    Hi, so i've bought my macbook last August and I must say I've had no problems whatsoever with it so far :)

    BUT while running the SmcFanControl app today I noticed that the rmp of my left fan harshly dropped while the right one was still running smoothly.

    Normally they both spin at an average of 3000 rpm but the left one only makes up to 250 rpm anymore, even when I run an app like final cut pro.

    I wanted to ask you guys if this is normal. I fear that it might need replacement but you never know.

    JronMasteR is right. Reset the smc.
    If it doesnt work, take it to apple.

    All I've done was take one of the newer vacuums and vacuumed the back every few days if I have used my MBP heavily for whatever reason. I am not sure if the very faint rumble is the fan(s) whirring arround or what.

    The SMC control is set at the lowest setting of the exaust fan set at higher RPM, btw. Anything else I should be doing? Right now, it may or may not make a difference, but I am sitting by an open window and the air is circulating arround. :)
