Zalman VF900-Cu GPU Cooler Review


Installation of the cooler is relatively simple once you have the original cooler removed. The stock cooler is very simple to remove and once removed you will need to clean off the original thermal paste. I usually use a bit of alcohol on a tissue or lint free cloth to remove the old paste.

Once the GPU is all cleaned up you are ready to apply a new dab of thermal paste, however I choose to use AS5 (Artic Silver 5) instead of the supplied thermal compound. It’s always good to make a dry run or pre fit the cooler prior to applying the new thermal compound, just to ensure a proper fit and it usually helps me to have a much nicer, cleaner and easier installation once the thermal compound has been applied. The first thing that will need to be installed is the fancy little blue ram sinks. These ram sinks are more than simple to install, they have an adhesive backing, which a simple removal of the protective film and the ram sinks are ready to be press onto the ram. One thing I found out is that it seems to help if once you place the heat sink on the ram use a slight twisting side to side motion while applying pressure, seems to make the sinks stay on a bit better. The reason for eight ram sinks is so that they can be placed on the backside of the card and then the remaining four on the front side of the video card ram.

Now comes the exciting time of the actual heat sink/ fan installation. Once again installation is a breeze and the unit is easily installed with-in a couple minutes, just don’t forget to add the thermal compound prior to final installation. First, you will need to determine which holes on the mounting bracket you will need to fit your video card. Once that’s determined you simply screw in the threaded nipples, slip on a rubber o-ring, then place the unit onto your video card lining it up to the factory holes.

Once you have the unit placed on your video card you will need to either lay it flat fan side down or just simply hold the fan/ heat sink firmly while being able to access the backside of the card. Place one plastic washer on each screw protruding through the card, then add the spring and finally screw the holding nut on. It’s best to get both holding nuts started first and then tighten each one back and forth to allow for even seating of the heat sink to the GPU.

The only thing left once you actually have the cooler installed is to re-install the card into your pc, re-connect the power supply cable (if needed) to the card, connect the fan mate 2 and fan wires to an appropriate power source and fire it up to enjoy cooling of the new Zalman VF900!
