A lot of Emachines, Dell, and HP epecially; the fans come on when you power up your computer, then shut off. They are triggered by a thermostat. Once your PC gets hot enough, like when you're playing games that take a lot of CPU usage they will kick in, usually speed up. So if your fans keep turning off, there is nothing to worry about, just your CPU hard at work ;)

Does a glock have safety?

Yes and no. The Glock does not have an external safety that is operated by the shooter. The safety mechanisms are controlled by the trigger, and function when the trigger is pulled. If the trigger is NOT pulled, the safety mechanisms prevent the firing pin from moving forward and striking the cartridge. However, if a Glock has a cartridge chambered, AND you pull the trigger, the gun WILL fire.
