Is my graphics card faulty? Video + audio links inside.

post #1 of 3
Thread Starter 
Hi,

Last night I noticed that an intermittent 'blowing' sound was coming from within my computer. I inspected it properly today and found that the noise was being produced the fans on the GPU cooler. The graphics card I am using is the ASUS HD 7850 DirectCUii V2, which uses two fans.

I was wondering if someone could shed some light as to whether the following is normal, a BIOS/software issue, or whether I need to contact ASUS regarding an RMA.

Firstly, whatever is going on, it seems related to the Display Sleep function in Windows, and whatever controls the fans on the GPU cooler.

The issue is basically that intermittently, both fans will exhibit a 'surge' in speed, while the display is asleep. What's more, is that if the computer is completely idle when the display goes to sleep (no downloads, no nothing. just your usual windows background processes) the fans turn off all together, but still spin up intermittently. If, however, the computer is occupied with something, the fans don't stop spinning completely, they seem to remain at idle speeds, but when they 'surge', they spin faster, a thus are fairly audible. It is almost like both fans are receiving a 100% fan speed signal, but only for 0.5 seconds or less. They then return to idle speed/off.

I recorded a short video of when the display has gone to sleep from a completely idle state:

As you can see, the fans are still for a good 40 seconds, they spin up at about 50 seconds, and again at about 1 minute 10 seconds. This will continue until I move the mouse or press a key to wake up the display. They then spin up immediately and remain consistently at their idle speed.

The camera I used has a pretty terrible mic, so I used a *slightly* better one to capture just the sound of the fans 'surging' from idle speeds. At the time, I was formatting a large, but very slow, USB thumb drive. As mentioned, this is the same as when downloading from Steam. The fans will not stop completely like in the video, but will still spin up every now and again.

The 'surge' happens just after the 4 second mark.

There seems to be no timing regularity to the surging or stopping / starting.



Apart from this everything seems to be functionally ok. I've been playing a lot of Battlefield 3. Furmark runs without any problems.

Should the fans even be stopping completely? I'm not sure I've ever heard of this happening. And seeing as though they are inaudible, even under load, I don't see why completely stopping them would be necessary?

Many thanks for taking the time to read / download.

Are you sure? I would have thought so myself, but the fans spin up so inconsistently. It just seems like something is 'blipping'. I'm also certain that this hasn't been happening for the last couple of weeks since I have had my new system up and running. My computer is on a desk next to where I sleep and over many nights I've left it downloading, with the display going to sleep. Never heard anything like this until a couple of days ago.

I forgot to mention that the day after I noticed this happening, I had one instance where the monitor would not wake from sleep. No matter what key I pressed or how much I moved the mouse. I ended up having to restart with the power button. Could it just be a coincidence?
