CPU And GPU Overheating After Upgrading To 1333 MHz Memory

I had 8 GiB of memory in my HP Pavilion dv7-4110em XE287EA#BED working at 1,066 MHz because one of the 2 4-GiB memory modules had a maximum frequency of 1,066 MHz. Today, I replaced that module with a 4-GiB module which can work at 1,333 MHz. So, now my 8 GiB of memory works at 1,333 MHz. Windows work noticeably faster.

However, the CPU and GPU temperatures now go over 90C and the laptop goes into hibernation. Is there a way to avoid this - somehow slow down the CPU when the temperature is too high, or similar? How can I make the laptop go into standby instead of hibernation when this happens?
