**Thermal Testing with the Poly Plus Case from Argon One**

The process began by installing the Raspberry Pi 4 inside the case and attaching the fan. The next step was to enable the fan, which could be done in two ways: either by using PWM (Pulse Width Modulation) to control the fan's speed or by turning the switch to "On" to run the fan at full time. In this instance, we chose to utilize the PWM feature of the fan, allowing us to set a specific temperature threshold for when the fan would come on.

To enable the PWM feature, we first made sure that our Raspberry Pi OS was fully updated by running the command `sudo apt update` and then rebooting the system. Once we had restarted, we accessed the Raspberry Pi Configuration tool from the desktop icon and selected "Performance". From here, we were able to configure the fan settings for the new Raspberry Pi fan. We enabled the fan by selecting it as an option in the fan setting menu, but the fan GPIO needed to be set to 18.

Unfortunately, the current version of the Raspberry Pi OS has limited flexibility when it comes to setting the fan's temperature threshold. While we were able to enable the fan and set its speed, we were only able to set a maximum temperature threshold of 60 degrees Celsius, and not lower than that. However, this limitation can be overcome by editing the `config.txt` file.

To do so, we opened up the terminal and navigated to the location of the `config.txt` file. We then edited the file using `sudo nano /boot/config.txt`. The relevant section of the file is located towards the bottom, and it contains the following lines:

```

dt overlay,gpioFanControl=18,50

```

We were able to change this line to set the temperature threshold for the fan to 50 degrees Celsius instead of 60. We did this by swapping the `6` out for a `5`, effectively reducing the maximum temperature that the fan would allow.

To apply these changes, we saved and exited the file using `x`, and then restarted the Raspberry Pi using the command `sudo reboot`. After restarting, we were able to verify that our changes had taken effect by checking the temperature readings from the stress test software.

**Stress Testing the Raspberry Pi 4**

We used the stress test software "Berry" to stress test the Raspberry Pi 4. This software provides a lot of useful data, including temperature readings, and makes it easy to create charts that display our results.

First, we ran the stress test with all four cores maxed out for 10 minutes straight. After completing this test, we were able to view the resulting chart, which displayed our temperatures throughout the testing process.

We also wanted to test the Poly Plus case when overclocking the Raspberry Pi 4 CPU, so we repeated the stress test with an overclock of 2.1 gigahertz and the fan set to "On" at all times. We were able to view the resulting chart for this test as well.

Finally, we tested the stock settings for the Raspberry Pi 4, which included a speed of 1.5 gigahertz and the fan set to "On" at 50 degrees Celsius.

**Conclusion**

In conclusion, our testing has shown that the Poly Plus case from Argon One is an excellent choice for housing the Raspberry Pi 4. The case comes with a heat sink and PWM fan control, which allows us to easily manage the temperature of our Raspberry Pi. Even when overclocking the CPU, we were able to keep the temperature under control using this system.

The Poly Plus case is available on online marketplaces for around $10-$11, making it an excellent value for those looking for a high-quality case that can help keep their Raspberry Pi cool. Additionally, if you already have a case that you like and think might be able to fit the fan in, you can simply purchase the fan itself for $5.

Overall, we highly recommend the Poly Plus case from Argon One, as it is an excellent choice for anyone looking to build a powerful and efficient Raspberry Pi system.

"WEBVTTKind: captionsLanguage: enhey what's going on guys this eta prime back here again today we're going to take a look at one of the best budget cases for the raspberry pi 4. this is known as the argon 40 poly plus now along with the case itself it also comes with a pwm controlled fan and heatsink that attaches to the gpio pins of the raspberry pi 4. and the best part about this whole case is the pricing it's coming in anywhere from 10 to 11 i think it's 11 right now on amazon but it comes with the case and that heatsink slash fan combo that we're going to take a look at now in this video we're going to take a look at the case do a quick assembly and then i'm going to get right into some testing because i'm super interested to see how well this cools the raspberry pi 4 at the stock clocks and overclock and keep in mind since this is a pwm controlled fan we can actually set this up to come on at different temperatures but it also has a switch so you can keep this on full time if you really wanted to so along with the case we do get some instructions it's actually pretty easy to set up i'll show you how to do that in just a second and inside of here we have our fan and heatsink combo along with some rubber feet and the thermal pad to go on top of that raspberry pi cpu so as you can see here we got a little 30 millimeter fan with what looks to be a copper heatsink now it actually could be aluminum i'll have to check that out in just a second but overall i think it's a nice little design and it's great that this all comes with this 10 case so it's a plastic case we do have that ventilation up top and the top actually pops off very easily so you can access the gpio pins we have full access to the ethernet usb ports and the micro sd card on this case and when it comes to the included fan it's actually a nice little design we have that 30 millimeter fan along with this breakout to sit right on top of those gpio pins it'll make contact to the cpu using that included thermal pad and we also have a switch here we have on off and pwm so if you want this to run full time just turn it to on you can always turn it off if you want to and then we can have it software controlled to come on and off at any time using that pwm switch so let's go ahead and assemble this unit i mean it's super easy to do this case actually has three different layers we have the top layer mid section and this bottom plate which actually pops right off there's no screws so you don't have to worry about stripping anything out and as you can see inside we still have access to the cpu gpio pens the dsi and the csi connector on the pi 4. so the pi is going to sit right in here everything lines up nicely we have all of our hdmis usb type-c access to that cpu so we can set that heatsink right in here we're just going to pop the bottom right back on it's going to hold everything in place snaps on here nicely so it's not going to go anywhere if you need to transport this thing around now it's time to add the heat sink and fan combo they do include a small thermal pad that's going to go right on top of the cpu it has plastic on each side so i need to go ahead and pull this off real quick and once that's done we're just going to place this thermal pad right on the raspberry pi 4 cpu just try to line it up as best as possible here and now we can install the fan and heat sink this is going to slide right down on the gpio pins and now we're good to go i mean we have the raspberry pi inside of this case all that's really left to do is enable the pwm control on the fan you can add these rubber feet to the bottom and throw the top on the case and once it's all said and done it looks something like this i personally like the way this thing came out now it's definitely not a super flashy case but it's very functional and i do think it comes in at a pretty decent price so now it's time to get into some thermal testing and see how this thing really cools the raspberry pi 4. all right so now that we have the pi inside of the case and the fan installed it's time to enable the fan now if you don't want to use pwm just turn the switch to on it's going to run full time it's going to keep your pi the coolest but i want to utilize the pwm feature of the fan that way i can have it come on and go off at certain temperatures it's super easy to do with the latest version of raspberry pi os you need to make sure you're fully updated so hit up terminal sudo apt update do a reboot once you know you're fully updated we're going to head up to the raspberry pi icon preferences raspberry pi configuration performance and from here we have the fan setting for the new raspberry pi fan so we're going to enable this but the fan gpio needs to be set to 18 and from here we can only go as low as 60 but we can actually change this in the config.txt so if you want to keep it at 60 that's fine it will keep your pi nice and cool but unfortunately they've changed this up so we can't go under 60 right here i'll just choose okay so now that fan's only going to come on when the cpu reaches 60 degrees celsius but if you want to lower this temperature threshold we can open up terminal from here we're going to head over to our config.txt sudo nanoboot config.txt scroll down to the bottom here and you'll see we have the dt overlay gpio fan we've set it to pin 18 and it's set to 60 here but i'm going to go down to 50. so i'm just going to swap this 6 out to a 5. now i've set the temperature threshold for this fan to come on at 50 degrees celsius instead of 60. control x y enter now we need to reboot the pi one time to make sure everything took effect so we can type in sudo reboot i'm going to go ahead and reboot and then i'm going to get into some temperature testing so when it comes to stress testing the pi i use something called stress berry what this does is give me a lot of readings makes a log in the background as you can see we just started the stress test here maxed out all four cores for 10 minutes straight and by the end of this i can actually make an easy to read chart now the way it's sitting right now we're at the stock speed we have the temperature threshold at 50 degrees set on the fan i also want to do the same thing while overclocking the raspberry pi 4 cpu and i'm also going to test this with the fan on all time overclocked so it's going to take a little while but i'll get that chart made up and be back in one sec all right so after a lot of testing here i'm back with the results through all of these tests room temperature was 74 degrees fahrenheit or 23.33 degrees celsius in orange we have a 2.1 gigahertz overclock with a fan always on we hit a maximum of 65 degrees celsius which is way under that thermal threshold in blue we're still overclocked to 2.1 gigahertz and the fan comes on at 50 degrees celsius only hit a maximum of 65 degrees celsius there and finally stock clocks 1.5 gigahertz with the fan coming on at 50 degrees celsius we get a max temp of 58. it does a great job even overclocked to 2.1 gigahertz and i really do think this is worth 10 to 11 depending on where you pick it up from so yeah that's gonna wrap it up for this video really appreciate you watching i'm a big fan of the poly plus from argon one it's a decent little case coming in at 10 to 11 it does have that heat sink with pwm fan control and overall it does a great job housing the raspberry pi 4 and keeping it cool even overclocked to 2.1 gigahertz if you're interested in picking one of these up i will leave a few links in the description but if you already have a case that you really like using and you think you may be able to fit this fan in there you can actually just pick up the fan itself for five dollars and this should fit in the official raspberry pi case and if you're not into using a case at all you can just slap this on the top of the raspberry pi and keep it cool that way but that's going to wrap it up for this one if you have any questions let me know in the comments below and like always thanks for watching youhey what's going on guys this eta prime back here again today we're
