Dope Tech Episode 2

<<@afsallais9825 says : 8:26 fan resonates the case. I have noticed the same with my 3b case. I just implemented pwm modulation for the so its much bearable now.>> <<@justj2729 says : Love the data, showing the script and charts. Makes figuring out how I want to cool my Pi5 easy!>> <<@tutacat says : The Pi is heavier. The fan connected directly to the plastic case, which is much lighter, will vibrate more with less energy>> <<@eukaryote0 says : Thank you for your videos. I really enjoy their usefulness and old-school cool vibe.>> <<@Matko801 says : the active cooler aint even avaible in my country>> <<@tibrez says : Fans have moving parts that can break, solid aliminium cases have baically limitless lifespann and ZERO noise. I can trade off a few degress to have that.>> <<@albl2171 says : the THINNER the thermal pads, the BETTER! thicker pads are worse, they can warm the chip way more up. even worse than thicker pads is just if theres still air between Chip/pad or pad/heatsink.... also, aluminium is usually better if there is no active cooling, while copper is better with an active cooler.>> <<@Danefallis2004 says : What about drilling small holes (1/16th) through the lid around the perimeter for better lid ventilation for the pi 5 case?>> <<@schrodingerscat1863 says : I found a passive heatsink for the PI which was decent on it's own but then added my own fan and it runs very cool though you wouldn't be able use a hat with it. Have 2 PI 5s running with this setup in a 1U rack case and they both run very cool and the fans hardly ever turn on and never ramp up to audible level.>> <<@quincy1048 says : how timely...I just got my pi5 and official case with small heatsink and fan, and yea it's good enough not to throttle, but for $10 I think I am going to swap it.>> <<@user-gh1js9im1g says : Thanks for the extensive graph>> <<@venturer-r4p says : Thank you for this video! This helped me check and confirm that the thermals are as expected on my Pi 5 (I used your same script to check the temps).>> <<@brucehanson4147 says : Chris, have you ever tested wifi and Bluetooth performance after installing big heatsinks or metal cases? Having pis that run automation and monitoring 24/7 I prefer passive coolers. No matter how clean the environment, fan cooled units collect a lot of dust plus you are at the mercy of a mechanical fan that can fail. I love the big heatsink case but usually use a large top mounted heatsink so the pi can still be mounted with other controls and power supplies. Trouble I have is these big passive heatsinks kill wifi performance if they're very far from the router so I typically end up running a network cable which is more work and adds clutter. Not a fan of wifi dongles to be able to add an external antennae. Anybody ever added an antennae connector to a pi5? if so, how did it work out? Would love to be able to mount these in a metal enclosure.>> <<@Marttyii says : I feel like Raspberry Pi should learn one thing from Geeek Pi, using screws instead of the plastic spring pins. If you ever wanted to change your cooler or it broke and you need a new one, you can't without breaking the Pi with the pins. Screws on the other hand can be removed and be changed. I do find that it is annyoing that the other ports are blocked by the heatsink case, but there's some other case or cooling alternatives that Geeek Pi or other companies have.>> <<@peterloader974 says : Why not compare using a heatsink with two fans?>> <<@wizzardrincewind9458 says : 👍🖖>> <<@deadevil_fst says : I used the heat sink and have a air conditioner which cools the pi significantly it doesn't go above 40 degree>> <<@zazugee says : 8:50 actually it's really true, if you put your hand on the case while the case fan is running you feel it vibrate alot. also i'm surprised the case fan and the small heat sink do as much cooling as the active cooler, honestly i never expected it did that good.>> <<@themydnighthour says : Interestingly enough, when I run the official case and fan with no heatsink (took them off to use the Argon40, didn't work) the temp is similar to yours with the top off. Am debating to get the active cooler or not.>> <<@DigiKidsChennai says : Thank you so o much, I was looking for the answer of i can use it with active cooler. And got bonus heat test. 🎉>> <<@devangtyagi9870 says : What was your room temperature around when you were performing these tests?>> <<@Bobzwik says : Thanks for this test! You're the only one I found thermal testing the RPi5 with a regular small heatsink and fan. Trying to find ways to shave weight for a CM5 on a drone. Smaller heatsink helps a lot!>> <<@1batman-gameplay says : My raspberry pi 5 have a solid red light and will not turning on I just got it for Christmas can anyone help me please>> <<@pixelbabygamer says : Great products>> <<@WR3ND says : The somewhat bigger brother of this case, the GeeekPi Armor V5 is quite good at passive cooling. I overclocked my Pi 5 to 3GHz CPU and 1GHz GPU at 1V and have had it running a stress test (stress -c 4) for 24 hours to fully load it. It topped out at about 81C and is averaging about 76C with an ambient air temperature of about 20C in a well ventilated area, all without any faults/crashes or throttling! It should handle normal workloads without any issues. Cheers.>> <<@WR3ND says : One of my favorite classic PBS shows. Thanks.>> <<@johnbeer4963 says : Meeting Allen The Key caused Me far more joy than most things on Youtube ever have>> <<@damiandanev9271 says : Bruh... on a couple of your measurements, you dont reach a stable temp. The values keep increasing and would've gone higher had you not stopped testing. Which makes this test inaccurate. How did you not see this?>> <<@nicklane5896 says : Another very effective solution is the geeekpi passive case + a fan.>> <<@KetilHommeLinde says : Very nice test with interesting results :-)>> <<@orfeous says : Please try the Waveshare Poe Hat G and the official case.>> <<@georgekokotis5732 says : Thank you so much! An important question: Did you might record or estimate from date and time the video was filmed, the ambient air temperature? Chris, with own case and the lid on, there is definitely going to be a lot more aerodynamic noise due to local air acceleration that is caused by the air blockage of the lid in the suction side. Also, in theory, the black official case should have a small advantage due to increased radiative cooling>> <<@LiangQi says : Bought a PIMORONI NVMe Base for Raspberry Pi 5, but didn't find good solution for case yet.>> <<@SauceyRedHN says : I don't usually leave comments on videos like this because the comment section is usually filled with very formal and basic comments, which I personally cringe at a bit, but I really just gotta thank you for this video. Been wanting a Raspberry Pi to play around with since last year and today I was like "why not?" Figured out all the things I wanted but wasn't sure if the official case was compatible with the active cooler (which I assumed was the best cooling option). So thanks for the help! Simple, to the point video, which is what I consider the best for just answering a simple question like "which of these products is the best?">> <<@bhagyanaresh says : good work>> <<@yapayzeka says : this is science. thank you very much.>> <<@newkfromrotterdam says : what about those heat-sink cases WITH a fan?>> <<@willmil11 says : Thanks now i'll take off the top of the case :)>> <<@PapaLeech says : So the official case is the better cooling solution with the top on? Interesting>> <<@pinobarbareschi6452 says : hi brother I purchased an Active Cooler pi 5 and I wanted to know if the fan activates automatically at high temperatures, do I need a script? A thousand thanks>> <<@williscoleman9124 says : good videos.>> <<@thewifiangel says : I was worried my Pi5 case (a FLIRC aluminium case) was very hot, and prompted me to search and find this video. So I ran a similar test, running a simple script to sample the CPU temp every 10 seconds. After 3 hours, the average without the case was 63 deg c. The same test with the case fitted, was 52c! Same running conditions etc. So the case is definitely benefitting my Pi5. Thanks for this vid!>> <<@D0h1000 says : Wait a minute... Your saying that using the (Active Cooler, No Fan, No Case) gets hotter than the (Active Cooler, No Fan, With Case)? That doesn't make sense! How would a plastic covering reduce the temperature? Shouldn't it increase the temp because the air doesnt flow as freely? Please let me know if I should buy it to improve temps on my raspberry pi.>> <<@rustyholt6619 says : all this reconfiguring ,,, you need more pies>> <<@MrBobWareham says : Thank you for your testing it was very interesting, but I do wonder with the all metal heat sink does that affect the Wi-Fi range with all the metal around the Pi? It's a bit like a faraday cage would you think.>> <<@coolParadigmes says : I am a fan of passive cooling Heatsink and I tested my RaspBerry Pi 5 with 100% stress on the 4 CPU for about one hour in two different cases and the results are amazing!>> <<@Randomlyme123 says : I avoid using a case at all. But my yet to be fired up five will have the recomended fan. Keeping these beasts cool is very important ive learned.>> <<@thecaveofthedead says : So useful. Thank you.>> <<@luigiprovencher says : How did you connect do in that script to done like that?>> <<@andresmonteverde says : Hanging on your desktop with all kind of stuff connected the official case wins by flexibility, but in the case of being in an attic providing some service, the passive cooling is the best option to have peace of mind, the less moving parts is always the best! fans are always a headache>>
