Easy as hell to clean, the bracket holding the fan pops off when you need to.
Cheap as hell,
Not loud, even when going full whack
Cools pretty well.
It's a bit bulky and on some MOBOs the fan can protrude over the ram sockets, which forces you to use ram with no or low profile heat sinks.
It can be a bit of a pain to install because of the fins on the radiator, they're kinda sharp enough, I wouldn't hold it sideways anyway.
It's certainly not a "Blow Dryer" and it's great value for money imo.
