Ps4 slim is noisy and overheats in DMC 5

Guys, good day. He dismantled the ps4 slim, replaced the thermal grease, had to chisk. Everything works, but after that the console basically became is noisy to work when playing Darksiders III sags fps and game lag, but it kind of bearable, I bought DMC 5, at the first start asked me to reboot due to overheating, but everything worked fine, today when you re-run and subsequent runs 20-30 seconds, the console begins to accelerate, a window appears warning about overheating, the fraction of a second, the console beeps three times and turns off. Prompt please, who can know what the trouble is and how to fight it?
