GPU first in the loop or CPU?

Just piping up my loop now in my new Fractal Design Node 804 ( Amazing case by the way )

Now the neatest looking route for the pipe work would be having my 290 cooled before my 3770k but I'm worried about the temps on my 3770k as the 290 is a hot running card and surely will affect the running temperatures of my 3770k?

I can put the 3770k first it's just a bit of extra work and a slightly longer run of pipe.

So would the 3770k be ok being cooled after the 290?

Loop order doesn't matter long as res then pump.

What he says.

So loop will be:

Pump > 290 > 3770k > 240mm XSPC rad > Thermochill 120mm rad > reservoir > pump

Looks like I'm good to go then..

I went Res/pump combo > 4790k > 360mm XSPC rad > GTX 780 > 240mm rad

That way the water is passing through a rad before it goes to the CPU or GPU, I don't know if it makes a difference but it sounds like it should.

That's what I'm going to do Matt, I have a second 240mm rad on the way to go between the CPU and GPU.

As the others have said loop order doesn't matter, I'd be surprised to see a 1 degree difference between the warmest and coolest point in a loop

So should I go

240mm Thermochil rad > 240mm XSPC rad > CPU > GPU > Res > Pump?

Or

Pump > GPU > 240mm XSPC rad > CPU > 240mm Thermochil rad > res > Pump?

It will make no difference to the performance. Choose your loop order on which gives you the shortest run of hose, with the least bends.

Providing the flow rate is sufficient, the loop order won't noticeably affect performance. It does make a difference to the aesthetics however. I chose the simplest route with the least tubing.
