Ok had my grid+v2 for about a month now and have been very impressed with it but occasionally the front two fans(viper 140mm) seem to spin up for no apparent and sound like a jet engine. Any ideas why this is happening? They are set at 30% which gives approx 650rpm.
 
I just installed mine this morning.

My fans will just ramp up and down every three seconds. I'm sure its something to do with Minimum speeds but considering they are all PWM Fans i'm a bit confused.

More research this evening. If I find anything out I will let you know.
 
That guys problem is identical to what I sent to NZXT. Thanks for that, i'm using Noctua's too. S12Bs Redux 1200.

My two SP120s don't do that though. They spin at 1200rpm which is about half capacity.

Ill try messing around with spin speeds and see where that leaves me.

Just a FYI the Noctua's I have at full whack only make 18Db. Even if I had to run them at max I doubt they would be abnoxious.
 
No problem hope you sort it :). I've upped my Vipers to 35% ~ 800rpm and can't hear any difference so hope this sorts the revving up problem.
