You'll have to get on your knees and clean this out every now and then. You
wouldn't want dust accumulating there!
The huge mess of components that has been at the end of high-end NVIDIA cards
has slowly developed into a seemingly well organized line-up.
The back plate not only cools the memory modules, but it also helps to secure
the massive cooling unit on the other side.
The cooling unit is a very interesting device. Not only is it paired up with
the tallest GPU heatsink I've seen, but the manner in which it operates is
rather interesting to. But before I get to that, I must say that the fan is a
very quiet unit. A few minutes after the testing session, the GPU was resting at
a cozy 35 degrees C, just 6 degrees above the ambient temperature. I can barely
feel the fan blowing at all, and yet the heatsink is rather cool as well. The
NV38 definitely runs cool, and that's a step in the right direction for these
high-end chips. The cooler the chip runs, the higher it'll overclock :)
The air is pulled in across the heatsink, maximizing the contact area to cool
off the GPU. The fan then pushes the air towards the top at which point it
escapes through the funnel and out of the case. So not only does it cool the GPU,
but it also helps to properly ventilate the whole system.
