They're both good coolers.
I replaced a 212+ with an A70 in one of my rigs.
The A70 with the line resistors and two fans is quieter then a 212+ with one stock fan.
CM coolers are easier to install though.
Pricematch the EVO = Hehe!http://www.directcanada.com/products/?sku=11130AC0554&vpn=RR-212E-20PK-R1&manufacture=COOLERMASTER
You can't make a bad choice with either cooler.
Both come with good paste.
Advantage CM = comes with a tube for @4 installs.
Corsair = packet for one time install.
