I just got my 2.26ghz phat mini in. Aside from being surprised at how big the power brick I like it... except the constant whirring noise coming from it. Actually, there are two noises. The whirring noise sounds like it's rotating going from loud to quiet to loud to quiet over and over. The other is a rather high pitched humming sound. Neither is LOUD but just hits a pitch that is extremely annoying and is always there. I don't think it's a fan issue, I updated fully and tried using SMC fan control to crank up the fans from their idle speed of 1500rpm to about 4000rpm and they got louder (obviously) but the hum/whir was still there. Any ideas? Seems like a hard drive thing maybe?
