[SOLVED] What is your fan RPM? Quiz

Post by mintd »

Hi everyone,

I was wondering if you could share what your CPU fan RPM and temperature is under moderate usage (e.g. full HD/1080p video running on YT)?

My laptop fan is usually at 1400 RPM (and CPUs around 60C temperature) when idle/minimal usage, and then kicks up to 1800-2000 RPM (and around 60-65C) when playing a full HD video on YT. I tested this with Xsensors (in the Software Manager).

Is it normal for the fan to run at the RPM above? And what would you consider acceptable and noisy in terms of RPMs?

Thanks very much :)

You're on a laptop I guess? On my desktop with a YT 1080p video running my CPU Tctl is 40°C (20°C above ambient) and the fan runs at 450 RPM. My GPU edge is 35°C and the fans run at 0 RPM.

Acceptable noise from fans is none. If I can hear the fans from 1m away it's a crap build.

Yes, it's a (noisy) laptop.
450 RPM sounds very high?

450 RPM is low I think, at least for the 14cm fans I use. It's about 1/3 of max speed of these silent fans.

Laptops generally have smaller fans that thus have to run much faster to provide enough airflow.

Hi,

3000 rpm on my old "Gamer" laptop.

No idea which fan is which, have 2 "Be Silent" case fans, a Coolermaster Evo cooling the cpu (i5 7500) and an nvidia card.
I am watching streaming TV in 1080p, a dozen of tabs, thunderbird, telegram... It runs that cool and noiseless for years.
Haven't seen cpu temp going over 53°C (127°F). Sometimes in summer my PC is cooler than its environment.

Hi mintd,

Interesting question. I just read your post and the good replies to it.

My laptop is a Dell Inspiron 15 7000 (7573) convertible 2-1 (tablet/laptop quad core Intel Core i5-8250U) Linux Mint Cinnamon 20.3. I have noticed that the laptop runs warm and the room temperature is usually around 80F - 26.67C even with air conditioning. I don't know if it has a case fan and the sensors only show CPU fan when it is running. When the fan is running, it is barely noticeable, not loud at all.

To compare with your test I brought up a YouTube video at 1080p

Sensors:
System Temperatures: cpu: 69.0 C pch: 58.0 C mobo: 58.0 C sodimm: SODIMM C
Fan Speeds (RPM): cpu: 3184


Most of the time while doing typical computer stuff, the CPU fan does not seem to come on even when browsing with 70 + open tabs in Chrome. Usually runs around 2500 rpm when it does start up.

typical readings

Sensors:
System Temperatures: cpu: 57.0 C pch: 50.5 C mobo: 49.0 C sodimm: SODIMM C
Fan Speeds (RPM): cpu: 0

Sensors:
System Temperatures: cpu: 69.0 C pch: 57.5 C mobo: 57.0 C sodimm: SODIMM C
Fan Speeds (RPM): cpu: 2780

Yes 450 is very low actually. Sorry I misread it as 4500 RPM :D

Curious to know, do you also have a newer (gaming) laptop and if so what the RPMs are on that?

Thanks AndyMH.
Do you find the 3770 RPM noisy? Is it running at that speed most of the time (during general/light usage/idling)?

Interesting that you can see the NVIDIA (gpu) temperature and fan stats - only shows CPU on my system, why is that do you think?

Great stats, thanks very much phd21! Nice that your system runs quiet/silent most of the time :)

Hi,

I have no newer gamer laptop. On my laptop, part of ASUS Republic Of Gamers family, Nvidia GPU is permanently used, and the GPU inside i7 processor is disabled.

In today ROG gamer laptops, processor GPU is used for 2D applications, Nvidia GPU is used for 3D applications and for computation (OpenCL, Vulkan, Cuda...).

So, electrical power used is, in average, less; average heat is less; and fans rpm speed is less, except when the Nvidia GPU is used.

Regards,

MN

Currently my AMD Ryzen 5 CPU is at 32°C with my Radeon RX570 GPU is at 51°C with the GPU fan running at 241rpm's. That's using Mint Mate. In Mint Cinnamon it runs a bit cooler for some reason.

Thanks very much everyone for all your replies :)

Here's what helped me keep my fans quiet (with low RPM) on my laptop:

1) Used xsensors to monitor the fan RPMs (and CPU temperatures).
2) Used cpupower-gui to monitor and limit the CPU core frequencies (set to low/Powersave).
3) Installed Linux Mint Cinnamon Edge ISO.
4) Installed latest Linux Mint kernel (6.5.0-28) (in Update Manager).
5) Installed latest version of N'VIDIA driver (in Driver Manager).
6) Disabled discrete graphics (N'VIDIA) and used integrated graphics.

Thanks again!
