I just received my new xps 13! Same issue! The fan will become so noisy when watching even a 15 secs YouTube video. I updated to the latest BIOS, but still didn't fix this problem. Will return it if Dell can not figure out by the end of this month...... It is really annoying and disappointed!!
I received mine one week ago. I've updated bios. When the workload exceed the 25-30% cpu, the fan start working at full speed. But the most annoyng thing happen when I close the lid. The laptop is supposed to enter sleep mode but it remains active and fans works at full speed. This is awkward!
All this behavior happens only when plugged to the ac adapter.
I've (temporarly) solved all my issues switching to quiet mode in the energy plan. It seems work properly now.
In any case I'm waiting for a proper fix from dell!

1) Check your Power options, to see whether you have proper action set when lid is closed. Here is some video that shows how to do it:
2) Problem might occur if you have bluetooth devices attached - device is waking up on mouse move when lid is closed:
Thank you for your answer... but I'm not a noob
1) I've already checked my power options in order to be sure that when the lid being closed the system willl goes in sleep mode.
2) No bluetooth devices are attached to my laptop.
I've had my 9370 for a few weeks now, and have experienced the same annoying fan noise as the rest.
In Windows 10, I had noticed the fan would run specifically when the WMI process (Windows 10 machine) would utilize a high percentage of the CPU. I browsed the event log for WMI and found the Dell Support Assist software to be the culprit. I uninstalled every Dell related software component, and that fixed the unnecessary CPU draw (and seemingly unnecessary fan noise).
I can still turn the fan on by running CPU intensive apps, but it doesn't just run for the **bleep** of it anymore. Not perfect by any means, but it's a start.
On the advice of TheCap 10, I stopped the Dell update service from running (runs in the Background), and what a difference. The fan is still there and pretty much seems to run all the time but it is super quiet. Pops up sometimes but that's to be expected. Now, if this will fix my "laptop won't go to sleep issue" I'll be set!
For those whose fans not only seem to go to 100% quickly, but also sound as if the fan blades are hitting a wire or something similar, I recommend exchanging your machine for another XPS 9370 of the same specs ASAP. Software "workarounds" are not the solution because the problem is hardware related.
My first 9370 had the issues some others described with the fans sounding like they were hitting something or were broken, somehow. So after taking the advice of others and updating Bios, as well as enabling quiet mode, my issue of obnoxious fans remained. I decided I was going to return the machine to my local Microsoft store, where I had purchased it the day prior. However, before doing that I decided to run the risk of voiding the warranty and opted to open the bottom of the laptop up and see if there was an easy solution, such as taping down a rogue wire that was hitting the fan blades.
However, after opening it up and inspecting the fans and surrounding area, I was unable to find anything that would be interfering with them. I used some compressed air to blow on the fan blades to get them up to speed. This allowed me to pinpoint the noisy fan. After touching the fan blades with a screw driver I discovered that the one fan had loose blades that was causing the rattle noise and there is really no way to fix it. After discovering this, I put it back together and drove back up to the Microsoft store, where I swapped it out for another 9370 of the same specs.
It's now been 2 weeks with the replacement machine and the fans are perfectly quiet, even after putting the laptop through its paces. So my advice is to exchange the laptop if you are still within your return period. But if you aren't able to do that the solution is really just replacement fans (2 fans built into one housing). Unfortunately, the 9370 is too new and I haven't been able to track down OEM replacement fans for it yet. But they will be available soon, I'm sure. And remember, you can't just buy fans for the old XPS 13" (9350/9360) because the previous models only came with a single fan. Meanwhile, the 9370 has 2.
