i7 4770k temperature.

Xoriie · Jan 19, 2016

Hello, I have an i7 4770k cpu overclocked to 4.0ghz and my average temperature is about 75 degrees C. Is that normal with water cooling?

Update: I was playing Star Wars battlefront and got temperatures of an average 85 degrees with approx 95 % load, I know 90 degrees or higher can shorten the lifespan. Any tips as to why this happens on a water cooled cpu?

What vcore you running?
What cooler you using?
Those are high temps for a very mild O/C.
When you exit the game do your temps drop rapidly or do they gradually drop ?

To maximize the CPU's lifespan, Intel recommends that you don't go above 74.02 Celcius. You are pretty close to that magical temperature where your CPU just melts (TJ MAX is 98C). It's not normal on a watercooled CPU. I would recommend that you remove the OC for now and watch the temperature. If you used your motherboard's automatic OC, it probably is using much too high voltage for it's needs. For example, my Z87-Plus was OC'ing to 4,3Ghz at 1.325V, which is way too high. I managed to reach 4.5Ghz at 1.224V, and it runs perfectly stable. More volts = More heat = Trouble.

This shouldn't happen on any CPUs, but I would suggest reapplying thermal paste and making sure your cooler actually work. If the pump isn't on, then seeing very high temperatures is to be expected and most pumps are very silent, so you wouldn't necessarily notice a difference between on and off.

It is worth noting that buying a 4770k doesn't guarantee anything in terms of OC. If you unlucky, it is possible that any overclock will generate intense heat, because the processor can't take it. Intel guarantees that your I7 will run stable at 3.5Ghz/3.9Ghz Turbo. OC'ing is trying to find your CPU's actual limit, which could be 5.0Ghz if you're lucky and have good cooling, but it could also be 3.9Ghz if you aren't. Silicium's a B***h xD

My cooler is a corsair H90
And my vcore is 1.2v
And the temp drops rapidly after exiting a game.

It's wierd, cause earlier i've had it overclocked to 4.34 Ghz and the temp was below 60, now it just keeps getting warmer. My vcore is no more than 1.2 either. So I'm not sure. xD

Has anything changed with the PC added anything changed fan profile etc
Do you hear a water trickling noise ?
When you have high temps try applying a little pressure to the CPU cooler block and see if temps change.

Xoriie · Jan 24, 2016

Sav4 :

Tried to apply pressure to coolerblock and nothing changed.
Don't hear any noise from the water cooling.
And i've only added NZXT Hue+ lighting to my pc lately.

Sav4 · Jan 25, 2016

Are you using their software?
If so isn't there fan control in the software?

serioussamik17 · Jan 25, 2016

From what I see you got >60 C before with a higher overclock and you didn't change the voltage. Adding the Hue+ should not be the problem.
Assuming it was the same cooling setup, there might be some issues with the arctic paste. Did you check if the thermal paste that came with the H90 is intact? If not, you can apply another layer.

Sav4 · Jan 25, 2016

The reason I asked about the software is that it sometimes sets its own fan profiles which override the bios setting. If it has the cooler may have them set lower than he had before affecting temps.
He has also said his temps drop rapidly after exiting the game which would indicate good contact .

When you changed your OC did you go from fixed voltage to adaptive?
What else was changed ?

Xoriie · Jan 25, 2016

Sav4 :

I haven't changed anything in the voltage after the previous overclock. Haven't changed anything else either.
I ran a stress test which ended up with a temp of 96 degrees! That's way too high.
Also, It's no fan control for the software I'm using.

Xoriie · Jan 25, 2016

serioussamik17 :

Wouldn't it be better to clean it off and use a different kind of paste?
I've heard the arctic paste is not as good as other brands.

Sav4 · Jan 25, 2016

That's wierd then could you take a screenshot of hwinfo under load with voltages,fan speeds ect ?
You could do a reseat I doubt it will drop it 30deg .

serioussamik17 · Jan 26, 2016

Xoriie :

Yes, absolutely. It would be better to completely remove the earlier paste and apply a newer one, preferably from Antec or Arctic.

Here's the hwinfo under load, the fan speeds displayed at the right is for my gpu not my cpu.
My cpu fan was running at 2500rpm.

Sav4 · Feb 1, 2016

That all looks good can you put it back to stock and report temps please as the overclock is .1 ghz over turbo boost shouldn't be so high . That might narrow it down to a cooler issue.

Sav4 · Feb 1, 2016

Also what's your ambient temperature?

Xoriie · Feb 2, 2016

Sav4 :

18 degrees.

Sav4 · Feb 4, 2016

Have you put it back to stock ?
Temps at stock?

Xoriie · Feb 9, 2016

Sav4 :

The exact same.

HardwareExtreme · Feb 9, 2016

The i7 4770K is a hot running chip. Are you sure you don'y have a large amount of processes running in the background?

Sav4 · Feb 9, 2016

If you have the stock Intel cooler install that and see if temps drop at stock . I'm suspecting a cooler fault .
All case fans are definitely running?

Sav4 · Feb 9, 2016

Make sure you go into bios and load default values to , so it removes anything that may have been changed

i7 4770k temperature.
