks for this.
Active cooling solutions test clearly shows that 7 sysbench iterations are enouch for CPU temperature to stabilize. But those big passive heatsinks have a lot higher heat capacity than active coolers, and the test might not be able to heat up the CPU to the maximum temperature (which can be seen from the results, the temperature only increases for passive coolers and never decreases). In fact, in both passive coolers tests the last reading is higher than the previous one that shows the temperature will rise more if the test continues.It would be more interesting and informative to see the resulting temperature after it truly stabilizes (it takes only about 11 minutes for the current version of the test to complete, so increasing the time to 30-40 minutes might be enough). And, by the way, I suspect those heatsinks might not be that safe to touch after the test.
This, exactly
Yep. I'd guess it's going to max out in the upper 50s but you should at least run enough iterations to get some duplicate peak readings before stopping the test.
I did exactly that with the FLIRC case and the temperature finally stabilized at 58 Celsius after 30 minutes. The test ran 60 minutes. The case got warm but was still safe to touch.
I ran ffmpeg for 2 days on a raspberry pi 3 with this case. I never made it over 60F. Ffmpeg uses all available processors, and will use 100% of the cpu. I suggest using "nice" with it, unless you really don't plan to be using the computer for anything else.
Valid point. With passive cooling only, it takes at least 30 minutes of 100% CPU to reach equilibrium. Measurements after only 10 minutes are very much influenced by the initial conditions and should be discarded.
I got the FLIRC case for my RPI4 4GB and it's beautiful and works great.
Thank you for testing. Passive cooling is the best.
Your channel just keeps getting bigger! Good for you!
What a cool idea for a video. I am always overwhelmed with the selection of cases and cooling solutions. Now I have a good idea of what to buy. Thank you.
Long time subscriber and also a tinkerer of Raspberry Pi. Just wanted to say thanks for your informative videos as I've learnt a lot from them and passed this information on to others as and when they ask. Keep up the good work Mr Barnatt.
Thanks.
Well Done Sir. You certainly do a thorough test. We can always trust you to do so.
great information. thanks for taking the time to rerun all those tests
Another masterpiece. And nice to meet a new family member: Allen the Key. Cheers from Spokane!
I just realized you don't have a PATREON!!! I love your videos. I would love to be able to contribute directly to you work.
I managed to get one degree cooler in my Flirc case. I think the only difference between your setup and mine was that I initially bought a Canakit which came with 3 heat sinks (CPU, USB and, I think, Network chips) so when I got the Flirc case I only removed the CPU heat sink leaving the other two since they did not interfere with the case. I am very happy with the Flirc and haven't seen a single thermal throttle to date.
I loved the THX 1138 reference! I really appreciate the subtle bits of humor you sneak into your viedeos.
temp=38.0'C
temp=47.0'C
temp=48.0'C
temp=49.0'C
temp=50.0'C
temp=51.0'C
temp=53.0'C
temp=53.0'C
Thanks for sharing your results -- and appreciating THX 1138. :)
Ice Tower and Noctua fan just outperforms all cooling methods, but these passive cooling solutions are also performing well.
Thanks for another video. I eagerly wait for these to arrive.
Thanks professor Christopher .the ice tower still at the top and the cheaper passive design looks good nice on the new firmware .
Thank you for the experience, watching on a Pi 3 with and 8.99 case , acrylic top and bottom with fan, after two of your videos, has a 53 degree internal monitored temp, sd card is from a Pi 4 and has the latest update. Always learn something when I watch your videos.
Hi, thanks for your video!
I've both used the Flirc case as well as the 'heat sink as a case' style (exactly the same model as you use). I'm using my Rpi4 as a 'Stellarmate', a tool for astrophotography. What I've found is that when using the Flirc case, when I use my Rpi4 in hotspot mode ánd use bluetooth, it loses the hotspot. With the 'heat sink as a case' the Wifi transmitter is less obstructed (actually visible from the outside) and doesn't cause this problem of losing the hotspot. I suggest it's some kind of interference.
It's maybe interesting to run a test on that with your better understanding of computers.
Cheers! Bart
Very impressive that the software update could make that big of a difference in temperature. Also, “Allen the key” - loved it!
Pretty sure I just found my next Pi case, thanks EC!
Wonderful review !
Can't wait to get my hands on that fine machine.
i have several of the "Aluminium Heatsink Case" for my 3 and 3b's and i ordered one for my new 4.
I order them at aliexpress and are so cheap and work excellent.
Good to see some tests and comparison.
Great video as usual! In this case has helped me make a definitive decision on the cooling I am going to use. Thanks !
Thanks for another great video Chris. These comparisons are great value, and thanks for the pricing info also.
Thanks for the firm updates!
Allen the key joins the family..... yeyyyy!!!!!
Absolutely fantastic review Chris. Thank you.
I got tired just thinking about how much work it was to produce this terrific video.
I really like the way the heatsink case(2 pieces) look.
Thank you for an excellent video. The video does an excellent job of explaining the process for the testing the cases and providing potential consumers with results that are trustworthy.
Thanks a lot for this information! In this video you answered several questions that I've had on my mind for a while + I learned new things :)
I suspect then, that official case will now smash the 90 degrees bomb scare score now too? Well done the Pi lads! Thats a top bit of software engineering. Very impressed. Thanks Chris, for doing them all again. It deserves to be highlighted. Well done.
Love your 1970s OU Broadcast Style...waiting for Massive Shirt collars...lol
All that's missing is a B&W telly an a Kipper tie.
Great video, thank you for your works presenting all this in this nice format.
I kinda genuinely fell in love with the Raspberry Foundation. Consumes less power than some peoples light bulbs, yet is a super affordable computer, if you want it to be. Awesome!
I was thinking about making some little server on Raspberry Pi, that would even run at night and would not disturb me.
Now I know a good solution against overheating.
Thanks for the video!
Thank you for taking the extra time to do redo the active with the firmware updates. I'd kinda be curious to see a row of the Pis in the heatsink cases fair inside a square tube with a fan on either end pushing and pulling the air through...
Wonderful video! I learn something new and, more importantly, useful every week!
I bought the second one, and it works really well for me. it's on the pi I'm watching this video on.
Great video, thanks for sharing your tests!
I bought this case when i first got the pi 4, it works pretty well.
This was very informative and helpful, thanks for making the video!
Loved the GL ref. :)
I have never seen a video on the Explaining Computers channel where pressing the "like" button felt like adequate praise. This one is no exception.
I should probably copy your testing script and see how well the case with fan I bought does. I'm glad you re-tested the previous cooling solutions, as it truly highlights the impact of those updates. I'm curious how the official case fares. Hopefully, it would stay below throttling temperatures.
Another rasbperry pi related video from my favourite channel.
you illustrate that the Raspberry Pi 4 is one tough unit ,excellent results both
That was a lot of work retesting, good job!
It was! The video took a lot longer to make than I expected!
Man the new update is awesome
Very good video, Chris. Can't wait to buy myself a raspberrry pi 4B
Hi, interesting video, as usual. The last summary table missed the no-cooling test results. They would be useful to check how the update performs in your same ambient conditions. I used the same passive heatsink case as you, but by looking inside the fully mounted thing I saw the cpu sticky pad wasn't touching the case log. So, after verifying the ram chip doesn't heat considerably, I placed two sticky pads over the cpu and I got a better result. Bye from Italy.
Excellent comparison
Really great video Sir. I want to buy a RPi 4, and thanks to your video now I know what type of cooling to purchase.
i just love your videos thanks for all the effort
14:04 Alan the Allen key. I like this.
Especially with passive cooling, the mounting position is crucial.
I really liked that last case -- it had a very "industrial" quality that I thought looked very cool, and I liked the way the top piece fit behind the USB and Ethernet ports. And it was the least expensive of all the solutions in this video. I think that's the one I'd buy if I were in need of a cooling solution for a Raspberry Pi 4.
Very Nice the case's are getting better
Of the two tested I prefer the Aluminium Heatsink Case, simply because you can get to the GPIO pins. I suspect you could add a fan with some self-tapping screws that gripped between the cooling fins on the top. Obviously choosing screws that were not too long. The Ice Tower remains the one to beat, so top marks to them once again.
My own follow-up, after I upgraded the firmware, aluminium heatsink, with 2 fan 25mm (they are under 20dB, so virtually silent), and with managed speed:
temp=47.0'C
temp=58.0'C
temp=60.0'C
temp=61.0'C
temp=62.0'C
temp=62.0'C
temp=62.0'C
temp=61.0'C
The starting temperature is high because the RPi has been sitting in the non-aircond room all day long, so it was over 30C at that time and even right now, the aircond is set at 27C.
I put the heatsink from a quad-xeon server on my RasPi4. Never gets more than 2 degrees above ambient now. It's not pretty mind you and it weighs over a kilo now but it is at least 100% silent. :)
Impressive results.
Sharp looking set up.
Very well executed and presented, Chris! Interesting!
Thanks Don.
Very useful to know about the firmware update.
I recomend putting it vertical, the heat transfer by natrual conveccion will be a lot better, and the board will be cooler
Very interesting and informative video.
I appreciate all the effort you obviously put into making it.
😊
that aluminum heatsink case is called the raspberry pi armor case. The bottom heatsink is carried over from the previous versions where the pi had the ram on the bottom. it's still there for ease of use and design and just makes it look damn good.
There are lots of names for the case -- the castings are sold generically by many companies. :)
The copper-colored heatsinks have a smooth bottom.
huh, i didn't know about the smooth bottom varient. guess i need to hunt one specifically to find it
Wonderful and thoughtful testing! Well done!
Thank you very much!
Lovely job as always, thanks very much.
I have a pair of Pi4s with Flirc cases and I agree that the temps stay low, especially with the updated firmware. I couldn't justify a passive cooler for these, and the silent operation is a plus. Now I just need true USB booting and the Pi4 will be perfect for my needs.
Great test
It wound be Fantastic to know the rasp. Pi 4 wit no heatsink in the charter too..
Thanks for sharing this great products👍😀
Thank you for slow maner of telling
It help to teach English.
Absolutely outstanding video. Thank you for sharing this
Thorough and well presented. Thanks.
Ahh passive cool my old friend
Thanks for your hard work. How much better would it be if you used the last passive cooling with a fan on it?
I have pi 1 model B, 2xpi 2, and 4x pi 3. I wouldn't buy a 4 b/c I didn't want active cooling. This video puts the pi 4 on my list. I skipped the 3+. I like my droid hc1 and was hoping for similar case idea with case as heat sink. I like the 2nd one better than the flirt case, but might just get 2 pi's and both cases.I'm just very opposed to active cooling for SBCs. Great video, Chris as always!
What a difference in ℃ after updating π.
Great job π foundation!
And of course, excellent video Chris!
Sunday delight!
R2D2 & 3PO love TPH002!
As for me, I'm all active cooling Burj Khalifa towers. 😁
Hi Elvira. :) I remain amazed how effective the new firmware is in improving power management. It makes you wonder what firmware changes could do in other systems.
@ExplainingComputers
Exactly my thoughts!
Makes me wonder what changes would we get on other systems just by firmware changes... 🤔
ExplainingComputers
Hey why did you use
“sudo apt upgrade” instead of
“sudo apt full-upgrade”
I've always said that Firmware Engineers are the finest people in the world.
Agreed. And they get so little credit.
Watching RPI cooling video in winter....😀⛄
Excellent. As always.
The Pi got excited with Chris doing a flirc!
I wish you would run for public office in the US. Somebody I could actually TRUST!
Donald Porter or at the very least he could do “Explaining Politics.Com”. Of course Stanley the Knife and Mr. Scissors would be helpful showing examples of how one could “cut red tape”.
Very impressed with this video, it shows progress, I think I might have been one of the first with a flirc case, it arrived to me on one of the hottest days of the year, I put it together, and started testing it out, before too long the pi was getting very hot, the red sign was on the pi and and the pi was giving off a dreadful smell, pleasant to touch it was not, like handling a kettle or a toaster, I had several flirc cases in the past, which were fantastic on the pi 3, I was so disappointed with this one, especially as I had it shipped in and paid extortionate taxes on it for me and I got one for my brother, which he wasn't going to want, but now these raspberry pi 4 run nice and cool, even with an overclock, good work pi foundation, though perhaps the pi 4 was rushed out, maybe things like this needed ironing out first and probably still do, I have had two raspberry pi 4 with display and sound issues after running beta berryboot, hats off to the official raspberry pi outlets who posted out a replacements straight away, so the raspberry pi stays my favourite SBC.
Nearly 2M sold - if we had waited until everything was perfect, we would not have sold any yet and everyone would still be waiting for many more months. And of course, no product is perfect.
Thank you so much this great video!
For hifi use, in a streamer for example, passive is the best choice.
Hi there and thank you for an interesting video. I suggest that you might supplement these tests by exploring what effect these various cases & heat sinks have upon the on-board wi-fi. Do they screen the antenna?
Nice. The PI 4 is like a mini sun so no small heat sink will do the job. For PI 4 with 8GB of RAM and heavy use I will recommend the active heat sink.
