Excellent, no-fuss video. Great temperature control results. Fans are great when operating at home, but in the field, where power is limited, something else is needed.
finally someone which knows basic linux commands and use it correctly, not like the many which did temperature testing in last month continuing to press cursor up and enter to repeat last command...
The orientation of the board , the heat sinks make a significant effect for natural cooling. You need to create a chimney effect to cause the heat to increase air flow. Orientate the heat sinks so the channels are vertical and place a duct to direct the air. Simplest is a flat card just off the ends of the heat since at about half to the width of the channels. Nothing on the sides. As you make the duct more complex like add sides and extend the duct above the heat sink the air flow will further increase since hot air is less dense then cooler air.
I see your heatsink installation in a different place than suggested. others have said largest heatsink on the CPU, memory module (medium), smallest on the USB controller. why did you choose the power supply?
excellent video as usual, i prefer passive cooling with no noice at all (i took a heatsink that is like 5x5x7 cm and put on haha, but it would have been fun to know how much noice the pimoroni fan make.
@@CrosstalkSolutions I use the Raspberry Pi 4 with PoE Hat, but without the noisy Sunon fan. I created my own case for 30 / 40mm fans. With a 30mm 5v "Pi Fan" without heat sink, I end up with the stress test at 60.0'C. I hope I could help you a bit.

@@frits183 First off, I'm not a Linux programmer, when a gui is available I use it. Secind, I just monitor - not graphing or making a table. In Raspbian - Right click the menu bar - select panel preferences - select panel applets - select add - find Temperature Monitor and select it - select add - move it to where you want it.
@@squalazzo try overclocking it to 2GHZ and see if it still isn't thermal throttling. Also if it's under the thermal threshold, sure you won't see any performance improvement but running it hot even though would decrease the life of the cpu, potentially causing it to fail later.
@@Pngwolffman I have overclocked my Pi 4 to 2GHz. I'm using a cheap pi-fan with no heat sinks for cooling. The temps never get close to the throttle point. Heat sinks are not necessary on a fan cooled Pi 4.
All is good until I put in..... sudo nano -w my-temp.sh at this point in the video he says he's going to edit file and I assume he hits enter after entering the line above.(does he? or does he do something special to edit file?) It takes me off of the main screen with the "my-temp.sh" listed at the top with commands at the bottom but there is no text at all. I ctrl exit out and when I enter.... sudo chmod +x my-temp.sh it says .... chmod: cannot access 'my-temp.sh": No such file or directory Please advise
I've been trying to get a raid NAS working and struggling. I am going headless basic Buster Raspbian. When compiling the Raid 1 disk in mdadm I get stuck at 6 percent. Got the pi to start a samba server on one ssd but can't get raid to work. Anyone got any ideas?
Inside my my-temp.sh script, the console says permission denied when I try to get the CPU temp. How do I fix this? I've tried forgoing defining cpu and putting the temp location (like you did on the console earlier in the video), and it did notice useful. Either I get an error that says permission denied, I get a 0 where the temp output should be, or it acts like there is nothing there and doesn't print the CPU temp.
People who worry about Rpi cooling are fairly idiotic; no offense. But if you're pushing the system hard enough to consider cooling ... First, ask yourself why are you using the Rpi in the first place? Use something else and have a better experience. Or like the people who dive deep into overclocking them. You might as well overclock a ham sandwich with extra mayo thermal paste while you're at it because that makes more sense.
R.Pi 4 is a much hotter beast than 3, so you comments mattered more in the old days. Without a solid heatsink, throttling is very much a thing. Aluminum cases that thermally connect to the CPU (and perhaps memory) are very effective. I just got an Argon One case and passive cooling works quite well, with a fan that only engages based on heat. Really depends on why you Pi (yes, making it a verb might annoy some, but it is concise).
As far as I’ve seen in other videos and articles, the command “vcgencmd measure_temp” does not just measure gpu. It measures the CPU/GPU (SOC Chip).

Like the low profile of this cooler. Definitely use it for my custom crampy enclosure.
running my 4B on a GeeekPi Raspberry Pi 4 Case with ICE Tower Cooler @ 27 deg C with a 4020 fan @ idle very happy

Thank you. Very clear and very helpful. Did this today.
Very informative, though you need to read about hysteresis error 😂
have you tried replacing the stock heatpads with 1.5mm thernal pads from gelid solutions?
Great video! What is the cfm rating on the Pimoroni fan?
You are overusing the sudo command a bit at the beginning. The only needed was this one used wit apt-get
2:13 doesn't work for me - maybe only on Ras PI OS but not on ubuntu desktop - right?
What about those little cases with heatsink and fan?
amazing video
Thanks as always. Thoughts on the official POE HAT being able to do the cooling?
It should be comparable, but I didn’t test it.

The second CPU command doesn’t work - it states “no such file or Diretory” - using ras pi 4 - 8gb model
I just use the temp on the task bar.
How ?

you just explained a simpel way to do it.
@@frits183 Thank you.
Awesome video, tx
what would be the temp distribution with the Heat sink and an enclosed case with a fan mounted to the Case?
Great shirt
Hi, is it comparable with the official poe hat?
If you overclock it to 2Ghz, can the Pimoroni Fan still keep it below 80c?
mine is 68C degree when i am running 1 youtube video on firefox. Not sure this is normal?
why don't you just use cockpit?
Great Video.....tks ... great idea
You know what's better than a fan shim? A heat sink *with a fan!
no, in various youtube tests resulted that there's no real advantage, the fan is enough

Nice video, but I think that this "stress" command didn't stress the GPU...

Please advise
Copy and paste the code into the empty screen. He already has the file created. You don't. Code is in the link provided in the description.
I would like to see you meassure the room temperature as well, and maybe test at different room temperatures

I can get the CPU temp in the console, just not in the script??
I had the same problem, the first time you run the comand you have to type: sudo chmod +x my-temp.sh and then type: ./my temp.sh. it worked for me
intresting
shmod? I always say c-h mod.
He said chmod.... 'ch' and 'sh' aren't pronounced the same
Mod Shmod. Yeah, I don't treat it as a single word, preferring c-h mod.
