GeeekPi Raspberry Pi 4 Armor Lite Heatsink with PWM Fan, Raspberry Pi Aluminum Heatsink Cooling Kit With Fan Speed Control for Raspberry Pi 4 Model B

Fits and does the job. It's not to loud either.

CPU set to 2000Mhz & GPU 750Mhz on a Raspberry Pi 4 B On a 4k display the max temp is around 64c and at full HD max is about 61c. This is with the fan set to only come on when the temperature hits 60c so work perfectly as the Raspberry Pi 4 B doesn't throttle until you hit 80c!

Pretty happy with this heatsink. I had some cheap individual heatsink that were working fine with a fan, but then the fan broke and by themself they could not cool the raspberry pi enough. I have a RPI4b with no overclock (old board revision, so 1.5ghz) and with some light load it was hovering around 60-65 degrees, with peaks in the 70s. This heatsink reduced it to around 45-50 degrees with the fan turned off. With the fan on the temperature can easily go down to the mid 30s. The fan itself is a bit noisy, but not too bad. Noise can be further reduced by connecting it to the 3.3v pin instead of the 5v one (it doesn't seem to be officially supported, but I tested it and it works fine). That said I've left it on the 5v pin and just configured it to turn on only above 65 degrees (this is a programmable fan, which is extremely nice) so that I won't have to ear it unless the Pi really need some cool off. Build quality is nice, a nice chunk of (I think) aluminium and some heat pads. The heatsink itself is compact and allows access to the GPIO pins, most other ports on the PI (but might make them a bit more cumbersome) and to place the Pi in a "standard" case (but note that the screws might interfere with the Pi high in the case - a simple fix was to chop off a tiny bit of plastic from my generic case to make the Pi level again). Hopefully the fan itself won't break down in a few months time, otherwise I would suggest this to anyone looking for a small and silent heatsink but with a fan for all situations.

This is an amazing little heatsink and fan. My idle temp used to be 50/60 degrees C... But with this it is now 30! It's really quite and with headphones on or if the device is not out in the open, it cannot be heard at all! Very well made and very easy to install! I have the fan set to just run constantly as I want the heat to be dissipated all the time. But I cannot notice that it is on most of the time, due to the low noise level!

Installed in a NESPi case so the case needed two of its fixings removed but otherwise all good.

It is important to note that Wifi and Bluetooth signal will degrade after installation. Otherwise, the unit reduces CPU temperature by approximatley 15C which is significant.

Muy contento con la compra por calidad y sobretodo por el ventilador silencioso.

L'ho comprato da mettere dentro un cruscotto in una panda prima serie, quindi in estate temperature molto alte. devo dire che questa piccola ventola, non si sente per niente e tiene freddo il processore, che di base non ha veramente bisogno di un dissipatore se usato normalmente, ma se tenuto dentro un'auto cocente, allora ne ha assolutamente bisogno! Viene fornita di piccoli pad termici da mettere sopra il soc e le memorie, ci sono anche le sue piccole viti per fissarlo al Raspberry

GeeekPi Aluminum Heatsink with PWM Controllable Fan for Raspberry Pi 4 (B091L1XKL6) I use them for all my RPi's. They do make a significant difference when needed. This is the best low profile cooling solution for the Raspberry Pi mini PC. The aluminum heatsink works well for absorbing heat. This is a 3 wire fan, so there is PWM control (software or script required for operation), which is perfect for turning the fan on when the device heats up and turning the fan off when it runs cool. One of the best investments for my Raspberry Pi's.

good

Zo stil dat ik me soms afvraag of 'm wel werkt. :-)
