SMC fan control - changing lower temp threshold

    I'm using a late-2008 macbook5,1 2.0GHz Intel Core 2 Duo with a SSD and 8Gb RAM. It's an older model, works fine (Snow Leopard), but sometimes the CPU temperature gets a bit too high (I'm one of those people who worries too much). I cleaned several times the fan and I'm planning to get a new one (the old one is a bit noisy at low revs). The fan starts to really ramp up once the CPU temp reaches nearly 90degC. I don't understand why there is no better anticipation of the temperature rise. I mean if both cores are running at 100% and the temp is rising the computer should increase progressively the fan speed to avoid high temp and not to wait until it's reached. Is there a way (that actually works aaand is safe) how to modify the lower threshold temperature or how to set up a steeper ramp to better anticipate overheating? Perhaps a X11 command or istat pro/menus or menumeters etc.
    Thank You

    There are some apps that allows you to do this...

    Hello asriznet,
    yes, I know about SMC fan control, but I've read many threads about is, that mentioned severe issues. I would rather be tempted by Fan control or Macs fan control. the former isn't very recent though. Does someone have an idea which one does better fan curve modification? And what about istats menu 4?
    thank you
