"HIS HD 4670 graphics beats GeForce 9600 GSO in high settings!" - Comparsion based on AMD internal testing


The Ultimate Silence Media Center PC!


HIS unveils the HD 4670 iSilence 4 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.

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 HD4670 iSilence 4 model and the HD4670 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

"  HIS 4670 iSilence 4 is an excelent graphic solution for the users who are looking for an afordable system; silenced and capable of playing latest games " - XtremPC Review

" The iSilence 4 cooler that HIS used on this GPU shows that it is more then capable of handling the heat out put of this card. Barely topping at 55°C and that was when the video card was overclocked.  "

" A quick glance around the internet, I seen this video card go from 100-120 USD, making the iSilence 4670 video card a perfect price for those on a tight budget but still wants to be able to play games with out sacraficing to much as far as visual quality. " - scores 8.0 out of 10 and receives the Bjorn3D Seal of Approval
