hi im from sth.korea.
my eng. is kinda of shit.

i bought a 2018+ rc390 and felt its very hot in traffic jam so decide to upgrade stock fan to spal.

and then i decied to put 2 spal fan.

this is my question
i wonder should i reinforces the electricity like electrical relay or something else.

if no reinforcement causes any problems?

or just put two spal?

Not sure why you would want to put 2 fans?
One fan is capable enough to bring down the temperature once is switches on especially the Italian SPAL fan.
Some stunt riders make a forced cooling system by blocking off the radiator's rear and installing a 2x fan, but I do not think this is suitable for road riding.
As for your question about the power supply for 2 fans I have not seen any mention of this from people running two fans.
When worried about the coolant temperature there is a nice little device from Trail-Tech OTT that threads into the bleed plug of your radiator and indicates the coolant temp in degrees Celcius on a clear digital display, works well for me.
