MSI have released a R4890 Cyclone graphics card which has built-in 800 stream processors and 1GB GDDR5 256bit high speed memory. MSI R4890 Cyclone series is the only HD 4890 graphics card in the market equips 10 cm extra large PWM fan. By taking the advantage of the low rotation rate of the big fan and 8 mm SuperPipe, the operating environment is quite and cool. MSI R4890 Cyclone series adopted military class components, such as Hi-c CAP, SSC (Solid State Chock), and long-life solid capacitors, to not only stabilise the GPU power supply and extend the life span of key parts, but also reduce the high frequency noise. Through the magnificent improvement in cooling system and materials, MSI R4890 Cyclone has made a breakthrough of core speed 1GHz limitation.

Cyclone Thermal Design

The cooling system of MSI R4890 Cyclone series equips 10 cm PWM fan which is the biggest on HD 4890 in the industry. Because of the bigger fan, large amount of air flow takes away the heat with lower fan rotation rate. Cooling efficiency can be increased and operation noise can be reduced. Moreover, MSI R4890 Cyclone carries 4 heat pipes to quickly take away the heat. With an extra large 10 cm PWM fan, MSI R4890 Cyclone series provides the coolest operating environment for system to achieve the best performance.

SuperPipe TechnologyR4890 Cyclone

The heat pipes are one of the most important components in the graphics card they transfer the heat from the GPU to the fins of the cooler. The thicker the heat pipe, the faster the cooling speed. MSI unique SuperPipe technology uses 8mm heat pipe which is 60% thicker than traditional ones and increase 90% of cooling efficiency.

Military Class Components Hi-c CAP

In order to provide consumers longer life and better quality products, MSI R4890 Cyclone series uses high quality Hi-c CAP to supply better GPU electricity. Hi-c CAP is comprised by rear Tantalum which is an extremely expensive but steady metal. Under 65°C operating environment, Hi-c CAP can last over 200 years making it the best capacitor in the industry. Furthermore, Tantalum's high stability greatly reduces electricity less package and provides high quality power supply. Under the condition of overclocking and high temperature, MSI R4890 Cyclone series can still provide stable performance.

Military Class Components Solid CAP

The capacitor is one of the most important power supply components. Good capacitors plays a critical role in system stability. Liquid and solid capacitors are the two main capacitors in the market. Solid capacitor have a longer life span than Liquid. Under the high frequency and high temperature operating environment, solid capacitors provide an even more stable power supply. Moreover, solid capacitors contain no liquid, therefore leakage will not occur. To ensure best product quality, MSI R4890 Cyclone series adopts Solid CAP.
