Cooling is handled by a 120MM ADDA fan. But the impressive cooling characteristics of this power supply have more to do with the fan controller than it did the fan. I have to say that I never worked with a power supply that adjusted the fan RPM so precisely, to such subtle changes. When temperatures increased, the fan was quick to spin up, but when things cooled back down, the fan spun back down to a lower RPM. The fan never spun any faster than it needed too. I've gotten used to fan controllers that waited "too long" to spin the fan up, and then spun the fan up to full RPM leaving me with "all or nothing" fan noise.
Essa revisão é de 2006 e eu acho que eles pararam de fazer esse modelo, mas existe um novo modelo HX650 .
