Extremely High Graphics Card Temperature running MCE2005 full scre

Discussion in 'Windows Media Center' started by Ford F150 Guy, Jan 7, 2005.

  1. Hello

    I recently purchased a Dell Dimension 8400, with the following specs:
    3.60 GHz P4 w/ HT (enabled)
    1GB DDR2 533MHz RAM
    250GB Hard Drive
    ATI Radeon 800 XT PCI Express Graphics Card w/ 256MB of RAM
    2 ATI eHome Wonder TV Tuners (Dual Tuners)
    Creative Labs Audigy 2 ZS
    LG/Hitachi 48x CD-RW
    NEC 16x DL DVD+/- RW

    I am running my system with two displays, my primary monitor is a 17" LCD
    connected via DVI-D and my secondary display is a 51" widescreen HDTV
    connected via component video.

    When using Media Center, I typically run it full screen on my HDTV. The
    problem is, I keep hearing the GPU fan cycling on and off in my CPU and it's
    loud enough to be quite noticeable.

    Unfortunately, Dell does not provide for any kind of hardware monitoring
    that might tell me the temperature of the CPU, Memory, Hard Drive or Graphics
    Card. (I did ensure that the PC has adequate ventilation.) Upon further
    investigation, under advanced display settings, I found the ATI Control Panel
    does tell me the temperature of the GPU on the "Overdrive" tab (PLEASE NOTE:
    I DO NOT HAVE OVERDRIVE ENABLED - the GPU speed reads 499MHz).

    So here's the deal... when running Media Center full screen on my secondary
    display (51" HDTV), the GPU temperature stays right around 80 Celsius (or 176
    Fahrenheit) - this is when I keep hearing the GPU fan cycling on and off as
    it hits 80 Celsius.

    However, when I run Media Center in a window on my secondary display (51"
    HDTV), the temperature is typically around 54 Celsius (or 129 Fahrenheit) and
    I don't hear the GPU fan at all. I'm sure the fan is still running, it's just
    not at a high speed.

    I know the "simple" solution would be to avoid running Media Center full
    screen, however, becuase I have a rear projection TV that is highly
    susceptible to screen burn in, I would prefer not to run Media Center in a

    I'm not sure if it's relevant or not, but I did download and install the
    latest Media Center 2005 compatible drivers from ATI, as follows:
    Graphics Driver: ATI Catalyst 4.12 - Display v6.14.10.6497 and Control
    Panel v6.14.10.5134 dated December 13, 2004
    eHome Wonder Driver: v1.17.24.223 dated November 8, 2004

    Does anyone have any suggestions? I'm just not sure what to think at this

    What's the issue? When you ask your graphics chip to generate a huge HDTV
    display using textures and hardware stretching, it also generates heat.
    This should not be a big surprise.

  4. Thanks for the reply Tim. Believe it or not, the resolution on my widescreen
    HDTV is only set at 856x480. In terms of computer displays this is a very low
    resolution (by contrast most 20" LCD's are 1600x1200 and most 17" LCD's are
    1280x1024). My best guess is an ATI Radeon X800 XT with 256MB of RAM should
    have no problems running two displays simultaneously - especially considering
    this graphics card is designed for this functionality.

    In any case, I finally have a solution to the problem. ATI released Catalyst
    Driver/Control Panel version 5.1 today (1/17/2005) for Windows XP Media
    Center Edition. After updating to the new driver/control panel, the graphics
    card temperature now hovers right around 56 - 57 Celsius, whether I'm running
    Media Center full screen or in a window. Previously, the graphics card
    temperature would quickly jump from 56 Celsius when Media Center was running
    in a window, to 80 Celsius as soon as Media Center was Maximized and would
    cause the graphics card cooling fan to rapidly cycle on and off. The fan
    noise was VERY pronounced and could be heard during quiet passages in both
    movies and TV (Live and Recorded).

    Hope this info helps someone!!
