Planning to custom tune a new Legion (i9-14900HX / RTX 5070) to keep it under 70C. Thoughts on this specific setup?
Hey guys
Looking to pick up the new Legion 5 with the i9-14900HX and RTX 5070 (it's just the cheapest tho). Honestly, I absolutely hate laptops running at 90C+ with fans sounding like a literal jet engine. I want a quiet and cool machine even if it means sacrificing a tiny bit of performance.
Mostly playing heavy stuff like STALKER 2 and Marvel Rivals, so I’m I want to try a specific power profile to maximize efficiency.
Here’s what I’m planning to do
lock pl1 to 45\55w (pl2 to 60\75w).
disable most e-cores in bios (leave like 1-4 for background stuff).
cap max p-core clock at 4.0-4.2 ghz so it stops chasing high voltage.
also a basic -80\-100mv undervolt.
so my logic is that with 12 e-cores off, the whole 45w budget goes straight to the 8 main p-cores, so temps should ideally sit around 65-69C while keeping like 90% fps.
had a long ass discussion with a guy who knows his stuff and he said this setup should actually work ( with ai too )
or screw it, should i just pay a premium to get the core ultra 255hx / amd ai 350 and tune that instead? (huge money for me btw, rn the price gap between the i9 and 255hx is over $150-$300, and for the i9 vs ai 350 it’s more like $250-$400). But if i just pay $100-150 more, i can literally grab a 5070ti setup lmao. I know the difference between the 5070 and 5070ti (12gb vram and all that), but it just doesn't fit my budget right now (honestly even the 5070 stretches my budget, but it is what it is)
anyone tried capping the i9 to 45-55w in heavy games\heave ue5 games? what are your real fps and temps? thx a lot
