My new build plan has a hybrid 1080 with a 120mm radiator and I am also going for a 240mm H100 AIO cooler for the CPU mainly because these units weren't a thing last time I built a system.

Which of the following setups sounds least wrong?

Option 1

1. GPU Cooler on the back of the case drawing in from outside.
2. CPU Cooler on the front of the case drawing in from outside.
3. Two 120mm exhaust fans on the top of the case.

Both Rads are getting cold air, but the GPU rad is blowing hot air onto the CPU waterblock.

or Option 2

1. CPU Cooler on the front drawing in from outside.
2. One 120mm on the back drawing in from outside.
3. One 120mm fan and the GPU radiator on the top pushing air out of the case.

The GPU rad gets fed "hot" system air but since its the hottest part of the build the air its getting can't be that hot can it?

Any advice would be gratefully received.
