GeeekPi Acrylic Case for Raspberry Pi 4 Model B & Raspberry Pi 3 Model B+, Raspberry Pi Case with Cooling Fan and 7PCS Heatsinks for Raspberry Pi 4 Model B/Pi 3B+/ Pi 3B/ 2B (Brown)

Used for Pi 3 & Pi 4’Would suggest buying some hex spacers if your Pi has a hotspot

I bought this case for my 2GB Pi 4 primarily because of the price and the included cooling fan (there weren't any reviews yet when I ordered). It was easy to put together although some of those tiny nuts were hard to start with my big fingers. I'm very pleased with the results: it look nice and, more importantly, CPU temps were cut about in half, with average temps running in the mid to high 30s now rather than the mid to high 60s. Outstanding improvement, no doubt due to both the fan and the open design of the case.I installed the fan on the inside, there was just enough clearance over the heat sinks, and I have the air blowing in onto the motherboard. Also, I have the fan set on the high setting since it's virtually silent and I want maximum cooling.This is a heck of a deal for nine bucks.

I couldn't be happier with this product. I have a Raspberry Pi 3 B+ and a Raspberry Pi 4 (2GB) so I bought 2x of the cases/fans and noticed a huge difference in CPU temperature. I am running a minecraft server on the RPi 4 and the CPU consistently would reach 80 degrees celsius because I have it overclocked to 1.75 GHz and the GPU to 600 MHz. With the fan the CPU is now in the range of 50-60 degrees celsius consistently which allows the RPi to run quickly and efficiently. Money well spent and I highly recommend the product.NOTE: The fans do not move a large volume of air but it is designed to draw out the warm (almost dormant) air sitting on the cooling fins. This brings the CPU temp down approximately 25 degrees celsius.

Very good product!

Pi 4 sits just under 40 degrees on idle with this case. Lots of tabs opened, all playing 720p videos, temp does not go over 55. The fan is not loud at all.
