    Any feedback regarding noise from the above doing general web browsing/downloading etc?

    if you dont put 3-4 videos to play its going to be almost noiseless. The fans will run at only 2krpm

    My rMBP is totally silent when web surfing and such. On occasion I've heard the fan a bit when streaming long HD video. But it's the kind of noise that I have to mute the video and not have my home A/C running in order to hear. The only time I hear a noticeable fan is when I'm doing batch tasks in Photoshop or Lightroom.

    I was wondering what clockspeed the 2.3 and 2.6ghz run at when idling? i.e. using speedstep

    Is there any difference between the 2.3 and 2.6? I was wondering about Fan RPMs/temperature differences.

    If the 2.6 is silent like you say I might just get that one.

    Temps will be the same, since the rMBP uses 45W TDP CPU's

    What about extra heat from the 300mhz bump which would mean faster running fan? It could be that the difference is minimal (if any)?

    +300MHz with the same TDP has a negligible temperature increase

    Would a 2.3 user download the following:

    http://www.eidac.de/smcfancontrol/smcfancontrol_2_4.zip

    And let me know idle fan RPM (no programs open)

    And also a 2.6 user?

    I will probably go for the 2.6 if they are the same

    I don't have an rMBP but I think the min fanspeed is 1800RPM (I think)

    SMC sets a new minimal fanspeed value, I guess you can rev it up to 2200RPM (which is what I do) keeping temps lower and decreasing heat buildup while maintaining almost the same battery life as 1800RPM

    rMBP...
    fan speed range
    left fan = 2000 rpm to 5900 rpm
    right fan = 2000 rpm to 5500 rpm

    When you push the machine really hard, it will get really hot, and the fans are pretty loud at max speed, but not annoyingly so, its not that big of a deal.

    Like all Macbook Pros, Apple makes it very slow to change the fan speed, and sometimes it gets very hot before doing so. I guess they assume most people don't do sustained hard work on the machine so that high temp will pass in a few seconds, so no need to spin the fans up. I don't really like this idea, so whenever I know I'm getting ready to push the machine hard, I just go turn the fans up higher myself with smcfancontrol, but most of the time just leave it at the normal 2000 rpm it runs almost all the time.

    OK Now I am confused

    3720QM vs 3615QM - one review had speedstep at 800mhz but showed a CPU-z picture of 1.2ghz.

    I dunno, but when at battery I always throttle my CPU down to 800MHz :p

    If you're not using windows, then you shouldn't worry about CPU clocks. OS X's CPU management is excellent and does not need to be tampered with
