    Very nice machine in every other aspect, except for the noisy fan that I've learned from reading here and elsewhere that HP does not recognize as a problem.

    So, I'm thinking of replacing it myself. Can I do that without voiding my warranty? What about having an authorized HP repair center do it for me, if I shell out for the fan myself?

    Any ideas of what fan to use? And is there a service manual around?

    Cheers
    Dd.

    Also, another thing. Sometimes the fan goes at full blast from start up and refuses to step down over time. When taking a look with Speed Fan I notice that Sensor 1 reports 69'C (!), while both cores are 30'C and everything else 20-42'C. I guess Sensor 1 is the GPU, but can this really be accurate and require fan at full speed?

    My ATI graphics settings are very moderate and power settings are on maximum power saving. Changing power settings makes no difference.

    Exhaust air feels very cool (cooler than the room) and the machine is also at most lukewarm on all sides. Could this be a bug that makes the fan pump more air than needed? Any ideas for a fix?

    Did you try switching off 'Fan always on when plugged in' in the Bios. Also have you made sure you have the latest BIOS. If the GPU is really 69C I think the high rpm is justified. Maybe do some stresstest on the GPU and look how the temperature changes/sensor works.

    BIOS: 68PDV Ver F.04. Yep, turned off 'Fan always on when plugged in' about the first thing when I got the laptop. :)

    Yeah, I was thinking that it might be a faulty reading of the temperature as 69'C sounds like a lot from ice cold off to ten minutes later with casual office/browsing/etc.

    Did some stress testing on CPU and GPU. All other sensors are heating up and cooling down as expected, but sensor 1 seems stuck at 69'C. Thinking that if BIOS is misreading the sensors it might be why 8530-series are a bit noisy. Tried to report it to HP through the support, hope Mr. Vijay (?) will pass the information down the engineers.

    I couldn't find any sequence of hexadecimals that might be candidates for fan speed settings. Anybody done this on a 8530p?
