7530 Fan Speed & Thermals - BROKEN
Dell Engineers, have you any thoughts about Fan Speed (constantly whirling) and actual thermals inside the 7530?
Below is a screenshot of the thermals of my laptop when it's doing almost nothing. The fans however, are spinning in 'medium' mode. If I jiggle with the Thermal Setting inside power manager I can sometimes get the fans to slow down, but not today! At the moment it's set to Optimised, but it I change it to Quiet, the fans actually spin up!
It would seem the fan controls are extremely manually and only change upwards...getting them to spin down (when the computing is under zero load) seems to involve me fiddling around with the Thermal Settings.
I would dearly like Dell to investigate this!

Have you checked your PCH temperature?
If it's skyrocketing without any I/O operations, then check your Advanced Power Settings, specifically, these:
If they are anything either than Maximum power savings, change them to that. This switches off unnecessary PCIe lanes that have no traffic, and keeps your PCH cool, too.

What utility are you using to look at the temps, and where do you find it?

Hi,
Please see my post below. I had similar issues under different circumstances but it helps clarify what is normal and abnormal for this workstation. Hope it helps.

HWinfo was useful to me in keeping a log of core temperatures and fan speeds.

All, I continue to have this problem, but it definitely less pronounced (perhaps an update has been made).
I do occasionally need to adjust the fan control if the fans get 'stuck'.
Many Thanks

Hi
I bought this 7530 to replace my 3 year old Lenovo P50.
Right now this seems to be a very bad choice because I have this issue where fans are running at warp speed.
The noice generated by this laptop is crazy...To the extend where I consider retuning it and remain on my P50 or buy another Lenovo which is ultra silent.
Amazing that an expensive piece of hardware as this is SO horrible to work with. If I was working in a machine shop I would not be able to hear the machines wrking only this jet engine trying to take off.
Luckily I'm only working with CAD (SOLIDWORKS) in a nice and quite office space - well, until introducing this State of the Art device......
Right now only thing active is this webpage - and fan is already more noicy than the P50 ever was during heavy workload.
Fix it...

All,
I dished out top $ for the 7530 with max bells and whistles coming from an Inspiron with horrible overheating and fan noise problems. I wanted a really quiet unit with which to record (my) acoustic music and was advised the Precision was it. But here I am, 4 months into use, and the unit has become as noisy as the Inspiron ever was. Not as hot, but just as noisy. Logic would dictate that it is either 1. a problem with laptops in general; 2. a problem with laptops in general and Windows; or 3. a problem with Dells. From other posts here it seems clearly to be 3. Dell EMEA Technical Support even admitted this to me (verbally). Very frustrating.

Felt I should reply to document that I have the same issues & frustrations. If anyone finds a solution or hears from Dell please reply to this thread!

I found a solution!
My Dell 7530 is now really silent when idle while this never happened before. Go to bottom paragraph if you don't want to bother reading the whole thing.
This was driving me crazy, and it took me a whole day of testing things to sort that out.
The i7 CPU in my machine was not running that hot (55°C idle 0-5% load, 70°C with moderate activity like 20% usage, check temps with CoreTemp or hwinfo), but the fan was spinning fast in idle and already like an Boeing taking off at low/medium load.
Here's what I did:
Bottom line: disable switchable graphics in the video options of your BIOS to use only your dedicated graphics card if you have one, that way your CPU will not use its integrated graphics card and will stay cooler and its load while doing office stuff won't bump as much, and the fan will spin much more slowly.
My CPU is now around 45°C, same for dedicated GPU, and CPU usage at idle state is most often below 5% with no more bumps while moving windows around or launching moderately intensive graphics stuff. I had to update to the latest video drivers for my nVidia Quadro (from nVidia website, not Dell) as my external monitors won't work after this change and to reboot 2 times as everything was blurry after nVidia drivers install but now everything works FINE and is almost dead SILENT!
PS: don't hesitate to try the other things I tested above yourself and make the changes that might work for you
Hope it helps some of you.

Thanks for the tips, I implemented them all.
For me finally the trick was to switch the CPU cooling to Passive
Power Options \ Change Plan Settings \ Processor Power management \ System cooling policy \
On battery: Passive
Plugged in: Passive
Also, I need to switch the profile in the Dell Power Manager to something else to make it silent. Whatever it has, it spins the fan, but if I switch it, it silences down.

My 7530 (Intel(R) Xeon(R) E-2186M cores + 128GB RAM), fans run all the time, and when there's absolutely nothing running or loaded except an idle desktop, the laptop's CPUs run around 132F.
I'm on the latest BIOS and firmware updates and I've tried to tune to to be quiet and cool, but it sounds like I'm standing in an enterprise datacenter.
As I type this, the laser thermometer shows the palmrest temperature to be 96F just to the right of the trackpad.

I have a laptop cooler under the 7530, and another one behind it blowing are against the back and under the laptop. It doesn't help.
I really wish Dell would figure this out, it's become a HUGE, loud annoyance in my office environment, and I can't take calls on the laptop because the noise from the fans is so loud, it drowns out my own speech on a headset!

Thanks for posting I will try turning off the switchable graphics in the Bios and use my dedicated Nvidia GPU.
I recently purchased this 7530 precision to replace my 3 yr old 7510, wish I hadn't bothered this 7530 with Xeon E-2186 CPU 2.9GHz, is constantly running at 4.21GHz. The fans cut in and out through out the day and it's extremely loud, I use SolidWorks and can see a drop in performance compared to my previous 7510 which had half the memory. I also had an issue with the AC adapter from new, Dell replaced the motherboard, HS and fans to get rid of this but occasionally it comes back.
