Heatsink Design

The great thing about this unique heatsink are the heatpipes! You can see the twin copper pipes running out from the bottom of the heatsink to the top.

Aside from the heatpipes, the entire heatsink is made of aluminium, which makes the CoolGate significantly lighter than the all-copper heatsinks.

We removed the included 70mm fan, and found that it was made by Fanner. It is hardly surprising for Spire to integrate a product from their parent company into their cooler.

Flipping the heatsink over, the CoolGate appears to be made form two heatsinks welded together front-to-front.

Unlike the KestrelKing III, the CoolGate does not use skived fin technology. Therefore, the fin spacing in the CoolGate is not as close as that of the KestrelKing III. There are 64 fins in all on the CoolGate (yes, we counted ).

The heatpipes we saw earlier are used to transfer heat from the base of the lower heatsink to the upper heatsink. An interesting way to look at it would be to think of it as two heatsinks with their tops welded together and heatpipes connecting them! It certainly is different from the usual heatsink design, and is probably the reason for the narrow profile of the CoolGate.


Here's a preview of what we'll be inspecting on the next page - the (still-covered) base.
