What are you using to actually control the fan? Please don't tell me you plan to use a manual switch on the dash for this.
I found a dirt cheap adjustable fan controller at Autozone for under $20.00 which has worked great for about three years so far. You will also want to use a relay to deliver power to the fan. If you don't understand relays, then research it because this is important.
Good luck.

He is 100% correct on both counts!!
1) Use a Relay
2) Use a Automatic thermo-switch

I am usuing an auto thermo switch.
I am also familiar with usuing relays from hooking up off road lights on my old truck... the directions say nothing about having to use one and the fan is only pulling 9 amps.. doesnt sound like a lot of power so maybe a relay isnt required?

I'm sorry, but I don't have a number for the controller, or a photo handy. When I found it, it was not out on the shelf, but behind the counter (so I had to ask for it). It is the only one that Autozone carries in that price range.
****, that was frustrating. Took the time to look it up (their website sucks!). The links usually don't work for something like this, so I'll also paste the info I got below the link just in case.

Your fan may only draw 9 amps when running but what does it draw on start up? That's the kicker. The initial draw to spin up an electric motor is often much more than it's running draw. That's what relays protect against as long as the power wire is from a good source. I wired mine into the 2nd gen under hood fuse box, with a 30 amp relay.

heres a link to the one i am using. i just quickly read the box of the fan and it said something around 9 amps draw but i dont know if thats during start up or when its already spinning...ill read it again though

Ultimate Fan Controller
If performance is more important than price -
I highly recommend the Flex-A-Lite VSC. (Part# 31165-VSC)
Operation:
One of the improvements of the Variable Speed Control is its soft-start feature that prevents the fans from drawing a large surge when they spin up. It's much less stress on the electrical system, especially with trucks using two large fans with a combined total of 5500 cubic feet per minute of flow!
- Also reducing stress on the electrical system, the VSC will not power up the fans for a 5 second delay after ignition.
- When the VSC starts the fans it powers them at 60% speed reducing noise and power draw. If the coolant temperature continues to rise, the VSC will increase fan speed gradually to 100% over the next 10 degrees beyond your calibration point.
- The air conditioner clutch will also activate the fans at 60% power unless coolant temperature is higher than the calibration point and the fans are already running at a higher speed.
- The VSC will continue to run the fans for up to 30 seconds after shutdown if the coolant temperature in the core is sufficient. (This feature will prevent post-shutdown boil-over in high-temperature applications.)
- The manual override ON input allows the fans to be turned on at 100% speed at any time, regardless of temperature or AC status, as long as the ignition is on. The engine does not have to be running. (This will be especially handy at the drag strip!)
- The manual override OFF input will prevent all other inputs from starting the fans. (The ability to disable the fans is a nice safety consideration if work must be done in the engine compartment while the engine is running. Electric fans can surprise you coming on without warning.)
Available at JEGS.
This is what I used before the Haltech controlled the fans.
It worked more efficiently with the variable speed, and the 30 seconds after shutoff feature.
