Geekworm N300 Heatsink Case for Raspberry Pi 4, CNC Ultra-Thin Aluminum Alloy Metal Passive Cooling Case Compatible with Raspberry Pi 4 Model B Only

I love the fit and finish of this case! And it does a great job of keeping everything cool as well! It is very well built and was a breeze to assemble.

The Rpi4 is incredibly versatile and portable so a sturdy case to keep it tidy and safe is important. This case is durable, well designed, and effective. The case does get quite hot under load which informs me the heat sink is functional, the thermal pad is a nice touch. Because the case has a considerable mass relative to the Pi it offers plenty of surface area for cooling. Because the feet are low profile and the bulk of the heat is on the underside, the surface you place the pi on is something to consider. A glass table top or granite counter for example help sink heat further and it is possible to locate the pi for better airflow.To make a complete setup I added two HDMI pigtail adapters and a rather handy 8-35v to 5v 3A USB-C power supply.I added the Anderson power pole connector to the power supply to function from my car or off a portable power source. I was pleased to discover the two mounting tabs on this power supply will mount using the included case screws if you put two small extenders on. This makes for a complete ready-to-go package through the supply does cover some of the pinouts which on one hand keeps them safe, but on the other precludes their use. For an all-in-one portable computer, the package is ideal.The Amazon link for the power supply if you are interested: https://www.amazon.com/HOMREE-Step-Down-Converter-Module-Charger/dp/B07ZQB6S3L/ref=pd_rhf_dp_s_rp_c_2_4/138-3541069-5278503?pd_rd_w=UJBul&pf_rd_p=b84519b4-0dcf-432b-8d9a-2d8045a876e9&pf_rd_r=MXBF7P8DTQNXCQTNBNZ3&pd_rd_r=1ae8c705-f1ab-4f35-b44b-0d5279e37a48&pd_rd_wg=MEykr&pd_rd_i=B07ZQB6S3L&psc=1

Fits the pi4 perfectly. Very compact and slim design that comes with high quality thermal pads and fitment. Great thermal dissipation and thoughtful design for small spaces. Keeps the pie4 thermals/temperatures in check as well with very good thermal dissipation.

Without a doubt, this was designed to meet and exceed all the major functions of a case for the Raspberry Pi 4.• Protection: Solid. The aluminum-alloy body is no joke. You could probably drive a car over it and not damage the Pi (just keep the tires off the exposed USB ports.)• Passive-cooling: No issues here. I would only echo other reviewers' criticisms on the instructions for thermal pad placement. The images on the Amazon listing page clearly shows how to cut and place one thermal pad.The images also show that there is another thermal pad strip that is included in the kit. You're on your own with these. Do what you think is most logical.The last image on the Amazon listing page are the same instructions that come with the product, so you can see what I mean.• Accessibility: The product images tell you everything you need to know. Full access.• Appearance: Elegant. This is one of those products where form and function converge on unity. It's minimalistic without sacrificing utility. It immediately impresses people who appreciate the subtle intent that's evident in good design.My only issue is with the adhesive on the rubber feet. They will fall off without much force. If you choose to attach them, I highly suggest supplementing with a durable adhesive of your choice. The feet are clear, so choose wisely if you want it to still look pretty.

Overall this case is actually an excellent design. However, there are two (possibly three) complaints I have:First, it is not designed to support active cooling at all. There is nowhere a fan could be mounted and it is the bottom (which is likely sitting on a surface) with the radiator part of the design. If you're using a RPi4 in a normal manner it should have an equilibrium temperature well within a safe range, but if you do any sort of overclocking or heavy usage it can begin to go up a bit higher than is ideal for maximum long term use. (In my own testing it never at all approached thermal throttling temperatures. This was in a room that stays at a fairly optimal temperature and good airflow however, and in less ideal conditions it may reach a much higher equilibrium.)Second, the choice to put the radiator fins on the bottom is a design choice that reduces its effectiveness in many ways. On the one hand, the reason the top is flat is because it's designed to be able to handle a HAT, but on the other, the top is the portion that directly contacts the CPU and RAM chips -- not the bottom -- so heat must dissipate much less efficiently from one side to the other. This is also troublesome because the bottom can sit fairly flat on a surface and may also suffer lack of airflow due to this (though they offer rubber feet to put on the bottom which at least raise them a millimeter or two.) I do believe the top still could have had at least some slight indentations to give it a bit more ability to dissipate directly. That wouldn't be as effective as full ridges, but still would be an improvement. I do wish they had at least accommodated the possibility of a fan with a place to mount one or something (no need to include one since they can be bought separately, just mount holes over some holes or raised area.) It's possible to mount it somewhere further away from a surface -- in fact it has mount screw holes on the bottom -- and even to place an external fan, but this does complicated overall design considerably. I did add a couple of short heatsinks to the top since I don't plan to use a HAT right now and it does seem to have helped considerably, but without active cooling it still can get fairly warm. Nowhere near to thermal throttling temperatures under normal conditions however. I didn't have sufficient time to test maximum temperature under constant stress, but of what I did test it didn't exceed 60C during the hour or so I was able to continuously stress it. You're unlikely to ever want to use this for factoring or folding or something (far less efficient than a good CL-accelerated design) so I do think that a full stress test isn't indicative of normal use even with overclocking.I may have a third complaint in that I think it is affecting WiFi stability, however, this has not been thoroughly tested and verified yet (I'm primarily using ethernet.) It is anecdotal, but the RPi in it has been having considerably worse WiFi performance and reliability since installing it. However, since it's not tested much and it is overclocked I can't confirm that at this time.All the rest I have to say about it is entirely positive however. The design *IS* overall a really good one. The radiator fins on the bottom are thorough enough to allow a fair bit of heat dissipation. The entire enclosure makes good contact with itself too. Most of these metal enclosures barely actually connect the top and the bottom directly. Typically they sit on either end of the RPi's PCB, not extending past the board so the only actual thermal communication between one end an the other are the screws holding the two sides together. Since the metal of the top and the metal of the bottom are directly in contact with each other the efficiency in transferring heat from the top to the bottom is far higher (thus the whole thing is a heatsink instead of just the top part as with most metal enclosures.) I took things a step further by putting a very tiny amount of thermal paste between the two and feel like it is exceptionally effective, though I wouldn't say this is strictly necessary.Also, my favorite part of this is it is a true enclosure while still being extremely minimal. It barely extends past the PCB, but does still do so. This protects the RPi itself from many things, but also, more importantly, the connectors are seated tightly in the enclosure. This makes it nearly impossible to push one up too hard and pull it loose from the board (yes, I've seen it happen.) I do believe it should protect the RPi itself from practically anything (although the USB and ethernet ports would be vulnerable to something really extreme.) I think not many people are running cars over their RPis however, so this likely covers most realistic scenarios.Overall this is definitely a great case. I can absolutely recommend it if you're using external WiFi or ethernet, but more testing is needed if using the internal WiFi.

This was the best addition to my Pi4. It's keeping my Pi operating without overheating and NO annoying fan noise. This is the best enclosure for a pihole to run in a corner and to be forgotten.

La carcasa oficial del rpi4 era terrible, ya que necesitaba acceso al puerto GPIO con mis otros módulos. Pero esta carcasa le quedó genial a mi rpi.

I bought this case for the passive cooling since it is much slimmer than other cases and doesn't require the additional bulk of heat sinks or cooling fans. Time will tell, but so far so good.

He comprado la funda para una raspberry pi que llevo comnigo siempre. Ya que yo utilizo macOs en mi día a día, a veces es útil tener un sistema con linux a la mano. Desde que tengo la funda no me tengo que preocupar por la temperatura o el ser extra cuidadoso con cargar mi pi, simplemente la puedo echar a la mochila con el resto de las cosas y usarla cuando es necesaria.

I've bought this case in hope it will do a good job, and it does. I needed a passive cooling solution that would accept a HAT on top of it and was slim. it works perfect, and you can see that it makes good contact on the thermal pads. Also, there are holes on the bottom so you can mount it on a plate. it will stay far from thermal throttle in normal use. Wifi suffers a bit (1 bar less), but it's ok if it is oriented towards the rooter.Stress test : "stress-ng -c 4" with ambiant temperature of 22°CWith canakit heatsink : 83°C after 1 hour and still ramping upWith this heatsink case : 57°C after 1 hour and stabilizedWith canakit heatsink and fan : 52°C after 1 hour, but not viable for longtime use because of fan failure.

The included thermal pads make poor contact when the case is screwed together. I replaced the thin pads on top with thicker pads to prevent overheating.
