How much noise do the imacs make?

I bought a macbook pro with retina display(with maximum settings availabe) a month ago and tested some intensive games such as skyrim and battlefield 3.
The frame rate was fairly endurable for me, but what I could not tolerate was its annoying noise which started once I launched games. I do know apple did a lot of work do deal with noise on MBPr, but it kept me annoyed during the play.

I would like to ask Imac users if your imacs make as much noise as MBPr when playing high-spec requiring games. Considering the thinness of newly reported imac, how do you think apple took care of noise? especially with GTX675mx and 680?

Recently I've been playing Borderlands 2 on a Mid-2011 (3.4GHz i7, 24GB memory, 256GB SSD+2TB HDD, AMD RADEON 6970M 2GB). The GPU is also having to deal with a 27" LED Cinema Display plugged into one of the Thunderbolt ports. I have the CPU fan speed baseline increased by 200rpm, and the GPU (optical) fan speed baseline increased by 400rpm, and they have a more aggressive temperature ramp.

I have the game running at 1920x1080, 16xAF, FSAA, and High Quality for everything but PhysX. The game averages 60fps, and the iMac is effectively silent even after a 6-hour session... including while playing videos in YouTube (in Chrome) while playing the game and maintaining a VOIP session over Skype.

If it makes noise, you have to put your ear next to the vent to hear a faint whisper.

I have to agree, the noise of the fans even when they are ramped up during GPU intensive activities is well with acceptable limits.
