Noisy fans on iPC

We have had our iPC a couple of years now. The console is great - BUT - the fans on both PSU and CPU are really anoying.


Is there any PSU that is passive cooled, or that have a fan that not sounds so much, that works with iPC.


Also, the CPU fan is really anoying. Any suggestion on a fan that is small enough to fit in iPC.
