Conclusion: My inner engineer loves this thing. Beyond the fact that it works really well, it looks good too. It's a classic case of a design where form follows function. It's round because the fan is (naturally...) round, it's made out of copper because copper conducts heat 70% better than aluminum. The incredibly smooth base is plated with copper instead of nickel because copper conducts heat 400% better than nickel.
Pros: Full Copper design looks great, works great at all speeds, Very quiet, inaudible in my application on High Speed, Includes adjustable fan controller, Simple, flexible, and sturdy mounting system, Impeccable surface finish on cooler base (copper plated), Well balanced design; no unnecessary features and no weak points
Cons: Application data out of date, no nVIDIA 8XXX or 9XXX cards listed, If used in poorly ventilated cases, will raise case temperature, Clear insulating washers almost invisible, easily lost once removed from package
Summary: The first chart below shows how the stock noisy-at-full-speed cooler performance as compared to the VF900-Cu LED at both low and high fan speeds. High fan speed on the Zalman cooler is much, much quieter than the stock cooler when running 3D applications.
Pros: Very good installation instructions., Dual heatpipe design., Fan Controller., Quiet at low-mid speeds., Blue LED fan.
Cons: Fan Mate 2 Controller could integrate better with the system., Two slot cooler.
Zalman VF900-Cu LED: New Universal VGA Cooler Review
4 August 2006
Summary: Cute appearance, high efficiency, a very quiet fan with highlighting, tool-less installation on the graphics card – these are the features the new VGA cooler from Zalman will bring to your system. Read more in our review of this solution!
Pros: High GPU cooling efficiency, Very quiet at medium and silent at minimum fan speed, Compatible with almost all existing graphics cards, Simple to install, Fan Mate 2, good thermal paste and memory heatsinks in the package
Cons: High price, Worse than the Zalman VF700-Cu at cooling the graphics card’s PCB and power circuit (this is true for the Radeon X1900 XTX)
Conclusion: The numbers really show that this is a great product, and I can admit that the noise is ALOT lower than on a stock cooler. That is what I expected but I also saw a huge performance difference and with a lower temperature on the card you get more stability and a bit more overclocking potential. Zalman has made it again with this new GPU cooler and I want to give it 5 out of 5 and our editors choice award. Why you say?
Conclusion: Zalman does it again. The VF900 has everything any enthusiast would want. It’s quiet, quality, easy to install and performs well. Its Computer Noise Prevention System (CNPS) works exceptionally well as always. The VF900 inherited all of Zalman’s positive qualities and technologies, and created no new negative ones. The silence, performance, ease of installation, and small size were all there. Just about anyone can install this cooler.
Summary: The VF900-Cu is an excellent VGA cooler produced in typical Zalman-quality fashion, but at the end of the day I can't help but feel somewhat let-down. The overall fit and finish on the 9 is good, although I was confused by the installation procedures due to a slight problem getting the thing to mount correctly. The copper base of the heatsink has a superb mirror-like shine to it and the rest of the cooler is equally attractive.
Excerpt: Sony Mobile started a new chapter of their smartphone design with Xperia Z. The refreshment was very welcome and Sony sold a large amount of smartphones since then, and Xperia Z, as a pioneer in this ... ASUS started with restyling the DirectCU model, which brought a breadth of fresh air in their recognizable design. With the cheaper GTX 760 model, aside from esthetics, there weren’t many changes.
