Waloshin,
Sounds like a very interesting problem to which I would suggest the following simple but subtle solution. If you've got the technical wherewithal. It sounds to like you might just have the geek gumption for this.
Active Noise Cancelling.
You will need a microphone, an oscilloscope, a computer, some cardboard duct tape and a fan. You already have a computer, so you're already one step ahead. The microphone and oscilloscope are not strictly necessary if you want to take an experimental approach, so all you need to do is go out and find a fan.
Most of the noise is coming from the fan, so it will be easiest (and cheapest) to use another fan to generate the cancellation waves. You'll want a fan with variable fan speeds. Not just low, medium and high, but totally rheostatic. If you can't find one, you can make one by wiring a rheostat into the motor.
Ideally, what you need to do is draw a 3D sound wave map of your room. Sound bounces off of surfaces, so you want to hit every corner and see what the the frequency and direction are. You could cheat a little by doing only around your bed, but that will make it harder.
Set your fan on the other side of your bed as the server. Turn it on.
Now comes the hard part.
Stick the cardboard into the fan blades as it spins. You'll hear a loud flapping noise. This is normal. What you need to do find the right speed of the fan and the length of the cardboard to generate the correct cancellation waves. The cardboard is important. Notice how it generates a different sound as it goes in and out? That's the trick.
You'll want to do this with a friend, because different parts of your room will cancel differently and you may have to move the fan around quite a bit and you want it to be silent around your bed.
Try it out. Once you hit the right combination of location, speed and cardboard length to cancel the biggest waves around your bed, I'll tell you what to do with the sound map you made.
Of course, this is much easier if you have access to a flux capacitive oscillation overthruster to generate those standing pressure (sound) waves.
