Slim PSU rev.2 noise

My PSU details are as follows....

MODEL: CPA 09-011A
REV: 03
POWER: 135w
VENDOR: E143709
MS P/N: X818314-005

 

The problem is that the PSU after a few minutes creates a windy whine that is annoying.
It is not so much a problem when the sound is on loud, but during movies from sky player, and you have quiet parts the whine is distracting and noticeable.

I have a friend who has Rev: 02 and although the windy noise becomes similar there is no whine.
With both Rev: 02 & 03 the PSU noise is distinctively louder than the console fan.

Some people online have suggested that either Rev:03 used cheaper components, or that some PSU are faulty and don't auto adjust fan speed.

 

 

 

I am hoping that there are newer revisions that do not suffer from this whining. 
Anyone know what the latest revision is?
Anyone know if / why there are newer revisions, and are any quiet?

Its more of an annoyance than anything else.  

Surely the PSU being louder than the CPU is an issue.

I'd just like to know if this is a known complaint and that new revisions address the issue.
