Raspberry Pi 4 Fan ABS Case with Cooling Fan, Heatsink, Simple Removable Top Cover for Pi 4 Model B/ 4B

This is a very simple case, heatsink, and fan set, but it is well worth the 11 bucks it costs. The Raspberry Pi 4B (RPi) board fits perfectly, and is held securely in place by screws. The fan fits onto the lid well and is hidden once the unit is assembled, and it's several mm larger than other fans I've seen with cases. This makes it more efficient at its job - cooling the RPi. The heat sinks that go on the chips of the board help a lot, too. Before I put my board (which I use as a network packet capture device to troubleshoot my clients' networks with) into this kit, it ran at around at about 65-75 degrees Celsius. With this this kit, it runs closer to 40-45 degrees. My only wish is that I could find a version of this kit that also includes an RPi, a power supply, and a micro-HDMI adapter. I think it would give Canakit a real run for their money! The only downside is that the fan is not silent, but it is still quite quiet.Edit: I originally wrote my review back in September, 2018. It is now February, 2021, and I still love this case! I have 2 of them. I just have a couple of things to add about it.First, this case DOES NOT fit the Raspberry Pi 3B or 3B+ boards without what I would consider serious modification. Those boards have a single full-sized HDMI port, and the network jack is on the left side of the end with it and the USB ports. The 4B has the network jack on the right, with the USB ports shifted to accommodate this change. This change was made to make room for the audio jack to be moved to make room for the 2 Micro HDMI ports on the 4B. These may seem like minor changes, but they really get in the way when trying to fit one board model into a case made for the other model.Second, the reviewer who said the fan wires get in the way of the fan didn't mount his fan correctly. If you install the fan properly, there's no problem whatsoever. My wires are neatly out of the way, and always have been. I did make sure that the fan was mounted in such a way that the wires just neatly route themselves, which required some thought and rotating the fan body to the proper orientation on the lid, but it doesn't take a genius to figure it out. That reviewer simply needs to remove the mounting screws from the fan and rotate it 90 degrees one way or the other (or maybe 180 degrees) and the issue would vanish.

The product is exactly as advertized, but the description leaves out a few features that I think should be noted.First, the kit comes with a total of 10 screws. The build uses 8. Now, extra screws aren't that uncommon, but adding a fifth to sets of four is not something you expect nowadays. It's a really nice touch that they would do that, as simple of an extra as it is.Secondly, the little screwdriver they include for assembly is slightly magnitized. If you drop a screw somewhere, or get it stuck in one of the holes, you can just pull it out with the included screwdriver. Helps a lot for lining them up vertically without worrying about the screw dropping, too.Thirdly, the case is very solid. It's ABS Plastic, but the finish looks as professional as molded plastic can, with no visible deformities and clear resessed lettering. It doesn't flex at all on either axis. Its small size does help it in this regard, as that reduces the resultant moment of torque applied, but still. It's amazing how many people put out an awful junky case, and this case is not one of them.Fourthly, the fan works very well. The bearing is smooth, and it is decent at providing real pressure difference and airflow for its size. It's not magic, it does make a bit of a humming noise and certianly is not 'whisper quiet', but it's not loud or overbearing at all.Fifthly, if you happen to install the fan on backwards, the connector wires are long enough to allow you to easily install it on the fan headers anyway. It's not a tight fit, either, easily doable. Such a small thing to include, but a major fustration saver.And, finally, on my unit, they put a little black sticker over the fan information sticker, because the sticker would normally be pressing up against the grate and be visible against the black case.This is a product where it is very clear that the designers really put user experience as one of their main concerns. I am a mechanical engineer by trade, and I can tell that this is a product that was really, actually designed, not just built to spec. As it is the only Raspberry Pi case I've ever purchased, I can't say for sure that it is the best, highest quality, best looking one at a good price. But I can say it's good looking, high quality, very reasonable for its price and built in such a way that it is clear the designers care about how it will be for a user to assemble the unit and what it will look like when done. They got both beautifully right, and the affordances and thought put into it just made me smile while I assembled it.

I'm quite pleased with this case and would recommend it to anyone that needs an economical active cooled case. The included cooling fan can operate using the 3.3V and 5V GPIO pins for a low and high operating speed respectively. After some minor screw tightness adjustments, the fan runs on high in a way that it is much quieter than the fan add-on on the official red and black Raspberry Pi 4 case. Running at near idle for multiple hours, the CPU and GPU temperatures remained at a nominal 26.284C (79.3F) located in a room that was 20.55 C (69.0 F).The case is solidly constructed and includes screw slots on the under side to allow for wall mounting which was an excellent fit for my use case. For the very reasonable price, this will be my go to case for Pi 4's from now on.
