Coolsonic CS1662K From
All Angles |
 |
The Fan: The stock YS Tech fan is 25mm in height and uses a
seven-bladed impeller. Since the fan only rotates at about
5200RPM (according to the spec sheet), there is no real need for a wire fan
grill. The fan draws power via a 3-pin fan header and supports
RPM monitoring. |
 |
Top: It is really nice to see that
the tip of every copper fin is razor sharp - meaning that air from
the fan will have an easier time entering the fins all the way down.
Square tipped fins can stall air as there is generally more resistance to
it passing. The copper skived fins are 0.45mm thick which is a little more
than we usually see (0.3mm). The fan is kept about 6mm above the tips of the
copper fins. The clip has no notch to keep if from sliding around on the
heatsink. |
 |
Side A: From the side we can see
that there are a total of 34 fins spaced 1.25mm apart. The CS1662K is not
the highest density Skive heatsink on the market, but
has a nice balance to it. To often we have seen skive heatsinks which have
been in use for a while completely clogged with dust bunnies. The wider
fin pitch should help minimize this a little. The copper base is 4mm thick, and 60mm
in width. Each fin is about 22mm in
height. |
 |
Side B:
The fan shroud is simply screwed
onto the copper skive portion of the heatsink. The retention clip is
tool based, so you will need to find a flat head screw driver before
installing the heatsink. As we mentioned before, there is no tab at
the fulcrum of the clip to prevent the mass of the heatsink from sliding a
little after installation. The two sets of skived fins are 28mm in width.
The opening for the clip is 6mm. |

Heatsink Base:
From this angle we caught all the sanding marks so
the base looks worse than it actually is. Coolsonic have machined the base
and then given it a light sanding. The copper is pretty flat, but domes very
slightly at the center. A curve is very slight, so a little thermal compound
will fill in all the voids. |
