Quote from: Ke on April 08, 2024, 07:15:47I found fan loud on my gen12. I am only browsing youtube playing 1080p60 video and no other task running. The noise level goes to 35db in an quient environment with 28bd background noise. I compared it with my 2021 latitude 7400 in the same environment with same task, the noise on latitude 7400 was around 28 with is almost inaudible. I wonder if I have bad luck got this one with some issue or this generation is just like that. I contacted Lenovo, they told me to upgrade BIOS, which I did. Nothing changed after.

Quote from: Chuck Davis on March 09, 2024, 23:24:34For 90%-95% of the time I use the Carbon X1 as a desktop, with an external monitor, keyboard, etc. In this configuration the lid is closed.ThinkPads are designed with that specific use case in mind (because of docks) so you won't have any issues.
Quote from: Chuck Davis on March 09, 2024, 23:24:34I have read elsewhere that the Gen 12 moved the cooling fan exhaust to the keyboard. You don't mention this, so is this (partially?) correct?No, that's wrong, here are the fans and exhausts, below the lid at the bottom, when the lid is up/open or when it's fully closed they are freely open in both cases to push hot air outside the chassis, nothing is blocking them unless you block the bottom part of the laptop (placing it on a blanket for example): https://imgur.com/a/j3XBHYv
Quote from: Chuck Davis on March 09, 2024, 23:24:34Does running with the lid closed reduce cooling efficiency? If you re-ran the benchmarks with the lid closed, would performance be reduced?Heat goes up, everywhere and with everything, laptops are not exceptions. So unless you flip it (bottom up, top to bottom) there will be some small performance loss like with any laptop with good cooling solution, but unnoticeable outside of benchmarks.

You have to use a docking hub like a CalDigit or Lenovo's own hub.)Thunderbolt docks, yes. I have this one at work in the office, just one cable to my X1C and that's it; dual 4K screens running fine with a plethora of other ports if I need them, plus power delivery of course: https://www.lenovo.com/us/en/p/accessories-and-software/docking/docking_thunderbolt-docks-(universal-cable-docks)/40b00135us
