This is a common misconception.  The Hash: SHA1 line is part of the
PGP signature.  It has no relation to the sha256 checksum data in the
*-CHECKSUM files.  https://fedoraproject.org/verify has details on how
to verify downloads and does point out that sha256sum is what should
be used.

We're discussing ways to make this clearer in future releases so that
folks don't mistake the PGP Hash header as the hash used for the .iso
images.
