As a thermal management method of FPGA, heat radiation method by N-9H is receiving a lot of attention from a engineers in Japan
《Uniqueness of N-9H》 Making miniaturization of all kind of heat sink.
Noise will not occur from the N-9H heat sink. As a noise countermeasure heat sink. As a EMC heatsink.
Cooling Fan, Sheet, grease, or thermal pad is not required. Simple screw cramp is recommended.
《Performance comparison between usual heatsink VS N-9H》
Using Heater as a heat generator（25×1.75t、100V-100W）control the temperature on its surface 150、180、250℃
Compare the temperature on heater’s surface after 30 minutes operation. Condition is closed space with no wind. Temperature of testing room is usual room temperature.
