Hi

 

I was wondering- how come is it possible to have two tubes in parallel between the GPUs? I can't seem to figure out the waterflow...

 

Picture as example:

 

phanteks_enthoo_primo_full_tower_case_re

 

Nevermind my question, found the answer.

 

Edit: Answer- parallel vs series loops for GPU.

What was the answer?

 

Water gets in on bottom left, splits up, runs in parallel through both GPU blocks, converges again and gets out on top right (or the other way round, can't tell from the picture)

So they have hot water running from the GPU's to the CPU?

 

 

That just doesn't seem smart.

Actually that's a common misconception. The temperatures in a loop vary only minimally from the hottest to the coldest point (like really barely worth mentioning at all). The water runs so fast through the loop, it doesn't really heat up much in the blocks - that's why loop order doesn't really matter (except for res->pump).

I'd like to see a test of several pumps, testing for longevity, looking to see if it matters whether or not you have the rad before the res and pump. As opposed to after the the pump. To see what effect a "hotter" pump might have on the longevity of the pump

I don't think there'll be any difference, since temp differences are so minimal.

Dude, you have 7k posts and you don't know that the order of the loop does not matter?.. Wut.. I will be running a different config that will definitely cook my GPU's and CPU. My plan:

I will definitely post pictures of melted components just for you.

I was pointing out that you would want temps as cool as possible for the liquid flowing into the pump, so the pump can run as cool as possible. electrical motors (such as the ones in pumps) tend to degrade a bit faster with higher temperatures.

 

I was wondering if having the radiator after the CPU and GPU water-blocks might effect how long the life of the pump is. I've never seen this kind of test done, and wonder if it might make a significant difference or not.

You still sound as if the water would be something like 20°C or so warmer after the blocks than it would be after the rad. It's more likely in the region of 2°C difference, rather than 20°C. That's why loop order does not matter. Seriously.

If a test on longevity hasn't been done, you can't conclusively say that there is or is not and effect.

 

Again, it's this little thing called curiosity, ever heard of it?
