There are also additional types of 5 pin relays available (Time delay, diode, etc). So when you are replacing one, make SURE the diagram on the side of the relay, matches the one you are replacing EXACTLY!!

Well, hey dick, why didn’t you specify? :ROFLMAO:

Your first example doesn't have 87A. There is no NC to common contact. It's 2 87(s). It's just multiple outputs when triggered.

This is not ideal for running multiple fans.

30amp relay for two 6 amp fans??

I'm pretty sure he'll be fine.

Where the problem comes in is...

The wiring at the base connectors, that match his existing ones. Id want pins 30 and 87's to both be 10 gauge wires. This is easily fixable, if they don't come that way, with some female connectors and the correct gauge wires. 👍🏼

Could always go with a 40amp, or bigger relay, if needed.

It can handle the load, but if it fails, no fans for you. Best to split them.

10ga is overkill big time for 6a. 14 would be fine.
 
get the Hella relays with 1/4" terminals.

the same relays with the smaller terminals have a habit of melting the terminals, even when well below the rated load.
