PCH temperature

Pretty normal for a laptop. Like other components, it will throttle if it reaches critical values. It's safe to just ignore it, really. It also depends on the manufacturer what actual reading you're getting. You don't know if it's the actual diode or the package sensor, both of which can have significantly different readings.

I have a Lenovo Y740 laptop, repasted it a few hours ago getting excellent temperatures on the gpu and cpu while gaming(71, 76-80 receptively ) but then i have noticed that my PCH temperature goes up to 82-86c while gaming, idle temperature are around 46-48c, I was wondering if the temperature of the PCH is too high?

Pretty normal for a laptop. Like other components, it will throttle if it reaches critical values. It's safe to just ignore it, really. It also depends on the manufacturer what actual reading you're getting. You don't know if it's the actual diode or the package sensor, both of which can have significantly different readings.

I have just repasted again and changed the thermal pad thickness for the PCH from 0.5mm to 2mm , and the temperatures now are around 76-78c under load.
