Watercooling heater-core pipe dimension question

[CheapGator]

If I have a pump with 1/2"in and 1/2" out, waterblock with 1/2"in and 1/2" out, Will a radiator with a 5/8 inch in/out be detrimental or beneficial or nada. This is kinda a physics problem, so have fun you engineers out there. Basically I'm thinkin if the water is in there longer the radiator will absorb more of the heat within the water because it will be there longer and it'll have better heat transfer. Of course I'm just makin that up off the top of my head but it sounds good.

If anyone has a thought on this if I'm wrong or right, or have personal experience with watercooling and having different inputs/outputs between the parts. I'd love to hear how it's working.TIA

bumpy, even if you don't have any factual basis i'd appreciate what you think about it

Well the size of the in/out being bigger prob makes no difference. Now if they were smaller then you would reduce flow from friction loss. Just like if you use a 90 degree elbow verses a 45 degree elbow. The 45 degree will give you much less restriction and help you keep your flow up. As far as the core is conserned, the larger the radiator the more capacity it will have to cool the water flowing thru it. Think of it like a car, you wouldnt want to cool you car with a radiator the size of a heater core.
