I have had an electric fan for about a year now and I personally think it's great, I'm looking for some help on trying to figure out why I keep having problems with 1/8 npt thermostats that are activated at 200 and turn off at 185, they are grounding switches to control a relay that then goes to the fan.

Seems the 1/8 npt spade terminal thermostats keep staying grounded or sometimes doesn't come on at all
I got a hose coupler from American volt and that has a grounding wire that is connected to the the body
Post up a pic. It sounds like the sensor may not be fully immersed in the coolent, and not getting a consistent reading. The best place for those sensors is mounted directly in the radiator.
OK that is what I was wondering.
How are you determining that the temperature sensor is bad? Could it be some other issue that is just masking itself and is making you think it's the sensor?
I've ran a few different electric fans and then types of sensors. On my old setup I found using a PWM worked better than one of the sensors like you're using.
I have a SPAL brushless now and am using their specific sensor for the brushless motors.
I mean it could be something else honestly but every time I have replaced the sensor it stopped having that problem and was normal.
Most PWM's aren't cheap but IMO they are worth it. And yes having a fan that comes on @ 50% and then slowly increases it nice.
This thread is a good read.

As of right now I have a three row radiator, if I do get a spal fan with a Dakota speed controller will there be enough room from the fan to the engine?
I have no idea. You'd have to measure it and see. You could just get a PWM... Why do you need to change your fan? And if you're getting a SPAL fan I'd go for the Camero fan talked about in the thread I linked above.
I have a Hemi swapped into mine and have next to nothing as for room.
I'll add to what Rick said - you also have to check the depth of the Spal fan you are considering. They vary greatly across the model line. In my case (also a Hemi) there is only one Spal model which is narrow enough and powerful enough. I run the 500 watt brushless.
Exactly what is a pwm I'm not the smartest when it comes to this stuff, but I kinda understand most of it
Ill have to look around I currently have a brushed fan I would like a brushless fan and something that pulls a little more air
Pulse-Width Modulated (PWM) Fan Controller

This one comes with a temperature sensor. It explains the benefits of a PWM also.
