Review on Enhanced Cooling Fan and Heatsink Set for Raspberry Pi 4B, GPIO Expansion Board with LED for Raspberry Pi 4B/3B+/3B, DC5V 0.2A - MakerFocus by Jason Sullivan

Does what it's supposed to. Keep heatsinks in place to get the right type of heat dissipation for the IMO electronics. The price is unbelievable. So far I've had cooler temps while idling and only once did I barely notice it getting louder. Will try emulation soon to see if it gets any louder at all. The blue LED is a quiet and pleasant addition that allows you to see the device in low light and just generally looks cool. I haven't tried Pina but it worked. Only added risers with screws and this was done after slowly pushing them towards the pins. Definitely recommend! I've even put it in the official clear sleeve with only minimal sanding of some of the nicks. I liked it better outside anyway! Good product!
