I noticed two fans, driver side fan blows air from front of car towards rear, into the engine block (which is what I would think all fans should work) passenger side fan, however, goes the OTHER way... from engine OUT. While not all vent fans can reverse their blade direction, certain fans that use alternating current (AC) motors can, such as a 110-volt AC motor and certain shaded pole motors. That is your Reverse direction. When the temperature exceeds a specific value -- usually 215 degrees Fahrenheit -- the computer will turn the fan … I replaced the ccrm and the fan connector.

Eg., if you have a fan on the back of your case exhausting air, and you are mounting the radiator in the front, you want them blowing in into the case (pull configuration). There are many applications where the radiator is in the back of the bus or car in a place where the engine gets no direct benefit from air blowing on it. I've been having overheating issues.

The Corsair H110i instructions say to set the two radiator fans on intake (sucking outside air thru the radiator) and frankly, I think I agree and would rather have cool outside air coming in thru the radiator vents. 3: Example of a uni-directional fan, with straight blades. 1: Example of a bi-directional fan. If a vent fan is rotating the wrong way, it may be fixable. The "fan" is usually a cylinder with curved ridges designed to push air laterally towards the ducting and not actual fan blades like in a ceiling fan that would push the air vertically. 1st thing you should do regardless of your gpu cooling solution is mount the cpu radiator to the top. 99 eclipse GS NT auto trans. The fan has two wires going to it; Black and Black with a Blue stripe. The Intake-exhaust direction should go front-to-back and bottom-to-top. Your cooling fan operates through a series of circuits. I just want to compare blowing versus sucking in my system. Fig. Step 2: Now switch the fan to go the other direction. Fitting a fan the wrong way round does not cause it to 'suck' air in the opposite direction, just means it … Fig. One would have to monitor for a time to make sure that the temperature still stayed within the safe zone of course.

Still didn't work so I just wired it to a switch temporarily. However, the radiator fan does not always start spinning on ignition. I was told that Gold Wings already do this below 20 MPH. direction from that shown here will result in an increase in the fan’s power consumption, fan noise and also the air volume it moves. The fan should blow air toward the engine (i.e., same direction as the air flow when the vehicle is in motion). forcing it to change direction suddenly, like entering a radiator, disrupts the flow pattern, slows it down. You will also be able to identify the Exhaust side as you will see power wires entering the fan motor.
