Any way to control the fan on a 5580?

Any way to control the fan on a 5580? Even when the CPU usage is 3-9% and the CPU is at 38-40°C the fan will ramp up and stay on at the faster louder speed. I can use the Dell Command Power Manager and set it to cool and back to quite and the fans will spin down but after a time it will ramp up again.

Thanks Robert but I'm looking for a way to control the fan. Looks like Dell has decided there should be no way to do this. That is their deal I guess but then the Dell Command Power Manager Thermal Management should be like spot on and it's not.

Hi, a have same problem with Dell Latitude 5490 with CPU i5-8350U, in minimal load, typically after start OS, is CPU i maximum frequency and fan still spinning on the crowded all the time. Dell support advised reinstall all chipset driver and flash BIOS the new FW version, but it didn't help.We're sad, our problems will be solved. If I wanted to feel both at the airport as for the noise, I'll get some server and not a business laptop.

Re: Any way to control the fan on a 5580?

It looks like there is nothing that can be done other than find a different port replicator that doesn’t use the Thunderbolt port or return the Laptop for one that doesn’t have this design flaw.

 I understand if Dell can’t or won’t make a change but this is a real issue and just saying it’s working as designed or releasing a technote about users incorrectly misdiagnosing a bad fan doesn’t change that fact that the fan is unnecessarily distractingly loud under very normal not at all stressful workloads.

 I don’t think there is anything in the sales literature letting customers know they are buying a much noisier than normally laptop because the Thunderbolt controller chip is inadequately cooled and that your new laptop will often sound like you are gaming and or coin mining even if you’re not doing anything and even if you run the CPU at half the speed you paid for.

 I’m disappointed in Dell. They need to fix this, offer another port replicator without using a Thunderblot port or its power draw if that is the issue and let the customer know. Everyone in the office that got one has mentioned it and we would not have gotten them if we had known.

 

Is there a way to help cool the Thunderbolt controller chip?

Is there a different port replicator that doesn’t use the Thunderbolt port?

Is there a Dell laptop with a Thunderbolt port that has adequate cooling for the Thunderbolt controller chip?

I have the same problem with this loud fan on model 5580. After updating to the latest firmware the only option that the fan will not make loud noise is to select "Quiet" option in the thermal Management , at the price of very slow cpu speed. Optimized, cool and Ultra Performance option is like sitting next to a jet engine.

Very disappointed with the purchase - what a waste of time and money to buy Dell.

Re: Any way to control the fan on a 5580?

Adding a "Me too"...  Dell Command Update shows that my system is up to date, so there don't appear to be any updated Chipset, Drivers, or BIOS Firmware.  The fan runs full speed even with about 10% CPU, 31% Memory,  7% disk, and 2% GPU.  I'm using a WD15 Dock, and I've heard that the issue may be a physical one related to the Heat sync for one of the Chipset chips (Not enough thermal paste, or not enough passive heatsink), so the fan runs to compensate for that.  I can try running without the dock for a while, but that's hard to do because everything is setup to connect using that.  I'm surprised Dell hasn't been able to produce an update to fix this if it's software/firmware or a recall/service-call to fix it if it's hardware.  We have a lot of these machines and many people complain about this issue, so it's not just my laptop.

Re: Any way to control the fan on a 5580?

Same here. With up-to-date firmware and drivers, the system fan gets really noisy after only 10-15 seconds at 100% CPU, in a room at 20°C (68°F).

That is clearly not the expected behavior, and I never witnessed something like this with the previous generations of Dell Latitude laptops.

Any idea out there?

thanks,

-Pierre

My 5590 costs just under $2,000 with warranty - Has an i7 Processor and 16GB Ram. The fan runs on this thing when doing the most simple tasks. Please help us fix this design flaw.

Dell released BIOS Version 1.13.0 on Dec. 11, 2018 (https://www.dell.com/support/home/us/en/19/drivers/driversdetails?driverId=R7PH8&osCode=WT64A&produc...). With this update the fan spins up at higher temperatures and with lower RPM. This is not perfect, but a lot better than before!
