How do you guys have your fans set up while gaming?

I started playing BF3 last night and as it's the first game that's probably challenged my computer, I wondered how fast my fans should be operating at. I have the triple copper heatpipe CPU cooler, Nvidia GTX670 and 3 case fans on my CM690 II Advanced, one at the front, one at the back and one at the top.

I have the CPU fan and 3 case fans 'Autotuned' on Asus Suite II and on standard mode my front fan runs at about 250rpm and the back fan runs at about 400rpm. The top fan does not operate in standard mode. CPU fan is at about 1000rpm.
When I turn it onto 'turbo' my front fan is about 300rpm, back fan about 500rpm and the top fan comes on and runs at about the same speed as the back fan. CPU is at about 1300rpm. I tend to keep it in turbo mode the most.

Now I know that when I press full speed, all my case fans go up to about 1100rpm and my CPU goes to over 2000rpm.

The question is, should I be trusting Asus Suite II to decide how fast my fans are running? When I first turned my computer on, the fans spun quickly (but still quietly) and my blue LED at the front was bright. After the autotune, my LED is always quite dull and the fan doesn't appear to be spinning much at all no matter how much stress I put it under. I don't know if this is just because I genuinely have a good case that's keeping all the components cool or whether Asus Suite just isn't picking up the correct temperatures which is resulting in my fans spinning slower than they should.

Should I uninstall Asus Suite and let my fans go back to normal? Has anybody else had experience with it? When my computer is idling I know the fans don't have to be running that quickly but I'd expect them to chirp up a bit after playing battlefield for a few hours. Should I just set them to full speed when gaming or will this damage them in the long run? I haven't been into bios to adjust anything as I've been quite trustworthy of Asus Suite but if the temperatures it's producing are wrong, then that means my fans are tuned wrong as they won't be kicking in when they should.

Or am I worrying about nothing? I have had no issues heat related so far but I don't want to be damaging my machine in the long run from something so preventable.

I use Asus suite to control the chassis fans and I set them on custom, it gradually increases from normal speed if the CPU goes above a certain temperature to avoid loud noise when just using the Internet or working. I do the same with the gpu.

You should be able to see a visual indication of the fan speed against temperature graph using ASUS Suiite and you can create a custom one if you wish (as Keynes has suggested). I personally just keep my fans on lowest speed setting from the Cosmos 2 Fan controller unless I notice my Pc getting warm or if I'm playing an intensive game/doing some intensive work.

I think the ASUS suite is ok for fan control though - you could always get a second program to monitor temps and create your own fan curve which might make you feel a bit better :)

I just use default settings. My computer rarely gets stressed so there is no need for me to fiddle.
