Features: brand new and high quality The MINI volume TDP is upgraded to ≤80W by using high-efficiency heat pipe with unilateral power theoretical value of 40W and fine-tuning. Efficient heat dissipation, temperature control and speed regulation adopt 9015 PWM 4PIN temperature control fan. Four copper nickel-plated heat pipes combined with 40 large-area FINs fins of aluminum. 9cm size without fear of MOS tube interference. Adjust the new parameter value of the heat pipe, and the direct contact modes of the heat pipe reduces the thermal resistance and provides the antipyretic efficiency. Specifications: Material:Metal Type:For Intel/For AMD Fan interface: PWM4pin Air volume: 40CFM Fan speed: 800-3600RPM(PWM) Noise: 17-35.8dB(A) Input voltage: 12V Size:Approx.94x94x30mm/3.7x3.7x1.18inches Package Includes: 1x CPU Cooler note: 1.Please allow 1-2cm errors due to manual measurement, make sure that you do not mind before you order. 2.Due to the difference between different monitors, the picture may not reflect the actual color of the item.
