I made the mistake of not watching the video so i wasnt aware of the low pump output. i was just pointing out that air bubbles will cause a restriction in the system, thus causing low coolant flow.
No, not even close to the same system. A car's water pump puts out around 45psi with fluid reaching a temperature of over 200f. That's the pressure without the extremly hot coolant, the pressure is much higher at operating temp. Just the fact that you think a little electric pump that puts out 1-3 psi can compress air in a loop is laughable. Just because your PC has a water pump, rad and a block doesn't mean it has anything in common with a cars cooling system.
The only time air will cause a loss of flow is if there is a bubble in the pump, water will still flow through a block or radiator if there is air in half of it...air will not stop the water nor will the air compress by the intense 3psi of pressure.
The only thing they have in common is if there is water in the radiator, you lose cooling performance because there is no/little water in the radiator. Which is why you bleed out the air bubbles.
My GF is a mechanic and she thinks you're crazy to even compare the two....Edited by huhh - 7/15/13 at 4:33pm
