Fan issues - noise unberable - mbpr

Hello,

I'm having serious problem with fan speed/noise. Without any hard CPU usage (less then 20%), CPU die - digital is always very high and, I suppose, put the fans so high that the noise is unbearable.

I already bring my mbpr at the apple store, SMC reset ran twice and the Hardware test gave no error. They recommend me to change my 2 fans (around 90$) but it did not resolve the noise issues...

Product specs :

Retina, Mid 2012

Processor 2,6 GHz Intel Core i7

Memory 16 GB 1600 MHz DDR3

Graphics Intel HD Graphics 4000

Software OS X 10.9.3 (13D65)

I don't have the Support Coverage, that's why I'm asking you for advices or any idea how to solve this problem, without high cost.

Thanks in advance for your reply,
