That's what I'd expect after unplugging.
This is sounding like a bad coolant temp sensor. Test it or replace it before you do anything else. Read this post on how to test an engine coolant temperature sensor

It could have any number of problems first check fuel pressure, and then check to see if your getting proper spark from the plugs and wires. Also if there are any engine lights on get them check.

I had the same problem. I replaced the temp sensor and used a 2 pair of wires to test the fans. The fans were worked. The problem was the wire connection to the control module.

Check under hood on drivers side for relay/fuse box. They are labeled on underside of cover. If that turns up o.k. then I'd look at coolant temperature sensor.
Did you replace the sensor by the thermostat in the engine block or the one under the drivers headlight, There are two, the one next to the thermostat controls the temp gauge in the vehicle. the one under the headlight assembly controls the actual fans and is a electronic module. You have to remove the head light assembly to get to it.

That noise is probably the air injection system which is part of the emmision system. When it is making that noise, open the hood and determine where it is coming from, note if it is a mechanical sound, etc. The air injection if equiped would sound almost like forced air scaping somewhat like an exhaust leak, but less intense.
