Like many modern nVidia cards, there are four spring-loaded screws on
the back holding the cooler in place. The PCB is roughly 21.9cm in length.
The center heatpipe visible above juts out past the edge of the card
by approximately 2cm.
The base of the heatsink is very typical modern GPU heatpipe coolers.
The heatpipes are soldered to a very thin copper base.
The black half of the heatsink is solid on the underside, so air cannot
pass through it vertically. Two of the heatpipes are flattened and soldered
to the underside of the fins.
Before passing judgment on such an unusual design, we wanted
to know exactly what their motivation and inspiration came from. The official
press release had several interesting passages detailed below.
| "The V-Cool Heatsinks
super racing car engine design stands as a testament to the unique and
high-precision craftsmanship from ASUS; and combines a stylish outlook
with powerful cooling performance"
||Creating a heatsink
that looks like a race car engine is nothing short of an engineering marvel.
However, while it certainly looks interesting, we have to scoff at it
being described as "stylish."
|"Phasing in the V-Engine
concept* (*A V-Engine means that the pistons are aligned so that they
appear to be in a V when viewed along the axis of the crankshaft.
The V configuration reduces the overall engine length and weight compared
to an equivalent straight engine.), the ideally arranged V-fins dissipate
heat evenly with a minimum of space required"
||We have to give them
points purely for committing so strongly to the engine analogy, but none
of it seems to have any relevance to heatsinks.
|"...while the high-density
zipper array fin module utilizes the Intercooler technology** (** Intercooler
Technology means that air flows over the outside of the intercooler's
fins, which in turn cool the air inside the intercooler) to maximize the
surface area exposed to the air to help heat dissipation.
|| By making the fins
at the back form a "zipper array" air passes not just over the
fins, but through them. They're assuming there's enough airflow inside
to keep it from just lingering.
Overall, we were more confused after reading the press release
than before. As far as we can tell the black portion makes little direct
contact with any of the heatpipes or the copper base. We have many unanswered
Why does the V-Engline even exist?
Why use two separate sets of material?
Why are the fins not all the same thickness?
And most importantly, why are all the fins pointing
in different directions?!
With such a convoluted form, it seems to us that the V-Engine's
only function is to keep the entire assembly from falling apart and to look
"stylish." Never mind; the proof will be in the cooling.
