MHW looks at the new mostly aluminum XP-120 HSF which is slotted for a nice big 120mm fan.

"As mentioned earlier the XP-120 offers cross platform compatibility, but because of its enormous size that compatibility is somewhat limited. My personal suggestion here would be to make sure your motherboard is on either the AMD or Intel approved list before you buy one. If you don't see your board on the list it can't hurt to drop Thermalright a line and ask."
