adding fan to audio system

I want to add a fan to my system.  I have some questions (below the following description).  Here's the one I'm looking at:

RoHS Compliance : Yes

Description

• FAN, SILENT, 92MM, 12V, FAST SPEED
• External Height:92mm
• External Width:92mm
• Depth:25mm
• Current Type:DC
• Supply Voltage:12V dc
• Current Rating:140mA
• Flow Rate:44.5cu.ft/min
• Noise:27dBA
• Connection Type:Wire Leads
• Series:San Ace
• RoHS Compliant: Yes

I figured I would use a relay off the system's remote turn-on to activate the fan.

I have two questions:

 - 140mA is relatively nothing as far as power draw, correct?  (That's my really dumb question)

 - Will the fan, CAN the fan, introduce noise into the audio system?  (Not-so-dumb question, I hope)

Thank you in  advance.

Q1 yeah its not much, good move using a relay,

Q2 theres no reason it should introduce noise into the system as long as the connections are GOOD pwr and ground

Fans can introduce noise into your system.  If it does give you problems, parallelng a 1000 microfarad capacitor across the fan will eliminate the noise.  As a general practice from the days of remote circuits of radios not having protection from overcurrent, I always use a relay.  Remote wire of radio to the coil of the relay and to that connection only.  Have the relay power every remote wire and fan in the system.  This way if yoiu have to add the capacitor to combat the noise, you will not have to stress the remote circuit of your radio to charge the cap everytime you power the radio on.  Install a diode across 85 and 86 of the relay.
