Many end-users also have written to us in regards to the above issue. They got tired of gimmicks and low grade thermal solutions. What they needed was something real, something that actually cools the MOSFET, and so we went to work and developed a new product called HR-09 (from High-Riser series) MOSFET cooler.
The HR-09 MOSFET cooler with its patented design will expand your system life expectancy and creates a stable condition not only during normal operation but also when you increase the frequency and voltage to overclock. Now heat is no more an issue.
HR-09 has two types. How do I choose which one to install on my motherboard?
If your motherboard is by ASUS and its single MOSFET is near the I/O port, HR-09U would be the ideal version to install since HR-09S would more than likely get interfered by the surrounding components. But if your motherboard is of Gigabyte, You can purchase two HR-09S, or one HR-09S and one HR-09U depending on the size of your CPU heatsink. More FAQ..
