Question Input on my cooling

[blobdagr8]

So I'm looking to switch things up a bit in my system. I recently got a liquid cooler for my CPU and have been vastly underwhelmed, to say the least. I have a case which allows me to have 3x140 fans in front, 1x140 fan in back and 2x 140 fans or 3x120 fans on top. Currently my 360 radiator is on top pushing the air out. The fans in front pull air in and the back fan goes out. I'm going to be getting a 120 radiator for my GPU soon and I'm wondering what would be the best setup for optimal air flow to keep everything nice and chilly? I was thinking of putting the GPU radiator on the front, pulling in with the other 2 and keeping the top and rear fans as exhaust. I'm unsure as to whether or not radiators should always pull air in or what? Maybe since I have it as exhaust currently that would explain why it doesn't keep my CPU as chilled as advertised? I have the Thermaltake water 3.0. That'd be the most efficient setup, right?
I have a 1080ti and 7700k. Both seem to run hotter than other products in their lines. But my GPU runs ridiculously hot, I'm talking rockets up to 80 on fallout 4, and my CPU, with the 360 radiator, goes around 40-60 under medium to heavy loads. Maybe the pump isn't working right? Or idk really, I'm new to liquid cooling.

Liquid cooling is really air cooling.
It differs only in where the radiator heat exchange takes place.

As you have noted, a radiator on top will use warmer air generated by the motherboard and gpu to do the cooling.
If you were to mount the radiator as intake in the front, your cpu cooling would be better at the expense of higher motherboard and gpu temperatures.

If your cooler is installed well, you should be seeing 10-15c. over ambient.

Do not be alarmed by 80c. on your graphics card.
Such cards do run hot, but they are built to tolerate heat.
They increase performance until they reach that 80c. target.

If your cpu is in the 75-85c. range under load, that is ok.
The processor will throttle or shut down to protect itself if it senses a dangerous temperature.
That is around 100c.

Me... I would simply use a noctua NH-D15s air cooler and be done with it.
Not a popular opinion on these forums.

1080Ti is a 250watt TDP part.

A single 120mm radiator AIO isn't going to cool it very well if you run long gaming sessions. It will just continue to dump heat into the coolant while the single fan tries to keep up. Most 120mm radiators are good for about 130-150watts to stay within a 10-12 degree Celsius delta-T.

What AIO is being used for the CPU? You mentioned it's a 360.

Just 'having liquid cooling' doesn't mean it is 'good liquid cooling'.
