stock AMD cooler is as $hitty as you can go, get something like Zalman or Corsair, or go liquid.
that was one of main issues with my buddy's computer, still is.
right now I have Antec Three Hundred, but that was on sale at local best buy, with SSD mount, cant beat $45
personally I love Lian-Li, they made out of aluminum, which helps dissipate heat, and brushed metal looks good,
Next time I will try to get my hands on Cooler Master Stacker 830.
