This value is configurable per file system. It is set at install time but you can change it at will.
You can set it with tune2fs using -c count or -i interval. A machine that is often rebooted might do without the interval, and vice versa.
You can turn it off completely but don't do that unless you have reason to. Running a fsck regularnly brings a bit of peace of mind, especially if your file system has been through a lot of upgrades.
