It seems really good, so maybe I am doing something wrong.
Update - (last 3 pics added) - I Frankensteined my PC case and move the radiator to the front of my case. I believe that has dropped the CPU temperature by 4 degrees on average. I moved the radiator in support of my new Aorus X570 Pro WIFI, but I think I would have had room for it after all. But, I am glad I move the radiator.---------------------------------------------------------------------------------------------------------------(I hope you can see the pictures ok)I have added some before and after pictures.

I have my system cranked up pretty high, so it is pretty noisy. I run the pump 100% of the time. I cant think of any good reason not to run the pump (I have run the pumps in my aquariums for 15 years straight without an issue and I dont see much difference).I dont have the best looking system by far, but I am proud of it. My AIO is a major reason for my pride.I hope this information helps.

5.0 out of 5 stars great budget aio, the fans suck tho
Reviewed in the United States on June 30, 2021
big upgrade from hyper master 212 that was in there before,
allows me to overclock my i7 9700k to 5.1ghz, great temps either idle or under load. the highest ive seen it was 75c

however the fans really suck, due to my case i wasn't going to be using them on the radiator because then the rgb wouldnt be visible so i just used cheap 1200rpm cooler master fans, have since ordered noctuas. i decided to mount one of the fans as exhaust in my case and i had a rattling noise. i really thought it was the pump for a while but removed the rgb fans and my case is now whisper quit and cold

UPDATE: so it seems like the noise was the aio, so what i did was set the aio as acurve like you do with fans and now my system is very very quiet, even at idle. before there was a faint hum at idle and i thought it was my psu fan. now it's set to around 1200 rpm at idle instead of 2200 and it ramps up when my cpu gets hot. now i can't hear it at all under load because of the fans
