Videocard hotter with less Speed?

Discussion in 'Nvidia' started by Wolfgang Lange, Oct 6, 2004.

  1. Hi,

    I´ve lately bought a new GF6800GT (MSI) and I thought I could save a little
    energy by lowering the Corespeed for 2D apps - but the coretemperatur and of
    cause the ambiencetemperature are increasing - does this mean a higher

    Is anyone here able to tell me more why this happens?

    Is there any way to save energy with this gfxcard by changing the

    I think it has more to do with Fan speed throttling down as well.

    When I crank up my 5900FX from GPU 400 MEM 900 to GPU 475 MEM
    950. The temperature on the card goes down...??? I believe the fan
    is throttling up to compensate and being more efficient.

  3. Good Idea but I can´t hear any Difference in the Cooler-Sound. I don´t think
    it´s slowing down.

  4. This card got hotter when downspeeding from 385 to 315MHz.

    The in Aquamark3 it gets faster and cooler - and than warmer.

    Shortla IDLE.

    Then 2 x Doom 3 Timedemo demo1 and it get really warm.

    After Doom3 the card stay on 385MHz for a While in IDLE and gets colder - up
    to 56 degrees...

    Now it run on 315M;Hz again and feels 66 degrees agein.
