well thats nice to hear the volt meter isnt a big deal...its been driving me nuts. So one 12 inch 1550 cfm fan wont cool my truck. I have a brand new radiator in it and it is a 5 speed.I was thinking about one of those flex fans they are like 50 bucks and also they have two 10 inch fans for about the same price. One reason I am thinking about doing this also is when I go to speeding up or starting off you can hear the stock fan just a whirring. Not a bad sound like something is broke just sounds like it is take all it has to spin it
