Is this a safe temp?

[meritmaster]

I was playing "Rust" for a long stretch of time, and i started to get this horrible lag where i could not do a single thing.

 

I alt tabbed out, and closed rust, and my skype connection was really buggy, scratchy, and not exactly right. 

 

I closed skype; it stopped, and i checked my cpu temp. It reached 77 degrees! [on "core temp"]

 

I just built this computer again from an RMA, but i only RMAed my board, and video card.

 

Specs:

Cooler master haf922 {added side fan-fan blowing in}

CPU I5-3570k {stock cooler]

msi gtx 660 ti

Good cpu thermal compound.

 

Idling around 44 degrees core one 38 degrees core four.

For a stock cooler, that's fine

Even though i was experiencing trembling lag?

It probably lags, because of your graphics card, not your processor. You should check the temps on you GPU, because it is most likely that it is the thing causing the problems.

 

PS: Processor frequency starts to throttle when the processor reaches 95-100C.

I know in a lot of games, after a long time, no matter what, the game gets unstable. Seeing as rust is pre-release this doesn't surprise me

Why does the pick show that the max was 55C not 77C on core temp? If you took the pick after it is useless. Also why does CPU-Z show you have a i7 860. EDIT: Lol you were on the front page, not actually using it, my bad. 

Also The cooler is bad, and the game unstable, the temps are not critical either. 

Also i apologize if my tone seems unfriendly.

It's normal with the stock cooler, still not healthy for your pc. You should by a aftermarket cooler as fast as possible, it will make your life so much better.
