GeeekPi Armor Lite Active Cooler for Raspberry Pi 4, Aluminum Heatsink with PWM Fan for Raspberry Pi 4 Model B 2GB 4GB 8GB

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

The quality was good, had the tools for installation, and the noise level is great as I expected!

I’m using this with a Raspberry Pi 4B, and overall it does exactly what it’s supposed to. There’s a noticeable improvement in temperature after installing it, so it’s clearly doing a good job at cooling. The fan is also fairly quiet, which is a big plus if you’re running your Pi for long periods (or all the time like me). The only downside is the installation, it’s a bit fiddly, especially when fitting it into a Raspberry Pi 4B case. It’s not impossible, just something to be aware of if you’re expecting a quick, seamless setup. Once it’s in place though, it works reliably and keeps things running cooler without adding much noise.

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!

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!

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

Protect your pi

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

passt und funktioniert super. ultraleise und die Grad kann man auch einstellen (raspi-config) wenn er einschalten soll. Auf der Alu-Kühlplatte sind auch die Höhenunterschiede der zu kühlenden ICs berücksichtigt - perfekt.

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.

Cela fonctionne vraiment parfaitement et le produit est livré complet, avec des instructions courtes, claires et illustrées. J’ai dû adapter légèrement mon boîtier « OneNineDesign », mais cela n’a posé aucun problème. Sur mon Raspberry Pi 4B, j’ai réglé la température maximale à 60 °C et le ventilateur démarre correctement, puis continue de fonctionner jusqu’à ce que la température redescende à 59 °C ou moins. Le graphique dans Domoticz illustre parfaitement ce comportement. Avec la commande "yes > /dev/null" & il est facile de charger un ou plusieurs cœurs du processeur à 100 %. C’est impressionnant de voir que le Raspberry Pi 4B reste parfaitement utilisable même avec 99 % de charge CPU, ce qui permet ensuite d’arrêter les processus avec « top » et « kill ». C’était exactement ce que j’espérais, et grâce au kit complet, ce risque de surchauffe est désormais écarté pour le moment.
