HIS H465PS512P HD 4650 Video Card

HIS HD 4650 iSilence 4 512MB (128bit) 800MHz DDR2 PCIe

The Ultimate Silence Media Center PC!
HIS today unveils the HD 4650 iSilence 4 1GB/512MB DDR2 PCIe Card, deliver the ultimate silence solution for media center PC. Featuring the famous Korean cooling expertise's product – ZALMAN VNF100, it maximizes cooling efficiency while provide a silence environment for gaming and multi-media entertainment.

It is powered by the 4600 GPU with core speed up to 600MHz and memory speed up to 1000MHz. It has the same engine architecture as the HD 4800 Series and can propel you deep into your game play with fast frame rates and high resolutions. The Unified Video Decoder 2 technology enables you to get the ultimate visual experience for the most processing- intensive content. Take full advantage of Blu-ray functionality with dual-stream, picture in picture capabilities.

Cross over with Zalman latest innovative heatpipe solution
It is cooled by the well-known Korean cooling expertise's product – ZALMAN VNF100. With Zalman's patented VFP (Variable Fin Profile) Fin Design, it maximizes cooling efficiency and dissipation surface area for excellent performance. As VNF100 is fanless, it does not emit any noise and can be used semi-permanently. Coming with 3 high performance heatpipes, it maximizes heat transfer. The thin aluminium fins (0.4mm) provide minimized heatsink weight, and prevents excessive force on the VGA card. More importantly, the heatsink is positioned above the VGA card that optimizes cooling efficiency and allows compatibility with CrossFire setups.

Performance Test
Test is setup to compare the temperature difference between the HD4650 iSilence 4 model and the HD4650 standard cooler. From the following graph, the HIS iSilecnce 4 cools down the GPU temperature by up to 10%. Passively cooled by the passive cooler Zalman VNF100, the newly designed heatpipes convey heat to a large and dense array of aluminium fins, effectively cool down the temperature and ensure the station runs in stable condition.

What Expert Says
"With the location of these fins being above the PCB in most installations, better cooling is achieved with air heated by the card moving upwards." – TechPowerUp.com
