CX600 PSU Heat issue?

Recommended Posts

So I have a Corsair CX600 600 Watt PSU in my system that has a idle temp of 60-70 Celcius. The online specs say its idle temp should be 40 Celcius. Is this normal or could there be a problem? I'm getting these temps from CPUID's HWmonitor software form the AUXTIN TEMP status.

No.

 

The PSU is rated to run full output capability continuously at temperatures of upwards of 40°C. THAT is what the website says.

 

Like SpDFre@k said: There is no temperature reading on a CX PSU. Not one that a user can interface, at least. The temperature of 60 to 70°C you are seeing in CPUID is something else entirely.

 

"Hot to the touch" is very subjective. Is the PSU fan at least spinning?

The fan is spinning, Yes.

 

Also When I said "According to there website that is the psu temperature" I was referring to the HWmonitor software documentation, not the psu info.

As in the "AUXTIN" variable is the variable assigned to the psu temerature.

No. That's straight out wrong information.

 

You simply cannot measure the temperature of a PSU with software unless the PSU provides that information itself; such as the example of an HXi or an AXi series PSU. It is impossible for HWMonitor to monitor the temperature of a PSU that does not provide temperatures.

 

I don't know where those temperatures are being polled from, but I guarantee you those are not PSU temperatures.

I'm not saying your wrong I was adding info to see if you guys had any ideas on what its actually pulling the data off of. Since the temperature fluctuates it must be a component that is actually measuring it but I have no idea what it could be... That's why I'm here.

AUXTIN is a input on the LPC hardware monitoring chip. Many motherboards don't connect a sensor so the signal just floats and the "temperature" reported is meaningless. A good way to check is to look at what the BIOS reports. Do you have the ASRock utility installed? What does it report? There may be a file called similar to 880GXH*.xml. This can be read to see if AUXTIN is actually used on your motherboard.

 

Page 8 of the manual (ftp://europe.asrock.com/manual/880GXHUSB3.pdf) only specifies CPU Temperature Sensing and Chassis Temperature Sensing.
