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 purchased a few of these because I really liked this design for the rPi3 but after an hour of troubleshooting a "no video" issue I discovered that this case was prohibiting the insertion of my HDMI adapter. I have no such problem with my metal cases. I'm disappointed that I will have to delegate these to headless units (or try to find longer HDMI ports). Apart from this I do love the case design and many report that their HDMI plug is long enough, unlike mine. They really should have made the plastic thinner in the HDMI location, and possibly by the USB power.

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!

Quiet and it eliminated the overheating on my Raspberry Pi 4. The only issue is with the power connection to the pi board. The connectors are a little longer than needed, which put a sharper bend in the wire than I prefer.

very poor instructions. the video is too fast. i sticked all heatsinks and the final step is to put the fan part. it will not click to stay put. the holes are closed so it wont click. i am going to put a tape and use it as i hate to return stuff. i will update my review after using it
