For a relay most fans want a 30amp unless your running a super high CFM fan or your fan is starting to sh_t the bed. It's that initial ON spike that kicks the relay.
I have used that kit on a few builds, it is fine for most setups, just make sure your fan does not need more than a 30 amp initial draw. I'd also throw a spare relay in the glove box, most of these are chiniseium and while the larger percentage are fine you don't want a $5 part stranding you in traffic!
