Athlon II x3 440, CPU temps, One core 15+ degress hotter

Last response: in CPUs

Hey all, first post here, so if there is a sticky I missed, just point me there.

Running a new system, Temps in Speedfan showing

CPU1 35C
CPU2 59C
CPU3 40C
Core: 39C

This is an AMD Athlon II x3 440 running with no O.C. on stock fan.

Windows 7 64 Ultimate
600w OCZ power supply
GIGABYTE GA-MA790GPT-UD3H Motherboard

Ran OCCT for 1h and according to OCCT's temps nothing above 66C on any core, though OCCT doesn't show the core discrepancy that Speedfan (and SiSoft) show on Core 2, it shows all even.

Going to attempt to re-seat the stock heatsink tonight but just curious what to trust and if I should worry?

I would not feel comfortable with anything above 60C.
Also, when you reseat, do not forget to apply new thermal compound... and don't apply too much.

Anyway,
I find it odd that the temperatures for each core are different. In my experience, AMD systems, for each core, there is no more than a 1C difference. Core systems don't even seem to go past a 10C difference between cores.
Try using the program HWmonitor and make sure the readings are the same.
Since you say OCCT shows the same on all cores, I'm going to say there is a problem with speedfan. Or maybe there was a stuck sensor or something when you were using speedfan. Anyway, yeah that is too hot for my comfort, though you are still not hitting temperatures that are immediately damaging to the CPU. The TJmax for current AMD CPUs is over 100C. over 60C is still too hot for comfort though. What is your case cooling like? Any dust in the system?

No real dust in the system, cleaned it out with the upgrade. Case cooling is a 120 on front, 92mm on side and back plus PSU (bottom mount), using a Coolmaster Case.

Figured that it might be a misread, I'll check with HWmonitor later on tonight. Thanks :) 

Alright, values from HWMonitor:
Temperature 0 35°C (95°F) [0x23] (TMPIN0)
Temperature 1 51°C (123°F) [0x33] (TMPIN1)
Temperature 2 47°C (116°F) [0x2F] (TMPIN2)

Cores:
Temperature 0 44°C (111°F) [0x160] (Core #0)
Temperature 1 44°C (111°F) [0x160] (Core #1)
Temperature 2 44°C (111°F) [0x160] (Core #2)

Looks like speedfan was giving an odd number. The TMPIN1 matchs the BIOS, though the Cores stay lower. Under full load, they max at about 66C. Trust the BIOS temp or the core temps?

Oh, the BIOS temp scales with the core under load, usually staying 6-10 degrees higher.

Yeah that's normal. I've always just assumed that there was some kind of constant load while you are in the bios.

Hey, Thanks for your answers the other day.

So, under load temps are still high though it is totally usable. 69 degrees under full stress test. Heat sink is seated correctly. I have a 120mm fan in front for intake, 120mm fan side intake, 120mm rear exhaust. PSU sits on the floor of the case and pulls from a bottom vent. Using stock fans for front and back.

Using a ( http://www.newegg.com/Product/Product.aspx?Item=N82E168... ) on the side.

(Case: http://www.newegg.com/Product/Product.aspx?Item=N82E168... )

38C idle, 50C while playing wow+internet+music, 69C load.

Just not sure what else I can do? No O.C. going on, running at stock everything.

Well, for $10 a fair thermal compound applied properly can decrease temperatures. The TX-2 stuff lowered my temps from stock by 5*C, so it was an improvement. Plus if there was any problems with the heatsink seating or the previous compound, it could give the opportunity to fix any of that.

Life is good now. Turns out that the auto settings on the BIOS were overvolting the CPU, set it manually and boom, 57-58c under full load, 36c idle, 42c wow+web+music.

Thanks for the suggestions! :)
