It seems that the Lenovo is using the 80 watt one. I feel the only difference is the VBIOS. So flashing is a viable solution if you can get a compatible bios file from a vendor.

Given that Lenovo’s 2080 tops out at 72 Celsius I feel there’s more headroom that can be achieved before hitting the 90 degrees mark. With some regreasing of the TIM and finishing of the heat sink contacts, there’s a possibility of a little bit more headroom as well.

Can overclock manually. Works in 10 series Max-Q but not sure 20 series can do it or not

Exactly. No need repaste since the stock paste is good

Erm no . They might have cut the cost on motherboard power circuit as well . However you free to try smile.gif and tell us the result here if your motherboard doesnt burn .

10 watts is hardly much difference in terms of power electronics. Plus it’s easy to see how much the circuit can handle based on the FET RDS/On if you’re going to crack open the lappie anyways lol. Actually I wouldn’t even mind going past 100 to a 120 max most of the time, depending on board component density.

I don’t really foresee it being much of an issue. I’m actually thinking about clearance for thermal pad use and if possible use the backplate cover as a heatsink.

90W TDP has a higher clock = better performance

I come from the old generation, we want everything faster and hotter lol.

But I'm looking at getting some thermal pads of varying thickness to see if I can use the metal bottom cover as an additional heatsink.

blink.gif ?! so you mean you stick different thickness thermal pad to fill the gap on chip and heatsink and use them to transfer the heat to outer cover side d ?
but doing like that doesn't that mean you always need a cooling pad below your laptop ?

Yesh. Well, it's additional cooling, so if you put a cooling pad of course it'll be better, but if you don't it won't harm the lappie either way.
