Got my new Alienware X1 yesterday .. been noticing something odd - when I stress my GTX555 GPU via a game or benchmark and when the GPU fan reaches a certain high RPM it get's stuck at that RPM and never reduces. Unloading the GPU by exiting the game/benchmark back into Windows does not reduce the RPM - I've let it idle for up to 1/2 hour and the RPM has not decreased.Even resetting the system does not reduce the RPM - a shutdown is required. This is not an intermittent problem and is reproducible every time - the high RPM noise is quite loud and distracting.
Some details below:
When the RPM/temp are under 2600/80c the GPU fan functions ok - ie when the GPU load lessens, the RPM also decreases. However when the fan goes above 2600 RMP it quickly ramps up to 2900 - 3000 RPM and stays there - the RPMs never reduce after this.
Been talking to tech support and thus far they've only recommended upgrading the MOBO bios to A02 - that has not helped. Have an on going discussion with them and will keep you posted.
Has anyone faced a similar issue ? I'm thinking it's a Hardware issue withthe GTX555 card given that the card controls the fan RPM directly and even resetting the system does not help in this case - a shutdown is required.
Have Dell Support for your country send out a replacement video card to you. Your skilled enough to swap them out. Test the replacement and see if it has the same issue. Please post the results on this thread.
