PC issue

[castgold]

My fans used to ramp up constantly until I got a water cooling system for my CPU. I used to idle at 75*C, now it stays below 27*C.

Nvidia has a utility
That allows you observe & change a lot of system setting relating to voltages & fan settings.
Find the one for your video card.
Your system is stout enough not to need additional cooling, I sometimes run a Linux 'live CD' that runs on system memory & havent experienced any trouble playing any YT vids.

Good idea. Will do and I hope this helps with the fan.

He is complaining about the fan that is on the video card, not the CPU.

Now let me ask you something.

Have you ever known a graphics card fan to FIRE up and make excessive noise while watching a youtube video?

Everytime I have heard my fans spin up, I am fairly certain that they were my CPU fans.

You do not need a fan to watch youtube videos. Do you? I have never heard of a card overheating (in the past few years for sure) because of a youtube video. I can understand if the cpu has to execute some weird code from a webpage though and it spins up the cpu fan all of a sudden to keep the heat down.

Did I miss something here? If we are going at face value, I do not know of ANY of the fans that turn off and on. I look at mine and I see ALL of my fans spinning ALL of the time. they HAVE to spin, else the system gets hotter. So I think OP might be making a mistake.

Perhaps he can post a movie of a fan that is not spinning (b/o fan) or take some photos. Or at least clarify that the fan he is referring to is NOT SPINNING AT ALL unless certain things happen. Fans spin- it is what they do and I have not known any fans to NOT spin. Maybe it is some Dell or HP thing...

If he has a system monitor running and it tells him which fans are at high revs, that should tell him which fan is having an issue.

Agree, but some change the rpm as needed for noise abatement.

True, my Lenovo has a setting in the BIOS for performance or noise reduction, so does HP.

HP bios fan settings

He may have his set in quite mode & it throttles up under a demand.

You can disable hardware acceleration to prevent your video card from being used when rendering video. This will reduce the fan noise, but also potentially the quality of streaming video (depending on how well your CPU can handle the software based render load). You should Google for instructions on how to do this as it varies based on your operating system and/or video card. Include the OS version in your search, for example: Win7 disable hardware acceleration

OK....here's an update: I downloaded the latest drivers from nVidia. Re-booted and ran a couple tests. It seems the fan goes into overdrive (gets very loud) when watching a YouTube video in HD (720p) in full screen (1920x1080). The fan often gets loud half way through a 7-10min video watching either in Chrome or Firefox. BTW, downloading a video and watching it, the fan doesn't goes into hyper-mode. Which gets me thinking if the browser(s) is the culprit.

Not being tech minded, I wonder whether Chrome or Firefox buffers the video and that somehow calls on either program & Win 7 to work harder (I'm assuming the fan goes into overdrive because the CPU gets extra-hot).

Sounds fairly normal. And sounds like it's your CPU fan going bonkers. Unless you have a laptop that may share a fan?

Web videos/content uses the CPU(software rendering). So your CPU has to add that to it's list of responsibilities.

Download videos like avi or mp4 video are able to take advantage of the GPU to decode the video. Offloading the work from your processor.

One more think I just noticed (it is a Desktop PC). The fan will go into overdrive if the I initiate a re-boot or shutdown.

You can try a video player like KMS (the BEST one out there is version 3.6) err KM Player I think it is called. I say it is the BEST video player out of them all because it is quick, small footprint and does NOT need you to install any codecs since it has codec filters built in. Maybe get some plugins, but downloading codecs is a thing of the past now. The newer versions have ads in them, but version 3.6 will play a lot of stuff.

So what I would do would be to grad KM player and install it, then get a you tube video downloader, download the video and then play it full screen with your KM player and see how it works.

Also, I am special stubborn sometimes and based on what I see, you have not convinced me that it is the video card fan. I will take your word for it if you are there looking at it, but can you CONFIRM which fan it is that is making the noise? Run with your case off and when you hear the fan fire up put your finger on the hub a bit and slow it down and you should hear the sound change. Like I said, I am special stubborn like that. That would be nice if you would do that though.

[Bushwack44]

I'm assuming its the video fan because it occurs 90% of the time when a video is playing. Also, I'll give your suggestions a try.

Postscript: Lots of Malware/Adware on KM Player. I'd be in trouble if I didn't have Malwarebytes installed. It (Malwarebytes) blocked 4 url's KM was trying to send me to while watching a 6 minute video.

You can't assume it's the video card just because you're watch a video. It depends on Software(CPU) vs hardware(GPU) acceleration.
YouTube, flv, html5 is all software.

H.264, vxid, mp4 or mkv can be Hardware accelerated as well as software accelerated.

Just use VLC for your video needs. Good hardware acceleration support. I know because my CPU fan doesn't go crazy all the time.
