Review on 🌀 Efficient Cooling Solution: Argon Fan HAT for Raspberry Pi 4 Model B and Raspberry Pi 3 Model B – 40mm Fan with Power Button & Software Control by Elijah Pope

. Not only that, but if you try to just push it in with the pins, you'll find that the screws holding the fan itself to the board are secured by a nut that contacts the stock PI CPU heatsink comes. . (I hope I didn't damage the PI motherboard itself when trying to remove the hat, which inevitably pushes too hard in this scenario.) Simply adding something to mount the device would make all the difference if this one device is a waste of time. Time and the resulting instant payoff for most people. (Again, if properly assembled, the pins won't be long enough to make contact with the terminals on the hat, right? It actually looks like poor design to those who don't do the whole "mad scientist" with it.) If When I buy a pair of shoes, I expect them to be laced. I am returning this on principle.
