  • Raspberry Pi 4B cooling solutions and sysbench stress tests, including running the Pi 4 in its official case, in a Pimoroni Coupe case with a heat sink, and with a 40mm Noctua fan in a custom, 3D printed mount.
    My “Online 3D printing” video (in which I show how I created the 3D printed parts used in this video) is here: • Online 3D Printing: Ti...
    The USB host controller firmware upgrade that will reduce the temperature of a Pi 4 by a few degrees can be accessed via: www.raspberrypi.org/forums/vi...
    The Pi 4 Pibow Coupe 4 case is here:
    shop.pimoroni.com/products/pi...
    And the Pimoronic 40x30x5mm heat sink is here:
    shop.pimoroni.com/products/ra...
    The Noctua NF-A4x20, 40x20mm 5V fan can be found on Amazon.com here amzn.to/2l6A0Y6 -- and on Amazon.co.uk here: www.amazon.co.uk/dp/B071W6JZV... (affiliate links).
    Potential M.2 SSD heat sinks can be found on Amazon.com here amzn.to/2xJ6CKq -- and on Amazon.co.uk here: www.amazon.co.uk/dp/B07KXSK13...
    (affiliate links). But do shop around for the best alternatives. You will need a hacksaw to cut these to size.
    The STL files for my 3D printable mount can be found on Thingiverse here:
    www.thingiverse.com/thing:374...
    You can also access also alter the CAD on Tinkercad - the top is here: www.tinkercad.com/things/5oV1... and base here: www.tinkercad.com/things/0yoT... Or go to www.tinkercad.com/ and search for explainingcomputers. Do note that you want the Pi 4B top, not the Pi 1B 2B 3B top. :)
    To put everything together, you will need 4 x M2 25mm bolts an 4x M2 nuts to fix the Pi in the mount (or 20mm bolts if you just use the top portion), as well as 4 x M3 15mm (or longer) bolts and 4 x M3 nuts to position the fan (well, you could get away with just two nuts and bolts).
    To power a Noctua fan, you will also need to wire up two jumper leads to plug into the Pi. I personally often buy a pack like this: shop.pimoroni.com/products/ju... and then cut them up as required in different projects.

      ExplainingComputers I love this simple 3D printed case & cooling solution, but am always concerned with the extra height that having the fan on top, causes. I would be very interested in a solution that had the fan positioned at the SD-card end, either pushing or pulling air over the heatsinks (I’ve always wondered which direction was better... an idea for a quick video?). Also, with the ability to create sexy compound curves using 3D printing, I reckon you could induce an awesome airflow, over the heatsinks, & through the fan, with some fancy “ported” baffles (something only an engine head porter could dream of czcams.com/video/iejDWSQEsqI/video.html). I’d DIY, but my arms don’t work and typing this with my thumb is about all I’m up to.

    Since many have asked in the comments what the results would be with official case open but without heatsink, I decided to test it. Installed newest Raspbian to SD card, put my Pi 4 4GB to official case but removed the top part and ran the same test script.
    Here are the results:
    temp=65.0'C
    temp=81.0'C
    temp=82.0'C
    temp=81.0'C
    temp=82.0'C
    temp=81.0'C
    temp=82.0'C
    temp=81.0'C
    Test took 12 minutes and 55 seconds to finish, so 2 minutes longer than with heatsink. Ambient temperature room tempeerature was about 26 degrees but Pi was on the floor where it was perhaps few degrees cooler.

  • @parrotraiser6541
    @parrotraiser6541 Před 5 lety +40

    The Pi Foundation may come to regret the "official" case for the Pi 4. That temperature profile's asking for hardware problems, not to mention the performance hit. At the very least, they should have provided ventilation holes in the top, and possibly a slot (maybe a knock-out) over the GPIO pins.
    An interesting experiment might be a copper block the size of the SoC, tall enough to reach the top of the ports, connected to a copper mesh the size of the board; the idea being to get convection flow. Might cause wifi problems though, if it acts as a Faraday cage. Copper mesh is commercially available online, but the block might be hard to find.

    Great ! This is the video that is so important for users of this new SBC ! Going back to the Pi 3B and 3B+, at least a heatsink if not an active cooling solution IS needed for real-time activities such as SDR ( software-defined radio ), which I run on a 3B. Quite often without a heatsink, the SBC "stutters" ( cuts out for part of a second ) , or "goes into the red" as regards overheating. So YES, your previous "active-cooling" work HAS been very valuable in those situations. Your final solution with the Pi 4 is obviously the one to go for, for anyone doing more than the most basic work - people dreaming of running two HDMI screens, and using the Pi for streaming video, or indeed SDR as I do, really need to opt for you final solution to "stay cool". Overheating reduces the life of any computer systems, and throughout me career over 30 years in the computer industry, cooling was a mandatory part of computer installations. It certainly needs to be with the Pi 4B. What worries me is the number of school classrooms who will be installing these SBCs over the school holidays. I just HOPE that the installers will install then with active cooling systems. Children have very sensitive hands as compared to adults, and we don't want children burned by the heat, especially when they take the lids off the SBCs, as children are prone to do. Thanks for this very valuable video, Chris, and please ALL educators take note of Chris's findings !

    July 21, 2019 - Great COOL tech video, Chris. In electrical engineering classes, we spent a great deal of time about heat management of solid state devices (and nearby passive devices too, such as power resistors). I think today's tech does a near lousy job of moving hot air through earphone jack holes and speaker holes. When using a heat sink, it is also important to provide cool air across the heat sink fins. And then channel the heat flow out. Motorcycle engines do this very well. A coat of paint on the fins degrades a heat sink dramatically. Your new vid proves a basic yet overlooked point: Manage the pathway of semi-conductor produced heat. Details matter. Thank you, Chris!

    Very cool Chris, thanks! My only objection is: During the 2nd test (when you first added the heat sink), was the improved result due to the added heat sink or due to the increased ventilation? You changed two parameters at once, so it's difficult to say which had the biggest effect. Would it be possible to include results from running a bare Pi4 out of the case first, before adding the heat sink?

The heat load should be slower to build, as you have a bigger slab of metal to absorb heat but after that things will level out. In a more real world situation you would probably use heat pipes to move the heat from the heatsink to outside the case where it might get some convection heat transfer (because of breeze) but still be technically passive. Kit's can be bought on eBay although they aren't that cheap to the extent the Noctua would be a better choice cost wise at the introduction of moving parts and energy costs.

    • @voltavidTony
      @voltavidTony Před 4 lety +3

      The reason for not putting a heatsink on while in the case is because that would only delay the inevitable. Without ventilation, the heat has nowhere to go, so adding the heatsink will only provide a slightly larger "space" for the heat to go.
      Of course, a heatsink is always better than no heatsink, simply because it makes for a thermal buffer that will smooth out the heat generated by spikes in power usage. This is the same for M.2 drives and RAM; the heatsink is not primarily for cooling, but for thermal buffering.
      And of course with the amount of power that the Pi 4 draws you'd want active cooling anyways, such as the S2Pi ice tower

    From your tests we can say that almost no throttling occours already with passive heatsink (11mins vs 10 mins) and that minimal heatsink is already effective as the big one. Considered that modern silicon is typically designed for working reliably (10+ years) at 100+ degrees it means that a minimal passive heatsink is already doing the job (well maybe it's better saying it's now mandatory to have it) and active cooling is only for having low temperatures for paranoids...

      -------------------------
      (Ambient) 24.4'C
      47.0'C
      56.0'C
      58.0'C

      I also ran it 3 times back to back (without any cool down period) and the case seems to reach steady state (dissipate heat as fast as the SOC can create it) at 68.0'C (at 24.4'C ambient at least).

  • @hparad51
    @hparad51 Před 5 lety +2

    Chris, Just commented yesterday, have 3 more thoughts
    1. Best cooling solution is always creating less heat, another firmware update like the USB controller.
    2. With a fan solution, even a smaller one, millions of creative users and companies out there designing/using "hats", will require a 4" (sorry 10 cm) connector extension and a huge case. Ideally the case should provide independent air intake and exhaust so its not just recirculating hot air.
    3. If the PCB was designed with the SoC on the bottom side there would be no obstruction from adjacent components so you could cool passively with a copper or aluminum plate the full size of the PCB using the 4 mounting holes, and yes, your feet or some spacer. This would mess with the classic case design but could eliminate 1 of the 2 case pieces.

By now my home automation system has outgrown the 1GB RAM limit and I had started to look at other SBCs with more RAM (like the up board). Then, just at the right time, the Pi 4 with 4GB RAM was launched. I ordered mine within minutes of the launch and have spent the last couple of weeks trying to figure out how to get it to run cool enough to to replace the 3B+ of my live system.

    I always felt that cooling would be an issue for SBC's but it opens up a massive avenue for testing and getting the best out of them with overclocking and cooling projects. What would've been nice to see would have been some thermal imaging shots from the first test to show surface heat and a thermometer to show the real world temperature within close proximity of the board.
    It's always nice to see projects like this as factual data is something that can appreciated on many levels and expanded on until someone reaches the ACME stage of Pi cooling!

    Raspberry Pi Trading has been very diligently deleting my comments on their social media, so I'll try here.
    The Pi 4 overheats and throttles in the official case while just idling at desktop. Yeah, you read that right. I connected it to a 4k display, booted it up and deliberately did absolutely nothing, just left it siting at desktop. In an hour the temperature reached 81 °C and it started throttling. Ambient temperature was 18 °C. It went 63 °C over ambient by just idling! Maybe I'm old-fashioned, but to me that is completely unacceptable for an official accessory.
    I have to wonder if anyone at RPT even looked at a prototype of the case before greenlighting mass production, because this design flaw is pretty much impossible to miss.

    It's too bad someone at the Pi foundation didn't think ahead on this one, and put a nice *slim* fan in the "official" case. There's *just* enough room to mount a small one flush if there's no heatsink, or surface mount if one is present. And if a good fan was chosen, no heatsink would be needed anyway. One caveat.... Yes, the case would cost more. But I don't believe that would matter. If I were buying a Pi4B I'd be wanting a fan-based cooling solution anyway.

      Pi4 SoC got ready almost one year ahead of schedule. I can only imagine the foundation chose to rush things up, in order to reduce time to market. Even so, one can barely use it with official casing. Also, if a company advertises dual monitor 4k 60fps capabilities, and then explains that only works for desktop, it looks like gross misleading. That's not cool, that's not right. If codecs are not ready at deploy time, than the board is not capable yet. It should _not_ be announced otherwise.
