Welcome to the store! Features: MINI volume TDP is upgraded to 80W by using a high-efficiency heat pipe with a unilateral power theoretical value of 40W and fine-tuning. Efficient heat dissipation, temperature control, and speed regulation use a 9015 PWM 4PIN temperature control fan. Four copper nickel-plated heat pipes combined with 40 large FINs aluminum fins. 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 reduce thermal resistance and provide antipyretic efficiency. Specifications: Material: Metal Type: For Intel/For AMD Fan Interface: PWM4pin Air Volume: 40CFM Fan Speed: 800-3600RPM(PWM) Noise Level: 17-35.8dB(A) Input Voltage: 12V Size: Approx. 94x94x30mm/3.7x3.7x1.18inch Note: 1.Please allow 1-2cm error due to manual measurement, make sure you don't mind before ordering. 2.Due to the difference between different monitors, the picture may not reflect the actual color of the item.
