So after 20 years of building laptops, we still need to deal with this nonsense? Why couldn’t Dell build a better system?

all solutions seems good however, ultimately replacing Fan, and clearing the air way could be the p et best solutions. additionally update bios, chipset to latest version.

According to the BIOS disabling speed step “Places the processor into the highest performance state and prevents the Intel SpeedStep applet or native OS driver from adjusting the processors performance”. – So it sounds like it puts the processor at its highest performance state which would be counter intuitive to do when wanting to decrease the fan speed.

In reply to Jean-Sébastien. Speedstep should not increase power to laptop machine in any case, as to prevent heat issues. Laptop fan works all the time it is an irritating issue. Yes, Dell could have done better job with their heat management design, but it is what it is. Turboboost overclocks the CPU. You need to decide if you are willing to sacrifice noise vs performance, but the CPU at its base core clock should be more than enough for daily work related stuff (unless you are in ML or video or any high intensive work in which case do not use Dell 7400 laptop).

So you disabled Speedstep and TurboBoost. You basicly just tell the CPU to run at it’s lowest speed possible, which is below 2.00ghz in a U sku like this. And it won’t “auto-overclock” to 4ghz. So really not a good idea, unless you want a slowass computer.

Seems to have worked for me. Thanks for this!
