Safe 4790k Temps while overclocking?

There's a bunch of factors.  For starters, what's your room temp when you run these tests?

about 70F

What fans are you using and what speed are they running at during the test.  What thermal paste (not huge, but has an impact)?  Are the fans setup as intake or exhaust (not huge, but has and impact)?

2 noctua nf a14's. They only run at 1200 RPM

I am running in a pull config. both fans are 100%

When you say that other people are getting better temps, what are all the specifications of their systems and temps?  I guess what I'm trying to say is don't worry about what someone else is getting because a lot of people talk trash to make their crap sound better.  Hell, I've done that before.

Those are very nice fans, but you're not moving a lot of air through that radiator with those.  Someone you are trying to compare your temps with may be running 1800 to 2200 RPM fans.  Big difference.

Oh fuck me, so the fans could be the problem?

You are hilarious!  

 

So yeah, 1200 RPM fans are good for moderate cooling while maintaining decent noise levels, but they are far from great at aggressive cooling.  Please note that stepping up to 2000+ RPM fans is considerably noisier.  It's all in how you manage them.  I use 23 EK Vardar F4 120 ER PWM (2200 RPM) fans in my x99 rig and you can't hear the thing at all during daily use.

So the speed of the fan can make a 15-20C difference?

Then why did you say you were running at those settings in OP?

 

Also, if you are running stock bios, change voltage to Fixed mode, instead of adaptive / auto.

First things first, I like your description for you location!  

 

Secondly, what is your beef with offset and adaptive voltages?

15 to 20c difference between what?  You and the temps other people are telling you they get?

No, like if i get 3000 rpm fans, will my temps be lowered by alot?   like between 1200rpm fans and 3000rpm fans, is there a HUGE difference?

It introduces variables to the equation. Simple as that. When benchamrking / trying to diagnose things, keeping settings as constant as possible is a MUST. That's why people should always use Fixed, at the very least when trying to compare numbers or diagnose problems.

I think we are on the same sheet of music now buddy!  I've just seen you post about not using it a few times, but you never mentioned that you only meant during testing.  I was beginning to wonder.  Thanks for taking the time to clarify.

 

I never use anything other than fixed voltage when initially establishing an overclock, but once all testing is done, I use that fixed voltage to determine my offset or adaptive voltage and I let my CPU take a break from the excess.

It's not as if there was a problem in running Fixed 24/7, though... and while offset is usually the best option, Adaptive shouldn't ever be used over the other 2 if you have an overclock. Like, EVER.

Yes.  The smaller the radiator surface area you have, the larger the difference in temperature will be.  If you are only running an AIO, fan speed will impact cooling capacity more so then someone running three or four 360mm radiators.  The less surface area you have to work with, the more fan speed you need to overcome the difference.

 

Give me about 30 minutes to try to run some tests to show you the difference.

I'd push 80's. for safe temp under 100% load

remember you'll rarely if ever encounter it while gaming. and if you're hitting mid 70's on only 1.24 volts, you got dealt shit temps,

most 4790k's can push 1.35+ with safe temps on an aio 

....if at the very least decent TIM is used between the water block and CPU. In my case, it can hit 84^oC on some of its cores after a couple of hours gaming.
