AAB Cooling NC80 is yet another AAB COOLING cooling pad, which has two efficient and quiet fans. Ideal for large laptops up to 17″. The silent laptop cooling pad provides a stable base for your laptop, while the rotary potentiometer enables simultaneous fan adjustment. Five fans take cool air below the stand and direct it to the laptop surface while providing low noise emissions. Hydraulic bearings work very quietly. When setting the lowest fan speeds, noise is practically inaudible (SUPER SILENT mode). The lower part of the base has a 5-step tilt adjustment to ensure the highest ergonomics. An additional advantage of the gaming laptop cooler is the small legs that increase the angle of inclination in the flat position, the anti-vibration pad and the blocker to prevent slipping of the laptopop fan technical data:Dimensions: 415x260x35~180mm (L x W x H)PS4 cooling pad material: Aluminum + Plastic – glossy frameWeight: 820gPlug & Play Version – just plug it to make it work, Data Transmission: USB 2.0 & 1.1 ports to 480MbpsPower supply: USB 3.0/2.0/1.1/1.0, 5V DCPower consumption: 0,4A~0,65A/ 2W~3,2WFans dimension: 125x125x20mmNumber of fans: 2, BLUE LEDFan speed (regulated): 0~1200 rpm ± 10% Airflow: 115CFMNoise: level of 11dB(A), SUPER SILENT modeTilt adjustment: Five ranges and additional legs providing more anglesSize of two front blocks (bookends): 42×16 mm (L x H)Power cord length: 60cmBearings: HydraulicLifespan: 50000h- Compatible with all notebooks / laptops of different matrix sizes.
