    XPS 16 Idling Hot

    Hey guys, first post here because I couldn't find any issue like mine (maybe I'm just bad at searching. sorry!).

    The issue is that my Studio XPS 16 with the i7 720QM processor gets very warm even while only idling. Especially on linux, even while just browsing or even working solely with vim, lm-sensors reports temperature for the four cores in the 58C-62C range. In windows, coretemp reports that the idle temperature stay around 49C-54C range. According to what I've read about the laptop, those are unnaturally high numbers.

    It hasn't always been like this, but the computer gets uncomfortably warm even while I'm only browsing or working on some code. The fan is constantly on, even when I close the lid and leave it completely alone.

    If anyone has any answers for me, I'd greatly appreciate them. I'm not clueless when it comes to computers, but I am sort of new to hardware issues, so if you need info from any stat utilities, just point me to them and I'll put them up.

    Thank you in advance

    The 49C-54C idle windows temps seem normal, as I always get 45C+ idle on my M17x R2 with i7 740QM (using a CM storm SF-19 cooler on medium)

    The Linux temps seem a rather hot for idle temps though. I would not worry about that as it seems more like a software issue to me than a hardware issue as the windows temps are normal.

    49-54C is pretty much the standard idle temp for the 1645. I also run Fedora linux on mine, and my temps are a few degrees higher, but not that bad.

    I have a BIOS modding thread for the 1645 over here: http://forum.notebookreview.com/dell-xps-studio-xps/521990-bios-modding-gpu-oc-fun-profit.html
    It's mostly for GPU overclocking, but I've gotten quite a bit into fixing the DSDT, which fixes some BIOS bugs that Linux has with 1645 hardware. My modded BIOS fixes all the major errors that linux reports with dmesg, and improves hardware compatibility. It may help you with your problem. If you're interested in trying, read the first post, and then post a request in the thread for what you want.

    Thanks for the replies. I must have misread then haha. I thought I saw people mentioning their 1645's ran in the mid 30's and I was just like O_O

    But I think I will take a look at your BIOS edit. Maybe it'll help with the heat problem in Linux. Thank you both for your help.

    No laptop is going to run in the 30s. Desktops will, but a desktop heatsink/fan can weigh nearly as much as an entire laptop, lol.
