i7 13700K at 100°C with AIO

[Handy Bag]

Hi everyone,
Asking for help even if I already know the answer. I've built a pc in the Cooler Master nr200p max case (with integrated AIO and power supply). I've built plenty of PC, but it's my 1st in mini-ITX format, and the 1st with AIO cooler, and maybe I'm doing something wrong.

When I boot the PC, it's all working well, but the CPU's temp goes through the roof in 5 minutes, up to 100°C, so I suspected an AIO issue. When I go to BIOS, the PUMP_FAN (the header where the pump is connected) shows 0 RPM. It's the same when I plug the pump on CPU_FAN or SYS_FAN. Of course I hear no sound coming from the pump while the PC is running. So I guess the pump is not working ? Maybe I've forgot to activate something or I don't know what.

Things I've already check/done :
- Change thermal paste twice
- Check if screws where to tightly screwed
- Check if I removed the plastic layer on the copper plate of the AIO
- Tested every fan pin on the mobo with another cooler

If you have any advice or idea on what is preventing the pump to run, I'll be happy to hear from you

Thank you

Here's the link of the whole case (the AIO isn't sold as a spare part I think) : https://www.coolermaster.com/fr/fr-fr/catalog/max/mini-itx/nr200p-max/

you never run the pump at 100%

Wrong, pumps are designed to run at 100% and should be run at 100%.

Would OP consider an air cooler by any chance? Noctua makes some pretty strong ones. I have a Noctua but not a very big one as my processor doesn't justify the expense. Still, it's efficient and effective.

considering its a mini-itx, im guessing OP cant, as it wont fit a big enough air cooler.

oops missed

my mistake, missed that essential nugget of info.

The cpu temp go to 100 in the bios screen?

Is the cpu under load in task manager? Minimum processor state get stuck at 100%?

13700k will pull ~ 245w at full load.

Set the PL1 and PL2 in the bios to a reasonable level vs basically being unlimited (4000w or something). Each mainboard calls these power limits different names so you'll have to google them.

Try a reasonable power limit within the coolers ability to cool.

please?
silicium can melt at a lot more degrees celsius than 100°C. isnt it good enough to cool a cpu with air? i never had aio...
can you tell me??
please.

Not true. The pump required 12 DC voltage supplying which makes no sense that running 100% will damage it.

@OP I avoid Cooler Master due to their poor quality. I had DC fans that is supposed to be quiet, but it is not.

Correct; this is why Motherboard makers started putting a labeled fan head for "PUMP"
This will only run DC mode and thus runs the pump @ 100% at all times like it's supposed to.

AIO Pumps were never designed to run dynamic RPMs. Think about it; why would I want the Liquid Flow to ever be slowed down? How does that make any sense. Cause if you put an AIO Pump on PWM, that's exactly what you are doing to it; which you never want to do.

You can manually control all Case and Rad Fans though; that is perfectly fine.

I went for this particular case because the AIO and the power supply were directly installed, so I didn't need to go for further investigation to find these two. But in the "regular case" (the one who's sold without the AIO and PS), you can easily go for the air cooling solutions.
I know Noctua has amazing products, as I use them in almost all PC's I had/made.

It goes 100°C in BIOS from a cold start after 5 minutes, same in HWMonitor. The CPU is behaving "normally" (appart from the temp part). I wanted to go do some undervolting to avoid crazy temps, but in this case, even that can't solve the problem imo.


CM finally responded my ticket, they are saying that they are going to send a spare part when they'll verify if the case is still under warranty (the invoice/the serial number when registered shows the manufacturing date...) I'll give some news when I get the spare part.

Thank you everyone for yours answers.

I do not recommend to try to go undervolt. It could stress the integrated circuit more than the normal operating voltages range. Plus, most motherboard BIOS doesn't allow go undervolting.

Hello, I just have received the AIO in spare parts from CM. Now it works perfectly fine : CPU is at 35°C in idle and a little bit of noise from the pump.
Over all the experience with CM support was ok, they're just responding after 50h. They sent the spare parts by UPS and it was very well protected.
Thanks to everyone that have tried to help me there.

[mtono]

oh yes!!!!

[𝗦𝗮𝗺𝘀𝗲𝗗𝗞 ✌]

If it runs 100c in idle it means you aint getting cooling at all. Remember the old school intel stock coolers? It would be the same temps! Install a program from your aio and check pump/fans curve and read speeds

My EK Nucleus 360 Lux AIO pump is 4-pin PWM and is plugged into the pump header.

Pump Speed Range: 3100 RPM ± 10%
Pump PWM Range: 20 - 100%

I had it set to PWM mode and run at 50% in BIOS for temperatures lower than 75C. Is this OK?
