The advantage of that is you can expand on it at a later date. If you search you will see some of the things people have done with them.
Although I'm not sure what the performance is like compared to the H100. There is a thread on them from when they were first released though
What cooler do you run at the moment?
Honestly, good air is better than CLC. It is cheaper, cooler, quieter.. and has less that can go wrong.
Testing of Cryorig R1 Ultimate, NH-D15, PH-TC14PE ,Reserator Max Dual and H100i show air 6-9c cooler at 1-7dBA quieter when all are running below 40dBA. Running at full speed air is still 2-4c cooler but CLC are 25-38cBA louder.. that is 5-7 times as loud!! (every 10dBA increase doubles how loud it sounds to human ear)
About half way down the page.The loudness ratio 4 (four times the loudness) changes the sound loudness level by 20 dB.
The sound pressure ratio 4 (four times the pressure) changes the sound pressure level by 12.04 dB.
The sound power ratio 4 (four times the intensity) changes the sound power level by 6.02 dB.
The loudness ratio 3 (three times the loudness) changes the sound loudness level by 15.58 dB.
The sound pressure ratio 3 (three times the pressure) changes the sound pressure level by 9.54 dB.
The sound power ratio 3 (three times the intensity) changes the sound power level by 4.77 dB.
The loudness ratio 2 (two times (twice) the loudness) changes the sound loudness level by 10 dB.
The sound pressure ratio 2 (two times the pressure) changes the sound pressure level by 6.02 dB.
The sound power ratio 2 (two times the intensity) changes the sound power level by 3.01 dB.
