CPU suddenly overheating

[_Under2World_]

So, around two weeks ago, my PC turn off himself while gaming and reboot into the BIOS. It was the first time so I just left the BIOS and just after that I noticed my CPU temp being way higher than before. I'm reaching almost 80°c IDLE, and well 100 with thermal throttling in game. To be clear, it wasn't the case before, the temp were about 42° IDLE and 75° while playing. It's the first computer I've totally build myself back in June and perform well without temp issue for month, I did change the thermal paste last week just in case (without that much hope) and nothings have change. I have every driver updated and except a BIOS update I don't have any idea about what I could do.

I've done no overclock except on the GPU. 

I'm accepting any advice since I'm pretty new here.

 

PC spec:

CPU : I7-11700K, (actually downclocked to avoid shutting down)

2x8GB ram, 4000Mhz G.Skill ripjaw V 1.4v

Motherboard: MSI MAG Z590 Tomahawk wifi

cooler: MSI coreliquid 240R

GPU: RTX 3070 Aorus master (+175Mhz core, +1000Mhz VRAM)

 

here a screen while doing nothing, same temp as IDLE than before while playing.

It sounds like the pump (or something) inside the MSI CoreLiquid 240R AIO has either failed or is beginning to fail.

Can you feel any vibrations with your hands, or hear any hums coming from the CPU block/pump?

If you hear nothing, or feel nothing, the pump has probably died.

The MSI center say that the pump speed is 4,000 RPM (always has been), since the pump is inside the radiator block I can't tell without totally stopping the fan if I hear noise from it or vibration.

 

I did and I can hear a noise coming from it.

Pump RPM doesn't matter if it's getting low on coolant, has a blockage or something else going on.

First thing to do:
If there is a way to check the coolant level and top it off, that's what you'd need to check and do if it is low.

BTW how old is your AIO unit?
I'm not familiar with AIO's by model (I always do custom watercooling here) and so on so if it's a new unit I'd also be ready to possibly do an RMA of the unit.
If it's over 3 years old I can see a coolant level issue being a possibility here but don't rule out the rest that's been mentioned above either.

I built my PC in june with only new part. I don't know if there is a way to look at the liquid level or even replenish it if needed, I'll look for it.

I guess I can make work the warranty if the issue come from it

I agree that this sounds like a dead AIO.

Ah yes, the pump it in the radiator for this AIO design.

Where is your AIO mounted in your PC? Top? Front? Bottom?

 

An air bubble/pocket *might* be lodged into the pump.

IF that is the case (and the pump is not dead), you can try tilting the PC side-to-side, forward-and-back, to dislodge/move the air bubble/pocket out of the pump.

Instead of moving/tilting the ENTIRE PC, unscrew the radiator, and tilt/move that around -- with the PC turned OFF.

 

If that doesn't fix the issue, you may need to start an RMA with the retailer/MSi, or get a brand-new replacement AIO or something.

I believe that the purpose of placing the pump in the waterblock was to avoid bubles to get stuck in the pump, if that's the problem that would be dumb xD.

thanks for the tips I will try this asap and contact the support if it doesn't work!

Ehhh...not according to MSi's marketing bit

RADIATOR PUMP DESIGN

The pump has been integrated into the radiator for sound dampening and noise reduction. Additionally, placing the pump into the radiator also increases the pump's life expectancy by moving it away from the heat source.

 

If you radiator is mounted at the top of the case, there is a HIGHER chance the air bubble is get lodged inside the pump.

Air bubbles / pockets will reside at the highest point.

What I'm trying to explain...since air weighs less than liquid/water.

Thanks for all the help, I tried to turn the waterblock in multiple angle in case it was an air buble, the problem's still here but everything had time to cooldown and I noticed that only the air coming from the top right corner of the watercooling was hot. The liquid is definitely not moving inside and I will now contact the support.

Thanks again for the help everyone!
