Overheating, Cant for the life of me figure out which component.

Ok heres specs: (Sorry for the wall of text but I wanna get as much info out as i can.)

Hardware (Everything running at stock speeds.) Copied from Everest.
------------

CPU Type: Intel Core 2 Duo E8400, 3000 MHz (9 x 333)
Motherboard: DFI LANParty DK X48-T2RS (3 PCI, 1 PCI-E x4, 2 PCI-E x16, 4 DDR2 DIMM, Audio, Gigabit LAN)
DIMM1: Kingston 2G-UDIMM 2 GB DDR2-667 DDR2 SDRAM (5-5-5-15 @ 333 MHz) (4-4-4-12 @ 266 MHz) (3-3-3-9 @ 200 MHz)
DIMM3: Kingston 2G-UDIMM 2 GB DDR2-667 DDR2 SDRAM (5-5-5-15 @ 333 MHz) (4-4-4-12 @ 266 MHz) (3-3-3-9 @ 200 MHz)
3D Accelerator: ATI Radeon HD 4850 (RV770)
PSU: OCZ GameXstream 1010w SLI.
OS: Windows 7 x64 Retail Ultimate

Cooling
---------

1x Rear 120m exhaust.
2x Top Rear 120m exhaust.
1x Front 120 intake.
PSU has a 120mm exhaust fan.
Stock cooler on CPU
Stock cooler on Video Card.

These are current temperatures after about 10minutes.

Temperatures
Motherboard 40 °C (104 °F)
CPU 45 °C (113 °F)
CPU #1 / Core #1 49 °C (120 °F)
CPU #1 / Core #2 49 °C (120 °F)
Aux 52 °C (126 °F)
GPU Diode (DispIO) 61 °C (142 °F)
GPU Diode (MemIO) 68 °C (154 °F)
GPU Diode (Shader) 69 °C (156 °F)
Seagate ST3500320AS 36 °C (97 °F)
WDC WD6400AAKS-75A7B0 37 °C (99 °F)

Cooling Fans
CPU 2411 RPM
Fan #4 1245 RPM
GPU 2728 RPM (34%)

Voltage Values
CPU Core 1.28 V
+2.5 V 1.10 V
+3.3 V 3.25 V
+5 V 5.00 V
+12 V 12.10 V
+5 V Standby 4.92 V
VBAT Battery 3.30 V

I'm under the impression AUX is the power supply temperature?

I'm fairly certain its not the video card overheating because the whole system shuts down, not just the display.
I'm fairly certain its not the RAM because its not exactly performance RAM.

Leaves the PSU, CPU and Motherboard.

If I use Everest's stress test (I un-ticked FPU), You basically get these numbers, thereabouts. Sometimes a little higher, sometimes a littler lower. Aux never gets above 85% before it shuts off.

CPU #1 / Core #1 75 °C (120 °F)
CPU #1 / Core #2 75 °C (120 °F)
Aux 82 °C (126 °F)

Now if I run a FPU stress test from cold start, system lasts about 20 seconds before it shuts off. Zooms to the temperatures above.

I can have the side open with a pedastool fan blowing at max into the case and it only postpones the shutdown a little.

Cheers.

  1. Ok quick update,

    I moved the PC downstairs, its generally 10°C cooler no matter what weather, here is the temp left idling for 30 minutes

    Temperatures
    Motherboard 32 °C (90 °F)
    CPU 39 °C (102 °F)
    CPU #1 / Core #1 41 °C (106 °F)
    CPU #1 / Core #2 41 °C (106 °F)
    Aux 40 °C (104 °F)
    GPU Diode (DispIO) 64 °C (147 °F)
    GPU Diode (MemIO) 70 °C (158 °F)
    GPU Diode (Shader) 72 °C (162 °F)
    Seagate ST3500320AS 32 °C (90 °F)
    WDC WD6400AAKS-75A7B0 33 °C (91 °F)

    Sadly, running the stress tests yielded the same results and shut off times.
  2. if its a hard shut off like pulling the plug from the wall then suspect the psu . Is the fan spinning?
  3. Yep, its just like I've flicked the switch off at the wall. Doesnt restart or anything. Fan is spinning, I even replaced the fan with a faster one and still had the same problem.
  4. Hi
    can you please read again voltage values and post them ?

    Cheers

  5. Voltages as requested.

    Voltage Values
    CPU Core 1.30 V
    +2.5 V 1.10 V
    +3.3 V 3.25 V
    +5 V 5.00 V
    +12 V 12.10 V
    +5 V Standby 4.92 V
    VBAT Battery 3.30 V


    Dont know much about voltages so if you spot something wrong, let us know.
  6. Well
    second line does not make any sense to me thats why i asked you to post this again
    can you please get all voltages from bios PC Health section ?

    Cheers

  7. I sent a message to OCZ tech support and they tell me if the PSU reaches 85 degrees celsius, then yes it will shut off.

    I'm buying a watercooling kit and a vga block tomorrow anyway, should fix the high temps during warmer weather.

    Seems I need to buy a PSU that is a little more resilient when it comes to heat.

    I'll let you know how it goes.
