Thermaltake NiC C4 Review @ OCC
 

"Affordability is usually not the main focus for a cooling connoisseur, yet Thermaltake NIC C4 is the perfect CPU cooler for your buck. For the price of $54.99, the NiC C4 guarantees a thermal dissipation of 220 watts. In comparison to the NiC C4's older brother the Thermaltake NIC C5 priced at $59.99, which only dissipates 10 additional watts. The NiC C4 is more cost-effective for the budget conscious consumer. Besides the NiC C4 and C5, other coolers such as the Noctua NH D-14, Corsair H100i, and Corsair H80i are equivalent to the NiC C4, but they come with a higher price tag for that similar performance profile. If you need a reasonably priced cooler that can step up to the plate without striking out, then the C4 is one of the most valuable (and economical) players in today's CPU cooling market."
