The fan on my Lenovo Y50-70 got a lot louder after replacing the default HD with a Samsung 850 500GB SSD. I'm using theWindows 8.1 that came with the notebook. Chipset drivers are installed, Bios is updated too. AHCI mode is activated and everything is fast and fluid, but I really can't stand the noise of the fan spinning endlessly in the background when I'm using simple thing like chrome :S
