I was on my wifes eMac tonight and I couldn't help but notice it seemed noisier than normal. I've not noticed it like that before but it seemed to be pumping a lot of heat from the back, is this normal at all? It could be sue to me using my near silent iMac as the emac is only lightly used by my wife so I hardly hear it. If they're normally noisy I will stop worrying! Thanks.
