Often, people will say the only way to eliminate a PC from making noise is to remove all of its fans, that water cooling, hard drive enclosures, and foam-sealed cases are the way to go. But under normal circumstances, no computer is ever totally silent. Rather, your ears determine the degree of noise being emitted and what may seem like a silent PC is simply a quiet PC. With cooling manufacturers constantly searching for the greatest performance/noise ratio, there are already a variety of cooling solutions for users looking to build a PC easier on the ears. QuietPC.com specializes in quiet cooling products like HS/Fs, case fans, and power supplies from companies like Zalman, Acousti, and Fortron. Today Dev Hardware will look at the Arctic-Cooling Super Silent 4Pro L CPU cooler, provided by QuietPC.com.
Arctic-Cooling, "the experts in noise reduction," is based in both Switzerland and Hong Kong. As the motto suggests, they specialize in quiet cooling products including CPU coolers (Intel/AMD), VGA coolers, and fans. The availability of their products here in the US however, is limited; there are just eight online vendors selling their stuff.
The heat sink and fan being reviewed today, designed by Arctic-Cooling Switzerland, is the Super Silent 4Pro L priced at $21.95 (from QuietPC.com). This is their latest model for P4 socket 478 CPUs up to 3.2GHz, and is made entirely out of aluminum. It features an optimized 80mm blue lead fan based on four rubber bumpers which nullify vibration, three selectable fan speeds, and easy installation compatible with the regular P4 retention bracket.
The 4Pro L comes neatly packed in a small plastic box with a little tab at the top. The following picture of the side of the box shows the specifications of the cooler.
As shown, the three selectable fan speeds, low/medium/high, are 2000/2500/3000 RPM respectively. With the high fan speed only rated at 25 dB, the 4Pro L is clearly a quiet cooler, assuming that rating is true. It is able to cool Intel's latest CPUs, given the 80mm fan can still push at least 25 CFM at its lowest speed. I am not quite sure how Arctic-Cooling determined the "up to x.x GHz" for each fan speed however, because I was able to use it with my overclocked processor past 3GHz without a hitch.
