    CPU Running Extremely Hot


    Hi all, this is my first post to the forum. With Windows 10 showing up on more computers every day, I decided to take the leap and upgrade my operating system. I figured that I would need to know it in order to service my client's computers - however, doing so has provided me with a problem that I have been unable to solve.

    I have seen many posts and "solutions" for laptops that have suddenly been running far hotter since upgrading to Win 10.

    My situation is a little different, I am running a Dell Studio XPS 435T with the Core i7 920 with 12GB RAM, and HD5700 on the stock motherboard. The CPU is cooled by an aftermarket fan and heatsink (Arctic Freezer I believe). And yes, it is clear of dust bunnies.

    When booting into Win 7 Ultimate my idle temp is 43C and at load gets to 65C however if I boot into Win 10 Pro my idle is 67C and at load easily jumps to 90C+.

    I have also tried the "change CPU power" however dropping my CPU to 60% doesn't seem like a real solution to me...

    Any help would be greatly appreciated, thank you!

    Have you been to the "Drivers and Hardware" forum here and checked if you are running the current chipset drivers? Intel are pretty good with support in this area, despite having nothing apparently specially for Windows 10 - the 8.1 drivers are fine. They enable Windows power management routines to interact with the correct hardware, among other things. Also, visit Dell and see what they say about your system and Windows 10 support.
    Microsoft does sometimes get it wrong with their latest generic drivers, and only the older OEM drivers work best.

    Thanks for the reply!

    Looking at the update utility and checking back in the "Drivers and Hardware" forums gave me some vital information. My X58 chipset had support discontinued by Dell and Intel at Win 7, so my system is not able to run efficiently due to lack of drivers for 10. I'm surprised it even allowed me to upgrade.

    I appreciate your help, Fafhrd!

    That seems odd.

    Do you see a lot of CPU activity in the "performance" tab of Task Manager when the PC is supposed to be at idle?

    One way forward may be to investigate what happens under Windows 8.1. If possible, keep your current Windows 10 installation, and create another partition of about 20GB, it doesn't matter if it has to be a logical drive in an extended partition, if you have no chance to make another primary one, and download and install Windows 8.1 Enterprise Evaluation trial to that partition.

    Try Windows 8.1 Enterprise | TechNet Evaluation Center

    You will need to sign in with your Microsoft account and register, and you will get a few emails, but it's totally free. You can use it with rearms for at least 9 Months.

    The idea is to see if you can make that work better than 10 does, and keep reporting back comparisons to Windows feedback. Chipset inf files are only text files that add names for the various bits of hardware that link your processor to the rest of your system to enable the OS to hook into all the features available.

    If 8.1 does manage to keep your machine running within healthier parameters, then there's little reason why the same adaptations cannot be made within 10 - except the bloody-minded attitude of Microsoft towards older hardware.

    It's crazy that a generally well specified machine such as yours cannot run Windows 10, when I can run it acceptably well on a Pentium 4 with 2GB RAM.

    No, I don't. It's about 3% with my Carbonite running in the background.

    I will have to give that a shot later, if anything I may be able to help someone else out. This PC was originally a Vista so I think it was damned from the beginning.

    So, just as a follow up: I installed 8.1 Enterprise on a new partition to test your idea out. I ended up with very high CPU temperatures like before. Unfortunately the mystery appears to have been solved but not in the way I would have preferred. Back to 7 it is.
