Zalman CNPS10X Performa CPU Cooler

The Zalman CNPS10X Performa CPU Cooler




As I mentioned previously, the Performa is a squat build. Looking into the 47 fins, they seem placed closer than usually seen in a cooler. All that aluminium with the five copper heatpipes supplying them makes for an efficient design.




From the side you can now see all five pipes instead of the two rows from the front. Zalman also offers dual fan mounting with the Performa utilizing the grooves in the outer edges.




At first glance the Performa looks like a typical tower cooler, but from this angle you can see a bit of originality in the shape of the fins. The embossed lines around the edge add a bit of style as well as a bit of structural support for all those fins.




Seems direct touch used to be the king of cooling tech, but Zalman brings us a cooler with an all copper base below the pipes. This proves in my mind that direct touch is an OK concept, but you don't need it to break out from the pack. A well designed cooler with a flat base and good contact to the heatpipes is just as capable.




While it doesn't have a polished base, the last image was rather flat. This is just to give a better idea of the finish that comes on the Performa out of the box. Not too far off from what I would do lapping it up to say a 1500 grit sandpaper judging by the reflectivity.




From the front you can see there is only one set of mounting holes at the bottom side. This allows for a more unencumbered entry of air flow to the fan blades. While there is the RC24P connected to the fans 4-pin connection, if you want to unleash the beast within, I don't suggest you use this resistor.




For those who like to see what the fan draws during operation, you can see this fan hits 2000RPM using only 0.20A to get it done. Using the fans model number only brings me to other mentions of the cooler itself and not to any real specs on the fan.




In preparation of the fan placement, you need to dig into the hardware goods to find the anti-vibration strips to lay them onto the cooler to keep the fan isolated from the cooler. Also notice the wavy bit in the middle. This should create a bit more disturbance of air flow in the middle where the fan is less likely to have great CFM. The disturbance should help speed up the airflow, and almost create a low pressure area behind the hub of the fan to increase overall heat dissipation.




The choice of fan is superb, the fan is larger than the fin assembly and that means two things. Better coverage of the surface area of the cooler, and that this fan can offer airflow to the motherboard as well, if positioned low enough.




From the side you can see again how well it covers the fins. Also, it's very easy to see how two fans can be mounted to the Performa for even better performance, if you really need that.




Something typical with the Zalman fan, not only is the front mounting corners removed, but there is a good amount of the sides removed which actually allow for a bit of the blade to be exposed. This should do two things; allow for a bit more air to easily enter the fan and seemingly it should help with noise as well.
