[TenTec] Fan For Titan 425

[Gary Hoffman]

Yes....and the thickness is especially important.  Other things being equal,
and lacking specific performance specifications, note that the thicker fans
are capable of more pressure at a given flow.  You want to have enough
pressure to force the air through its cooling path.
