You've cooled your case, processor, memory, video card and hard drives. What's left? Oh yeah, the Northbridge. The SilenX IXN-40C will fit on most NorthBridge chipsets with mounting holes or spring mounts. The circular collection of copper fins provides plenty of surface area for great thermal transfer. The 3000rpm fan drives 6CFM of air over the fins, making it an even more efficient cooler. Keep your system the coolest, no matter how hot the action! Compatibility: Most Northbridge chipsets with mounting holes or spring mounts RPM: 3000 RPM Air Flow: 6 CFM Noise Level: 14 dBA Power Connector: 3 Pin Fan Color: Transparent Heatsink Dimensions: 54 x 54 x 27mm
