Question Cpu not cooling

[paxypaxyman]

So I recently decided to change my case (NZXT H9 Flow) and add an AIO (Cooler Master ML360L V2 white edition). I have a B660M - p d4 wifi motherboard and an aorus rtx 3080 with an i5 12400f. I put all my parts into my new case and plugged all the fans into a fan hub. I realised I didn't have an argb cable so my aio fans and aio itself doesn't have argb cables plugged in anywhere. I figured it would still work as it's just rgb but when I booted up my pc it went to desktop but was very laggy. I then checked my temps and it reached a minimum of 99C. I have thermal paste under the heatsink on the cpu and the aio is tight. I could also feel the water running inside the tubes. Thank you in advance

I think you must not do anything and destroy your pc

Did you remove the plastic from the bottom of the pump? It should've had paste pre-applied and a plastic cover over it.

Also, where did you plug the pump onto the mobo? Did you attach PSU power to pump? Is the pump working?

Yes the plastic is removed and I have a cpu fan header plugged in the mobo and the argb is not plugged in. All the fans are plugged in too with argb also unplugged. I'm not sure how to tell if my AIO is working or not

Despite saying you can feel the water running inside the tubes, you haven't said if you've plugged the pump into the appropriate header on the mobo.

Use a screwdriver pressed against the pump as a sounding rod and press the other end to your ear. Can you hear the pump running?

One tube entering the radiator should feel warm/hot. The other tube leaving the radiator should feel cooler if the pump is working properly.

If the pump is at the highest component in the loop, i.e. mounted above the top of the radiator, trapped air will accumulate inside the pump, reducing the amount of coolant moving round the loop.

If your CPU is reaching 99C, either the cooler plate is not making good contact with the CPU, or the pump isn't working normally.

Hang on a second here; the temperature delta between the liquid in the tubes should only be 1-2 degrees Celsius in most AIOs. Nobody's feeling that.

No.

In normal ops, the fluid gets to equilibrium all the way through.

On a previous system with an AIO, I had a temp probe on each of the 2 tubes, same distance from the pump and rad.
In normal ops, maybe a 0.0-0.2C difference.

Top mounted Cryorig A80.

Only under heavy load like Prime95 did it rise to maybe a 2C difference.

Under load:

Normal ops:

In fact if you can feel a noticeable difference between the tubes, most likely there is a clog.

Is the pump header not supposed to be in the cpu fan header? I put in both the cpu header and system fan header and both had the same results. Also, I did the screwdriver listening thing and I hear a whirring sound on both the pump and the tubes. I also hand felt both tubes and they both felt the same temperature and both of them had a slight vibration hopefully meaning that the coolant is running through. My pump does have one screw not screwed in on the top left which may have caused bad contact (I'm going to buy more screws) but when I physically press it down and boot up I still have the same cpu temps. Would not having argb plugged in affect hardware performance? Or is it only for aesthetics?

That is almost certainly the problem.

Just pushing on it does not work.

It shouldn't matter which header the pump is plugged in - as long as it's plugged, period.
No header has a default setting of 0, does it? The difference between AIO_PUMP/W_PUMP and the other headers is that the former's default is 100%.

Would not having argb plugged in affect hardware performance? Or is it only for aesthetics?

Yes and no. It is for aesthetics, but to implement those LEDs, performance and noise were sacrificed - albeit very slight.
If a model has both LED and non-LED versions, the LED version is weaker and louder - again, very slight.

Here is an image of my aio every screw is in tight except that one screw. Are you positive that is the problem?

"positive"? No.

Strongly indicative? Yes.

I had exactly the same with an air cooler...one screw was not quite all the way tight.
The CPU would rise to 99-100C, right from starting up.

It doesn't take much to be "not quite right".

Get that thing screwed down correctly and see what happens.

Thank you everyone for your help I got it working and it looks amazing. It turns out my fan hub wasn't working with the motherboard pwm cable so I used sata instead. I also bought a new mobo with argb. And when I found different screws to use for my AIO and when I screwed it down the temps were good.
