Safe 4790k Temps while overclocking?

[Vengeance_K1ng]

So, i have been browsing the Fourm "Toms Hardware". There is a guy called computronics, and he wrote a very detailed guide to intel Core i temperatures. He explained that " Core i 2nd through 6th Generation CPU's have AVX (Advanced Vector Extension) instruction sets. Recent versions of Prime95 such as 28.7 run AVX code on the Floating Point Unit (FPU) math coprocessor, which produces unrealistically high temperatures. The FPU test in the utility AIDA64 shows similar results". So, i am stressing with prime95, Version 26.6 small FFT and i am running an OC of, 4.5 Ghz with 1.240 Voltage. My temps are in the mid 70's . He pointed out that Temperatures in the mid 70's are safe, but when you hit 80C, its best to dial down. Do you agree that Temperatures in the mid 70's are safe for Haswell?

Yes.

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

keep in mind that people use aida 64 more than Prime 95. Prime95 Small FFT's is the standard for CPU thermal testing, because it's a steady-state 100% workload. This is the test that Real Temp uses to test sensors. Version 26.6 is well suited to all Core i and Core 2 variants.

Not 100% right. While AVX is supported, there's also support for FMA3 ever since 28.3. In other words, 4th gen and above get another huge speedup... and obviously, temps go up as well. If you want to properly evaluate your temperatures, you should use one these latest version, as they can actually push you to your limits.

 

As far as being safe, up until high 70s and you are good. You can top low 80s, but if you ever hit 85ºc or more, then you should dial voltage down.

Nope. Take what you read on Toms Hardware with a grain of salt. Most of the things you read on there may sound legit, but are not

So are my temps normal for an x61? because i was thinking of down sizing to an x41

Normal? Yeah. But I wouldn't downsize, seeing as you aren't using the full potential of your chip yet already getting close to thermal limits.

So wait, the temps are a bit high right?

Define "high".

Man there sure are a lot of threads about your temps.

Well, i mean i am running stock and im getting close to 70C while stressing. I was thinking about de lidding

Sorry dude, I just get so worked up about it.

4.5ghz with 1.24v isn't stock...

No, i am running sotck everything in bios.

No sweat bud.  It's just funny that I have a 50/50 chance of opening a high temp thread and seeing you in there. 

 

Your temps are fine. 

 

Tell us more about how it does under normal operating conditions?

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.

Fixed mode to what voltage for stock?

I think Ul find that's stock voltage tho

Before that, i have money to delid. i can send it to silicon lottery, they will delid for me. will that decrease temps?

[jjohnthedon1]

Use Intell extream tuning utility to stress

it gives the most acurate reall life temps u will see with CPU at 100 percent load

I think the more important question is do you need to decrease your temps?  Sure, you can send it off and possibly reduce temps a few degrees, but it won't be as much as the pre Devil's Canyon chips.  Bottom line is that your processor temps and current cooling arrangements are fine and well within margins of safety.  

 

Sit back and enjoy that computer a little and stop testing it so much.

I don't know? Do you want to push your clocks further? If so, get the highest voltage you can up until you hit 80. If you intend to leave it at 4.5ghz, then as low as you can, without instability.

Yes... but you'll need superb thermal paste as well, else half of the point of delidding goes away.

Thanks man, so can i atleast run prime 95 version 26.6 all night to get a baseline max temp? and btw, why do other people have better temps than me on their x61, is mine not working right?

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