Pros: Came packaged just as if it was brand new.Very good cooling performance,keeps my 5820k at about 25c idol and max 50c
at full load with a modest 4.5ghz overclock.

Cons: The fans can get pretty loud,but i game with a headset so it doesn't bother me to much.

Other Thoughts: all in all i'd recommend it.at 70 bucks you definitely can't beat the price.
and it works very well.

Pros: -It works very well, even on an older architecture based X4 860k. It did a good job of keeping the CPU under 60c always, even when stressed to the absolute maximum. Before this, the stock cooler kept it at a nice and chilly 98c when under a comparable load which would cause thermal throttling.
-Terrific value. Thick 240 rad where as the competition within the price-point is mostly dinky 120's.
-Refurbs don't bother me- the weak point has already been located and fixed by hand by the manufacturer.
-At least on my board, I was able to completely hide the pump-plug by wrapping it around the base of the cooler, leaving almost no indication of wiring at all- ignored the included fans and simply used my case fans instead, leaving practically 0 cable management to deal with.

Cons: The pump/block had a large scratch where the Corsiar logo lights up. It was easily fixed with some black perminant marker and a little bit of time. But, seeing as the internals of my case are practically pitch black with a red LED accent, the mark doesn't show up at all unless closely inspected.

Other Thoughts: The pump will move around a lot of bubbles when you first turn your PC on with the new cooler attached for the first time- that's okay, it's just pushing air to the top of the reservoir inside of the radiator- let it finish the process and carry on.

Pros: overclocking a 1100t phenom 6 core at 4.2ghz, my cpu temp at max usage is about 35c. Im sure i could overclock even more with no temp problems. Very satisfied i have been able to open the bottleneck on my pc.

Cons: none

Other Thoughts: Cant argue with the price unless it breaks on me, but i hope not.

Pros: Keeps my i5-4690k @4.2GHz between 30°c and 50°c, which helps keep overall temps down.

Cons: at full speed, these are the loudest fans I've ever had the misfortune of owning. incoming fan controller, +$30 :/

Other Thoughts: was only $70 refurbished, can't complain. I'd recommend it in a heartbeat for $70 :)

Pros: Mine was actually brand new? It keeps my i5-4690k at a cool 27C

Cons: The radiator might hit your MoBo
