1. Pure copper heatsink base and fins maximize cooling performance. 2. Use of two high performance heatpipes maximizes heat transfer. 3. Circular heatsink formed by radially aligned ultra-thin(0.2mm) fins minimizes airflow resistance and maximizes heat dissipation surface area for excellent cooling performance. 4. Fan installed in the heatsink cools not only the VGA chipset and VGA RAM, but all other VGA components. 5. Does not exert any excessive force on the VGA card due to the product's light weight. 6. Improvement in the installation structure provides excellent compatibility and easy installation. 7. Adjustable fan speed controller(FAN MATE 2) enables control of noise and fan speed. 8. Does not generate noise or vibration in Silent Mode.&

I picked up the Zalman VF900-Cu Led cooler a couple of weeks ago to replace the stock cooler on my XFX 9800 GT. The noise of the standard cooler on the 9800 GT was just tolerable at low speed but when any demand was put on the GPU i.e. when gaming, the fan would wind up into an intolerable frenzy, which ruined what is an excellent graphics card. The VF900-Cu was in many respects an impulse purchase as I was desperate to rid the computer of the stock wailing banshee.
On opening the box I was pleased to see that the VF900-Cu was fairly compact, this was an important factor as I had a PCI sound card next to the 9800 GT so space was at a premium. The cooler is a beautiful piece of engineering the GPU contact surface was mirror smooth, the overall quality of the cooler is excellent. The contents were well presented and packaged, Included in the kit are 8 VGA RAM Heatsinks, a Fan Mate 2 speed controller, thermal paste and other various pieces of ironmongery to mount the cooler to your particular GPU.
The stock cooler was easily removed by unscrewing four screws on the back of the card (I was tempted to remove it with a sledge hammer but I managed to restrain myself). With a quick cursory glance over the excellent fitting instructions provided with the VF900-Cu I embarked on installing the new cooler.
It is important to remove all traces of the old thermal compound from the memory chips and the GPU before attempting to fit the self adhesive heatsinks and cooler. By this I don't mean wipe them over with an old sock you need to use acetone or alcohol to remove the all greasy compound. As I had neither at hand (and I sure wasn't going to waste my best 12 year old malt on it) I had to resort to using lighter fluid which worked remarkably well with no ill effects.
The fitting of the cooler was simplicity itself; just follow the instructions making sure you use thermal paste on the GPU as per instructions, when all is done plug the card back into the computer.
Well is it any good? In a single word remarkable. Let me explain, The XFX 9800 GT stock cooler used to sit at 61°C at idle and under load this would rise to 70 to 80 plus°C. At those temperatures I was tempted to plumb it into the central heating system! Note this card was not overclocked. Now with the Zalman VF900-Cu the temperature was astonishing 43°C at Idle and about 50 - 55°C under load. I have now overclocked this card to the limit and under heavy load it still stays below 70°C. The fan can be adjusted with the supplied speed controller and at max chat you can hear it but is far quieter than the stock fan. However, you don't need to run the fan flat out, you can adjust it to find the "sweet" spot finding the balance between cooling and silence.
In conclusion, this is an excellent piece of kit for the price. The temperature results say it all really; I was surprised at how well it performed under heavy overclocking conditions considering its fairly diminutive size in comparison to some other coolers. This cooler is the sort of thing that graphics card manufactures should be fitting as standard.Read more ›
I Brought this Zalman vf900 for my Inno3d 9400gt video card about a week ago and i must say im ever so pleased with it`s performance, The instructions that accompany the item are very simple to follow , Just make sure you clean the memory ram`s and the gpu processor with Isopropanol 99.9% before you attach this cooler and most Importantly make sure that non of the Capacitors touch the fan otherwise you can`t use it, The temps on the stock fan wasn`t that hight to start with but they were 37c low to 39c high vf900 temps are 30c low to 32c high. The Fan speed controler is easy to install you have the option of either sticking it to the case or screwing it in case you don`t want to ruin the paint job :-) it only took me about 15 mins to attach this cooler and it looks very nice and is very quite even on maxium spin.
My only one gripe is that it dosen`t have a light on the fan but i`m not going to send it back just for that :-) If your wondering about the noise level i have 7 120mm fans in my case and i can bearly hear them all, but i do have to wear sock loloolollo
I totally agree with a previous reviewer why dont the manufactors put theses fans on the video cards.
if your looking for a video card cooler you can`t go wrong with this one sure it`s a little pricey but you won`t be sorry :-)

5.0 out of 5 starsIncredible Cooler23 April 2009
By Fiorenzo Cattaneo - Published on Amazon.com
This cooler is fantastic. The build quality is very very good, and it dropped the temperature of my ATI Radeon 4850 video card from 70C down to 36C. It's also whisper quiet.
I'm definitely building this brand again.
Installation was very easy. One word of warning: you should buy the heat sink paste cleaner kit and clean the old paste really well, on both the graphic chip as well as the memory chips (the latter will be cooled by the small aluminum heat sinks which come with this product). I bought the Arctic cleaning solutions for that. Quite often people also buy the Arctic Silver heat-conducting paste. I just used the zinc paste which came with the product and I didn't have any troubles with it.

5.0 out of 5 starsSimply Amazing2 May 2007
By R. Smith - Published on Amazon.com
This GPU cooler is amazing. Dropped my temps by ~10c instantly. This cooler has turned me into a Zalman fan. The cooler is quite and kicks the crap out of the stock cooler. Definitely worth the money. I have the xfx 7900GS XXX
600M and it cools it to ~38-39c with ambient temp of 24c(room temp in home)
once I turn my AC on, no telling how low it will drop.

5.0 out of 5 starsVery nice cooler for the money1 April 2007
By C. Smith - Published on Amazon.com
I purchases this because I wanted something quiet, effective and not too large. This definitely accomplishes all those for my 7950GT even with the fan speed turned up to just about 1/3. It may struggle with some of the hotter cards but it cools mine very effectively.
Installation is a snap, although I did remove the adhesive thermal tape on the ramsinks and used Arctic Silver thermal epoxy instead. It does not appear to report fan speeds very well to my motherboard but this isn't a very big concern and could just be a defect with mine.

5.0 out of 5 starsFIts NVidia 9500 perfect, easy install5 Feb 2009
By Jason Short - Published on Amazon.com
Was worried that the 9x series chip from NVidia might not fit this, but it fit my NVidia 9500 GS video card easily. The built in fan was really loud and kept making awful noises. It came with an HP Pavilion Elite PC. I have two of these machines and both of the video card fans were really loud. After installing the cooler they now actually run almost 10C cooler, and even under full load are almost silent compared the the beasts that were on the cards before.
Instructions are pretty simple. Look at the diagrams and take them one step at a time. Thermal paste was included in the box, so that is another plus to me.

5.0 out of 5 starsCompact Design, Very Effective Cooling19 Nov 2009
By Jeff Chambers - Published on Amazon.com
I used this cooler to replace a stock fan on an ASUS EN9800GT/HTDP/512MD3 GeForce 9800 GT 512MB 256-bit GDDR3 PCI Express 2.0 x16 HDCP Ready Video Card. The Asus fan was too noisy for me. The Zalman VF900-Cu cooler significantly brought down noise levels. A fan speed controller allows fine-tuning of the noise/cooling ratios. Initially, I was a bit skeptical of the fan controller, but I've come to appreciate it. The best thing about this fan is that it's very compact, and allows SLI configurations in side-by-side PCI2 slots. This isn't possible with the Zalman VF700-Cu Copper Ultra-Quiet VGA Video Card Cooler. I have installed both the VF700-Cu and VP900-Cu and the VF700 seems quieter at stock speeds; but with the fan speed controller, the VF900 is the quietest. Both Zalman coolers kept my EN9800GT at 36 degrees Celsius.
Pros: - Easy installation - Compact design, compatible with SLI configurations - Very quiet - Good cable length - Use of speed controller is optional - The heat pipe design is very effective
Cons: - Expensive, relative to the cost of a fast video card
Would I purchase this again? Yes, and the VF900 is better than the VF700 due to it's smaller size and variable speed controller.
