I have an AMD FX 6300 CPU with an Arctic Freezer A11 CPU fan. I was in the bios to check out its version and thought I'd check on the CPU temp. I am getting a reading of 60C at idle....just rebooted and put into BIOS. This seems way high to me.

Thermal paste is applied, fans are spinning. I leave for school this weekend, so I was hoping I could get some advice here.

Could the BIOS temp be wrong? Should I be using CoreTemp instead?

Thank you!

Absolutely. You should disregard the CPU temperature in BIOS, which is Socket temperature, and is calibrated to lookup tables coded onto BIOS that are often wrong. Since the source of the heat is created within the Cores, which are the hottest area of the entire processor. As such, it's always best to monitor Core temperatures, which are factory calibrated by AMD.

Thank you for the reply. So do you recommend the CoreTemp application? And what exactly would I be looking at within this program to determine my CPU temp?

Yes, I would recommend Core Temp. It's simple and straight forward.

Also, you might want to download and install AMD Overdrive, and while you're at it, please give this Sticky a read: An Understanding of Temperature on AMD CPUs and APUs - http://www.tomshardware.com/faq/id-2122665/understandin...

Thank you for your help. After installing CoreTemp, I am receiving a reading of 14C on my FX processor.

Sorry, but that can't be right. Core Temp is usually correct.

What is your ambient temperature? Standard ambient is 22C or about 72F.

Here's the temperature conversions and a short scale:

Cx9/5+32=F ... or ... F-32/9x5=C ... or more simply ... an increase of 1C = an increase of 1.8F

30.0C = 86.0F Hot
29.0C = 84.2F
28.0C = 82.4F
27.0C = 80.6F
26.0C = 78.8F Warm
25.0C = 77.0F
24.0C = 75.2F
23.0C = 73.4F
22.0C = 71.6F Standard ... or ... 22.2C = 72.0F
21.0C = 69.8F
20.0C = 68.0F Cool

No temperatures can be below ambient when using conventional air or liquid cooling. Below ambient temperatures are only possible when using below ambient cooling, which 99.999% are not.

I have downloaded AMD Overdrive. I am not quite sure what I am to look at.


I am running prime95 to stress the cpu. I have a reading from CoreTemp of 79C, while in AMD overdrive, I have a thermal margin of -8.8C. Not sure how to read HW Monitor as I don't know what pin corresponds to what.

This doesn't look good.

Gryz,

Don't depend on HWMonitor to give you accurate readings.

Please read this Sticky to interpret AMD Overdrive: An Understanding of Temperature on AMD CPUs and APUs - http://www.tomshardware.com/faq/id-2122665/understandin...

Please list your ambient temperature, which is always important because ambient directly affects all computer temperatures.

Also, please download and run Small FFT's using Prime95 Version 26.6 - http://windows-downloads-center.blogspot.com/2011/04/pr... - then list your temperatures.

CT,

I removed the CPU fan, removed the old thermal paste and applied a small dab of new. There appeared to be way too much paste under the heatsink, perhaps causing heat to get trapped there.

Here are the results after running prime95. What do you think? Looks a lot better to me, but still would like some reassurance. Thank you for your help!

BTW, my ambient is roughly 21C.

Yes, that definitely looks way better, but I see that you're only 1 minute into the test. What are your temps after 10 minutes?

Here it is roughly 12 minutes in.



Strange how CoreTemp dropped my TJ. Max to 70C instead of 80C. The 70C seems to be correct, however. That is, 70-24=46C which is what CoreTemp reads.

What do you think?

Also, is this "torture test" more CPU intensive than playing a game? What I mean is, could my temp ever be higher than this while gaming, or is this test the hottest it could become as it is using all cores at 100%?

Thanks!

OK, your temps are looking great ... and yes, P95 Small FFT's is more CPU intensive than any games. This is as hot as you'll ever get, unless, of course, your ambient temperature goes up.

Thank you so much for your help CT! I guess less is more with that thermal paste. Now I know for next time, or if I upgrade the fan again.

Thanks again!

I've had mailcontact with AMD today, or well, I got a reply today. The CPU temp is measuring the temperature of the CPU pins, and usually, the detected pin temp will be similar to internal CPU temp. AMD Overdrive doesnt read your actual temp, it shows how far you are from the thermal threshold (61.1C). And of course, that thermal threshold is a pretty big safety net..

And about stability and so on.. Its pretty hard to get a big OC stable on Small FFT's... And think about if you really need it to be stable for small FFT's.. I usually play BF4 to check stability of my OC. If it is stable, then its stable u know... Although, I do use "Blend test" to located any possible RAM instability.

Check out my new fresh Thermal paste guide, here in the CPU subforum. And according to me, skip CoreTemp. All you need is AMD Overdrive and HWinfo64.

I have the exact same problem!

I just installed a Freezer A11 cpu cooler on my new rig, and I realise now I used way too much paste, when I had readings of 65c+ (near to full load)! I had a panic, ripped out the A11 and shoved in the Stock. Now I'm getting readings of around 30c - 36c idle, and 58c - 60c on full load (gaming: Heroes and Generals, Americas Army, CoD, Battlefield)!

So I'm now going to try reinstall the A11, with a more appropriate amount of thermal paste! I'm using an FX 8350 and the last thing I want is for it to die!

Has anyone actually used the A11 on a FX 8350 and has an idea of full load temps? I bought it because I was advertised "full load max temp 38c"! So when I was victim to 65c+ I wanted to dash it at the wall!

After taking it off, I was the idiot, that needed to be dashed at the wall, for putting too much TP on! I will do the appropriate tests, as seen in this thread, and upload my results!

Hopefully I'm not going to have to buy a new cpu cooler!

I'm not phased for overclocking, just stock frequencies.

Thanks!
