Bought this laptop with the i5 1334u CPU back in march this year and am displeased with the CPU temperatures (I do enjoy this laptop in general), using Fedora Workstation 44 on it. My CPU slowly crawls up to 55°C during idle and stays there. Thats the minimum temperature and it rarely goes below that unless I put the laptop into sleep but when resume it starts again going up which turns me away from using this damn lap heater even though I want to use it. After the recent announcement of the upgrade to Core Series 3 CPUs I look forward to buy one (specifically the Core 5 320) but awaits feedback from you who bought the new mainboards first as I would very much enjoy a cooler running CPU. I use Freon as a GNOME shell extension to show me CPU temperatures but suppose any other application for that will suffice.
If your new Core Series 3 mainboard has arrived, can you give feedback here how warm the CPU gets during idle, light use and heavy use (whatever that is to you, I use stuff like MATLAB/Octave/Scilab, circuit and EM field simulation for that) and if you upgrade from the previous CPUs how much the battery life increases on average?
I have a 13 Pro, not a 12, but it strikes me that it would be worth knowing what temperature sensors generally go down to. On a fairly idle machine, my CPU’s two sensors are currently on 45°C and 50°C (and critical is marked as 90°C and 98°C respectively). My fan is not presently audible (and may be stationary).
So, on that basis, 55°C may only be warm in terms of normal CPU ranges.
Would you give us some temperature data to work with? Install this package sudo dnf install lm_sensors (though you may already have it) and then set up your sensors (sudo sensors-detect). I tend to say “yes” to the safe questions, “no” to the others. Then you can do sensors to dump a bunch of temperature data.
It is going to have a similar temperature. They are more efficient, but the thermal design for the FW 12 boards prioritizes quiet operation. In my own testing and with the MattBook, I have found that forcing the fan to run faster you can not get it below 45C in most situations. This is just the limit of the thermal design here.
I don’t say any of this to bad mouth the design. I think this designed for the market and type of workload it would be performing. But it is something to keep in mind.
I do think that the intake being right next to where the heat exhausts is probably impacting cooling efficiency some, BUT it is what allows things like tablet mode, and in general, a more robust resistance to the various ways people may use the laptop.
