Throughout the tests and benchmarks, we encountered no stability issues
despite having no fans cooling the card in an open air environment.
ASUS has done a great job in the thermal management on the N6600GT Silencer.
However, the impressive cooling solution does have some cons. Due to it’s massive size for the heatsinks, running 2 cards in SLi mode
becomes as quite a challenge on all boards except on ASUS motherboards. Although
ASUS has stated that the fins can be tilted but it is actually pretty rigid.
due to the size of the protruding copper fin portion. In the tests, we managed
to push both cards together, and fit the SLi connector. However, this can only
be done in a setup without a casing. A case setup would not allow the SLi
connector to be fitted on, without the PCI brackets getting into the way.
From the top view, it is clear that the copper portion of the
card, will get into the way with the usage of 2 cards in SLi operation.
From another view, this is how the cards look like when
placed together. While this picture is taken without the SLi bridge connected,
one of the cards is clearly slanted due to the copper portion of the heatsink in
However, in an open air environment, we were still able to
operate the 2 cards in SLi mode. With a hard push together, the SLi bridge could
still be connected. But however, if users wanted to have 2 of such cards plugged
in a case, you’re out of luck.
