Well, on the 1271Q, which I imagine is the same as the 1272Q there are 2 fans on top (right and left) one located at the middle rear on top (very small fan) two at the rear (right and left side) and I believe 2 or 3 up front near the power supply board below the lens. I would imagine the noise you hear is from the small rear fan that is used for air flow through a heat sink. On one of mine it occasionally makes a noise and when I called Sony parts, if I remember correctly, that one was around $80.

I had the small 40mm fan fail, it was located at the rear just behind the heatsync, hidden behind the infrared receiver.

This fan makes a lot of noise when it failed, like a plane was flying right over my house. This little fan makes more noise then you think it could possible make.


The way to check it is to place you finger near this fan and feel if it fibrates a lot.


Anyway I replaced it with a fan of the same size, from an electronics shop. It was much cheaper then a Sony spare part, but you need to disable the fan sensor, which you may not want to do.
