“When I bought my Raspberry Pi Compute Module 5 development kit I was surprised that a heat sink for the compute module was supplied as well as a cooling fan BUT both could not be installed at the same time as each other due to height restrictions. Along came the teaser advert for this Cooling fan and I got myself on the email list for availablility. The Pi Hut were good in their promise and let me know when it was available. As soon as I saw that it was I ordered one. It came prompty and included the fan/heatsink, four thermal pads, two sets of spacers, two sets of fixing screws and even a mini screwdriver. However, there was no instruction as to assembly. A quickly responded email to support pointed me in the direction of https://www.waveshare.com/cm5-fan-3007-b-5v.htm where a detailed guide can be seen.
The fan/heatsink is now installed and operational and I am very happy with the product and service provided by the PiHut.”
