Hello! I would like to ask about the max temps that AMD FX 9370 processor supports..

I have a Coolermaster 612 PMW cooler and when I play some games (Civ V) my CPU temp goes to 59-63 C (using the Termal Radar software by ASUS)

Are these temps good for my processor? Should I buy a better cooler? Could you suggest me one?

I would appreciate any reply!

The max core temp is 61c but don't start freaking out your reading the cpu temp wich is usually 10 degrees warmer than the core temp ( wich is the one you want to keep a eye on) so your cooler is really not doing that bad of a job.

As noted the "core temps" are what count. You can download the software application "Core Temp" to get a reading on your core temps.

The CPU temp reported in BIOS and by a lot of software is not actually the CPU temp but the temp of the CPU socket thermister. This thermister runs from 10C-25C higher than the CPU "cores" so it should be ignored as it is meangless and a hold over from the days when CPU core temps could not be read directly from the CPU.

My 9370 under load is at 60C in the Asus Suite reading next to CPU.
Coretemp is reading 36-40C for cores. Should I be worried... Sorry bit of a noob and this is literally the only forum I could find about the chips max temps.

Also tried using the auto level up to 4.7 and Asus Suite gave me warnings because my CPU temp was reaching 68C so I bumped it back down to default. Wondering if those temps were ok, both default and OC.

Thanks

ASUS M5A99FX PRO R2.0
FX 9370(obviously im a noob)
Corsair H100i
GTX 580 SLI

Edit: Sidenote I called AMD and they said they have no official max temperatures so that makes me happy. (sarcasm) He said rule of thumb 61C for the CPU temp not even the core temp, Which I was exceeding on my OC attempt and coming close to if not on default settings.

Ignore the CPU socket temp, only use the core temp, and as a rule of thumb for Phenom and FX processors, you want to keep it under 55°C.

So just completely ignore Asus Suite and go with CoreTemp the addon?

Just worried me that it was giving me warning for reaching 65c but ok then I guess my OC was good getting good temps then?

Edit: Thanks for the reply, going to go back to 4.7 and see what my cores get to.

For AMD processor the CPU socket temperature is calculated by taking the measured value and putting it through a formula, which makes it pretty meaningless.

The socket temp is derived from a thermister mouted below the CPU socket and it is NOT the actual CPU core temp. The socket temp can vary 10C-25C higher than the CPU core temp because the socket has no cooling, where as the CPU does. The only temp that matters is the CPU core temp and 61C for 24/7 operation is the normal FX 8-core CPU max.

You can use the software program Core Temp to see the proper CPU core temp. as many software programs list the socket temp as "CPU" temp. which is very confusing and in fact wrong.

IME AMD tech support is quite lacking but every now and then then actually get something correct. The fact they did not differentiate between core temp and CPU temp is typical and troubling... IME the FX processors work just fine well into the mid-60C range unlike PII CPUs that mostly liked to be kept below 55C. All X86 CPUs produced in the last few years have thermal temp sensors that throttle the CPU frequency and vcore if they get above the desired max core temp. On the FX 8-core models this is 70C.

You can expect the FX-9000 series to all produce a LOT of heat as the default vcore is ~1.5V and the frequency is also high - both causing higher thermal loads than other FX models.

Do you think this I'm getting proper readings from core temp? someone said i shouldnt have tj.max 90c.  this was captured while playing bf4 on ultra settings.

Edit: 61c for CORE TEMP is what I'm watching for seems like I dont get close to that at all.

Then I don't know what you're still asking questions for.

If core temp is below 61C under full load such as when stress testing all cores @ 100%, then all is fine.

TjMax can vary by processor. I do not know if the FX-9000 series has a TjMax of 90C but core temp doesn't always list the correct TjMax temp. which is where thermal throttling cuts in to protect the CPU. Laptop CPUs/APUs tend to have higher TjMax temps as they have minimal cooling compared to a desktop PC.

Thank you both sirs, and I'm sorry for the redundancy I just dont want to fry my new pieces of plastic and metal.

Hello I have the m5a990fx as well. Paired with the Socket I have installed a Fx8350.

I dont know if something is wrong, Im cooling with a 212 EVO. Stock Load temperatures hit into the 50's? 51-52C Load. With an Ambient of 32C.

Previously I have also purchased a h100i. And I would go 4.6-4.7Ghz and the tempseratures would fly straight into the 80's-90's C . Later the unit broke and I have yet to buy another. But for now I use my old handy 212 EVO.

I have Oc'd to 4.7Ghz putting al Oc on the FSB Speed. Voltage on the cpu is 1.45V and with my motherboard it seems to add more voltage then what I set it to be. Which Is very annoying. But temperatures are now going into the 70's . ( 78C to be exact ) I could of kept the test going but i got scared. Socket temps stayed around 60C ( 62C to be exact )

Is this safe? Should I dumb down the OC.

I even today as of 3/20/14 . Re rigged my 212 evo to put a sp 120 on it. Then put a sp 120 as a rear exhaust. Air literally flys out the back as if it were a wind tunnel. And temperatures dont look to be even beeter. Not even by 1C. 

 

Please respond soon this is worrying me.

Just a note to all: You should start a new thread for a different question instead of appending an existing thread. It will get a better repsonse and not confuse two different issues.

The EVO 212 is a good upper mid-range cooler but not likely enough for an OC'd FX-8350 running 1.45v @ 4.7 GHz., IME. You will need a Top 5 or 10 type HSF to properly cool the FX-8xxx series with a 1.45v or higher vcore. Scroll down to the AMD section to see the top HSFs.

http://www.frostytech.com/articleview.cfm?articleid=2572&page=4

Don't get duped on the H2O cooling which independent testing shows is very poor compared to a quality HSF.

As far as temps are concerned you should be monitoring core temp, NOT CPU temp or socket temps which typically run 10C-25C higher than the core temp as displayed by the Core Temp applet.

The FX-8xxx series start throttling themselves when the CPU reaches 70C. Errors can occur any time you exceed AMD's specified 61.1C core temp.
