Hi,
I built a new gaming pc the specs are below
i7 8700K
msi z370 gaming m5
2466 Corsair rbg 16 GB ram
500 samsung evo
750 wats corsair RMi gold
1080 Ti Msi trio Rgb
Case is 570x corsair crystal rgb

I am worried about my temps during games such as crysis 3. My MAX temps in hw monitor are

Systin 50 C
Cputin 66 C
Tmpin5 65 C
System 50 C
Tmpin3 67 C

I undervolted my cpu by -0.90 voltage ofset
So my max Cpu temp during crysis 3 is 72 C and the average cpu temp during gaming is 60 C

1080 ti never gets more than 67 C

Corsair rams max temp during gaming is 47 C and 45 C for the other module


The 570x corsair case has 3 fans for intake in the front.
The cpu is cooled by corsair h80i V2 liquid cooler with push pull fan and the radiaor at the back.

So I am really worried about these temps. Are these normal during gaming?

Also what is the max safe temperature of Cputin Tmpin5 and Tmpin3??

Thank you so much for your answers

It's your computer case, it's awful for airflow.
Basically those front fans don't work because of that front glass panel.
If you take that front panel off your temps will drop significantly.
Because you're not getting good air drawn in from the front, you're not getting good airflow over those parts of the motherboard.

Also not having an aircooler can lead to increased mobo temps, as those pull more air over the motherboard, vs a liquid cooler.
And a "downward" airflow cooler (much like the stock CPU coolers Intel and AMD provide) also help cool the mobo components.
