I have my 7700k overclocked at 4.5ghz and i have the kraken 52 cooler my temperatures are at 30-34c at 5% load. Is this the norm?

HWMonitor.txt

Idle temps are sorta useless. What matters is the temperature under load.

 

Put some Prime95 goodness and report your temps back.

I recommend RealBench instead.

I let prime95 run on blend setting for 3 hours and the peak was 99c

Yup, then you have a problem, voltages are out of control.

 

Are you using Auto, or did you put it on a set ammount? If so, which value did you pick?

Oh, that explains it. NEVER let voltages on auto. Set it to manual; for a 7700k, 1.25v should do it. If it doesn't, I suppose you can increase the voltage until it does. Or even just straight up ignore that and start overclockin from scratch. But at any rate, 1.25v would be a nice place to start.

When I had a stock cooler my FX6300 didn't reach that high at 4.2. Something is wrong...

stupid question but did you peal of the plastic at the bottom of the water block when installing it?

Those aren't comparable in the slightest. For starters, the FX reads temperatures differently than Intel; Intel reads the temperature closer to the core (therefore reads higher temps), whereas the FX reads them further away (aka reads at a cooler part). Next, the 6300 is a 3 core CPU, with the 7700k being a quad core. And last, the AVX implementation -which is what causes P95 to be hot- on the FX was so garbage that the program doesn't even use it, it opts for a cooler instruction set instead.

 

Nothing is wrong, that behaviour is exactly what I'd expect from Auto voltages.

Could it be the cooler not seating correctly or not enough thermal paste? I used arctic 5 pea size.

Could be bad seating, yes. And while little thermal paste is possible, I find it unlikely; if in doubt, just add a little more, there's no problem in that.

The FX6300 is 6 core not 3, and the temperature sensor on the FX was a digital sensor that read better the closer it got to max temp witch was 60c or there abouts in its own scale, and software wouldn't see the sensor or its scale. Considering its old architecture with a BAD cooler vs the exact opposite I'd say it's quite fair to say that the one with the theoretical advantage has a problem, it may be software, hardware (considering is brand new this one is unlikely but still possible) or the plastic between the CPU and cooler was not removed and that can cause some serious heat I know it did when I forgot to do that with my 212 evo.

It's a triple core with some doubled parts than can make it act as a hexa / triple core, depending on the load. On the case of P95, which heavily uses the FPU, the 6300 is a triple core, as it only has 3 of them.

?

 

Teh fuc, man... what does that have to do with anything? I never said that the sensor was good / bad, I just said it was placed differently and read a different thing.

I have no idea on what are you talking about... no joke, I really don't understand what are your trying to say here.

True, that would cause serious heat. And I'm not saying that it's impossible, but I highly doubt that's root of the problem, given what OP has told us.

Ya wow i screwed that one up bad. Forget i said that? I don’t even know what i was trying so say now that i’m rereading it a bit later... very sorry that you had to read that and had to try to comprehend that garbage.

What i was inferring is that the FX was using an inadequate cooler it is also inefficient and hot, whilst the 7700K is watercooled and much more efficient, theoretically it should be cooler, but it’s not for whatever reason.

 

 

overall my previous post was very bad and poorly thought through, a gain sorry for that, i hope this one fixes some of my vagueness.
