Temps from three different programs 

Direct Link: http://i.imgur.com/LyI7mqn.jpg

I have measured the idle temps of my box from three different programs and they all range between 42 and 57 degrees Celsius while the box ambient is around 30. Why is this so hot? Should I have opted for better cooling? Doesn't that void the warranty if I use something else for the chip? I'm kind of scared to launch a game knowing that the idle temp is this high...

(Please note that in the picture no games are actually running, those are just installers and/or setup screens).

And why is the temperature range bouncing around so much? It bounces around no matter which program I use (HW Monitor, EasyTune5 which came with my motherboard and AMD Overdrive). 15 degrees C is 60 degrees fahrenheit, that's a huge delta that it's constantly bouncing around.

Case: Coolermaster Full ATX Haf 932 Advanced Blue Edition

Processor: AMD FX-8350 Vishera 4.0 (Stock not OC'd) with stock cooler

Motherboard: Gigabyte GA-990FXA-UD3

Video card: XFX Double D FX-785A-CDFC Radeon HD 7850 2GB 256-bit GDDR5 PCI-Express 3.0 x16

PSU: Cougar CMX 1000 Cougar -1000CMX 1000W ATX 80 PLUS Bronze Certified

OS: Windows 7 Ultimate Service Pack 1 x64

GPU.

 

I had a GTX 570 with MSI's Twin Frozr cooler on it, which vented inside the case, much like your card. absolutly cooked my old 940. I went to a closed loop water cooler, and that helped tremendously. However, the GPU is cooking more than the CPU.

Your CPU core voltage also shows to be fluctuating a bit which will result in fluctuating temperatures. Perhaps something is running in the background (antivirus, etc) during those times you notice higher temperatures. .990 V may be true idle versus 1.416 V which would be working hard.

Also, other voltage readings look to be low like the +12 at 8.2 V and +5 at 3.4 V. I don't think this would cause the temperature issue, but may be something you would want to look into anyway.

Cheers.

Actually, I didn't even look at the voltage, but if the 12v and 5v rails are that low, then his PSU could be failing, or stressed, and dirty power does drive up temps as well.

 

Never heard of Cougar either...

Thank you all for your help.

 

Do you think this heatsink (combined with Arctic Silver) would help cool off the CPU considerably more than the stock one is now?

People always defualt to Arctic Silver, I prefer something else, Arctic Cooling MX-4 is good stuff, just as good on the conductivity, but non-conductive, so you won't risk shorting something else. a huuuuge plus.

 

Personally, I think CLosed loop might be the way to go. especially with a GPU like you have that vents into the case.

 

Buit this  is all semantics, your real problem seems to be voltage. Might want to check that PSU stat before it takes out your whole system.

This is a good air cooler for the 8350 as long as you don't go to crazy on the volts. Probably help with some better air flow. I would not trust that power supply.

I have a related question. Pardon me for asking, but what is the normal operating temperature and the maximum allowable temperature for the FX8350?

 

 

Edit; I think I found in here somewhere that it said 61c was the upper limit. I just want to make sure this is correct, and I do not know where to find this info.

I'm gonna give my own experiences with FX chips.

My idle temps, reported by CoreTemp, Aida64, HWMonitor, OCCT, and some others, fluctuate quite a bit among them.. Form example, CoreTemp says my idle temps are around 11°C, which is impossible due to the room temps: 28-30°C.. Good bye Thermodynamics..

If I run a stress test like OCCT, which has its own charts, I can peak as much as 75°C with no safe shutdown. Obviously, I had to stop the test, but not a single crash or hard reset due to the CPU safe temps. The max operational safe temp is 60-65°C..

Besides, asking in other forums, some people says that the FXs chips tends to missread temps.. I don't know what to believe, but of course I shouldn't peak at 75°C in a test without having a CPU safe-temp shutdown.. So maybe there's some truth on that..

Here, something to read (sorry if I post another forum's thread. If not allowed, please edit):

http://www.overclock.net/t/1318995/official-fx-8320-fx-8350-vishera-owners-club

In short, I don't have a "real" value of my CPU temps, just a mid term if I look all of them. Maybe you have to do something like that once you change your PSU.. Like most have said here, that voltage readings are not good..

Best regards...

My temps are stable, if I idle the fans, usually hovers in mid 30°C's, if I crank the fans, it'll goaslow as 17°C with my closed loop system. Under load, with fans cranked, usually touches just shy of 30°C, buuut... if mI want to preserve my ear drums, I don't care, let the automatic profiles do their jobs and be happy.
