It may!  I tried the 360 over the 280 with my i7 7820X in my secondary rig at one point.  Found that on average...temps ran a bit lower, around 7C less.  I overclocked the 7820x to 4.6 GHZ with a static voltage of 1.171.  the main object of the Skylake X was to keep voltage under 1.2 volts any way you can.  With the 280, which I still have, temps at full load run around 74C.  With the 360, I was seeing 70/71C.  It takes a bit longer for the temp peak to hit with the 360 vs the 280.  Fans run quieter on the 360.  With all that said...It is a toss up as to whether or not you will see an advantage.  I would start by adjusting the voltage on your CPU first.  Go to google or whatever search engine you find and see what others have found as far as the lowest voltage that your CPU will function at at the 4.8 GHZ.  Granted the 10920X is supposed to contain solder vs my 7820x having thermal paste as a conductor...but your temps seem a bit high.  Try a few things before you play with voltages...
Reapply your thermal paste between the pump and CPU...make sure it is snug and not to overtighten the pump back to the CPU...I use MX4...there are many good thermal pastes out there...
Play around with the voltages...don't let your motherboard set the voltage automatically...when I do on the X299 FTW K...my CPU will heat up like yours.  I read in a few threads...you should be about to reach 4.9 GHZ with around a 1.24 v setting.  At 4.8, you might try static voltage (start at 1.18 and keep going up).  Run Cinebench r20 or r23.  You will know when things are good, when either of the programs doesn't crash or freeze.  Lets start here and see where we can go.   Overall...your 280mm AIO should actually work with that CPU
 
I am currently running a 280mm AIO on my Ryzen 9 5950X and never see temps higher than 72C at full load.  I use a less aggressive fan curve on the Ryzen than I use on the Intel CPU.

Here's a decent video.  May not be the FTW-K but voltage may give you some ideas

Now with that said...remember that the chip I have on the X299 FTW-K is the i7 7820X...so it is going to be somewhat hotter than yours.  Here are some voltages I tried...
 
4.6 GHZ     1.171V
4.7 GHZ     1.18V  My cpu ran OK...but temps were uncomfortable for me around 92C
4.8 GHZ     1.21    Again...cpu ran...but temps were touching 100C
 
Mind you my chip has a TDP pf 140 Watts, where yours is 165W.  You have to play around with settings...and find where your CPU will give you the best performance with the lowest voltage.  Mine would probably have been OK at 4.7  but I don't like the 90C area.  Again...they used thermal paste on the Skylake X chip vs solder, which yours has...even the 10980X.  Again...download Cinebench r23 or r20.  Even use CPU-Z and under benchmark run STRESS test.  Have HwInfo open and watch your core clock and temps.  Example...if you try 4.7 GHZ at 1.18 and the CPU doesn't crash while running Cinebench....you can try lowering voltage to 1.175 and run again...if no crash...try voltage at 1.173 (may have already crashed at 1.175).  Now...once you get it to where you DON"T crash...ala 4.6 at 1.171 or 4.7 at 1.18, up it to 4.8 and add .005 increments until the CPU is again stable  Example...say you crash at 4.8 with voltage of 1.18...try voltage of 1.183 run Cinebench again.  If crash...take voltage to 1.185...keep upping in increments until stable.  Once there...check your temps.  Once you are at a place where your clocks are high enough...and stable enough with temps you are comfortable with...you are there.  Also in the bios, you don't need to disable C states...leave enabled. Here is the screen from my X299 FTW K
 
 

 
 This way the CPU can still thrust and do what is normal.  It will clock down and cool down when lower clocks or idle and thrust and stay at the top when used to max
