5600x should be really easy to cool, if you don't plan on upgrading to higher core count CPU for that same socket I would suggest taking easier route of getting decent air cooler. Depending on space in the case you could also get some AIO, I don't recommend anything specific because that CPU really doesn't need that much cooling.

As for GPU I am not sure if there are AIOs for 3080 Ti, I assume yes. And I also assume you don't want to do full water loop for both GPU and CPU.

Something like NZXT Kraken should be a thing for 3000 series. Slapping AIO on GPU and decent air cooler on the CPU is what I would do in this situation, if there is enough space in the case you can slap AIOs on both.

 

You could get the below AIO for the GPU and add any CPU block to it. I have the alphacool block on my 3090FTW in a loop and the core/memory dont go over 50c gaming. I also had a cheap alphacool XPX block on my 12900k, and it worked just as well as my expensive velocity2 CPU block...

Alphacool Eiswolf 2 AIO - 360mm RTX 3080/3090 FTW3 with Backplate

The Alphacool Eiswolf 2 is the first full cover GPU AIO waterblock from Alphacool. It is based on the Alphacool GPX Eisblock Aurora GPX water block, a pump unit and a 360mm NexXxoS ST30 full copper radiator. The latter is equipped with...

Alphacool indeed makes some nice stuff. Didn't realize they had 3000 series water blocks with AIOs. With fast connect thingies as well.

 

I don't quite understand how to add a CPU block, such as to said configuration, but I will figure it out!

I actually did acquire that one air cooler on here that was a deal (Amazon.com: Pccooler GI-R66U, Premium CPU Cooler with 6 Copper Direct Contact Heat Pipes, 240W TDP CPU Air Cooler with Slient CPU PWM Fan 120mm for AMD Ryzen/Intel LGA1151 115X : Electronics ), I may just use it instead if it's sufficient. My CPU has overheated a few times and the PC shuts down.

 

As potatovonepic stated, there really isn't a need to add a cpu block to the 5600X, I believe its only a 65w processor. I just mentioned that AIO above as its a good GPU block and expandable to include a cpu block. TBH, if you just want to cool the 3080ti, I would just get one of the hybrid kits from EVGA if available. I had one in the past and it cooled the gpu core really good, except for the vram on the back side obviously. But you don't have to worry about that with the 3080ti. The only problem is that they don't appear to be in stock...
