Yeah you have to sacrifice some performance for reliability too, by lowering the VRM temp by 10C you could make the capacitors last twice as long.
Capacitors usually have endurance rating of 2000-5000h at 105C depending on brand, at 95C its lifespan is doubled. There are no thermal sensor on capacitors and VRM (or not exposed to users), so you never know if they are overheating or not, you just know when they die. When I opened my laptop to repaste, I noticed that the inductors and capacitors do not make contact with the heatsink, they will build up heat over time.
That is probably why some OEM put some stringent PL into their Laptop (Dell put like 10W PL into their laptop), as to improve their reliablity. Some industry numbers mention Laptop have a failure rate of 30% in 3 years.
For me I run PL1/PL2 of 45W and I'm happy with the performance and fan noise.

Yeah inverted motherboard is a pain to take apart ~_~
