My laptop is running on intel i5 7th gen + 8gig + nvidia. Lately(EDIT- Since the last few days), the temperatures seem to be 80ish even with casual browsing with little multitasking. I've checked sysguard *today and found spotify using 25% of the CPU. I've tried killing it from there but it just wouldn't budge. Finally used killall sigkill from konsole to end the process completely. The temperature then subsided after some time.
I'm concerned because the spotify process was constantly using 25% in the background even though I tried setting it to low priority, open-closed application or turned off internet. I've installed spotify and spotify-adblock from AUR.
