idk honestly... $1250 for the 4800H + 1660 ti is kind of meh when the RP-15 with 4800H + boosted 2060 can be had for $1200. HP laptops, including the Omen lineup, historically aren't very good thermally. it does have a bigger battery, but thats at the expense of weight which is 5.5lbs. pretty sure you can upgrade to 62 wh anyway on the rp-15, which should put it very close to the omen.
HP says the new sensors are a first for any gaming laptop for more accurate skin temperature readings, steadier fan noise, and improved performance overall.
