Now, I'm going to have to talk over this full speed fan. Right now, I have the
fan manually set to uh Okay, you can't
really tell, but I unchecked auto. I took it to the very end and then I
clicked apply. And that's how loud it is. This
thing is loud. Um, so I'm going to have to talk over it a little bit, but I want
to show you guys something really neat. So, I turned auto back on. And watch
what's happening to the fan speed right now.
It's going down by one percentage at a
time. And if you listen to
it, it's a very very gradual progression
in terms of the noise level. Now, it actually does the same thing when the
fan speed is ramping up compared to previous cards from NVIDIA as well as
from their competition. So NVIDIA's added what they're calling adaptive fan
control, which is a way of saying that
instead of the fan speed going from, you know, idle, so so pretty much silent on
almost every NVIDIA card for the last couple generations
to as soon as you start gaming, you'll actually see like look how gradual that
ramp down is of the fan speed once the card realizes that it doesn't need the
fan to go as high as it is. So, why don't we give you the opposite example
really quick here and I'm going to fire up Firmark in extreme burn mode and show
you just what happens with that fan speed right
there. Actually, here to speed things up a little bit, I'm going to go ahead and
cover the intake of the fan with a piece of
paper. So, there now you can see it's finally going up. So, it's it stepped
itself up one and then
2%. And then
3%. 4
5 6. So, this allows it to be a lot
smarter about how much noise it's outputting depending on the amount of
load on the GPU. So, I personally think this is pretty cool because it means
that you don't get that uh that obnoxious uh uh up and down movement of
the fan. Like say you're in a you're playing a game where there's a certain
intensive part and then there's a less intensive part and you hear the fan
go. or if it's at that borderline where
it's uh it's it's just like let's say the uh the fan profile on the card is if
it gets to 80 degrees then the fan ramps up to cool it down and then it cools it
down to 75 but then it heats back up to 80 and then it and so you have that that
constant up and down up and down motion. Well, this will make that kind of uh
well adaptive cooling almost
unnoticeable unless you got your ear to the card. So that's pretty darn cool.
So, just for context, here's the same demo with the GTX 480. So, I'm going to
turn on auto fan control. And boom, it's quiet. Okay. And
then if I go ahead and do what I was doing before with the 580, turn on firm
mark, cover up the fan, you're going to
see that even though it shows that the the fan speed is going up, you know, one
lone percentage at a time here. I'll wait till it uh starts
going here and I'll put the camera a little closer. You're going to be able
to hear the fan ramp up really fast,
kind of like a a jet taking off.
So, contrast that with how slowly and smoothly the 580 fan ramps up and you
have yourself a very good reason for NVIDIA to implement their new adaptive
fan control.
