I've been following thread due to the fact I also use the Artic Cooler on my
6800GT, I used to use one on my 9800 Pro where IMO the cooler seemed a little
better than the NV5 version, but that's probably because of the different
chipset etc.
I only fitted my NV5 a few days ago having purchased the 6800GT last week,
because the one on the 9800 Pro worked so well especially with regard to
dropping noise levels it was really a must have when I changed cards.
It dropped my core temperature from around the 50c mark down to 47c at idle, not
a big drop, but any reduction is welcome, and noise levels are certainly a lot
less than the original cooler.
My system is fairly quiet, I have plenty of fans, 2x80mm blowing in at the
front, 2x80mm drawing out at the rear, and 1 80mm blowing in at the side,
besides the Enermax P/supply doing its job, all the 80mm fans have been slowed
down using resistors... I hate a noisy system!
I do notice because the Artic Cooler is plugged into the default card power
socket that the slight 'PWM' speed control pulses are just audible in the form
of a very slight ticking.. this is typical with electronic speed controls and is
not a fault in any way, but a little annoying just the same. That's one of the
reasons I stopped using a Vantec fan speed controller because of the slight
ticking noise which was induced into the fans. I had been considering powering
the Artic Cooler fan from the main 12v connector and slowing it down slightly,
but as the ticking is only barely noticeable I'm probably being rather fussy.
))
I can feel air coming out the rear of the Artic Cooler so it is extracting warm
air out the back. What I find strange is... on looking at the picture on the
Artic Cooler website which shows the fan rotational direction etc. is that one
would have expected the blades on the fan to have been the opposite way round to
get maximum airflow... very weird. They are the designers and should know best.
One thing is certain you cannot change the direction of a PC by reversing the
power feed wires. All PC fans are electronic induction pulse motors, ie. they
have no brushes... so its not possible to reverse them, and because you cant
turn the Artic Cooler fan over... as one other poster put it the whole subject
is totally non relevant!
