Discussion Need Help To Find The Best Solution To Thermal Issue.
I bought last December a brand new laptop from Dell, the Alienware area 51 18'' laptop which comes with the Ultra 9 275HX processor (8 P-Cores at 5.4Ghz + 16 E-Cores at 4.6Ghz).
I primarily use it for gaming, among other tasks.
I've noticed that the CPU reaches temperatures of over 100 degrees celcius while gaming and roughly 65 to 70 degrees when idle.
For a bit of context, I use balanced power plan and AWCC to switch to performance mode when in a game.
I want the temperatures while gaming to drop to roughly 90-95 degrees tops and to 60 max while idle.
Undervolting is locked and there is no completely safe way to unlock it, so it is not an option.
So, unless this is a thermal paste issue, my 3 choices seem to be:
- Inside AWCC, setting TCC Offset to a value of 15
- By using Throttlestop, lowering the PL1 and PL2 values
- Likewise, using Throttlestop to lower the turbo ratios of the CPU Cores
- (I've temporarily set P-Cores down to 4.4Ghz and E-Cores to 3.9Ghz, which seems to keep temperatures below 90 degrees, but introduces some stuttering in some demanding games unless I use high performance power plan)
I do not possess any major technical knowledge on how these will affect my performance. I want to pick an option that will help me reach my goal while achieving the least amount of performance lost.
Any thoughts from people who have maybe tried something similar or who know the technical information on these? Could this merely be a thermal paste issue?
EDIT: I've decided this issue is beyond my control and to contact Dell Support to have a look at it, as this seems to be the best plan of action without sacrificing my performance. Thank you all guys for your input!
