AMD Overdrive Temperature?

Hello, I was looking at my temperature in AMD Overdrive and it shows 8.8 Celsius for each core. If I use Piriform is shows 55-60 C idle. Which one is the most accurate and is 55 C hot for an idle COU?

Specs: AMD A8-5500 @ 3.2Ghz No turbo, 6GB DDR3 RAM 1600MHz, 1 TB 7200 RPM HDD,Asus AMD 7750 1 GB, Coolermaster Extreme Edition 525 watt PSU.

Thank you!

Dave

Around 30 degrees Celsius is normal for idle. Over 40 degrees on idle is indicative of an un-maintained CPU. You should vacuum or use pressurized air to clean your PC occasionally to keep dust from building up on the fan blades and heat sinks. Re-apply thermal compound roughly once a year or as needed.

Maybe use Core Temp and...

Sometimes I wonder about Overdrive's readings. It could be measuring the socket or board temperatures. If you look through the tabs on Overdrive you'll see the board temps listed. If it's identical to the CPU temps it may be mistaken. You can check temps through the BIOS or use RealTemp3.70 as I find those to be most accurate. If they correlate than Overdrive is correct. If not I don't know where it's getting those numbers from.

55 degrees Celsius can be very high for an idle temp, depending on your ambient room temperature and chassis' airflow. I have a Llano A8-3870k OC'd to 3.5 GhZ that idles at around 32 degrees Celsius with an ambient room temperature of about 20 degrees C. It hits 55 degrees Celsius +/- under full load.

EDIT: Also make sure that you are actually idling. Piriform or other programs might be in operation which could cause an increase in core activity.

Yes, so it is 50 Celsius idle right now @ 3.2GHz stock speed. The overdrive temperature is wrong as the board temp is the same. Ill try realtemp and get back to you on the temperature. Thank you!

Forgive me as the A8 is on my HTPC which is downstairs, so this might not be super-accurate. But if you open OverDrive and go to the tab with the core multipliers, you should see a circular indicator at the top right hand corner. When activated it turns green, when dormant it's either white or grey or something. That activates a certain performance preset for your CPU that you can determine. If you tinkered with the slider to the higher point and left the preset on, your CPU will force itself to stay at its maximum core frequency - 3.2 Ghz in your case. That could be causing an abnormally high idle temp even with little-to-no workload.

Ok, thanks for the fast reply but I have a slight option. When I go into the overdrive settings, it says my CPU is on turbo so I disable turbo, apply and click okay but when I restart my computer its back to turbo?! Any ideas why this is happening as I think thats my Im getting high temps.

EDIT: Im looking at overdrives temps and now its telling me 47 C. Also when I look at CPUID it tells me 70 C when I have chrome open.

What's the history on this CPU? AMD's driver's inability to save a setting aside, it sounds like this CPU is operating with no thermal paste compound on it. Did you buy it used or wipe clean the thermal paste off of it? Can you confirm the fan is operating?

Now that I think about it, I think Overdrive might be stating the amount of heat the APU is generating and leaving out the ambient temperature. If the total temperautre of the APU was 70 degrees Celsius, and your APU was generating 47 degrees Celsius, then the ambient temperature of the inside of your case would be 70 - 47 = 23 degrees Celsius. Which is logical. That might explain the mixed readings. But it still doesn't explain why your APU is operating at such a high temperature.

Okay I have to correct myself. I went down and checked my HTPC with the A8. It actually idles at 6 degrees Celsius, confirmed by the BIOS and Core Temp. My apologies I forgot RealTemp doesn't work with AMD. I'm not sure why Overdrive is reading your APU differently than mine. Although I haven't updated my Overdrive in over 6 months so it could be a new driver glitch not present in the one I'm using.

The discrepancies in temperature aren't nearly as important as the idle temps as read by the third party apps. Even 47 degrees Celsius at idle is strange. I'd definitely look into the fan/ heat sink. Check if they're covered in dust.

How do you check temperature with BIOS in widows 8? Sorry about my lack of knowledge on this stuff.

UPDATE: I'm pretty sure that CPUID Monitor is wrong cause it says my CPU is 106% when updating a game. Looking at Overdrive it tells me 30 C. Is 30 what is should be around?

I've been using Overdrive with my AMD 8350 (4 ghz) and it says I idle at around 50C (I touched the heat sink and it was definitely not 50C) but the temp reading goes way down under load. I have mine overclocked to 4.5 ghz and it's telling me the temp is under 25C during a stress test with the infamously ineffective stock cooler. I'm touching the heat sink right now and it is definitely not 25C. Any other temp reader will give me between 45-50C. It kinda seems like it's basing the temperature off of the fan speed. Although it's an okay tool for overclocking in my opinion, DO NOT use it to monitor the CPU's temperature.

Case closed.
