    No I never said the cpu was running at 45 watts, it actually was pulling about 20W at most, now it's pulling closer to 35-40 and staying at 80C average with some spikes to 91, but that's because of the cooler design i'd say as some of the cores only reach a max of 83. That's why I thought it was power limited initially, my first response states the amount of watts the processor was pulling under load, but reinstalling throttlestop caused it to pull the wattage it was supposed to pull. I'm also undervolted -.200

    What laptop cooling pads are people using and how effective are they?

    I've got the butterfly shaped one with 4 120mm fans. It lowers the temps a bit (a few C) at the expense of faint noise. Just noticed one of the fans went (after 3.5 years), so I'm eyeing another Chinese one with 5 140mm fans.

    You are correct that the power draw would be fairly small. This of course would depend on the particular fan and number of fans as well as speed. For example one model made by Cooler Master that has three fans draws roughly 1.2-2.3 W. That is why I described it as a slight additional load.

    I was amazed by this response so I tested this out and indeed, at least with my old and degraded pad, it looks like raising the rear of the laptop provides the majority of the benefit at load, although there is some very minor cooling effect provided by the pad fans at idle.

    Idle (1 min avg)

    1. No stand/pad - 47C
    2. Raised stand/no fan - 47C
    3. Raised stand + 3 out of 4 fans - 45C

    CB20
    1. No stand/pad - 88C
    2. Raised stand/no fan - 82C
    3. Raised stand + 3 out of 4 fans - 82C

    A bit disappointing - although the top left fan (right underneath the CPU fan) is dead - so that might partially explain the weak fan effect in CPU load test. ;) BTW If you undervolt you should be OK with the 180W brick anyhow - I get 67W max CPU power draw under TB.

    You can lower the CPU draw to around 45 W if you go into Alienware command center and set the "quiet" profile

    Since the latest BIOS update, it won't actually make the machine silent at idle though :(
