Possibly someone switched the SilentFan II with V7+ fan that just has a temp sensor hanging out the side.
Or the site you saw it at was just mis-labeled. Beware that may be a ploy to get you to buy it and you find out after you've opened the shipping package (and void the warenty) that they sent you an over-priced V7/7+

dude, the Volcano 9 comes in one version - and one only. Anyone advertising the Volcano 9 as "Volcano 9 silent" is just advertising the fact that the fan it comes with (SmartFan 2) has a rpm controller on it, so that you can choose how fast the fan is going, and therefore the noise emitting from it (but the temperature of your CPU is affected as well, don't forget). basically , its the same thing, and whoever is selling it for the cheapest is where you should grab it from

Also, check the website... there are at least two versions of the V9... one has a bunch of lights in the fan... truly weird.
The problem remains... slow down the fan and things heat up, causing the fan to spin faster... you end up listening to it anyway.
AND... I really would not suggest trying to thread wires between the CPU and heatskink, it could tilt the chip causing a failure in the thermal conductivity between the heatsink and cpu. It could also cause bad connections between cpu pins and socket points. If you gotta put the sensor someplace, put it in the center channel where the spring clip is.
