Vantec VP4C7040 From All Angles
	The Fan: The seven-bladed TMD fans from YS-Tech are unique because the motor which drives the impeller is around the outside of the fan, under that metal casing. In standard fans, the motor is located at the center. The benefit of this design is that there is no dead spot directly under the center of the impeller - because there is no motor. The dead spot on standard brushless fans is usually right over the hottest part of a heatsink. The fan connects to a standard three-pin motherboard header and supports RPM monitoring.
	Top: The heatsink uses a small aluminum fan shroud to prop the TMD fan up 5mm above the tips of the fins. This space is important, and if you were to mount the fan flush to the fins you would probably find that temperatures rise slightly as less air being pushed down through the fins. The four sections of aluminum which come out from the central copper core measure just over 5mm. Flipping the heatsink over shows that the metal width increases to 15mm at the base.
	Side A:The clipping mechanism is tool-free and easy to operate. The heatsink uses a standard HSRM which is a nice change from those custom mounting solutions which seem to be gaining favor with some manufacturers.
	Side B: The fins only seem to take up 40mm of each side of the heatsink, but since they are nested the remaining area is not wasted by any means. The small fan shroud helps to keep the fan in place, and directs the exhaust air down through the body of the heatsink.
	Heatsink Base: The 25mm diameter copper core sits just proud of the aluminum base. The fins spread out from the core in a jagged pattern. The copper core is the only part of the heatsink which actually comes in contact with the processor and is very flat, but smaller than the core of a pentium 4 processor by a small amount.
