“Reviews of the Raspberry Pi 4 all recommended cooling the CPU. Even for a sausage-fingered bodger like myself, fitting the Fan SHIM was entirely straightforward. It is practically silent. Everything worked out of the box. What more can be said?”
“When I barely notice though my hearing isn't the best, others with more sensitive hearing may disagree with me. My Pi 4B / 4Gb idles at ~57 C but activating the shim drops to ~37 C.
With a stress test the shim is activated @65 C and quickly drops the temp to 55 C.
Easy to install both software and hardware and prompt delivery from Pimoroni as expected.”
“The fan is very quiet, and effective in reducing temperatures down to managable levels. The Python software for automatically starting and stopping the fan when required is a nice touch. It's worth know that the RGB LEDs can be controlled independently of the fan operation. Thus you can just use the one board if you want to use them for an easy-to-read status indicator.”
