The Best 8 Inch Computer Cooling Fan

EC Fan What is EC technology?
EC stands for Electronically Commutated, and it combines AC and DC voltages bringing the best of both worlds; the motor runs on a DC voltage, but with a normal AC supply.
EC motors have several benefits. Because EC motors have no brushes, they do not spark or have a short life due to brushes. Other advantages include the fact that they do not waste power because the electronics control the stator; they provide better performance and controllability, and they run cooler than induction motors; In terms of size, small motors can achieve the same output as traditional DC or AC motors.
Power distribution is much cleaner with an EC motor. Brushless DC motors depend on a separate DC power supply. And an AC motor’s power supply usually adds extra cost and complexity. EC motors can connect directly to AC main power supply with their integrated electronics. They do not completely depend on voltage or frequency; hence, small changes in voltage do not affect motor output.

The EC fan is more windy than the AC fan, more energy efficient, and can work in the 70V – 270V voltage range, such as work under on 110V, 120V, 220V, 240V ,the fan speed are the same.

Product Description

High Air Flow for maximum cooling performance, quiet operation with low RPM, RoHS compliance for protecting the environment, Compatible with cosmos II, ATCs 840, haf 932, haf 922 and storm Sniper (no LED on/off function support), adds extra cooling for graphics cards when installed on side panels.

From the Manufacturer

Introduction

With the constant development of hardware getting better and better, the energy consumption of your computer rises because you want to get the full performance. Due to this the heat increases and so the requirements of your fan rise as well. To integrate several fans is not the right solution because your computer will get very, very noisy. Bigger fans are the optimal solution for modern high-tech systems. The MegaFlow fan has a diameter of 200mm and so it has a displacement volume of 184 m3/h – twice the volume of 140mm fans.

Application

• Cosmos S
• HAF 932
• HAF 922
• ATCS 840
• CM Storm Sniper

Recommended as a replacement or additional fan for:
HAF 932, HAF 922*, COSMOS S, ATCS 840, CM Storm Sniper*
*Fan and LED will operate but full LED ON/OFF function will not be compatible

Adds extra cooling for graphics cards when installed on side panels.

Overview

A quiet cooling fan system designed to be placed on top of AV components such as receivers, amplifiers, and DVRs. Maintaining an optimal temperature for components prevents overheating, ensures constant performance, and extends their lifespan. The LCD digital controller on the front of the system features a smart thermostat with speed control and status alerts. The steel enclosure houses three dual-ball bearing fans that pulls heat out of the component and exhausts upwards. Its slim low-profile design enables the unit to fit in tight spaces. On the backside are ports to connect and control additional fans. Includes corded power adapter to plug the fan system through an outlet.

Intelligent Programming

Programming includes an easy-to-use thermostat and a SMART mode that automatically adjusts the fan’s speed to react to varying temperatures. Additional features include alarm alerts, fan failure triggers, power savings setting, display lock, and backup memory. Six fan speeds are available with three screen brightness settings. Behind the unit are ports that can control up to six individual AC Infinity AIRPLATE Cabinet fans and MULTIFAN Component fans.

Design and Construction

Each system features dual-ball bearing fans rated at 67,000 hours and are certified by CE and RoHS. Fans contain a PWM-controlled motor used to minimize noise during speed variations and are suspended in mid-air with silicone mounts to absorb vibrations. A low-profile design allows the unit to fit in applications with a limited height clearance. Aluminum and steel construction enables additional components up to 30 pounds to be stacked on top.
