Description:
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: https://www.youtube.com/watch?v=NzTsDrepf64

The USB host controller firmware upgrade that will reduce the temperature of a Pi 4 by a few degrees can be accessed via: https://www.raspberrypi.org/forums/viewtopic.php?f=28&t=243500&p=1490467#p1490467

The Pi 4 Pibow Coupe 4 case is here:

And the Pimoronic 40x30x5mm heat sink is here:

The Noctua NF-A4x20, 40x20mm 5V fan can be found on Amazon.com here https://amzn.to/2l6A0Y6 -- and on Amazon.co.uk here: https://www.amazon.co.uk/dp/B071W6JZV8/ref=nosim?tag=explainin-21 (affiliate links).

Potential M.2 SSD heat sinks can be found on Amazon.com here https://amzn.to/2xJ6CKq -- and on Amazon.co.uk here: https://www.amazon.co.uk/dp/B07KXSK13F/ref=nosim?tag=explainin-21
(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:

You can also access also alter the CAD on Tinkercad – the top is here: https://www.tinkercad.com/things/5oV12PMZNHH and base here: https://www.tinkercad.com/things/0yoTBSXYcdz Or go to https://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: https://shop.pimoroni.com/products/jumper-jerky?variant=304797129 and then cut them up as required in different projects.
