Is my AIO pump faulty?

I have two computers with Corsair H60 AIOs. According to the ASUS monitoring program the pump speed never changes. However, the AIO fan speed increases as the CPU temperature increases. This behavior can be varied some by modifying the fan curves.

How is this relevant?

whatever it may be, there is little to nothing one can do to fix such AIO issues, besides changing a rusty fan if it was the case. Checking or swapping headers, some software tricks if it has one, maybe detach it and give it a shake about, wiggle the liquid & bubbles in it while breathing in some hopium gas. Otherwise RMA warranty or check with the producer.
Quite complicated enclosed system with moving parts, only fans are serviceable. Noise may be one thing as long as cooling is unaffected, but once that gets hit then its obvious something gave in. Most times its the propelar getting damaged or sludged in.
On air not much can happen but fan dying and cause is pretty obvious.

So can't I just RMA it and get a brand new one, same model?

?? Whats this when its at home?

Does not hurt to try.

The OP said his pump speed increases. The speed should be constant. If it is really changing then it is faulty.

Here, same phenomenon I speak of, I've been experiencing it to this day

RTX 4090 PUMP NOISE.mp4

I downloaded the file (300MB+) and listened.

Sorry, but I didn't hear anything that seemed obviously different from fan noise. Maybe someone else would have more critical hearing.

The speed is controlled by the motherboard, unless he has it plugged into a special pump header.

One of the complaints about my main motherboard is that it doesn't have a pump header. All of the headers can be used for either fans or a pump, and have variable voltages by default. The board has a long initial setup period (probably not the correct term) for DDR5. Having the pump essentially not running for that time causes the CPU's thermal shutdown to trip. (Solution: plug the pump into the optional CPU fan header. After the RAM is recognized and I can get into the BIOS settings, set that header to full on.)

Unfortunately this all depends on how the specific pump is connected.

I am pretty sure that pump is PWM and that it's rpm will vary depending on CPU or some other temperature setup in the pumps profile. Even if it is not a PWM and pump speed can be controlled by varying the the voltage. It doesn't need to run full speed, though most people setup the pump to run at a fixed speed.

EDIT: I just watched the OP video - I couldn't before because I was watching a movie. THE OP SYS_FAN_$_PUMP I assume is the actual pump, which is PWM from the video, and he is gradually increasing the pump speed to illustrate the issue. It is quite loud. Even at 100% it should be pretty quiet even if you open the case and put your ear nearby.

Really? Show me where you said that?

Is my AIO pump faulty?

Problem is that when my CPU hits 80C, my AIO pump speed (not the AIO fans I guess) increases very substantially and that gives these very loud noises, it's a very specific kinda sound Is this normal or not? I thought AIO pumps are NOT supposed to be very loud even at 100%, meanwhile my AIO pump...

You sure? It's so clear to me. 2:12 mark, this is VERY important, that 1 second you can just hear it.

this is what I'm saying too. Yet the shop keeps being a j%rk. I will not let them deny it. At least for the dysfunctional broken InfinityMirror alone

**7900x, Deepcool LT720, stock AIO fans,** also the Infinity Mirror doesn't have LED on it which apparently it SHOULD

I'm guessing in all the time you have had this computer you not once checked the manual for the AIO,

https://www.deepcool.com/download/pdf/LT520&LT720.pdf

and that there is an RGB cable from the AIO that needs to be connected to the appropriate RGB header on the motherboard,

Also the pump is not PWM as it only has a three wire connection. One more thing that most others posting here have said, stop running the pump at variable speeds as they are designed to run at a fixed speed.

It!'s unbearably loud at past 50%

I tried a couple of times, with particular attention to 2:12.

Nope.

The clacking of the keys is quite loud, though.

I hadn't noticed that the pump is 3 wire (not PWM), but that's pretty clear.

Then you should be contacting Deepcool for a warranty replacement. According to the specs,

LT720 - DeepCool

The DeepCool LT720 high-performance liquid CPU cooler provides strong heat dissipation power with a 360mm radiator, three precision-tuned FK120 fans, and a multidimensional infinity mirror top cap. - DeepCool was founded with the mission of providing professional, innovative, high-performance PC...

the pump is rated to run at 3100 RPM (+/- 10%) and 19 dB, which is quiet enough that you would have to all but put your ear on the pump to hear it.

Thank you I'll use that as a proof when having it RMA'd via the PC shop because they won't listen
