This looks like you are editing root's personal crontab using crontab -e. Your entry is on track, but the following:
0 1 * * * /usr/bin/yum -y update
What's even better is to write a shell script that downloads but does not install updates, and mails you if there is one (or just read the mail from cron)
You still have to manually update, but the packages are already downloaded - and you can opt out of an update if you don't want it - useful if you have non Fedora repositories in your yum configuration.
