    1) if i use smcfancontrol will it disrupt the default fan controls? like having the fans speed up automatically when running intensive programs etc.

    2) since smcfancontrol allows you to control the fan speed, will this at all kill the life span of the fans? and what is the max speed the fans should be able to run? and will using smcfancontrol make the fans go faster then they are originally allowed to go?

    Yes and no... SMCfc lifts the lower limit of the fans, but if the temperature rises due to heavy load, the fans will still spin up.

    a) In theory, yes: all fans are designed to last a certain number of revolutions... the higher the rpm, the shorter the life spam. Higher rpm accelerates the wear and tear of the fan's mechanism.

    b) Each computer has a lower and upper limitation for its fans.

    c) No, SMCfc will adopt the limits defined by the computer's firmware.

    I recommend you use it: IME it's a good idea to keep your computer's temperature as low as possible. The only disadvantage of SMCfancontrol is that you have to define it manually every time you see the temperature rising.

    Another good and automatic solution is FanControl - this provides an automatic solution and threshold control. As far as I understand, it does let you define speeds outside the natural limits. A lot of users are very happy with it as well, check it out here.

    I have three questions regarding this program aswell...
    I have decided to use it because i was seeing broken textures in an old game(enemy territory)... even though i suspect that it was due to a corrupted map rather than too hot components.. the temperature wasnt above 65 degrees.

    1) will meddling with fan speeds void my warranty?
    2) Should i want to completely remove the SMC fan control , the default values are the lowest values supported by the program?
    3) Its recommended to increase fan speed before a gaming session?

    1* Who is going to know ??? Trash the App before you need to take it in to 
    2* Personal choice
    3* Not by  at least. . . . . . . . And they wouldnt recommend increasing the fan speed at all (or the default speed would be higher) .....

    Why would you increase BEFORE a gaming session?? Wouldnt you increase during play ??
