The ZM-OP1 80 mm fan was designed to enhance the performance of Zalman's ZM80C-HP heatpipe cooler. The noiseless ZM-OP1 comes with a fan grille and is slim enough that you can attach it directly to the cooler's heatsink without using a supporting bracket. In silent mode, the fan spins at 1,400 rpm (+/- 10 percent) with a noise rating of 20 dB. In normal mode, it spins at 2,800 rpm (+/- 10 percent) with a noise rating of 33 dB. The fan uses a ZM-MC1 (3-pin) multi-connector and a 2-ball bearing. It measures 80 x 15 x 80 mm (W x H x D) and weighs 75 grams. Its in-use life expectancy is 50,000 hours. You must use the ZM-OP1 with the ZM80C-HP if you're using an nVIDIA GeForce FX5800, an ATI Radeon 9800 Pro, a Matrox Parhelia, or a more advanced card. |
