    Laptop is arriving on Thursday, I'll let you know then. I'll likely re-paste and undervolt it, like I do to pretty much all my laptops.

    Turns out you have a point, seems the Y545 does get hot. I wonder if this is limited to the i7, or if the i5 also gets this hot.

    Also, did you undervolt your CPU? Seems to be a general consensus that the 9th laptops (especially the i7) really benefit from an undervolt. The laptops that run cool are often shipped with a factory undervolt.

    The laptop arrived yesterday, started playing around with it and doing some testing. Undervolting the CPU made a huge difference, about 10C drop in temps under load. Mine came with Optimus turned off by default ("hybrid mode" turned off in the Vantage software), turning it on made a difference too (no need for the 1660ti to be used when not gaming).

    Using a cooling/laptop pad also made a difference. I'll see if changing the TIM (thermal paste) on the CPU/GPU has any effect at some point.

    Instead of using cooling pad try elevating the rear of laptop by placing small object, 1 inch clearance should be there. Using balanced thermal mode will also lead to less temperatures than performance mode.
