I sure hope Lenovo does something about it.

I trust you know it's a combo mic + headset (smartphone) jack,

and that you need an adapter to use standard PC mic and headphones?

The 1.21 is quite an improvement over the 1.19 BIOS. The fan noise is not too annoying anymore and in combination with a fan control tool, really acceptable under normal workloads.

 

For fan control I use thinkfan (linux), with the following settings:

 

[user@laptop]$ cat /etc/thinkfan.conf 
sensor /sys/class/hwmon/hwmon0/temp1_input (0)
sensor /sys/class/hwmon/hwmon2/device/temp1_input (0)
sensor /sys/class/hwmon/hwmon2/device/temp2_input (0)
sensor /sys/class/hwmon/hwmon2/device/temp3_input (0)


(0,	0,	30)
(1,	20,	70)
(2,	60,	72)
(5,	62,	75)
(7,	65,	32767)

 

The fan stays at 1900-2000 rpm (very very silent) for most of the time while answering email, browsing, watching youtube videos etc.

 

Big thanks to the Lenovo Team for the good work. It's still not perfect and the fan is really annoying while under heavy workload, but the laptop runs at an acceptable noise level for most of the time now.

Let's say I'd like to download tpfancontrol, what are the correct settings? Never used it before and don't want to do something stupid.

Wow, quite high temperatures. Can't you tolerate the level 2? For me it is essentially silent. For me, level 3 is definitely the step I don't want to take:

 

(0,    0,    57)
(1,    52,    66)
(2,    64,    68)
(3,    66,    70)
(4,    68,    73)
(5,    71,    76)
(7,    74,    32767)


However, 68 up/66 down (for level 3) is too bad really, I'm considering putting them >70 like you have. I'm a bit concerned with the consequences with running the CPU so high, but like someone else stated, it's definitely worth not losing your sanity.

Re: X220 - fan constantly on / revving up and down

Well, the settings from my thinkfan.conf are prior BIOS 1.21. I didn't see a need to change them, because the laptop stays at 58-61° C for most of the time anyway now.

 

I just tested the following setup a bit: 

 

(0,	0,	30)
(2,	20,	72)
(5,	62,	75)
(7,	65,	32767)

 

This seems to work fine now as well, having the fan operate at ~2900 rpm for most of the time, which as you said is indeed essentially silent. I think this setting should also help to keep the temperature rise under heavy load at a lower rate.

 

Thanks for the hint!

 

EDIT1:

I run the thinkfan as a deamon process, having set the biased temperature level to 0 (cmd line option -b 0). This really improves the noise level a lot, as the fan does not react to every tiny temperature rise, as if the laptop was about to explode.

Re: X220 - fan constantly on / revving up and down

A picture of my issue with the new 1.21 bios : (Am i alone ?)

 

from a cold boot, it will be like 40°  & 0rpm (no whine)

At ~45°, the fan start spin at ~2000rpm (fan silent + no whine)

At ~50~55°, the fan start spin at ~3000rpm (fan slient + whine)

At ~60°, the fan start spin at ~3500rpm (you can hear fan(absolutely normal) + whine)

etc

 

After that, if i stop stressing the cpu (go idle) then the fan spin down to 4000->3500->3000 rpm, and will stay at 3000rpm, even with the CPU at a super cool 38°. Never go to 2000 again.

(If i stress the CPU again, it will go to 3500, 4000 etc, and then stop, once again will never go below 2000rpm)

 

(AC or battery = same thing) And of course it happend also without TPFan started

 

 

I will use TPFan (to avoid the whine when i do no-intensive task) until i can get a proper fan (in the future)

Are you using any additional cooling utililties?

What hardware configuration do you use? I have the i5 + IPS Panel.

 

Even tough I use Linux, my fan runs most of the time at  2950-3000rpm and I can only hear a very very very silent whine if I am in a totally quiet room and listen very carefully. Right now for example, it runs at 2965 rpm and I can only hear the fan if I go I press my ear against the laptop. Furthermore when my fan spins at the beforementioned rate, the temperature never even gets close to 38° C. In idle mode it stays at 52-55° C. I haven't ever seen it go under 50° C.

 

I suppose you have the X220i with the core i3? That might be an explanation for your low temperatures?

I have the Core i7 X220 and my CPU temp drops to 45° at idle -- see here.

The thermal grease between your CPU and fan may need to be replaced.

I have the x220+i5+ips+7200rpm

 

I don't use any other software/hardware for cooling. And the windows install is still very clean.

 

Well i think i can obtain the very low temp of 38° because my fan still run at 3000rpm at idle. (with maybe 23° ambiant)

If the fan would spin down at 2000rpm, i think i should get ~45 like JNavas

 

 

 

If you get ~55° with 3000rpm at idle, this is indeed maybe a little hot, but what is your ambiant temperature ?

 

btw, at 3000rpm the "high pitched noise" on mine is clearly noticable but it can maybe vary from one model to another since like many other i don't think this is a normal "feature". However the normal fan noise (vent noise) is indeed very silent.

At 3000rpm i just ear a constant mosquito noise.
