Do I have my custom loop setup correctly?

[heaterfullof7980XEs]

Would the orientation of my rads and pump affect performance? I am getting around 80C when running benchmarks on my new build with an ultra 7 265kf. I am running it stock right now and am using 2x 360 radiators. Is this normal temperature for arrow lake?

Is that radiator against a wall? If so the heat might not be able to escape properly, thus increasing your temps. But the setup looks fine overall, as long as the pump is not the highest point in the loop

If it's pumping to the CPU and then the rad then that's good.

The other way around means the pump is pumping warmer water which is generally not a good idea.

 

Do you have a reservoir?

They help a lot for capturing air, filling system, and the extra water volume helps stabilize temps.

It goes pump ——> Block ——> Top Radiator ——-> Bottom Radiator ——-> pump the pump comes with a reservoir but there’s no big external one

Yes there is some space behind the radiator it is not literally hitting the wall, I guess it isn’t optimal, but bad enough to cause 80C temp at 190w? Doesn’t perform as expected.

Could try holding the loop further away from the wall temporarily and see if temperatures drop, although I'm not sure how much difference more breathing room would make, as you have highlighted

Is the pump the highest point of the loop, or is there a radiator or reservoir?

Loop order doesn't *really* matter. Flow rate is far more important. The temp delta between the in and out ports on your water blocks is only a few degC
The theoretical ideal loop order is reservoir-pump-cpu-gpu-radiator(s)-reservoir, but ultimately it shouldn't matter
There are several parts to this. First, you want the water in the res to be cooled so you minimize the heat your pump is exposed to. Then you want your pump to be directly fed from the res to maximize the ease of drawing new water in. Then you want to cool the CPU first because it's almost always going to be colder than the GPU (at least while under load). Then the GPU can dump as much heat as it can into the slightly warmed water. 

 

There are two things that are WAY more important than loop order:

1. Pump has to be below highest point in the loop to prevent aspirating air
2. Keep the pump at a constant speed. Usual rec is 80%. while the pump can change the speed, it incurs more wear and tear.
