[SOLVED] Is this actually normal?

[arugal102]

I'm using an i7 7700k

When I run Prime95 with 4.8 GHz I run about 90C according to "Core Temp" monitoring program, all-tho it doesn't crash at all and is stable but the temps are just a concern to look at

 

EDIT : Solved, adjusted voltage and now it's running 75C at a stable 4.8GHZ full load

[Anghammarad]

Yes, I7 7700K are little hotheads and need heavy duty cooling

 

[grimreeper132]

new 7700K are currently known to have really high temps (cause intel is doing something wrong (probably because they anit soldered etc.)) so high temps are normal, mind you if your using the stock intel cooler I would maybe suggest getting a (better) after market cooler either air or water that would probably fix it

What is your overclock and cooling solution that is a little on the high side but also prime 95 does tend to push it really hard.

I have a Kraken X41 1-radiator, just installed it yesterday and everything is mounted correctly, temps are high but the actual clock is stable and doesn't crash at all.

 

EDIT : I won't be de-lidding it because it's just a hard task and pretty risky to do.

You can try a remount to see if it improves at all but as said the 7700K does run hot but that seems a little warm for what it is. Are you pushing a lot of voltage?

I never messed up w/ any of voltage values, i'm actually using the built-in profiles in a Z270 Gigabyte motherboard.

[PCGuy_5960]

Are you running Prime95 with AVX enabled?

Don't use the auto overclock options they tend to apply too much voltage for too little overclock, while it has improved over time the best option is still to manually tweak it to find the sweet spot.

Built in profiles can be crappy, what exact values are you running for voltage and BCLK and multipliers?

[WereCat]

90°C in P95 is fine if it uses AVX

I'm going to manually overclock it, seems like a better option as suggested by the majority.

Guys, DO NOT use Prime95 on modern CPUs. It screws with the voltage and might damage the chip. Run something else like cinebench to check stress temperatures.

Only if you use AVX, which is what increases the voltage

@arugal102 Can you check your CPU's VCore with HWMonitor?

I've set my overclock to 4.6GHz for the time being, but here's it under heavy load :

Is this while running Prime95?

Yes, with those settings : https://gyazo.com/9e8bb7741263d10668cf75da411c7c40

 

Edit : getting 75C with 4.6

Yeah, it's probably because you are using 1.35V, the 7700K at 1.35V gets pretty hot if it's not delidded.  BTW, you DEFINITELY don't need 1.35V for 4.6GHz, I am pretty sure that you can do the same with just 1.25V

What's a recommended voltage value for a 4.8 GHZ?

1.3-1.35V probably. @done12many2 has binned a crap ton of them so he should be able to tell you more about this

this question is general to everyone, but i'm quoting you since it's on topic. Why doesn't everyone use intel's extreme tuning utility? I've been using it and it seems to run fine.

With a 20c ambient on a delidded 7700k cooled by a large water loop, I'm able to run RealBench stress test at 4.7 GHz with 1.16v.  Start with 1.225v for 4.8 GHz and see where you are at stability wise.  Your chip will obviously differ from mine.
