Based on limited personal experience and what a friend says who is ran a 
private repair business the stock AMD CPU heat sink/fan combos are meant 
to be meant to be tossed: they barely cool a lightly working CPU.  With 
the AMD FX-9320 CPU/heatsink combo my 'workhorse' computer (not the 
Backend) was idling at about 130°F and eventually was overheating and 
shutting down while doing overnight backups.  Not good.  Replaced the 
heatsink and fan with a CoolerMaster EVO 212 and I've gotten down to the 
upper 80's.

As for the sound level, I've got a couple of CoolerMasters around the 
house and essentially silent.  I think the case fans are noisier.  Check 
the dB ratings: lower number is quieter.  New fans can be a lot quieter 
than the ones you are using now: engineered with less turbulence while 
increasing air flow (oh yeah: for the cfm value  higher is better).

Be sure to remove the heat!  A single case fan might not be enough.

You might also wish to monitor your temperatures: here I use a utility 
called 'psensor'.
