Should I switch to liquid cooling?

[MagicalDuck]

I have a R7 2700X CPU, and I've been using stock cooler for the past few months, paired with MSI GTX 1060. The CPU on max load never hit 80C, the maximum I saw it was on 78C. But, I recently switched to MSI RTX 2080 Ti, the GPU on max load reaches about 75C, but the back plate of it seems to get way hotter than that, heating up the CPU and RAM. I have 5 case fans, 2 blowing in from the front, 1 blowing out to the back, and 2 blowing out from the top. Yet still, the CPU while gaming gradually keeps getting hotter and hotter, about 1C every 5 minutes. I've already been at the point, where the CPU reached it's maximum temperature and simply shut down my PC.

A friend of mine uses Corsair H115i RGB PLATINUM liquid cooler with the same CPU, and the same GPU. And for him, it does not go over 65C, ever. But I am not so sure about liquid coolers, never had one, and I've heard that a lot of them fail or leak, ruining other components. Not sure if I should take this risk. So, does anyone know any possible air coolers for this issue, that would look just as nice as the stock one, or even better - and do the job better? Or maybe can suggest a liquid cooler?

My case is - Phanteks Eclipse P400S

Picture below, of how it currently is looking (And the glass is dirty, because I keep taking the glass panel off, so that more air could come in and CPU not reach 95C)

I wouldn't do that if I were you. Think about what happens if your AIO starts leaking and kills your expensive GPU.

This might be costing you about 2-3°C. The front fan on top is drawing fresh air out of your case before it gets to your CPU cooler.

 

In terms of air vs water, a big air cooler like a NH-D15 or Dark Rock Pro 4 performs identically to a 280mm AIO.

The backplate can't be hotter. Keep in mind that it doesn't take very high component temps for them to be too hot to touch. 

What's more likely is that the case airflow isn't keeping up with the increased heat from the more power hungry graphics card very well. 

As mentioned, the top exhaust fan is just removing fresh air before it gets to the system components. Remove at least the top fan closer to the front or flip them to intake.

Can you put another fan at the front for more air intake ? like move one of the top fans to the front for more air intake. Having three fans that takes air out wont help much if you don't supply it with enough fresh air, it might even introduce more dust into your system since you are taking more air out of it than you supply it meaning that it tries to take more air through little spaces that might not have a dust filter on them.

You don't really need a new CPU cooler the box cooler should be good enough except u have something like a high overclock applied.

The RTX 2080ti cards produce a lot of heat and it gets distributed into your system heating up the air inside over time more and more that is what makes the difference from before when you had the 1060.
