Thermalright HR-09 Type 4 MOSFET Cooler

As you may or may not already know, there are three major heat sources from your computer system, the CPU, the Northbridge and Southbridge chipset, and the MOSFET.
The increasing density of MOSFETs on an integrated circuit is creating problems of localized heat generation that can impair circuit operation. Circuits operate slower at high temperatures, and have reduced reliability and shorter lifetimes. MOSFETs are at risk of thermal runaway. As their on-state resistance rises with temperature, the power loss on the junction rises correspondingly, generating further heat resulting in destruction of the device.
Many motherboard manufacturers have installed their own heatsinks and cooling systems, but these are still inadequate when running increased voltages. Thermalright has done extensive research and developed a MOFSET cooler designed for high voltage overclocked systems, that both give better performance and longer system life

• IFX designed fins with proprietary thru holes.
• No-tool, easy and fast installation.
• 6mm heatpipes nickel plated to prevent oxidation maintaining best heat transfer condition.
• Copper heatsink base with each fin soldered to heatpipe for most efficient heat transfer.
