Lifting rear 1/2"+ has made a huge difference.

i just bought my legion y540 (i7 9750h + gtx 1660ti) from a few weeks and during gaming on performance mode the cpu gets to 100c and then i notice a thermal throttling after reading in this topic I elevated the rear by nearly 1.5 inch and I got 5 degrees on some cores and 6 degrees on the another cores and i noticed the game run smoother and didn't find any throttling and the air flow in the vents became more stronger.

Re:y540 heat and BIOS issues

so I did what nexon said to the turbo ratios but I reduced cache and core to -125mv then tested games and didn't find any problems but control which I guess isn't the hardest game on cpu ran on 70fps maximum then drops to 40fps while the cpu temp was max at 74c. I guess I will need to reduce UV's numbers to gain some fps but then cpu will gain heat too.what should I do ?

What have you put in turbo ratio limits? You don't need to change undervolting

in turbo ratio i done what nexon said in page 4, I changed the pattern from up to down: 41,40,40,39,39,38 after i clicked "rest ratios" cause I found that changing the first ratio change the second one by the same number so after clicking this button every ratio change Individually. should I change the bios to gain some improve in temps so i won't need to do all that editing in powers and etc. or what ?
