Alphacool RTX 4090 Core Reference Edition - KFA2/Galax - Reverse in and out water.

[AllanPSK]

I just received the Core model for my KFA2/Galax RTX 4090 SG and I would like to know if there is a loss of performance when inverting the water inlet and outlet in this block model.

The loop would look like this: Reservoir >> Pump >> Radiator 1 >> Water inlet through the OUT port of the RTX 4090 Core block.

The pump installed BEFORE the OUT port.

And guys, what is the reason, argument or logic in leaving the water outlet on the right side?

Thanks in advance for your attention.

If you go in at OUT, the jetplate will not work and you will lose a lot of cooling capacity. This is not a cheap continuous cooler like they made 10-15 years ago, it didn't matter then, but the cooling capacity was also modest compared to the waste heat of the cards at that time.

The logic behind this design? If we did it the other way round, someone would complain. What would be the logic of doing it the other way round, except that it would be better for your system?
