7530 Fan Speed & Thermals - BROKEN

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:

• BIOS update: to the latest 1.10.1 from 2019/08/19 which was saying in the changelog things like "Updated the Thermal Algorithm to enhance the system performance.": didn't make any change to me
• Intel Dynamic Platform and Thermal Framework: I installed this as recommended elsewhere: no luck at all
• Power options (in Windows): as recommended also, lower max Processor state % value kind of worked as it prevents the CPU to work at max speed when needed but it's a stupid workaround to me to limitate the max CPU speed at all times while you may need it and you bought it for its speed anyway... so I restored 100%
• Power options (in Windows): PCI-E link state: some say this works, I didn't find it to make any difference but I switched from off to maximum savings anyway, this doesn't really slow down anything to me and avoids unnecessary PCI-E transmission when when not needed and that might help cooling chipset and CPU a bit
• Power options (in Windows)): from what I observed, set processor cooling policy to Passive at all times prevents the CPU speed to make the roller coaster too much and stay at reasonably low speeds while reaching max speed when required (app launch, computation, etc.), this somewhat works better and didn't make a noticeable perf drop to me
• Switchable graphics: that's the thing which worked best for me. This is meant to save power by using the integrated graphics processor in the Intel CPU when what you do isn't that intensive graphics wise and automatically switch to the more powerful dedicated graphics card (e.g. a nVidia GeForce or Quadro etc. if you have one) when you need it (e.g. CAD, games, etc.). But my thought was that the integrated HD Graphics chip geneates heat and makes the CPU hotter than using the dedicated graphics card for any display usage, so disabling it in the BIOS should keep the CPU cooler while not generating too much additional heat if your dedicated GPU isn't a toaster.

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.
