Seismic Audio SARF1, Dual Cooling Fan for Rack Case

I bought them to cool my new receiver/amp that has to generate enough power to drive 2 KEF Reference Series floor speakers, 2 Klipsch Heresy speakers, 2 ADS front speakers and 2 Onkyo rear speakers. That generates a great deal of heat and these two SARF1 fans cool the Pioneer Elite very nicely. An interesting alteration that I made was to have the power cord moved so it came out the side rather than next to the on/off switch as the distance between the top of the amp and the shelf above it was 1/2 " too small for the fans to fit. Now I have these superbly built fans delivering good airflow at a volume that is completely drowned out even when listening at low volume. If you need fans to cool your gear buy these.
