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

I'm really impressed with this little case. My Pi4 was running very hot at around 61C in the Official case, but now I've switched it to this case - it's idling at just below 40C. The fan makes so little noise I barely notice it even when standing next to the Pi - it's definitely quiet! That said, if you planned to sleep 1m away from it, I expect the whirring would be annoying - it's not completely silent and I wasn't expecting it to be!The case was easier to put together than I feared from the instructions requiring just screwing the fan to the lid, and the Pi board to the bottom plate.Now that it's all put together, it looks nice. A bit chunkier than the original case, and a bit more serious looking. I opted for the black version and it looks nice and understated next to my router.My only minor negative comments are:1. I had to come back to Amazon to read where others had put the fan's power cables. I expect they don't include this instruction as some knowledge is expected for Pi owners, some users might want to do different things with the fan, and it's possible the GPIO port layouts could change. All understandable, but as there is a small instruction pamphlet, adding a suggestion for where to connect the fan would be useful for those without knowledge of the pins.2. The lid doesn't make much of a click or any other feedback to let you know it's secured - I thought it wasn't going on properly at first - but then realised it was on firmly!Very happy so far with the 33% reduction in heat in the Pi - whether that's due to the fan or the better ventilation in the case!

First of all, delivery was quick, as you'd expect from Prime delivery.Going onto the actual case: quite simply, I'm very impressed. It's the attention to the small details that won me over. You get the rubber feet for the case; 5 (1 extra) screws to mount the fan; 5 (1 extra) screws to mount the Raspberry Pi to the actual case and a tiny magnetic screwdriver. This was a lot more than I got with the official Raspberry Pi case. It's well made, nice and smooth and looks good.Temperature: down to possibly the most important part. My Raspberry Pi 4 Model B used to idle between 60°-70°, depending on load. Now? It's down to a rock solid 40°. I already had heatsinks installed, but it's nice to have spares.Fan: the only thing that lets down this great value case is unfortunately the fan. Perhaps I didn't get lucky, but even when setting the red power cable to the 3v3 pin, it's audible when in operation - even when standing next to it. I use mine plugged into my router, so it's not a big deal, but I think it would annoy me if I was in the same room as it for prolonged periods of time.Minor improvement: as someone else said, the addition of the pin layout and which pins to connect to in the form of a leaflet or something would have been ideal. I had to look these up separately.

Quite pleased with this.Previous reviews seemed very mixed on the fan. Some said it was loud and they could hear it in the next room when others said it's almost silent. My experience is somewhat in-between, it does make a low-level buzz (even on the 'quiet' 3v mode) that is audible from across the room, but it's so weak that it gets drowned out completely the moment you have any sort of audio playing. So I'd recommend the case for a desktop, media or retro gaming box. But probably not for something like a Pi-hole that's going to be running in a silent room 24/7.Quality-wise it's a nice looking case, the board screws in so it's very solid and doesn't rattle about once put together. The buzzy little fan works well, keeping the CPU at 36.0c during an OS install. Was very easy to put everything together, heat sinks were all the right size and didn't require any cutting of thermal tape.

Nice little case. :) The fan does fall off sometimes but not on its own, only when picking it up and moving it. Easy to put back in place.

Tidy case, very easy to use and assemble.Secure fit for Raspberry PI.Fan and heat sinks easy to put in place and fan can be used as a temperature activated or full time on.Pin listings are clear to connect the fan also.Easy slip on/off roofing for access the the board pins if needed.Great item.

Looks good, and now the fan is quiet and the instructions for plugging the fan connections is clear. Earlier models evidently had a loud fan with no instructions.

Great product for £9, not totally silent so I guess the ideal use case is dependant on location.Mine lives in the cellar for pi-hole DNS + torrents so fine.

Very compact and sleek case. Very easy to put together and the instructions were clear. Got the fan to work very easily too.The only issue is the dust accumulation overtime. Cleaning it regularly is important. Can say for sure that it protects the pi and keeps it from getting hot.One negative aspect was the location of the sd card insertion. When it’s inside the case, it’s very difficult to insert and remove the sd card so I always took the pi out before inserting or removing.
