Basically, whenever my fans start spinning, let's say more than 3000 rpm, my computer (2006 mbp) crashes. I only noticed this recently after thinking my computer was completely defunct. I turned it on one day and noticed one of the fans wasn't working (I use smcFanControl). My computer was functioning 100% for the first time in months. I didn't want to restart it, afraid that I would break my luck, but had to a few weeks later when I went on vacation. When I returned it was back to how it was. Both fans were functioning and it was crashing every time it was on for more than say, 5 minutes. It then occurred to me to turn down the minimum fan speed with smcFanControl (I only installed this to begin with because I thought my computer was crashing because it was getting too hot...it does get really hot.) So now, as long as my fans are spinning at a 2000 rpm my computer functions fine, but it usually doesn't last there long. I guess my question is why and if there is there anything I can do? I'm already planning on and saving for a new mbp, but I'd like to at least have this computer functioning until the refresh considering I've stuck by it for this long.
