Weird high power supply temperatures

[Muffinizedz]

Hey, I've recently turned my Server PC into a desktop regular PC. I changed out the power supply because the one one was 550W and couldn't support the RTX 3070 that I installed. Therefore, I installed a 750W Corsair RM750. 

 

Today I decided to check my temperatures and saw that "AUXTIN1" (which is power supply temperature) was at a worrying 95C. The other 2 psu sensors are below 20C which is even more perplexing.

 

My SS vvvvvvvvvv

 

 

Can someone tell me why this is? My other temps are just fine, and because this is really high temps I'm kinda nervous my psu is gonna die spectacularly

Your power supply has no data lines coming out of it to connect it to motherboard sensor chip. That is NOT what that is.

My bad lol, can u tell me what that is then xd? The reason I'm concerned is because it actually fluctuates a bit, so it must be connected to something??? idk

I cant other than there arent many components on a motherboard that can hit 95c. Motherboard VRMs could be it.

What the mainboard manual says?

Just read it, cant find any mention of it.

Z390 Steel Legend has a pretty poor VRM. What exact CPU is on the motherboard?

That is PSU temps if the PSU has like something to check temps, it does have a temp sensor but I don't know if that connects to the motherboard somehow. This reading is most likely wrong, you can check if the PSU is hot to the touch or when you see this happen see if the PSU fan is running.

AUXTIN is PSU temp, google before saying something.

[mMontana]

That software reports 3 AUXTIN values.

I doubt that might be in closed distance inside the metal case of the PSU.

 

Also, except the data connection for 12 pin graphics card adapter, AFAIK there's no data exchange from PSU to mainboard or viceversa. Only electrical connection.

Surely there is wireless communication between PSU and the motherboard right? LMAO. Surely a google search provides the correct answer every time right?

I showed you two sources, I can get more. Where is your evidence that this is not a thing, maybe this PSU does NOT have a connected temp sensor thats why it's showing random stuff which the second image said.

I have four more sources, still wrong? I have 5 sources and Tom's Hardware is a reputable source too. Please give me 2 sources that say AUXTIN is not a PSU temp sensor.

Spoiler

Would you please in your infinite google wisdom show me which one of these pins are used for data communication between PSU and motherboard? Dude you have NO CLUE about anything you are talking about here.

IT DOESNT HAVE TO BE WITH PINS IT COULD BE IN THE ACTUAL CABLES. Can you please tell me what AUXTIN is otherwise?

THEN SHOW ME THE CABLE, SHOW ME HOW PSU IS ABLE TO CONNECT WITH MOTHERBOARD AND CARRY TEMPERATURE SENSOR DATA. THE PSU OP HAS NO DATA OUTPUT OR INPUT CAPABILITIES.

 

AUXTIN stands for Auxillary Temperature Input, NOTHING ELSE, IT CAN BE ANY SENSOR CONNECTED TO CHIP ON THE MOTHERBOARD.

 

You are absolutely clueless and have no clue how stupid that post sounds by the way.

There is no way for the motherboard to get any info from the PSU, other than the PWR_OK signal, which just lets the motherboard know that the PSU is supplying power safely. It's just a motherboard VRM temperature sensor, and all of them are just sending bad data. No part of your PC is going to be at below ambient temperature.

It's not a PSU temperature sensor. The only info the PSU sends to the motherboard is the Power Good signal, which just lets the motherboard know that the PSU is supplying voltages within spec.

How about you just click the link and read context instead of doing Buzzfeed levels of research...?

 

Quote

CPUTIN is CPU temperature index, AUXTIN is auxiliary temperature index, and SYSTIN is system temperature index. These are all sensors on the motherboard. AUXTIN is the power supply temperature sensor, and SYSTIN measures motherboard temperature. Core temperature is different from CPUTIN as it reads from a sensor on your CPU.

From the context, it's obvious that the writer chose to use "power supply" to refer to the motherboard VRM, you know, the part of the motherboard that supplies power to the CPU and other components. It's not the wording people usually use in a PC context, but it's still clear and it's obvious what they're referring to when you read the context surrounding the sentence.

See above for the Linux article. Random forum posts are obviously not useful places to try and dig up information. They could be just as clueless as you, and also spread misinformation that they got by not reading the context around a sentence they got from Google.

I can do just the same thing as you, just look. A screenshot of a Google result, completely out of context that proves that the earth is about 6000 years old.

 

https://realfaith.com/what-christians-believe/old-earth/

 

Now, if you actually click the link, you'll see that that quote is horribly out of context, and the website does not argue that the earth is about 6000 years old.

Yes, still wrong. The THW forums are not THW, and is just as useless for information as yourself. It's not about the number of sources, especially when you're trying to take them out of context to say something that they don't.

Here is Intel's power supply design guide.

https://www.intel.com/content/dam/www/public/us/en/documents/design-guides/resellers-power-supply-design-guide-changes.pdf

 

You can check for yourself that AUXTIN is not a thing related to the PSU, and tables 4-1 to 4-8 give the pinouts for each connector.

In your mind, does each wire in each cable not connect to a specific pin...?

Technically, the PSU receives data input through the PS_ON pin to indicate that it should be on, and the PSU sends the PWR_OK signal to the motherboard to indicate that it's supplying power. But no temperature data for sure.

That's technically data, but all the pins do is connect to ground or not. Depending on which pins connect to ground, the graphics card knows how much power the PSU is able to supply. It's just the same as the 8 pin PCIe connector adding two ground pins (compared to the 6 pin PCIe connector) to indicate that the PSU is able to supply 150W instead of 75W.
