![]() ![]() A quiet click can be heard a few inches away. The PWM functions of the SWiF2 120P were tested, using a grounded PWM wire for 0% PWM duty, and a Zalman PWM Mate to approximate 25%, 50%, 75% and 100% PWM duty. The PWM Y-cable included with the 120P has the RPM reporting line going only to one arm of the Y - that is a good thing: it prevents the motherboard from receiving more than one input and getting confused about the RPM. ![]() The cable ‘sleeving’ is black rubber tubing. The ‘Anti-vibration Bolts & Screws‘ are only about 25mm (one inch) long, so they are too short to pull through you must have access to the corners of the fan to use them. Now you will know how well the SWiF2 1200 cools in addition to the 1201 and the 120P. So the SWiF2 120P was tested at 0% PWM duty to provide a proxy for the SWiF2 1200. At 100% the fan ran 2083 RPM with a tone, so if clicking was present it would not be heard.Ī quick inspection of the factory specs shows that the bottom range of the PWM fan corresponds to the same specs as the 800 rpm SWiF2 1200. At 25%, 840 RPM with very quiet clicking at 50% 1293 RPM with fast quiet clicking at 75% duty 1804 RPM with quiet clicking. To hear a faint click you must put your ear right up to the fan.Īt 0 PWM duty, the Blade Master ran at 791 RPM with no clicking. The PWM functions of the Blade Master were tested, using a grounded PWM wire for 0% PWM duty, and a Zalman PWM Mate to approximate 25%, 50%, 75% and 100% PWM duty. Is it enough to cause some vibration? The fan does come with vibration pads, but does not seem excessively noisy even without them. The name ‘Cooler Master’ is stamped on one of the blades. Model number is advertised as R4-BMBS-20PK-R0, but on the fan there are two sets of numbers - A12025-20CB-4BP-C1 and FA7C1212ME-5BPNA - that bear no relation to Cooler Master’s model number. ![]() The fan comes with four 2mm thick triangular stick-on pads to reduce vibration. ![]()
