Noisy AIO Pump

Last night the AIO pump suddenly started to make noise that it didn't do before. Not overly loud but definitely hear it pumping which I didn't hear before.

Everything seemed to be running OK since I was just watching YouTube videos when the noise started. I then decided to run a CPU benchmark and see if my CPU temp was going to go crazy high.

I ran Cinebench R23 Multicore for about 10 minutes which caused 100% CPU utilization on all cores and the temperature never went over 64C. As soon as the benchmark was over it went immediately back to the idling temperature of 36C.

The AIO pump speed is running at about 2200 RPM and all other stats seem good and the system seems to be running like normal other than the louder than normal sound in the AIO pump that developed last night that won't go away. It had been very quiet since I got it a few months ago.

The Cinebench score was 20,821 compared to the 20,782 supposed identical system.

I had taken the side cover off to verify which item was making the noise. I also notice that if I push slightly on the AIO pump that it changes the sound ever so slightly.

I wonder if anybody else has had this experience. I would really hate to have to send the system back or figure out how to do the surgery to change the AIO out myself.

I am hoping the noise diminishes or I get used to it since it is annoying. I hate to think that this is the sign the AIO is getting ready to die and ruin my good times I have been having with the new computer.

I have the Velox-X case so the case was cold to the touch even during the Cinebench benchmark. My system case never seems to get warm unless I am pushing the 3080 in GPU intensive games on Ultra and then any heat is exhausted very effectively.

Oh well, maybe I will say a little prayer and the AIO pump will get healed and this all can be marked up to a bad AIO pump day.

Ugh. I'm new to them too, but mine is 4yo and fine. I'd find a local place to fix it before I'd ever send it anywhere if I didn't think I could handle it. You could take the opportunity to go Noctua....

Very cool that worked.. I haven't tested it as exhaustively as you have, but just my casual observation hasn't shown the 100% > 80% drop made any noticeable change to proc temps. I can't remember what mine was before (probably 2200 or so based on the 20% reduction), but now it runs around 1880-1900 and is completely silent. Your temps are better than mine...my idle temp is around 45C or so (5950X in a Lumos).

hoserator,

My AIO configuration came preset to 100%. I'm under the impression a lot of AIOs come set up that way by the builders. I know I am glad that the racket went away when I reduced it to 80% and the temperatures are as good as they were at 100%.

The noise was hard to describe. It wasn't bubbly or anything. It was just an extremely rapid putt putt sound that didn't change. It wasn't that loud but I knew there was something wrong.

I am so thankful for the Digital Storm Forum and its members! I was helped when I was trying to configure my new system a few months ago and the help with the AIO issue today was a big deal to me and put a big smile on my face.

Digital Storm Forum has the absolutely best members!!!!!!!!!

Happy for you, Ken!   

Originally posted by hoserator I have the pc lights set on temp and that way I keep track. Great visual. (also have HWMonitor and Corsair Link on in a second monitor for details).

I setup a stat screen running AIDA64 so I can just glance over at the case for temps, fan speeds, etc. My first screen (cheap Raspberry PI monitor from Amazon) died after only a month or two, but the current one seems to be holding up ok. I tried playing God of War on it the other day which was kind of fun for about 30 seconds. I dunno why so many people game on phones...the screen size kills it for me.
