00:00:00.719 --> 00:00:08.800
Now, I'm going to have to talk over this full speed fan. Right now, I have the

00:00:05.120 --> 00:00:11.040
fan manually set to uh Okay, you can't

00:00:08.800 --> 00:00:14.200
really tell, but I unchecked auto. I took it to the very end and then I

00:00:12.400 --> 00:00:19.279
clicked apply. And that's how loud it is. This

00:00:16.640 --> 00:00:22.560
thing is loud. Um, so I'm going to have to talk over it a little bit, but I want

00:00:21.199 --> 00:00:26.960
to show you guys something really neat. So, I turned auto back on. And watch

00:00:25.039 --> 00:00:34.559
what's happening to the fan speed right now.

00:00:28.720 --> 00:00:34.559
It's going down by one percentage at a

00:00:37.559 --> 00:00:41.680
time. And if you listen to

00:00:56.120 --> 00:01:03.359
it, it's a very very gradual progression

00:01:01.520 --> 00:01:07.760
in terms of the noise level. Now, it actually does the same thing when the

00:01:05.199 --> 00:01:12.080
fan speed is ramping up compared to previous cards from NVIDIA as well as

00:01:10.159 --> 00:01:17.119
from their competition. So NVIDIA's added what they're calling adaptive fan

00:01:14.040 --> 00:01:19.439
control, which is a way of saying that

00:01:17.119 --> 00:01:24.159
instead of the fan speed going from, you know, idle, so so pretty much silent on

00:01:22.400 --> 00:01:29.439
almost every NVIDIA card for the last couple generations

00:01:26.520 --> 00:01:34.880
to as soon as you start gaming, you'll actually see like look how gradual that

00:01:32.159 --> 00:01:39.680
ramp down is of the fan speed once the card realizes that it doesn't need the

00:01:36.799 --> 00:01:43.200
fan to go as high as it is. So, why don't we give you the opposite example

00:01:41.280 --> 00:01:48.320
really quick here and I'm going to fire up Firmark in extreme burn mode and show

00:01:46.240 --> 00:01:53.200
you just what happens with that fan speed right

00:01:50.759 --> 00:01:57.240
there. Actually, here to speed things up a little bit, I'm going to go ahead and

00:01:55.360 --> 00:02:02.719
cover the intake of the fan with a piece of

00:02:00.360 --> 00:02:07.560
paper. So, there now you can see it's finally going up. So, it's it stepped

00:02:04.560 --> 00:02:10.879
itself up one and then

00:02:07.560 --> 00:02:10.879
2%. And then

00:02:14.440 --> 00:02:18.000
3%. 4

00:02:19.480 --> 00:02:26.879
5 6. So, this allows it to be a lot

00:02:24.400 --> 00:02:32.319
smarter about how much noise it's outputting depending on the amount of

00:02:29.680 --> 00:02:37.200
load on the GPU. So, I personally think this is pretty cool because it means

00:02:34.480 --> 00:02:42.319
that you don't get that uh that obnoxious uh uh up and down movement of

00:02:40.640 --> 00:02:45.280
the fan. Like say you're in a you're playing a game where there's a certain

00:02:43.760 --> 00:02:51.040
intensive part and then there's a less intensive part and you hear the fan

00:02:47.800 --> 00:02:53.040
go. or if it's at that borderline where

00:02:51.040 --> 00:02:57.599
it's uh it's it's just like let's say the uh the fan profile on the card is if

00:02:55.280 --> 00:03:01.280
it gets to 80 degrees then the fan ramps up to cool it down and then it cools it

00:02:59.440 --> 00:03:05.920
down to 75 but then it heats back up to 80 and then it and so you have that that

00:03:04.000 --> 00:03:12.120
constant up and down up and down motion. Well, this will make that kind of uh

00:03:08.800 --> 00:03:14.239
well adaptive cooling almost

00:03:12.120 --> 00:03:18.920
unnoticeable unless you got your ear to the card. So that's pretty darn cool.

00:03:20.159 --> 00:03:27.239
So, just for context, here's the same demo with the GTX 480. So, I'm going to

00:03:25.200 --> 00:03:33.120
turn on auto fan control. And boom, it's quiet. Okay. And

00:03:30.959 --> 00:03:39.440
then if I go ahead and do what I was doing before with the 580, turn on firm

00:03:36.280 --> 00:03:42.159
mark, cover up the fan, you're going to

00:03:39.440 --> 00:03:47.480
see that even though it shows that the the fan speed is going up, you know, one

00:03:44.640 --> 00:03:52.879
lone percentage at a time here. I'll wait till it uh starts

00:03:50.640 --> 00:03:56.959
going here and I'll put the camera a little closer. You're going to be able

00:03:53.920 --> 00:04:01.400
to hear the fan ramp up really fast,

00:03:56.959 --> 00:04:01.400
kind of like a a jet taking off.

00:04:44.960 --> 00:04:52.320
So, contrast that with how slowly and smoothly the 580 fan ramps up and you

00:04:50.479 --> 00:04:57.520
have yourself a very good reason for NVIDIA to implement their new adaptive

00:04:54.639 --> 00:04:57.520
fan control.
