Free program to check CPU temperature, clock speeds, etc.?

[mam8 esse grelo gostoso]

Hello guys. Recently I kinda "revived" an old Black Macbook Late 2006 with an SSD and maxed out the RAM. But the computer tends to get pretty hot, and even doing simple tasks the fan cranks up to maximum speed. Any way I can check my Mac's temperature for free? The program Intel provides for free does not support my CPU, so I don't see any other option.

Thank you! Have a nice day everyone.

Try Macs Fan Control. Not sure if they have an older version that supports your version of macOS though.
