Newegg offers the refurbished Cooler Master 95mm Rifle CPU Fan, model no. DP6-9EDSA-0L-GP, for $7. Redeem this $7 mail-in rebate to cut that to $0. With 99 cents for shipping, that's tied with our mention from two weeks ago and $10 under the lowest total price we could find for a new one. It's compatible with Intel LGA 1150/1155/1156. Deal ends November 30.
Note: A 90-day warranty applies, although it's unclear who backs it.
