I have a dell inspiron 7567

The laptop is 2 years old and hasn't had a thermal paste change, so that's probably one of the reasons the performance has turned to crap. But yesterday I put in an m.2 nvme 512GB SSD and everything was fine. When I started the pc up today I had much worse performance in League of Legends and Unturned, both games played the day before without issues. I did a clean install of windows that went like this:
Legacy boot usb drive -> SSD wasn't popping up in partitions -> went to bios and changed settings from RAID to AHCI -> go to install windows again SSD now being accessible, made partitions and couldn't install windows on the ssd because of 'gpt style partition' -> opened up CMD and cleaned both disks then installed windows 10 on the ssd. -> Downloaded everything on the ssd, discord, steam, unturned, league of legends. But performance is absolutely crap now, basically twice as bad LoL from 80 to 35-45 fps which go down to 7 fps at times and unturned with 20 fps.
I tried downloading geforce experience and updating drivers, changing power satings to "high performance" but still no difference. I can only assume i haven't installed the SSD properly or misunderstand how the compatibility between all the parts work. Would be grateful for any tips.
The ssd is some random chinese brand
