Installation is a breeze on AM5. Hand tighten the hardware on with the brackets curving in just like the peerless assassin. Remove the center fan, and again like the PA use a long screwdriver to tighten down both sides of the cooler. Replace fan.
Cons: The readout requires a USB 2.0 port which my board only has one of. It is on the bottom of the board as far from the cooler as possible. I also only have one header so I'd have to get an internal extension hub, as my front panel is connected to the only header. The app required for the readout is another con. The last con is the fans have a high pitched annoying whine if allowed to spin fast enough. And that is why I don't recommend this cooler, even at the price. You would need to replace the fans, killing the value.
Pros: Looks great, cools well, easy to install.
