Latitude 5330 - Loud Fan

JakeBloomfield,

6. Launch " Dell Power Manager ", and then click " Thermal Management " in left pane.
7. It shows 4 thermal settings where you can select your preference. (The default setting from factory is "Optimized" which balances performance, noise, and temperature.) We suggest to select " Quiet " setting where cooling fan and processor speeds are lowered to reduce fan noise. This configuration may also reduce system performance and raise system surface temperature.

Hi @DELL-Jesse L ,

I mentioned in my OP that I have played around with the Thermal Management profiles to no avail.

I have exactly the same problem. When CPU reach more than 8% for few seconds FAN start to spin. I have most recent drivers. Quiet mode is NOT the solution. It spin also all the time with lower RPM. Sometimes in sleep mode also! I call Dell support they replaced fan and motherboard also. No change. This is issue with processor used in Latitude 5330 - i5-1245U. This notebook is not suitable to use in silent places. Very bad choice.

Hi Martin,

I confirm I have the same CPU configuration. I can tell that this isn't a hardware issue, but more to do with the specific fan curves that have been set by Dell. I know 12th gen Intel chips can get hot, but the fans should spin up at a higher temperature, or allow the cores to boost a bit later.

Same here. Brandnew Latitude 5330 with Intel Core i7-1265U. Fan runs almost all the time and is really annoying. The fan is also making a high frequent noise. Dell technician already replaced the fan but this did not make a difference. Power Management is set to Quiet. I'm only using this laptop for office usage (RDP over Citrix, Acrobat, Outlook, Teams). Fan only stops when the machine is complete idling for maybe a minute or so, then the CPU temperature goes up and the fan runs again. This device is just sooo annoying. This a is not a gaming device, this should be a compact portable laptop. So DELL team, please do something against this!!!

Any official response from Dell on this?!

I know 12th gen Intel chips can get hot, but this is a low end laptop SKU and isn't really acceptable.

I recently got a Latitude 5430 (i7-1265U), coming from Latitude 5420 (i7-1185G7). I am experiencing the same behavior, fan operates frequently plus based on temperature readings from HWinfo CPU can get hot,  it often spikes to 100 then throttles down, guess that's Intel Turbo Boost in effect but definitely can conclude that Latitude 5420 ran much much cooler and was silent even with heavy loads. One reason could be that Dell went with a single thicker heatsink in Latitude 5430 compared to dual heatsink for Latitude 5420. It is baffling to me why they would do that - which is essentially a downgrade on thermals - when they are going with a 12th gen which has 2 P-cores in them. Someone please explain to me because at the face of it seems illogical. I'm no thermal expert but still very curious

Heat and ventilation are issues with pretty well all modern thin laptops. Always use the laptop on a hard surface, never on a bed, couch, pillow, etc.

You might want to do what I did:

I took a strip of lumber, about 3.5 cm. wide x 2 cm. high (1.5" x 3/4"}, and the length equal to the width of my laptop. I routed out two notches to accommodate the laptop's rear feet. The rear of the laptop sits in those notches, propping up the rear by 2 cm. That provides better ventilation underneath the laptop and makes it easier for the fan to draw in air via the bottom vent.

It's cheap insurance, and also positions the keyboard at a slight angle that makes typing more comfortable. It won't solve a major heat issue, but it helps somewhat.

You can also reduce heat caused by Turbo Boost by changing power settings.
Settings | System | Power & Sleep | Additional power settings | select your plan | Change plan settings | Change advanced power settings | Processor power management | Maximum processor state: set to 99% or lower.
If you set it to anything below 100%, Turbo Boost will not activate, so system will not generate as much heat and you will save battery power.

Let me explain what happened to the 5330 in the meantime. The first Dell technician replaced the fan. Since there was no improvement, the second Dell technician replaced the mainboard and the complete heatsink. Some days later the 5330 began to put itself to sleep several times during MS Teams sessions leaving a message in Windows eventviewer that the system was put to sleep due to thermal issues. Dell support then decided to replace the complete laptop. For some days now I have a new 5330 (unfortunately again with the 1265U CPU) which creates the same fan noise but at least its stable. After adding a registry DWORD value to see processor power management in Power options I have set max CPU to 99% which filbert recommended and the device is a bit quieter now. Interesting side note: Choosing "Optimized" in DELL Power Manager Thermal Settings makes the laptop quieter than choosing "QUIET" mode. Although its a bit better than before I'm still not happy with the device as it should be completely silent during Office usage when the CPU is working between 3 and 15%. I had already placed the laptop on a bunch of old CD covers on the left and right side so the bottom has about 10cm of space to the surface of the table but that did not change the behavior. Laptop is always used as a desktop replacement so there are not even the warm hands on it.

Hi olwi, I am having the same issue but my fan only runs on some short periods(20 seconds). As i had mentioned it could be due to the Intel Turbo Boost coupled with the fact that the 1265U has 2 performance cores which get activated. But i totally agree on light usage this should not happen. I think for the fan it could be since it is a single heatpipe it has to work hard to maintain good temperatures for a 10 core processor. My previous laptop (5420) had dual heatsink pipes and the fan ran much quieter to main the same temperature as a single heatpipe would for 5430 if that makes sense

Dell scheduled a onsite technician to replace the heatsink as well and subsequently if problem persists replace laptop but I highly doubt that there is a issue but just a consequence of design and processor. Did they change a fan of a new design or did they install dual heatpipes instead of 1?

HI!

Actually I don't know if any of the replaced parts had a different design. I just gave the laptop to him and he returned it after he had finished the repair. And as I said, I got a whole new laptop now. Interesting fact: I have tried several CPU temperature monitoring tools (HWINFO64, CoreTemp) and when I look at the temperatures of Core0 and Core1 I see huge jumps within seconds which seems weird to me. Example: Core0 is at 52 ° Celsius, next second at 95 ° Celsius, then at 45 ° Celsius, then at 72° Celsius. Since it is a leased device by my company I guess I have to live with it. With reducing maximum CPU performance to 99% it is definitely better. And since its winter time now I only have a room temperature of about 20 ° Celsius which cools the device also. Will be interesting what the device will do in summer when room temperature is up to 25° Celsius.

Yes, I use HWINFO64 to monitor the temperatures and I agree the Core0 and Core1 are usually the ones with the most spike in temperature. These are probably the the 2 performance core whereas the other 8 cores are efficiency cores. Usually performance cores are present in 'H' category intel processors that are most of the time present in gaming laptops which have better colling (2 heatsinks/liquid cooling). I guess considering that the behaviour is normal

I had the exact same issue... I updated all drivers from the Dell support site (the automated way). Now the fan is completely silent. I think they recently fixed that issue with latest bios update.

I have all updates installed that DELL support page (the German one) shows me for several weeks. Problem actually got worse. The laptop's fan now runs all the time without any break. But if you say that it solved your issues I still have hope that it will fix also mine.
