Hmm it seems Lenovo might have provided a more elegant fix for this.

But personally I don’t like installing nor running things if it can be avoided, thus I’d try the PowerShell commands first. Just run these one by one on an elevated PS window (run PowerShell as Admin):

 

  • ​​powercfg.exe /setACvalueindex SCHEME_BALANCED SUB_PROCESSOR PERFEPP 33
  • powercfg.exe /setACvalueindex OVERLAY_SCHEME_MIN SUB_PROCESSOR PERFEPP 60
  • powercfg.exe /setactive scheme_current

Re: X1 Carbon 6th gen : Fan Noise

Finnally I got also the well-known "coil whine" high pitch noise in the quiet evening or early morning.

 

It was nagging quite a while in fact, I tried to take off one by one the power plugs off the sockets thus to pin-point the coming ... such noise normally come from bigger (or high watt) power charger, suprisingly at the end, I found the coild whining noise (high freqency, low amplitude) coming directly from new my X1 Caron 6th!!!

 

Incrediable!

 

It is very low in loudness, but would be very annoying if people use to write in late night or in a quite office! I use to have sch noise while sing a 165W power charger or from a old LG LCD monitor (but can be eminated by change refreshing rate 60Hz -> 59Hz, or higher contrast).

 

Just like the “ tinnitus “  while people gets old and cannot sleep, or being punched duing fight in boxing. Terrible.

 

really disturbing.

 

Anyone has/had the same issue? how to solve this?

 

Does it relate to "dust guze design" (not that kind of noise) or can be solved by clean the dust inside?

Thank you! I've applied the fix from Lenovo already before, did'nt help me. Now did the manual Powershell Update again, here my current CPUz Output - doesn't get significantly better. Also the frequencies are still way too high from my point of view... is the microcode the right one? Anything elso I could do?

Hi again,


Ohh OK I wasn't aware that you've applied the fix. Sorry I'm not sure then :( and I'm also unsure about the Microcode sorry.

Re: X1 Carbon 6th gen : Fan Noise

Experiencing the fan problem in X1 Carbon 6th Generation, i7 - 8550U, 16GB Ram, DDR3 Base, PCIeNVMe OPAL2, Intel 8265 AC 2x2 + BT4.1, Y-FPR, HW TMP 2.0. Just got the laptop delivered today. The fan noise is constantly on even if I'm using just one tab in chrome and office outlook. Doesn't sound like normal.

 

Any solution?

Is this when you are plugged in to the AC? or with the battery?

Here's the link for the fix:

Make sure to have the latest BIOS (1.37). In power management, reset to factory settings first and than move the slider to the most left position (maximum battery life). This is what you can instantly do and will be most effective. I experienced the high pitch noise with all NIDEC / FURUKAWA fans (01YR203), had a replacement, did not help, sent the machine back.

 

Regrettably most X1C6 in Europe seem to have this fan, users having the other one (Lenovo Thermal module Delta - 01YR204) do not report the same issues. Same with keyboard, there are fantastic Chiclet keyboards around, whereas others are stiff und muddy (had it replaced as well, however, the initial one was much better, but here the left trackpoint button was loose). Same inconsistency with screens and SSDS... this could be THE ultimate laptop ever built. But quality control and thermal problems messed it up.

 

In case you get a great configuration out of the box you are very very lucky - keep it. Otherwise wait for the X1C7 or take a T480s.

Lenovo doesn’t use Chiclet keyboards.
