HP dv6 7040tx overheating issue

As the title says, my laptop is a HP dv6 7040tx which has the following dual graphics cards:

1.Intel 4000

2.Nvidia 630M

I went through some sites and found that both my graphics card are being used. So, it was recommended for me to install Bumblebee.

I installed it and I used optirun to run my games. But, now my laptop is heating up! I was copying files over LAN and I'm downloading torrent files. There is not much CPU usage. It stays at around 5%. But, the sensor values read as follows:

acpitz-virtual-0
Adapter: Virtual device
temp1:        +86.0°C  
temp2:        +86.0°C  (crit = +120.0°C)
temp3:        +30.0°C  (crit = +120.0°C)

coretemp-isa-0000

Adapter: ISA adapter
Physical id 0:  +86.0°C  (high = +87.0°C, crit = +105.0°C)
Core 0:         +86.0°C  (high = +87.0°C, crit = +105.0°C)
Core 1:         +86.0°C  (high = +87.0°C, crit = +105.0°C)
Core 2:         +81.0°C  (high = +87.0°C, crit = +105.0°C)
Core 3:         +81.0°C  (high = +87.0°C, crit = +105.0°C)

Is there a s/w to control this or should I do something else?
