Where are they wired to? Alternator size? Battery size?

id say yr fan is fkt
30amp blade fuse to blow straight away
u must be running a fan from a house a/c unit hehehe

as a rule of thumb and most do not do this properly and to this safety spec

any fan 14inch or bigger i run

5mm wire whihc is rated at 25 to 30 amps from battery to fuse
never use a normal blade fuse even if its 30amp as it might not blow
but it will eventually melt and cause issues
i use the pink 30amp slow blow fusable links and use a female fusable link holder(2 pin)
as the 30amp pink fusable links push directly into them
make sure u use the bigger terminals too to suit the 2 pin plug and bigger terminals that the fusable link takes
its not a nice looking fuse holder but it works better than a crappy normal blade fuses they r ok on most stuff but not for big thermos

then run 5mm wire from fuse to relays and then 5mm from relay to fan power
then 5mm from fan neg to a good ground

another rule of thumb ive been told a 30 amp fuse will not blow when amp draw gets to 30 it has to be alot more so a typical 30amp fuse might blow when it gets an instant 40 amp never tested it but an old auto elect told me

unplug yr fan and if the fuse does not blow then yr fan motor is yr problem
its very common especially on davis craig fans thats y i try to only use
spal fans
