Really quick question but to rewire my fans, what relays r the best to use?

SPST = SINGLE POLE SINGLE THROW, ie a boggo std one very common, will have 30/85/86/87 marked on them on the terminals, get from any car shop, or scrappies.

nice 1, i know it may sound over kill but is it worth having a relay per fan?

-----------------------YES ----I USED TO RUN KENLOWS WHEN FIRST USED IN MOTORSPORT AND RELAYED EVERY THING!!!!!!!!!!!!!!!!!TWIN FANS TWIN RELAYS -GO FOR IT-------
MOTOR MANUFACTURETRS DONT USE THAT MANY, SIMPLY TO DO WITH COST .
JUST TRIGGERS REALLY-------------------

I suppose double redunddancy is a bonus, ie if one packs up you still have the other one, but they still rely on the ONE trigger, ie fan switch so unless using another I would not bother personally, just use a quality relay.
