Depends on the pump, and it being a pretty weak unit to begin with with very low pressure and flow characteristics(the thin tubing doesn't help either).....Don't confuse this with heavier duty pumps that can output 2~3 gallons a minute like heavier duty pumps can and 20+ feet of head pressure, and using 20 watts of power for the motor itself when running at it's max speed.
Setups like the above picture can match the best aftermarket aircoolers but be more silent and that's it.
