    Hi All,

    I have a question regarding a 7740. I want to run a machine that a) does not expel much heat b) reduces fan noise where possible.

    I am open to any configuration of the 7740 in total, with the questions around which components can impact these positively or negatively the most and what do people recommend?

    Usually go for no graphics (or a low powered one) as it's not really needed.

    My main usage is for usual work, browsing, chrome (with lots of tabs), emails, documents etc.

    Thanks!

    I'm curious; are you sure you want a Precision for this sort of work load? You could get by with an XPS 13 9380, or a Latitude; perhaps get a larger monitor if necessary?

    I can see the desire to have a well-built 17" system. There aren't that many choices out there for business systems.

    Anyway, just get whatever you want and use DellFanCmd (see my signature) plus SpeedFan to limit the CPU fan speed to 50%. I have tried this with my 7530 and it is very quiet at this speed. I've tried loading the CPU up with the fan capped at 50% and what happens is, it quickly throttles down to around 2 GHz to keep it from overheating. If you want to reduce the heat further than you can cap the maximum CPU speed using the settings in Windows advanced power options.

    Undervolt, repaste, and fan control as said above.
