Dell Precision 7760 -- CPU is too hot on any of 4 thermal profiles

We tried reaching you on a private message asking for the Service Tag number to ascertain the warranty but did not receive a response. Please feel free to reply to the private message whenever you are available.

Thank you! We have received the required details. We will work towards a resolution. In the meantime, you may also receive assistance or suggestions from the community members.

Hi, the issue I'm concerned with is obviously not related to my laptop configuration, it has place over all Dell Precision 7760 and 7560, and the laptops reviews in internet is a proof for that. But I wrote my service tag as you asked for.

Hi,
We hope you are doing well.
We haven't heard back from yet post our recent conversation.
Kindly reply to this message so that we can assist you further.
Thank you for choosing Dell.
Have a wonderful day ahead.

Regards,
Mary.

I've performed the following (as Dell support asked for):
i) updating all the drivers/firmwares and OS (I've done this for my both SSDs -- one with win10x64 and the second with win11);
ii) checking the issue under safe mode -- the issue is the same in safe mode;
iii) advanced full hardwear test (keep tapping F12 after laptop start) -- all passed, no errors.

Saying in addition, I'm all my life working in IT industry and I well understand the issue and its roots -- Dell should release new BIOS version, of course if they will to correct the issue, but not asking me but asking their BIOS department team.

CPU behavior is almost the same on all 4 thermal profiles  and 'Cool' profile is really cooler but by means of only GPU significantly less power consumption

Hi,

Hi,

Good Morning! It's me, Soniya!

Please help us with the thermal readings on the hardware test screen to further check. 

Run through the f12 test (capture if any error) and click on advance > system Info > health. 

This will indicate if the issue is seen outside of the operating system.

Dear Dell-cares moderator, as I wrote before (please read my reply on 11-04-2021 01:48 AM) -- I've done all hardware tests -- no errors there -- and the thermal readings on the system info / health page are not related to the problem ! As the problem is when there is CPU intensive workload ! But meanwhile, if you ask, the thermal readings on the system info / health page are (for CPU):
55 deg Celsius (current), 32 deg Celsius (low), 70 deg Celsius (high).

Today I've added the following information:

------------ how to check your laptop for the issue ------------

Give your laptop a really intensive CPU + GPU workload, for example Prime95 and Furmark simultaneously (www.mersenne.org, geeks3d.com), and monitor temperatures for CPU package and all its cores with HWiNFO (www.hwinfo.com). I run Prime95 with default settings and Furmark with my LCD panel's native resolution. Under usual room temperature, after only 5 minutes of the stress test there are CPU package at 100 deg Celsius almost all the time (almost constantly) and a half of cores (in my case 4 of have started to hit 100 deg Celsius. Having given the laptop only CPU really intensive workload (Prime95), the cores start hit 100 deg Celsius after approx 15 - 20 minutes.

This forum website has autocorrected my prevous post (of 11-08-2021 07:07 AM) and has made an error: namely, above "(in my case 4 of have started to hit 100 deg Celsius." MUST be "(in my case 4 of have started to hit 100 deg Celsius."

again mis-autocorrect by Dell !!!
MUST be "(in my case _4_ of _EIGHT_) have started to hit 100 deg Celsius."

Dell support asked me to check the temperatures and fan speeds using HWiNFO x64 utility by means of looking to the DELL EC heading under Sensors view. I suppose "DELL EC" stands for "DELL Embedded Controller". But using the latest of today version of HWiNFO (v7.14) on win11 x64, there is no "DELL EC" heading et all in HWiNFO interface, and the Sensor view does not list/show any fan's information anywhere. But there are all temperatures in the Sensor view there (not under "DELL EC" headings).

Dell Support please clarify the situation -- do you see on win11 in HWiNFO "DELL EC" on Precision 7760 ?
And what me to implement to see them ?

PS: my laptop came with 1 TB SSD with win 10 x64 but now I'm working with the same one SSD with the win11 only installed (fresh install) -- of course all firmwares/drivers and OS is up to date.

CPU temp is still in spec.  You are asking them to drop bellow spec, as this will also potentially lower performance?
