4770k is HOT

culzone · May 24, 2016

Any other 4770k owners here? what are your temps ?
1.2v @ 4.2 ghz im at 85C during 100% load.. if I go 1.25v im getting 90C+
Also using a h60 liquid cooler

Gaming load Im about the same as you

Sergeant_Sneaky · May 24, 2016

What are you using to stress test at 100% load?

culzone · May 24, 2016

Sergeant_Sneaky :

Tried with Gigabyte extreme tuning utility and CPU-Z also tried prime95 but I've heard bad things about the voltage there so I removed it

culzone :

Okay, it's possible that you got a hot chip, the 4770s are kind of known for being warm. Have you checked that your pump is working correctly at the right speed?

yep, changed the speed to full speed in bios and im using speedfan to check the speed

If you can, try and bring down the voltage a bit. That's the easiest way to reduce heat production. Maybe you can remain stable at 1.195V or 1.19V even a bit could make a noticable difference.

For how long do you recommend me to be running stress test at each voltage before going even lower?

Per the Guide:

"Test:

Run Prime95 v26.6 Small FFT's for 10 minutes, then use your thermometer to measure Ambient. Use Core Temp to measure your Core temperatures.

Results:

If reported Core temperatures exceed 80C, you should reduce Vcore and clock speed and / or improve cooling. Core temperatures in the mid 70's are safe.

Note: Early Legacy 65 nanometer Core 2 variants with stepping revision B2 and B3 have lower TjMax specifications than other processors. Use CPU-Z to view your stepping revision. For these variants, Core temperatures in the mid 60's are safe.

Intel’s specification for Digital Thermal Sensor (DTS) accuracy is +/- 5C. This means deviations between the highest and lowest Cores may be 10C, so "Average" Core temperature is often more realistic.

On processors with more than 2 Cores, the inner Cores run warmer because they’re insulated by the outer Cores. Here’s the physical layout in 2nd, 3rd and 4th Generation Quad Core processors, and an example of how it typically affects Core temperatures:

IGPU = Not in use (PCIE graphics card in use)
Core #0 = 75C (insulated by IGPU and Core #1)
Core #1 = 78C (insulated by Core #0 and #2)
Core #2 = 76C (insulated by Core #1 and #3)
Core #3 = 71C (insulated by Core #2 only)

Core Average = 75C.

Note: When viewing your temperatures in Core Temp, values which reach 81C or higher will change from black to amber, which indicates caution.

Normalize your results to Standard Ambient and record the values for future reference."

at 4.2ghz 1.2v im jumping between 72 and 83C

culzone :

If you ran Small FFT's which is a steady-state 100% workload, then each of your Core temperatures should also be steady. If you instead ran Blend, which is the default test and is a cyclic workload for testing memory, then your temperatures will fluctuate.

(1) Did you run Prime95 Version 26.6 Small FFT's?

(2) What is your Ambient temperature?

culzone · May 24, 2016

CompuTronix :

Prime95 version 26.6
Core0 79C
Core1 79C
Core2 77C
Core3 70C
ambient temp 23C

WildCard999 · May 24, 2016

culzone, what is you package temp (HWmonitor) after 10 mins of Prime95 V 26.6? Make sure that your running the Small FFT's test, by default it looks like the Blend test is selected. Go to Prime95 > Options > Torture Test > Select Small FFT's and click Ok.

CompuTronix · May 24, 2016

Package temperature is simply the hottest core. 79C is marginally hot at 23C ambient, which leaves no headroom to operate in higher ambient temperatures.

Cable management?
Case fans?
Computer location / ventilation?

H60 is on par with mid-range air. Upgrade to better cooling perhaps?

CompuTronix :

I have good cable management inside a NZXT h440 case, also got 7 case fans
Location top floor of the house so can get much hotter in there
Might get a better cooler been thinking of it
