I'm the opposite to these guys actually - I don't monitor component temps, just coolant. Just different ways to tackle the same problem. My coolant goes up to 33C in Conan Exiles, I know my shit is working. I do it this way because my case has an onboard temp header and display for one channel, and I was sick of running Afterburner in the background for everything (in addition to CAM for the cooling/lights). So I plumbed it into a temp plug and set the CPU_FAN header to monitor pump RPM. Pump drops out - CPU FAN alarm sounds and shuts her down. Coolant doesn't spike while gaming - got an issue along the line somewhere. More than one way to skin the cat, pick whatever route you feel most comfortable with - the sagest advice here is definitely to 'keep it simple, stupid'
