Default engine overheating please help

i need help with a 94 integra ls manual transmission. the engine
overheats specially at high speeds. i already changed the water pump
and put in a new thermostat. my fans were not working so ran them
straight to my ignition, and as long as my car is on the fans will be
on. but the car overheats. usually theres steam coming out of the
reservoir and recently the engine got so hot tha the car turned off
before i could pull of to the side. any ideas or suggestions?

Does turning the heater on full cool the car down?

Check the rad for flow (is it EVENLY hot ALL over when the motor is fully
warm?)

Also check the rad fins for corrosion. They can corrode to dust in the
bottom middle portion.

Never let your car overheat or you will warp the aluminum head. I'm afraid
your engine now likely has severe damage. Did this problem happen all at
once or has it gradually been getting worse?

no the engine has gradually gotten to this stage. At first it would
only happen sometimes but now its only about 15-20 min before it
overheats

If the temperature rise is steady and relentless, I would strongly suspect
the radiator. Airflow would be a possibility except now you have the fans
going full time, and you report it worse at high speeds. I would hazard a
guess the radiator has had tap water added at least a few times (don't do
that) - if so, the minerals have collected in the radiator and have made it
nearly useless.

The radiator could be rodded out, but I recommend replacement. The radiator
is near the end of the life expectancy anyway because of the plastic tanks.
And in the future use only proper coolant and distilled (deionized) water.

Duckbill's concern about the head being warped should be checked by the
simple field screening test: with the engine cold, remove the radiator cap.
Start the engine, pinch off the hose to the coolant reservoir and place the
palm of your hand over the opening for the radiator cap. If you feel
pressure steadily rising against your palm within a couple of seconds or -
worse - pulsations, the head will have to come off for repair of the head
gasket or to be milled. A shop can do a chemical test to confirm the
problem. But I don't think that's likely. Head warpage comes from the head
not having coolant; the temperature soars. Assuming it has always had
coolant present even if the coolant is at the boiling point, you should be
okay.

Sounds to me like you need to check for the presence of carbon dioxide in
your cooling system. Either a blown headgasket or broken head bolt or both.
