    I'm looking at this HP pavilion 15 laptop that has a core i5-8300h & 1050ti. Now the power plan is set to balance and the CPU usage is below 10% and it's turboing to Max 3.9 GHz on all cores all the time. This is an issue as the cooling system on the laptop sucks.

    Why is the laptop turboing all the time? I thought turbo boost should only kick in when it needs it. Instead it's boosting all the time generating unwanted heat.

    If I change the processor state to 99 it locks the 8300h to 2.3 GHz. I still want it to Turbo boost, just not all the time. I only want it to turbo when the usage calls for it.

    What was it set at?
    What is your expectations for when it should know when to 'turbo'?

    Is it actually turboing "all the time" or is it just boosting to turbo states when lightly loaded - are idle clocks set when at near 0 utilization?

    You want the CPU to turbo so it can get work done and go back to an idle state sooner.

    If you want to mess with the heat output, I'd install Intel XTU. Apply a undervolt and try scaling back the TDP setting. This will allow the CPU to still turbo while generating less heat under your new parameters.

    See if there is a turbo boost lock in your bios

    Sorry man, but after Zen was released on laptops, Intel totally overreacted and started setting WAY more aggressive turbo bins in their processors. Even if it resulted in a a higher TDP than the official rating :(

    It's much higher performance than their predecessors, but in exchange OEMs (or users in this case) are held responsible for making that performance work CORRECTLY on each platform.

    I still can't believer you can buy a Core i5 8400 for under $200 that turbos at 4GHz on all six core, but change is a good thing :D

    Right now, I repasted and have it locked to 2.3 GHz base clock and undervolted. It now idles at 35c and gets up to 70c during stress tests and gaming. This is a lot better than before when I was getting 55c idle and upwards of 95c during stress tests.

    But again, If I enable turbo boost by using power state 100% (there's no bios setting for turbo boost. It's a very locked down hp insyde bios) in power settings it'll boost to 3.9 GHz on all cores. My afterburner graph shows CPU usage at a steady 10%. Then my usage across cores looks like a straight line at 3.9 GHz. Each individual core does fluctuate but most of the time it's at 3.9 GHz.

    My cousin's laptop which has 7700hq runs a low idle temp and stays at 1GHz and if he does heavy processor load it'll boost to the appropriate clock for the given task.

    Where mine doesn't care and is always boosting to it's Max frequency which I don't want. Again, my power settings are set to balance and not high performance.

    Sounds like to me good old HP never learned from the early 2000's that they need a better cooling solution. My HP DV9535NR had heating issues and I NEVER went back.

    my Alienware has the i7 7700HQ and no issues with temps at all (max to 68'C). Either that, or the heatsink itself is uneven making cooling uneven. That sucks you have to play with turbo settings. Have you tried running Intel XTE and drop some vcore?

    I'm using Throttlestop and have it undervolted by -150 offset. I also have turbo boost disabled. If I have turbo boost enabled during high usage the thing still gets up to -95c. But I noticed with other laptops with the 8300h run hot too. At first, I thought I did a bad paste job but when I checked it looks like I got good coverage.

    I've repasted twice now and I'm getting slightly better temps from stock paste. The heatsink design isn't that great, wish they used separate pipes for the CPU and GPU.
