sorry if this is not the exact forum but...it is about fan noise from my G5 1.8 duo. Normally it is not too bad though of-course still has to be housed away - a cupboard with a big window. However, when the fan goes into "hyperdrive" not even the cupboard can contain the noise. I should say the computer does this wherever it is located - we are not talking about location of computer here. Is there a solution - for example replacing the fan? If so what make/model etc. Have others working in audio experienced this issue? I work as a voice over using a combined studio and control room hence the problem.
