CPU running Extremely hot

[Prof_Cookie50]

Hi,

My CPU is running at 100°c, i reached out to the company I brought it from and they suggested that as it was 2.5yrs old that maybe the AIO pump had given up and that was most likely causing the temperature increase as I had had no issues at all on the 2.5yrs and then all of a sudden this.

So I replace the AIO cooler, and still no better, any advice would be appreciated. This is my first computer and I don't know where to go from here.

This is the pc specs:
Processor (CPU)
Intel® Core™ i7 Eight Core Processor i7-11700 (2.5GHz) 16MB Cache
Motherboard
GIGABYTE B560M DS3H (rev. 1.0) : LGA1200, DDR4, USB 3.2
Memory (RAM)
16GB Corsair VENGEANCE DDR4 3200MHz (2 x 8GB)
Graphics Card
8GB NVIDIA GEFORCE RTX 2060 SUPER - HDMI, DP - VR Ready!
1st M.2 SSD Drive
1TB CORSAIR MP400 NVMe PCIe M.2 SSD (up to 3480 MB/R, 1880 MB/W)
Power Supply

AIO Cooler Corsair H60x elite 120mm

Yeah the clear protector was removed as it was a hard plastic cover, there is a link to the pc internals as I can't work out how to add pictures to this, sorry first time here.

@Prof_Cookie50 all looks okay to me.
does the radiator get hot when the cpu is at 100c?

The radiator doesn't get hot but the block over the CPU gets warm.
Here is the HW monitor screenshot. Of it being idle.

When is the CPU hitting 100c?

What are you using to monitor it?

If the CPU is permanently 100c then the only reasonable conclusion unless you have some crypto virus mining with your CPU is that your cooler mount is wrongly fitted/broken and not making contact with the CPU properly.

CPU is hitting 100 idle, and I'm using HW monitor to monitor it.

I believe the cooler to be mounted correctly and making sufficient contact with the CPU.

If it hits 100 when idle the cooler mount is pretty much always the issue, assuming your cooler is functional and the pump/fans are working.

The only other point of failure is the IHS making contact with the die and I'm pretty sure these are soldered.

The pump should be working correctly and I can see the fans are running.


I am not sure what the IHS making contact with the die is.

When installing the new cooler I followed the instructions and used the correct spacers etc. for the CPU bracket I have.

definitely idle in task manager? (sorry not teaching you to suck eggs, just making sure_


is the radiator exhausting warm air or cold air?


looks to be proper throttled. vcore 0.6v eeeek

Tbh, you are far more an expert on this than me so I would rather cover everything basic just to make sure.

The air out the exhaust is cold air.

No idea what the vcore is

 

[Prof_Cookie50]

I was about to suggest this. It seems that one sensor has failed. The question now, is that reading causing any throttling? affecting performance? or affecting the cooling fan speeds? If not, they you can ignore it.

The only other thing I can think of is a failed sensor, but I've only seen that once (it was ages ago) and in hwmonitor the cores are reading different values which suggests it isn't just the one sensor reading 100c.

How would I be able to test this to see? And I could manually set the BIOS to put all fans on max to see if the CPU still clocks 100°c

your tmpin values make me think it is not a cpu load issue (ie the CPU voltage regulators are not loaded hence why the mobo is cool)
which only leaves a bad cooler mount, a failed pump/fan header
as tetras says, the IHS is soldered on, so unlikely to be the cause (an uncontrolled solder spliting would've damaged the cores)

Should I see about a replacement cooler to double check it didn't get delivered dead on arrival? Or is there a way to tell?

 

[Prof_Cookie50]

Have to ask the stupid question after looking at your fan rpm, have you plugged the pump into a fan header?

How would I know this, I unplugged the old AIO pump and then plugged the new one in where the old one was.

 

[Prof_Cookie50]

did you buy your computer new? and where from?
should it not have had a 3 year warranty? (not sure where you buy it from - ocuk has a 3 year warranty)

Yeah brought new from pc specialist in nov-21, 3 year labour warranty and then various parts warranty depending on the parts/manufacturer warranty. But this cooler is band new only arrived today from Corsair. So has 5 years on it.

I'm going to unwire the AIO and then wire it back up just to see, I will try anything at this point.

 

[Prof_Cookie50]

@Prof_Cookie50 can you not send it back to them for them to diagnose and rectify the problem?
that's why you paid a pretty penny for the warranty (even if you have to pay for the extra component to fix the fault)

which part of the uk are you in? if you're close to brum i can have a look lol

I can send it back for like £60 shipping which is why I went for the cooler first as it was nearly the same price.

After the rewire we are down to 50/60°c idle, so I may leave it off overnight to cool after being sat at 100 for so long and hopefully jobs a goodun.

I'm Devon/Cornwall so bit of a trek. Lol

 

[Prof_Cookie50]

what have you done exactly? was something not wired quite right?

I took all the new wiring out, and then re followed the instructions to plug it in again, I think I may have mixed up where one of the pin connectors goes.

 

[Prof_Cookie50]

you connected the Y-connector incorrectly didn't ya

Maybe

 

[Prof_Cookie50]

looking at the hwmonitor screenshot, from the values for cpu and fan rpm, i would has a guess to it being a pump issue in regards to it being too slow to move enough water to cool the cpu guessing pump speed is slow and maybe the issue. what aio do you have?

It's a Corsair H60x elite 120mm

 

[Prof_Cookie50]

icue software installed at all

I have it now that it's calming down, I felt there was no need when idle it was at 100°c

 

[Prof_Cookie50]

So after letting it cool with the new AIO and then running it a day later it is now idle at 30°c and under load at 40°c so it all seems to be fixed now thank you all for your help. The only part that isn't working now is the new ARGB bits for the new AIO and fan.
