This is a C521 with a AMD Athlon X2 5200+. Usually I trust SpeedFan, its pretty accurate. But my CPU is at 4C? IS this right?

Looks like your board is not sending the right signal to Speedfan. If you're really concerned, you can try Coretemp, or Realtemp instead. You can also update the BIOS so that Speedfan can recognize the readings.

Not possible; you can't cool below ambient with air.

Is this the part where you tell us that you forgot to mention this is the start of your LN2 overclock experiment?

????? :heink:

I tried nTune, and it shows the "core" to be 40c. I can't tell which ones right. I'm pretty sure the chipset is a Nvidia 430

Yeah 4c is correct.

You have one of the new AMD chips that actually CONSUME heat and make everything cold. The harder you push it and OC it the colder it gets. Be careful of condensation. The heat sink in this case is used to HEAT the cpu, so if it gets too cold you will need a bigger one to warm things up.

You know what they say about stupid questions...

Ok, question for you. What is the temperature of the room the computer is in?

I think the thermostat says 17c, I live in Canada ;)

Ok, now use common sense and answer your own original question.

LOL! Thanks for the help orangegator, looks like it was just the BIOS. Its was giving me a hard time with the CPU clock speed too.

If anyones wondering about the c521 BIOS updates, use the 1.1.11 version it should recognize the newer Brisbane CPUs.

Yup, common sense.
Take a moment to think things thru. U will be amazed what you can come up with.

For example...

-My room temp is 25c
-My cpu requires a heatsink. Why? Because it creates HEAT.

Using those two simple facts we draw the following conclusions...
At rest (ie turned off), each individual component in my computer system should be 25c. Yes metal FEELS colder, but thats just physics.
Now as soon as we apply electrical current to a device, like a cpu, its gonna generate heat. Hence the need to dissipate that heat via a heatsink. So... this device that generates heat cannot POSSIBLY be colder than room temperature, and certainly nowhere NEAR freezing.

If all else fails crack the case open and feel the side of the chip or heatsink. If it doesnt feel freezing, it probably isnt.

So you upgraded the BIOS and solved the error of temp readings. You are on your way to becoming an expert troubleshooter.

Then Blame Canada for the low temps.

Am I the only one noticing this:

Found HDS728080PLA380 (80.00GB)

Looks like its not reading the CPU but that, which looks to be a HDD. but still 4C for a HDD is kinda low unless its in sleep mode..... but it wouldn't be able to read temp in sleep mode, would it?

Run CPU-Z and see if your CPU is a Brisbane core and a G1 or G2 stepping (or revision as it says in CPU-Z). If it is, you'll never get accurate core temps because the Digital Thermal Sensors in those particular CPUs are flawed and report stupidly low temperatures. Although this is not the cause of your original problem.

 

@jimmysmitty: SMART is not.

So SMART is still on even when in sleep/low power mode meaning its possible it was reading his HDD or an extra HDD instead of the temp. Or at least it seems that way because my Speedfan never had my HDD listed, just my CPU.

Yes, it is a Brisbane 5200+ with a G2 stepping.
