First, replace that 165 degree thermostat with the factory specified 195 degree thermostat which is required to keep the computer's programming happy. As you can see, it didn't reduce your engine temp in your warm climate conditions anyway.
One more thing, that Griffin electric fan is not capable of pulling as much air through that fan as the engine driven fan can. Electric fans are rarely the right choice when you have a cooling issue.
Not to mention that 210/220 is pretty normal for the Jeep in pretty much all conditions. It shouldn't run below 210, that temp is where the TJ's engine was programmed & designed to be most efficient.
