Zalman presented the CNPS9900A LED, a new all-copper processor cooler that it very similar to the CNPS9900 LED. The main difference between both coolers is that the new model features a Zalman RC33P resistor cable and a tube of Zalman ZM-STG2 thermal compound. The cooler supports all the latest sockets from Intel and AMD, it is expected to be available for around $64.
he construction involves a copper CPU contact base from which three heatpipes dissipate heat two two circular copper fin rings on either sides of a blue LED-lit 120 mm fan. Without the RC33P cable, the fan spins at 1000 rpm ~ 2000 rpm, with noise levels of 19.5 dBA ~ 38.0 dBA. But when the RC33P is installed, the speeds and noise outputs are reduced, at 800 rpm ~ 1300 rpm, with noise levels between 18 dBA ~ 28.5 dBA. The ZM-STG2 thermal compound has a thermal conductivity of 4.1 W/mK. 3.5 g of this compound is supplied in a tube.
