    Hi

    My CPU (i7 7700HQ) reaches very high temperatures in games (about 95 C) and there suffers from thermal throttling, what actually makes the notebook useless in games. It happens in a few minutes after launching the game. The idle temperature is between 55 and 60 C while ambient temperature is between 18 and 20 C. I want to repaste CPU but I have no experience with notebooks so I would like to get some advices. Could you tell me what thermal paste should I use? In my dekstop computers I usually use GC Gelid Extreme but I don't know if it is going to be ok in notebook. I've also read somewhere that there are some "thermal pads" in notebooks. Should I replace them with a new ones? And is there anything more should I know about?

    use whatever high quality thermal compound you can get such as: MX4, Kryonaut, ICDDiamond, Tk3, GC-Gelid.

    Thermal pads are also in desktop hardware, altho usually only for passive VRM cooling or graphicscard vRM coolinng.

    In your case no thermal pads needed since you only want to repaste your CPU.

    After repaste it would also be wise to downmload CTU or throttlestop, then put the voltage offset to -75mv to further decrease temperatures.

    After that you should have a very pleasant experience.

    Ok, thank you very very much for the answer.
    Actually a few days ago I downloaded XTU and I set voltage offset to -90mV. Along to some guide at begin I tried -110mV but the notebook restarted.
    But I wonder if I should limit power available for CPU. Currently I've set "Max Processor Usage" for 98% in "Power options", so "Max Core Frequency" is about 2.69GHz.

    Nah power limit should be maxed out, it gets limited by the EX anyways. Max core speed should be 3.5ghz or something along the lines of that.

    So I will set it back to 100%. Before changing the voltage I had read somewhere that I should turn off the boost mode in this way to limit the temperatures.

    Once you repasted then that won't be needed. ALso you should never disable turbo since it does nerf your performance quite a lot.

    i agree with a repaste (higher quality compound does wonders compared to the factory stuff)... but there are a couple things to try if thats a job you're not comfortable with...

    for me I lowered max processor power management settings till I found a 'happy place' of performance when gaming & temps (CPU temps seem to run hot on gaming laptops at load)... also making sure the rear exhaust has room to breath is an easy thing to get in the habit of (for me I use 2 velcro straps rolled up on the 2 rear corners to keep the laptop lifted about an inch on a flat surface, but perching the end of the laptop on a book could be simple enough to cool a few degrees)
