“Active cooler fits vwry well. Doesnt come with instructions and far more thermal paste than needed, but both easy enough to overcome. Very nice qnd quiet too.”
“Beautifully machined and simple to install. Can't really comment on how loud the fan is as I don't seem to make the Pi work hard enough to need it! It's a little noisy when it spins up during boot, but it's running full speed and only for a couple of seconds. Even without the fan, the heat sink keeps my Pi at about 45 degrees while I'm writing code and generally messing around so I'm very happy with it. For a fiver, you can't go wrong”
