Raspberry Pi 4 Model B Aluminum Case with Dual Cooling Fan

Using this as a local NAS, with a 500gb chip in a USB socket and a 6tb external drive connected. Running Samba so the MS boxes can map drives. The case is fine. Fans are quiet for now. I'm not over clocking the Pi, so heat really isn't a problem. This seems like a good choice.

Works great

This is a well-made, quite durable, nicely-designed and finished aluminum case/heat sink for the RPI that fits perfectly... except that the opening for the GPIO pins is rounded on the inside, and little too narrow to accept a standard 40 pin ribbon cable connector (53.6mm wide vs 55.5mm). I haven't decided whether to grind the opening a little wider (and uglify it in the process), or to try trimming the connector a little narrower (and potentially have it fall to pieces).

Perfect fit. Very quiet. Great solution for keeping my Pi from burning up.

drops temps significantly on rpi4 and makes little to no noise. A+ product.

Works great, very quiet and keeps the RPi cool. However, the hole in the casting over the four-pin header behind the network jack is too small to allow access to the headers. Any expansion hat, like a PoE adapter, that requires access to those pins will not work with this item.

I installed this on my Raspberry Pi 4, and it fit perfectly. I just need to figure out how to mount it inside the case I'm using (original NES case, so this will easily fit inside, room wise)

Worth it

no problem good and best of my orders no bad review used it 24/7 non stop with room temp 22 no problem will see this summer haw much i cam run it.... thanks

Managed to reduce heat on my pi

No issues with installation and the fans are doing a good job keeping the pi 4 cool.

Great heatsink. Comes with the thermal pads. Easy to install. Comes with tools needed. Mind there are two types of style to the screws. There are 4 of one kind for the heat sink then 8 of the other for fans. All screws are the same thread and work anywhere but the looks get skewed if you don't pay attention. Temps peak at 42c under 100% load. Settles at 39c. (Tested in a 3d printer.) The airflow channels under the fans seems a little bit restrictive but the fans aren't overly forceful either so I'm considering placing it in my milling machine and cutting additional airflow channels under the fans to improve airflow for enclosed environments.

This is to be used with a RPi4 running Freeswitch PBX software which is a medium processor intensive program. Thus keeping CPU temperature down is important for reliability. This fan does that. One point I did have trouble with is the included self-adhesive heatt conductive pads. These are quite thin (good) but the peel off strips protecting the adhesive are difficult to separate and I did tear one of the pads in the process. However sufficient pad was saved to stick to the appropriate chip case. I will probably buy this again.
