Is that a dual blowing fan in your case...?Taking an exciting and different approach to card cooling, the developers at VIZO have thrust upon us, a new and exciting way to keep yer damn graphics card cooler (or any other card you may want getting cooler).
The Propeller Dual-Fan card is such a simple idea, I can't believe this is the first time I have seen something like this (ie. not a black dinky thing). The idea is that you simply insert the fan into an empty PCI slot in your computer/motherboard, placing it where you believe you need extra cooling. The dual fans then blow air directly onto the area directly beside the card in the hopes that added overclocking and heat reduction will occur. The fan gets it's power from a standard 12v plug (4 pin) that daisy chains anyone of the other powered items in your case.
Specifications for this card were found on the back of the box as well as at the website.

OK, so I pop open my case, and mind you, I already have three fans already built into my case (Antec P180b, go check out the review). I pop the card into the PCI slot right next to my graphics card and screw it into the frame and close up my case. Now on the outside the card features a sliding switch that runs anywhere between 2700 RPM to 4800 RPM. The switch actually has some meat on it and I liked the way the action on it worked. It's a solid switch that does not easily move on it's own (or by cord bumps). But I do question the idea to place the switch in the back. I would have thought ideally that a corded switch that came from around the back of computer would have been more effective as I don't normally make it a habit to crawl on the floor and adjust my fan speed. Actually, it would have been even better if they kept the switch as it is, but then added a plug in switch that the user could use if they so liked. Hmmmm.
Regardless, I actually saw no temperture decrease in my initial test, it could be because I have plenty of air flow going as it is. So I turned off the two fans in the upper portion of my case and then disconnected the Propeller fan from the 4 pin plug and let my computer idle for a couple minutes, then I began taking some readings:
