IC7-MAX3 fan loudness?

How loud is the OTES-fan in the IC7-MAX3? Does it run evenly all the time or is it temp-controlled? I have watercooling on my cpu/northbridge/gpu, so the OTES-fan would be the only loud fan in this case.

Yes, it runs all the time and it's temperature controlled if you switch it from BIOS (FanEQ) or if you're using AbitEQ(Smart Fan Enabled). And how loud, it depends what you can handle 40x40mm fan running ~5000rpm. And if you didn't know it runs with same speed as Northbridge fan.

The northbridge fan&sink will come off eventually, when I install the watercooling set. I'm just worried that it's required that the OTES-fan is at full speed when you overclock, as I'm going to (striving for 4GHz). The components will heat up pretty much, and then the fan should be able to pull out all that hot air inside. If not, the system becomes unstable, correct?

Maybe the IC7-G would be a better choice for me, since it hasn't got the OTES-sh*t?

When I first turned it on I could hardly even hear it. Then again I definately don't hear it now. LOL

oh douh, you don't hear it?! Personally I can say it's too loud for me. I use FanEQ to get CPU, NB & OTES-fans running at 70% speed when CPU temps are below 50, after CPU temps pass it they're all running at 100%.

And Solari, if you're worried about that so much, buy IC7-G and passive heatsinks
