There NEEDS to be a utility or BIOS update to ALLOW Fan control on Dell xps 15, at the very least to Allow it to go into high performance fan speeds EARLIER. Can be a simple control utilizing Dell approved specs. 

I specifically need to increase my fan speed EARLIER (not exceeding dell specs) so that the computer will stay cool. My laptop is getting too hot, it is absolute NONSENSE to restrict this ability. It waits too long to cool down, Or doesn't even go into full fan speed!! You are shooting yourself in the foot Dell. Allow us to keep our laptops cool. Otherwise you will be replacing more units.

Please have one of your software engineers create a bios update that allows this ability immediately, within one week.

Again - WITH DELL APPROVED SPECS, so the fan speeds wont be overclocked or underclocked. Just an allowance on choosing the parameter. The motherboard control of fan speed is TOO CLUNKY and is making computers too hot. This will result in broken machines. 

This will ONLY be useful for your company AND your community.

I know some people complain of noisy fans etc, this is not the same thing. My fans are nice and quiet. TOO quiet, when they should be working. I've heard the fans at full speed and they should be there more often when it is required.
