fuse amperage when hardwiring radiator fans

[Jason Schymanski]

To those of you who have done it or know what is
required, when you hardwire your radiator fans to come
on, what amp fuses do you use?
I did this because I got tired of trying to find out
why they weren't coming on automatically.  This is in
a 91 SE-R with 298,xxx miles.

Also, I just got an oil report back.  the only thing
they pointed out was high lead (16ppm) and I guess the
normal is about 4ppm.

Thanks,
