The stock from the i5-4570 was replaced, the temperature in games dropped by about 10 degrees, the cpu package is 70-75 degrees now, in the native vent. with a percentage of the margin, there was not even more than 80+ degrees of temperature (there are no additional fans in the closed case). No squeak, no crackle. Overall, but the 300th series would no longer fit into a thin case. Still not for overclocking, dissipation up to about 90 watts.
