What causes a whining noise when accelerating?

This is most noticeable when outside temperatures are lower. Only notice when accelerating.

Candidate diagnoses offered by " know it all" friends are as follows:

(i) idle tensioner pulley is bad. Estimated repair $350

(ii) power steering fluid is low

(iii) power steering pump is bad. Replace

(iv) transmission is going out (don't think this is it. Same noise occurs when in neutral and engine rpm is increased)

What do you think?

If you only hear it when you accelerate, my first guess is PS pump. Does it make any noise when it is idling?
