that fan is for your a/c system it shouldnt be affecting your cooling system. when you put the thermostat, did you put the bleed hole facing upward?.

If you installed an aftermarket thermostat like a Stant, then there's a good chance that you'll have overheating problems. Install a new OEM unit.

You may also have air in the cooling system. Do an air purge.

that fan is not intended for what you think. its an auxiliary fan that comes on when the a/c is on. i think you dont understand how fans work in the first place. theyre not needed for driving under 20-30 mph. that goes for your primary fan as well. theyre only for when the car lacks sufficient air flow to jam air thru the radiator. you have an 89. barring a bad water pump, you need to look into the radiator being plugged and/or fan clutch being bad.
