Hi guys,

Just wanted a check on how well the cooling situation is.

Currently getting 72 degrees peak on bf1 using a nh-d15 on an ASUS maximus VIII ranger.

Currently running stock but possibly want to overclock in the future when I know my around my computer a bit more.

Cheers.

Pretty much as far as prime95 is concerned. Prime95 like all stress testing places an unrealistic load on your cpu, the thinking is that if you're passing stress test the system is definitely stable for everyday use.

72 degrees peak on bf1 is fine so you are good as far as gaming goes.

When you begin overclocking you'll want to test every change as you're OC goes up, the stress test are a more efficient way than say gaming as they are likely to expose instability faster. You also will avoid the possibility of corrupting your games/programs by using stress test should there be any...

Think you're fine, you should run some stress testing while at stock and make notes as a baseline. This will be valuable when you begin OC.

Keep close eye on temps! You don't really want to see anything over 80ish.

Prime95 ver 26.6 small fft for thermal testing, blend for overall stability.

ROG Realbench, overall system stability .

Thanks for the reply. I will proceed with this stress testing but before I do, could you possibly give me some ballpark figure that the temps should be in for this setup if you can?

Hard to say, to many variables.

Case and fans, fan position and size, ambient temps, video card/cooler type ect.

7700k runs hot, as a guess i suspect that Prime95 small fft will push you over 80c. Rog realbench 70's.

You also will avoid the possibility of corrupting your games/programs by using stress test should there be any instability with your OC.

I suggested running prime95 at stock so you could get a baseline to work with as you go forward with OC. Not that it's a bad idea to stress at stock to eliminate any manufacturer's defects, to test current settings and cooling.

The 80c number is for CPU longevity. It is generally accepted that running over this is not ideal.

If stress testing at stock runs CPU temps to high, there are many things that can be done to fix this. Adjust voltages, correct case airflow, correct heat sink mounting and at the more extreme end deliding CPU.

Here is a good OC guide that I used for my system, http://www.overclock.net/t/1621347/kaby-lake-overclocking-guide-with-statistics

Thanks for your comments, one last thing I just want to confirm is that are most quotes of temperature done on highest core temp and not CPU average across all cores, I assume it is the former?

Just did a 15min run of prime 95 v26.6 small fft. This at stock speeds, it peaked each core at 70 degrees and almost entirely stayed at 68 degrees throughout. No throttling or ramping down for clock speed. I assume this is ok for stock and no manufacturer defects?

Yep, good to go! As far as temps.

Might want to give blend option a few hours. Run realbench also.

Take notes, for future overclocking.

Is there a reason why prime 95 would yield lower temps than bf1? I imagine it could be because the fans don't have time to ramp up when temperature rapidly fluctuates as opposed to the constant level of prime 95. Any ideas yourself?

When you say stock, is this with or without multicore enhancement?

What speed is shown while running Prime95 on all cores?

What gpu do you have?

Considering weak case fans from earlier conversation.

I'm going to go out on a limb here and say that since we are talking about a couple of degrees C, that case temps while gaming are hotter and that is resulting in higher cpu temps.

The case fans were really going at high rpm during prime 95, in bf1 not so much. I could adjust the fan curve to be more aggressive, other than that, just using better case fans as you suggested may be the answer if I want better temps.
