Processor cooler test - Noctua against Intel Core i5
The smallest of the three victims to be tested is examined first. This will only be good this way because the big ones don’t obscure the little salt with their glitter.
The rib has a vertical arrangement, i.e. it is perpendicular to the base plate, and the fan blows the cooling air in line with the plate. The material of the rib is copper and aluminum as we have become accustomed to. In our case, as is the case with other ribs, the base is made of nickel-plated copper, the heat-conducting tubes are also made of nickel-plated copper, and the lamellae are made of aluminum.
The pipes are 6 millimeters, so this is no different from the average. There are four tubes in the rib that leave the foot in two directions, so the heat leaves the processor in eight directions toward the slats. The slats have 36, their shape is normal apart from the front and rear profiles. They are wavy at the front and back, which we suspect is due to the reduction in airborne noise. The sides of the slats are partially closed, so the flowing air gets a definite direction, you can't just squeak back and forth.
The rib also comes with a fan (Noctua NF-B9-1600), a 92mm piece. If that weren’t enough for someone, you can attach another one to the other side of the slats, so even two air choppers can cool the ribs. The shaft of the factory-supplied fan makes 1600 revolutions per minute, moving 64,3 cubic meters of air per hour, while loading our ears with 17,6 dBA.
As we have become accustomed to with Noctua products, there is a technology called ULNA, which is nothing more than two fan connectors connected to a lead and a ballast resistor. Its role is simple, thanks to the installation of the resistor, the fan receives less voltage, so it rotates more slowly and of course is quieter. ULNA stands for Ultra-Low-Noise-Adapter. Is he brilliant?
Incidentally, the rib measures 125 × 96 × 95 millimeters and weighs 460 grams. With the clamp in the factory box, it can be used for processors that fit into LGA775, AM2 and AM2 + sockets, but as our article shows, the clamp LGA1156 is also available. In addition to the fan and clamp for the rib, we also get the thermally conductive grease sold under the name Noctua NT-H1.
