Newegg offers the Cooler Master Hyper 212 EVO CPU Cooler, model no. RR-212E-20PK-R2, for $34.99. This $5 mail-in rebate cuts that to $29.99. With free shipping, that's the lowest total price we could find by $5, although we saw it for $9 less last summer. It fits Intel LGA 1366 / 1155 and AMD FM1 / AM3+ processors. Rebate expires April 6.
