We are proud to present the new Rev. 2 Magicool "MC" CPU cooling block. The new block is essentially smaller than the old CPU block. A modified form of cooling fins was designed in this block and warranted top cooling performance around the clock. With an integrated pin grid array for optimum cooling this copper block is has a high surface area for heat dissipation. This is one block that will cool almost any processor on the market without buying extra mounting plates and is perfect for those always upgrading to new and different processors. New is an Acetal top!
