Review on 🌬️ GeeekPi Raspberry Pi Cooling Fan and RGB ICE Tower Cooler with Heatsink for Raspberry Pi 4 Model B, 3B+, and 3 Model B by Eric Pavelko

With this miracle cooler I managed to achieve a super stable CPU overclocking to 2.3 GHz and GPU overclocking to 750 MHz on my Raspberry Pi 4 (8 GB model). The idle temperature is around 30-33°C and never rises above 50° for more than 15 minutes even after all cores are fully loaded (with stress ng), after which the temperature seems to stabilize. I could be wrong, but I believe the Pi firmware starts mild thermal throttling at 60°C and then kicks in full throttling above 80°C. With an ICE cooler, you won't get anywhere near these thresholds, even at the highest possible overclock settings you can control on the Pi 4. The bottleneck is the Pi 4 itself. Usually at this point, any attempt to increase the performance of the Pi 4 processor results in a stress ng test failure or boot failure. But! Temperatures never reached throttling levels, even on extreme settings with high peaks. I'm testing, the crash was caused by the processor's performance limitation and physical limitations. The RGB-lit fan is definitely an eye-catching touch that might not be for everyone, and definitely adds to the absurdity and charm of this little desktop class. Heatsink, but it comes with a non-RGB black fan that can be turned off. The kit also includes some paper-thick thermal pads, but I only used high-quality thermal grease when installing the heatsink. Yes, it's really overkill at this point, but hey, be big or go home, right? Definitely recommended for those Pi enthusiasts!
