GeeekPi Case for Raspberry Pi 4, Pi 4 Fan ABS Case with PWM Cooling Fan 40X40X10mm and 4pcs Heatsinks for Raspberry Pi 4 Model B (Black with Large Fan)

This case is a real bargain. It is nicely made out of ABS and it is clear the manufacturer cared. In the two packages where 4 screws were needed there were 5. The fan is very quiet and has the 3rd wire so it can be controlled. Works very well. I used it a CM4 mounted on a Waveshare Compute Module 4 to Raspberry Pi 4 Adapter and had to make two very small mods to get it to fit. A little notch for the boot switch and about of millimeter of clearance need to made for the USB C adapter. Less than 5 minutes work.

Very solid and well built case. Easy access to the internal connectors and gpio pins. It also includes a heatsink for the USB chip, something a lot of other cases do not. Be aware that the hdmi ports are set slightly back and are not flush with the case. Some hdmi cables will not work because the tip is too small (see picture). The Phillips cable works. The adapter is too short. You can shave back the plastic on the connector to expose more of the tip or make the opening in the case larger. The negative black connector from the fan (see picture) needs to bent slightly because of an obstruction from the case.

My Raspberry Pi 4 was nearing the thermal threshold (80C) when using the standard plastic case, which does not have a fan. So I was looking for a case that provided good airflow to help with cooling. This case does the job very well, stabilizing the CPU temperature at around 62C under 100% CPU utilization. Some things I noticed about this case: - The fan pulls cool air down from above the case and blows it directly on the Pi board. This was not as shown in the product description pictures, as I expected it to suck hot air up out of the case. However this arrangement seems to be working fine. Warning to those of you who like to stack your Pi cases: leave enough gap (1-2cm) above this case to allow sufficient airflow. - The fan has the option of running at high speed (5v, GPIO pin 2) or low speed (3.3v GPIO pin 1). Running the fan at high speed produces the best cooling but there's an audible whine that becomes annoying if the Pi is near your work area. I'm currently running the fan at 3.3v low speed which is completely silent. - Some reviewers have noted that the case interferes with connecting the fan ground jumper wire to GPIO pin 6. This is true, but there are 7 other ground pins to pick from. I recommend using pin 9 for ground instead. - I had no problem connecting the mini-HDMI or USB-C cables to the ports. There seems to be plenty of clearance built into the case. All in all this is a great case for your Raspberry Pi 4. It's also a great value at around $10.

I bought a different case with my Pi 4 that was pretty terrible; it had a hole over the GPIO pins so huge that you might as well not even have a case at all. And the fan it came with was dismal, horribly whiny and nasty-sounding, and started to fail within a couple months of install. This case is much tighter; the lid has a small gap on the side to let you get GPIO wires through, but not so much that it compromises the case. And this fan is nice and quiet and moves a lot of air. Further, it's a standard size, so if it does fail, it's easy to replace just the fan, without having to buy a new case. I quite like this design. Good outfit.

I have owned many Raspberry Pis, from the original model B to the current 4, both Zeros, and a variety of corresponding cases. This one is as pretty as some of the Acrylic cases meant for public display but it is solid, well constructed, easy to assemble, and still manages to be attractive. Excellent product and I will buy again!

Overall, the case is fine. But I'll look for a different case for my next project. The wall of the case is too thick to allow the HDMI connector to fit without modification. Additionally, while assembling the case I ran into a problem. The fan wires (black and red) that connect to the GPIO header interfere with the case. Inside of the case, there are bump outs that allow the top section to connect to the bottom. One of these bump outs sits directly over the 5v and GND pins used by the fan. I connected the fan before attaching the top and bottom sections. While trying to attach the two, I crimped the fan wires. Not a deal breaker, but seems like something that was overlooked and is easily fixed on future models.

This case is great. I really like the minimal black design. The top cover allows for access to GPIO and other connections if needed. The included fan is quite on both 5v and 3.3v power. I only wish it was a little taller to accommodate both the fan and a Power over Ethernet (PoE) hat. I realize most users won't be using PoE so I still feel it's 5 stars. With a hat + fan the cover is just a few millimeters from being able to snap closed.

I love these cases. However I was not expecting the fan to be so large. It hits the time chip. And im going tio have to modify the time chip so it can fit under the fan

This is a all round great case, assembling it didnt take long, came with all the pieces, tools and extra hardware in case you lose one. The only issue I had was that the case was a little hard to close (snap shut) and the fan is a little louder than I would have liked. All in all great case for air flow and keeps my raspberry pi at a good temp.

A very smart looking case, compact and clean. Even came with spare screws. The fan is quiet as advertised, obviously isn't completely quiet as is any fan. I don't need the case for the fan, the PI has proven to run under super hot conditions under the hot Aussie sun in an enclosed waterproof box, got very hot, melted the 3D printed case I had in there, so this fan is there to help it run better under heat. Overall, very satisfied.

Perfect fit and well cooling

Not too much to say other than I like it. It's a great little case that snaps together well and holds snugly, and the fan keeps a Pi4 cool with minimal noise. I bought two for two different applications both with highly-loaded Pis and they keep them cool and protected. Would definitely recommend and if I get more Pi4s in the future, another of these cases will be bought with it!

Overall this case is quite nice. The biggest drawback is the case is made of three parts and they very easily separate. If you pick it up by anything but the bottom the middle or upper portion will separate. For a tiny bit of plastic to make a better clip OR better yet, a coupe of screws to hold things together that was a let down. The fan is really quiet and does a great job. The heat sinks fit well and once assembled the case looks nice and does what it's supposed to. As long as you don't want to move your raspberry pi around it's all good. Update: Contacted GeekPi about the case and they sent me a new one. Fantastic service.
