hi all ,
my build is I5 8600k , MSI Z370-A PRO Mobo ,16gb ram , 4gb Zotac GPU with Hyper 212 EVO cpu fan + 2 intake fan and 1 outtake fan inside a CM K380 ...
the idle temperature is coming around 60 to 65 deg ..... is this okay ?

what is the idle cpu temp for this build? and how many months we should change the thermal paste?

Not OK.
Your idle temperatures should be in the range of 10-15c. over ambient.
Your fan arrangement is good.

a) Was there a protective mylar cover on the bottom of the cooler that you should have removed?

b) Hyper212 is difficult to mount properly. Pay attention to getting it on level.

c) Did you apply too much paste?
Understand the purpose of paste.
It is to fill in microscopic air pits in the mating surfaces.
Air is a poor conductor of heat.
Paste is much better.
But paste is not as good as metal to metal contact.
Applying too much paste will act as an insulator; it is hard to use too little.
Application methods vary with not much real difference among them.
A small rice sized drop in the center of the cpu will...

A small rice sized drop in the center of the cpu will spread out under heat and pressure.

'Idle' can be a misused/confusing term.

In Balanced power mode, with all chipset drivers installed properly, if all goes according to plan, and with no real CPU loads occurring /applications running, the CPU should idle at near 800 MHz, bouncing around every few seconds to 1200-1800 MHz or so to finish a Windows housekeeping task, etc., with temps at 35-45C or so...

You thinking you are idle, but, potentially with WIndows updates being applied during a virus scan would no longer meet the definition of 'idle' while the CPU is running along at/near 3.5- 3.8 GHz or so...)

In task manager, what CPU usage and clock speeds do you see with no browser open/applications runnning?
