This newly updated version (rev. 2) of the XiR-2300 features a bracket for the Intel i7 CPU.

The Nexus XiR coolers combine some of the most advanced technologies in the market used for CPU coolers. Heat pipes, SkiveTek and ultra-thin fins combined with a real silent temperature controlled fan delivers ultimate performance which has never been this quiet before.

XiR coolers are crafted out of the purest aluminum and copper materials. The heat sink covering the heat pipes and the copper base is made using SkiveTek technology. We have managed to apply the best technologies at the best position on the cooler. And the result is astonishing...

The temperature sensor on the fan makes sure the fan speed is always at an optimal lowest speed. The speed can vary between 1500 and 2500 RPM creating a noise-output of an inaudible 15 dB(A) up till a still truly quiet 24 dB(A).

You should really experience it yourselves; high-end performance and low-noise combined. The XiR cooler range is your best choice!

ohh...before we forget. We put two orange LED in the fans center core...just for fun.

Fan specifications

Both the Xir-2300 and the XiR-3500 use the same fan so fan specifications are identical. Performance difference between the XiR-2300 and XiR-3500 is caused by the different materials used for the fins. The material of the fins does not influence the noise level of the cooler.
