redoing water-cooling, loop is rad-cpu-pump, right?

post #1 of 4
Thread Starter 
I'm putting the water-cooling in a new system since my last water-cooling system from 2001 won ugliest machine last July

just making sure it's radiator-cpu-pump/reservoir, then back to radiator, right? Since I want the coldest possible water going to the cpu the water should hit the radiator right before the cpu I'm guessing.

that's how I had it... wow, 10 years ago? Damn.... well, anyway, so I guess that's how I'll do it again.

Loop order does not make a difference. Just make sure that your reservoir comes before your pump/is above it.

Water temps are going to equalize, so it doesn't matter what order you have your parts in.

Pretty much what kinru said is right after about an Hr the water comes to an equilibrium temp based on rad, fans, and ambient room temperature. You can only go so far with hardware before you hit the diminishing returns mark and then lowering ambient temps is the only way to really improve loop temps. As long your pump is sucking water and not air your loop will be fine.

The water in your loop only changes by about 0.5C as it goes around, so the warmest water in the loop is only about 0.5C warmer than the coolest.

Besides, in a single block loop there is nothing to the heat the water other than the CPU, so loop order literally has a 0C difference.
