ideapad y510p cpu high tempereratur even in idle

Hey,

ive got a little problem regarding my y510p.
Last week I purchased the 8g ram, 755m sli, 4700mq version and was quite happy until I started playing.
The throttling began 2 minutes into the game (borderlands2) with fps before throttle: ~80 and after throttling:~ 20
I thought after checking some threads that the main problem would be the ultrabay gpu, but after disabling sli it still occured.
So i began the check deeper into the long y510p thread here and found interesting things about CPU overheating and throttling and undervolting as one solution.
So I undervolted with XTU by 80mv and bought a cooling pad. Both with no succes, the temps easily climb to 90°+ when gaming or benchmarking CPU.

Today I also regognized that my IdeaPad started getting really loud while I was learning besides it (Idle). The Tempereratur peaked randomly in idle to 80° (hwr said max was even 90°) with just skype and hwrmonitor in the backround.

So what is the deal here? Did I purchase a poor manufactued unit?
Eventhough some mentioned heating problems, I couldnt find one single thread mentioning heat spikes that high.

Thanks in advance guys,
I started getting in touch with the retour program from my supplier but maybe there is something someone could recognize without sending it back.
