User programmable temps for alarm and shutdown
Low fluid alarm
Copper waterblock with thermal probe Temp controlled fan speed (50% @ 35C, 100% @ 45C)
Fan override switch
Fail safe shutdown
Only thing I can think of to make it run quieter is to provide cooler air to the intake fan on the unit..Duct some A/C to that baby and see if it don't quieten down...The fans are making noise because the unit senses they need to run faster to cool your chip down..Providing cooler air to the rad. should take care of your issue..
What are your ambient(room) and system(case/mobo) temps??
