Excellent Cooling Performance The ultra-quiet 80mm PWM fan & an optimized heatsink give the Alpine 11 GT the best price / performance ratio. Virtually Silent The combination of a low noise impeller & the patented fan holder makes the Alpine 11 GT virtually silent even at full fan speed. Thanks to the PWM control, the speed of both fans adjusts according to the temperature of the GPU & thus the noise level remains at an absolute minimum which qualifies it as a silent cooler. Click here to see how the PWM control settings can be changed according to your performance & noise preference. Compact Design This compact cooler with a quiet 80 mm PWM fan can deal with a TDP of 70 Watts & thus cool most CPUs. Due to its capability to draw air from the side & its low profile, the Alpine 11 GT is a perfect choice for small form factor PCs. Easy Installation The approved mounting system via push pins offers excellent stability & is applicable within seconds. The pre-applied ARCTIC MX-2 high performance thermal compound makes the installation a quick & clean process.
