Question Intel core i5 3570 overheating

[DarkPassanger47]

CPU temperature are too hjgh on idle and load. On idle stays 45c and at load stays at 90c. I want to know if that's normal and possible solutions for the problem :/, the cpu fan are perfectly placed at the mobo, and i have 2 cooles, one on the side of the case, and one sys fan

The CPU heatsink may have come loose over time. If it is still the stock heatsink, you may need to replace it since the plastic deforms over time and eventually cannot maintain sufficient pressure for good thermal transfer.

I see. But the CPU are in good conditions i think, i bought a used one, but it seems pretty Ok. and the CPU stock are also pretty new, and the CPU fan are the assemblyng type, cooler box i think. Maybe the CPU fan are damaged ?, My Thermal paste are also a really old one, and also cheap
