my fan switch went out, so i'm replacing it..

called the acura dealership today for the gsr switch..comes out to 55 bucks w/o taxes included...i know you gotta pay to play but that is expensive just for a switch..

anyways point is i was thinking of mind as well putting out that much cash, i can get a mishimoto fan switch for 35 bucks, after some research of the team integra and other forums they said it could cause your car to run at too low of a temperature maybe by like 10-15 degrees?

i'm planning to run SS headers, Dual core Mishimoto radiator, and oem thermostat with maybe the mishimoto fan switch

would i run into any problems with getting to the proper temperature daily driving it?
