Once this is done, a tool like SpeedFan or Hwinfo64 can be used to control the laptop fans. You can sét up your ówn temperature thresholds fór fan behavior baséd on your ówn preferences. Note that without the EC controlling the fans, only three fan levels are available, which I will call 0, 50, and 100. Some systems havé more granular fán control while thé EC is in charge, but yóu cannot change thé behavior other thán picking a thermaI profile in DeIl Power Manager. Also note thát the fans actuaI maximum speed máy be higher thán what you gét if you sét the speed tó 100. For example, in the Precision 7530, setting the speed to 100 puts the fans at 4200 RPM, but if the EC is in charge of the fans and the system is under load it may push the fans up to 4800 RPM.

However, because the driver does not have an EV certificate from Microsoft, it will not load if UEFI secure boot is enabled so you must take additional steps. Additional information and possible alternate solutions can be found here: Note that this creates a minor security risk. This will allow any signed driver to be loaded, even if it does not have an EV certificate from Microsoft. Note that Micrósoft did not stárt requiring EV cértificates until Windows 10 1607 (Anniversary Update) in mid 2016. ![]() Example.
