Zalman took its first dip into water cooling after a while, with the CNPS20LQ, a self-contained (closed loop) CPU cooler. Designed and made originally by Asetek, a well-established brand name in OEM water cooling solutions, the CNPS20LQ uses a single-fan (dual-fan capable) radiator design. Its radiator measures 120 (W) x 158 (L) x 25 (H) mm. The radiator houses a small reservoir. The block houses a pump, which draws power from standard 4-pin CPU power header, and supports PWM control. The two are connected by flexible tubing. The block features a copper base with pre-applied thermal interface material. The CNPS20LQ supports all current socket types, including Intel LGA2011, LGA1155/1156, LGA1366, LGA775; AMD AM3+, FM1, and AM3/AM2+/AM2. It is priced at €69.90.
