Dope Tech Episode 2

<<@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.>> <<@ironingbored 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!>> <<@glenbirbeck4098 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>> <<@TobeyNord says : I tried to contact you on telegram not sure if you saw that or not .>> <<@TobeyNord says : I'm considering using Raspberry pi5 in my car along with mega squirt standalone ECU on M.2 and a 7" dash screen . I'm concerned about when the PI gets hot.>> <<@suou7938 says : Active cooler + official case fits real well. Thank you always for informative videos!>> <<@alysiaandjohnglass says : Will a nvme bottom hat fit in that case?>> <<@Prashant-wj9jk says : Sir create video on raspberry pi 5 with raspberry pi high quality camera with 16 mm telephotolence and microscopic lence>> <<@alexandruzorila7622 says : @ExplainingComputers, @JeffGeerling Hey do you think the top half of the GeeekPi Heatsink Case would fit well with the Pimoroni NVMe Base to get a silent Pi5 with NVMe support?>> <<@DavidRinnan says : I have the official case with the built in fan and it is a nice kit (thumbs up!) suitable for most people for average use. I will consider buying the better fan, I like the better mounting for sure.>> <<@DavidRinnan says : it would actually make sense to get a column displaying the temperature without any heat management.>> <<@kk56910 says : Watched this as the first video from your channel. Instant fan ❤>> <<@vladislavkaras491 says : Thanks for the video!>> <<@pixelsafoison says : If only the raspberry foundation would be so kind to stock my country with a single pi5 8gb ... I even gave the gal that is the official reseller for belgium a call... None planned for delivery, not now, not soon .. So many things that I'd like to experiment onto that SBC, but none of these things would work with 4 gigs.... The next iteration should simply have 0 gigs and a so-dimm slot.>> <<@mirko46381 says : Documents suggest that Active cooler is permanent. They suggest not trying to remove the active cooler since you can easily damage the board. Can you show how you are removing the active cooler, do you cut plastic snap push screws and replace them afterwards or you are using some tool to do the job?>> <<@TrudleR says : So the CPU never got throttled with those low temperatures right? I went for a Geekworm Heavy Duty case, as I had it for my RPi4 already. I don't care it it gets hotter, I just don't want throttling to kick in. I work with my Pi's behind my back. Even if coolers are silent, it would annoy me to hear them start and stop. Also, an active cooler pulls more energy and I wan't to optimize for that. Great video! Love those comparisons!>> <<@meneerjansen00 says : Will the Pi break if it's at 75 C for 24 hrs per day? And how about with the big heat sink @24 h per day? P.S. I liked the simplicity of the orig. Pi. Like you said in one of your vids: a Pi is slowly getting getting too expensive and too much of a hassle compared to a $250 or $300 Chromebook. And they don't sell the old Pi's any-more...>> <<@robertbox5399 says : Why didn't the passive heatsink have further conductive pads on the rear of the board? Modern BGA's put a significant amount of heat down into the PCB.>> <<@gregh.g.83 says : Thanks>> <<@zetaDirective says : @ExplainingComputers - the difference between the fans is one is a blower fan, which should be noisier, but you'll need to check fan RPM, not just temp, in order to see the full picture>> <<@151mcx says : wish you would have ran the geek pi heasink for around a full day, in case someone wanted to use the pi for Distributed Computing (folding@home)... I'd rather have super quiet (no fan to clean or fans to replace). After looking at your results, it would lead me to believe in a few hours, that the pi would be thermal throttling with the GeekPi Case. Personally, I'd rather using an 80MM case fan, like a be quiet fan that runs forever with dual ball bearings (no sleeve bearing)... and is big enough to really move some air without making any noise. Also, you could even get a cool RGB led one if you so fancied. I hate those small fans, in my views, they don't last a long time, they get noisy quick, and good luck finding a replacement.>> <<@lashturner says : My rpi5 doesn't boot. I tried different sd cards and also tried usb drive but as soon as I plug in card it goes dead.>> <<@RucasGomes says : Thank you, very informative>> <<@ronaldhofman1726 says : I have the active cooler and laeve the top open , but removed the original case fan and enlarged the hole in the transparent part and clicked that in also , ther enough room for colling , did not test it , but i will do that to>> <<@spaaarky21 says : Seeing the temps is kind of interesting trivia but all I really care about is thermal throttling. I assume throttling on the Pi 5 still happens in steps, at 80° and 85° like on previous models?>> <<@JBoy340a says : Great content! Do you know of any case that supports an nVME drive within or on the bottom of the enclosure?>> <<@curious968 says : One thing that should be tested with these solutions is the WiFi. I have a very nice Vilross case, but the downside of the massive hunk of aluminum is that it seems to block the WiFi signal or at least weaken it. Don't know about your solution, but given my experience, worth a check in the future. For my uses, losing WiFi is not a big deal (it's hard wired), but in other situations, the official case (modified trivially to accept the active cooler) is an excellent choice even with the cover on because it does not interfere with WiFi.>>
