XPS 15-9575, fan noise, tent mode
After updating the BIOS and setting the maximum processor state to 90% in power management, my new XPS is now pretty much silent in laptop mode. In the tent mode, it's the opposite: The fans start immediately when the display angle exceeds 180 degrees and keep the keyboard reasonably cool. The laptop is great and this is very annoying. It only happens when you move the display through 180 degrees. Fans turns on straight away every time. I have tried both active and passive System Cooling Policy settings in power management, but did not notice any difference between those.

I can report that the Problem does not occur for me with the latest BIOS 1.7.1 . (I had not tried 1.6.1, so the change might be there, too). I tested with an HD Youtube video in full screen and there are no audible fans in either tent and tablet mode. With the same video running, the fans consistently started with previous BIOS versions (higher than 1.1.7) upon switching to tent/tablet.
As there was some confusion about version numbers recently, let me be clear:
I hope this sticks. Took 9 months, but thanks anyway. to Dell

Same kind of problem. If hinge is at an angle greater than 180 degrees the fan comes on. At idle (in this position) the fan is at low speed, but not silent. With a few tabs open in firefox the fan noise is at a significant level. Flipping the computer below 180 degrees and the fan shuts off completely and stays silent during much harder workloads. If I use it in tablet mode and use onenote the fan goes on and off, fluctuating. Also tried to change cooling profile.

Same problem with me. As soon as I changed to tent mode the fan goes on even though temperatures are below 50 degree Celsius. Once I put back in normal laptop mode fan shuts off. This started randomly today. I did update the bios to the latest one about 4 days ago. (1.1.9 )

I think it must be the new bios. I am currently on the 1.1.9 and switched back to 1.1.5 and solved the problem. Hopefully we can get dell to look into it for us.

Workaround = I switched the bios back to 1.1.7 and it fixed the problem as well.

I also had this problem with bios 1.1.9. Reverting to 1.1.7 seems to have fixed it.

I don't think that this should be marked as solved as reverting to an older BIOS (and then be stuck with it) is not a solution. There will surely be future issues requiring a BIOS update beyond 1.1.9

With BIOS version 1.1.9 and also after updating to 1.2.0. When I use tent mode on my XPS 15-9575, the fans immediately start to make a lot of noise. When I return to my laptop to normal Laptop mode, the fans immediately stop. I've ran all the possible tests for troubleshooting fan problems, but none have seem to help. I've also changed my power settings according to other threads on here, Max processor usage to 90%, passive thermal cooling, but to no avail. Is there anyone with the same issue that came up with a solution?

On 1.2.0 the issue still persists as well as buggy touchpad. Bottom half not always working and it is somehow related to AMD graphics card driver?

Same issue. Beginning from 1.1.9 Bios, my fans has got this strange behavior when entering the tent/tablet mode. Fans immediately turn on.

Other now merged thread about this issue with a Dell community manager responding (but not with a solution yet):

Hi, this does not seem one of the usual problems that are addressed by the fan noise help page.
I have the same problem on my XPS 15-9575 BIOS 1.1.9 as of now and the fan comes on precisely when the lid is rotated to or above 180 degrees. It stops immediately when rotating it back into laptop mode. This is in no way connected to the temperature, it also happens when the machine was idling and is completely cool. The issue completely negates the whole purpose of buying this machine, as watching videos in tent mode is no fun with the noise going on. When watching the same video in laptop mode the fans are silent but then I could have saved the money and got the XPS 15-9570. Otherwise the machine is fantastic and a joy, but this issue ruins it.
People in now merged thread about the same problem said that it started to happen with BIOS 1.1.9, when reverting to 1.1.5 or 1.1.7 it went away for these people.

Updated to the new BIOS 1.2 and not only do I have a random problem with the touch pad, the fan noise is back in Tent mode. Only solution I have is to go back to a old BIOS which isn't really a fix.
