Kad PSU nesisuka ventiliatorius, tai gerai. Bet tada klausimas is kitos 
puses - kas pasalins siluma is dezes vidaus? Kitas ventiliatorius imontuotas 
korpuse? :)

Quiet, efficient operation
80 PLUS Platinum efficiency and Zero RPM Fan Mode mean that at low to medium
loads, the fan doesn’t spin at all. And when you do push the HXi hard, the
thermally controlled fan spins only as fast as it needs to.

But that’s not all. It’s quieter than most PSUs when the fan’s not spinning,
too. The HXi is built with capacitors and other internal components
specially selected to reduce coil whine and other electronic noise.
