i7 4770k hot as hell

Toft · Mar 13, 2016

I got a Intel i7 4770k no overclocking done (That i know of)
And it seems to idle @ 30-31c but if put under load the CPU temp will rise to 81c..

We tested my mates i5 which took the same stress test and he's max temp was 65c while mine was 81c (I know that there might be some diff since it's 1 diff CPUs) But the weird part is he has air cooler while i got a asetek water cooler..

I'm really scared that my CPU might overheat, since 81c is ALOT with water cooler (atleast i think it's)

Screenshot of me testing it (Notice I'm only taking the test on "Normal")

Fan setup while doing the tests, also this time i was monitoring the temp with CoreTemp.

I already got a asetek 510LC water cooler.
And from what i can tell from Core Temp it's a haswell CPU

if you mounted your radiator on the exhaust, and you have a hot GPU or other components, it will cause the temps top be different if you mounted on an intake, or its just a thermal paste or copper water block conduction problem. clean the paste and remove anything that might be obstructing the conduction. and then reapply paste and check the cooler is seated properly

The fan on the radiator is an intake not exhaust.

Is there anyway to like control my water cooling? (My mate is using MSI command center to control this air fans)

The 4770K is a very hot CPU. Intel improved the TIM for Haswell Refresh and dropped temperatures by about 10C at the top end. Idle is OK, so the cooler is probably working fin. What is the air temperature in the room?

DonkeyOatie · Mar 13, 2016

We know it's a Haswell CPU. Haswell CPUs, like the 4770K ran very hot, so they upgraded the TIM for the Haswell Refresh (i7 4790K) and dropped the temperatures by about 10C as I mentioned above.

All of this means that your temperatures are in the 'normal' range for that chip.

DonkeyOatie :

So you're telling me that even with a asetek 510LC watercooler it's normal to hit 83c on CPU cores with a "normal stress test" because im afriad to test it with a high stress test then.

Just what is the safe temp for my CPU when under heavy load? :-S

Found this in another thread, he has the same CPU and have done alot of overclocking yet his temp is 10-20c lower then mine :-(

"Under heavy load with the i7 4770K at 4.6 GHz it hovers around 60 - 70 C and cools off to 25 -30 C as soon as the load is removed."

DonkeyOatie · Mar 14, 2016

In your original post, you merely said 'stress test', which I assumed was something like Prime95 26.6 (or even higher), OCCT, Aida64, or ASUS Realbench. 81C is a temperature in the normal range for the i7 4770K for those circumstances.

The Asetek 510LC is about the same as a Corsair H50. It's a very entry level water cooler and is actually inferior in cooling to very many air coolers. Its benefits come from space saving and ease of transportation.

A stress test should exceed any normal heavy load and I'd expect something in the low 70s with your system under normal heavy load.

What stress test are you running?
The other system you are comparing with (overclocking 4770K) what CPU cooler are they using, and to want speed and voltage?

Read this thread. http://www.tomshardware.com/forum/id-1808604/intel-temperature-guide.html

You will notice that as you hive us more detailed and specific information our response can be more nuanced.

I'm running the IntelBurnTestV2 (http://www.techspot.com/downloads/4965-intelburntest.html)

Also I'm think about using a "Noctua NH-D15" to cool my CPU instead of the Asetek 510LC.
I got a mate which uses this and he has no problems at all, even while overclocking.

DonkeyOatie · Mar 15, 2016

That is a good stress test.

I overclock my i7 4790K on a Noctua D15S and even overclocked to 4.8Ghz, it the temperatures barely rise over 80C when running Prime95 v26.6, and are in the 50s to 60C under normal 24/7 heavy use at 4.6Ghz.

There are likely multiple things in play here.

1. The i7 4770K is a hot chip and runs as much as 10 degrees hotter than the i7 4790K
2. The ASetek 510LC is a low end watercooler and I would recommend something better.
3. ????? There is still the possibility of a poor paste application, waterblock mounting problem, or radiator issue with your cooler that further reduces efficiency.
4. ????? There is the possibility of unintentional over-volting by your motherboard. (I see temperature information above, but I'd be interested to see how the VCORE behaves under stress)

DonkeyOatie that alot of fine words very fast :'D
I'm not really a hardware kinda guy, but my mate ran over my PC (Just a quicky) and it said that the paste is fine, the cooler is sitting where it's supose to, and we checked and corrected the airflow (Downed the C with like -3).

My motherboard is a MSI Z87-G45 GAMING (MS-7821), and i got no clue if it's over-volting anything I've done no OC'ing and again i got no clue what VCORE is :s

Might aswell just post my whole setup:
OS: Windows 10 Home 64-bit
Motherboard: MSI Z87-G45 GAMING (MS-7821)
Graphic card: x2 2047MB NVIDIA GeForce GTX 760 (MSI)
Storage: 111GB Samsung SSD 840 EVO 120GB (SSD) & 931GB Seagate ST1000DM003-1CH162 (SATA)'
RAM: 16,0GB Dual-Channel DDR3 @ 1066MHz (11-11-11-27)
CPU: Intel Core i7 4770K @ 3.50GHz, Haswell 22nm Technology

Even with a haswell 4770k you should not be getting that warm. Never use prime if you are for stress testing use aida64. Make sure in your bios you are running the lowest possible voltage you can and still be stable. This will help your temps alot! When i first unboxed my 6700k 2 weeks ago it was running upwards of 70c during stress testing. After figuring out my coltage was way to high for stock (and thats thanks to the motherboards "auto vcore" setting) i lowered it almost half a volt and now im hitting 55c under dull stress twsting. Also your liquid cooling system should have a software or something to control the pump speed. Make sure thats at 100% all the time. Between tweaking your vcore (cpu voltage) and making sure your pump is at 100% speed you should see big drops in load temps. Every time you make a vcore change make sure to run a stability or stress test to see if you're stable. Find your lowest vcore voltage and be on ypur marry way with cooler temps.

Azzazel_99 I've been searching for software to control my watercooling pump, but the only thing I've been able to to find was MSI afterburner which is for my GPUs..

azzazel_99 · Mar 15, 2016

Was it a all in one water cooler? Like you opened it out of a box andnput it in or is it a custom loop water cooling solution? Your motherboard also should have a cpu fan1 or if its newer it should even have a pump 1 plug on it

DonkeyOatie · Mar 15, 2016

You are going to have to pick between me and Azzazel_99.

I say that with your system, that's not too far off the charts.
They say that with your system, it's far too hot.

In response I say for a 6700K and even a 4790K they are right, with the 4470K I'm right.

you might need to do some more research to see what experience others have had with that chip.

Some other threads.

http://www.xbitlabs.com/articles/cpu/display/core-i7-4770k_12.html

Look at the temperatures reported, the speed of the chips, and the coolers being used.

azzazel_99 · Mar 15, 2016

Yes the 4770k run hot but you can make it run cooler by doing as i stated. Everyone should do it honestly.

Toft · Mar 15, 2016

Fuck this shit, Imma buy that air cooler and then lower the voltage and ill have a cold ass CPU.

A bit off topic, why do i get between 120-170fps in CSGO?

I mean my setup should be able to do 250-300?

azzazel_99 · Mar 15, 2016

You just need check where you have your water pump plugged into. The motherboard can control the cpu fan1 speeds and if the motherboard has a pump plug on it you can also plug it there. The cpu fan1 or pump plug both work to control pump speed

Toft · Mar 15, 2016

azzazel_99 :

I've added the pump to CPU fan1, now all i need is to put it to 100%?

azzazel_99 · Mar 15, 2016

you should be able to set that in the bios. You should have fan controls in the motherboards bios settings. Set them ALL to full speed or 100%

azzazel_99 · Mar 15, 2016

After that try running aida64 and running the system stability test and see where you cpu temps get too. After that report back to us and you can even start fiddling with lowering the voltage "vcore" of the cpu. You can google and search what the lowest stock vcore settings people were able to get on the 4770k and depending on how good of a cpu your's is you maybe able to get lower than other people or you may not be able to get as low as other people but running the lowest stable voltage at ANY clock speed is the key to cooler temps under load. Like my chip was able to get to 1.2v but the temps were acting weird so its at 1.225 and the temps are just as low as they were at 1.2v but they are more consistent now and stable and i get no crashing.
