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
