i7-4770k Getting Stupidly Hot (with pics)

purplemesa · Sep 12, 2017

Hello all,

Recently, while playing games my computer has completely shutdown (no bluescreen, just a complete power loss) twice over the course of about a week. After the 2nd time, I noticed a peculiar smell coming from the PSU and immediately replaced it, as well as air-dusted the entire case thoroughly.

I haven't had another auto-shutdown incident (yet) since the PSU upgrade, but I did begin to monitor my temps more closely and I noticed that my CPU cores have gotten especially hot. Usually this is while gaming, but they can briefly spike into the upper 80's or even low 90's (Celsius) for unknown reasons while doing nothing especially straining. I'll let the pictures speak for themselves, I've used 3 programs to monitor the temperatures, and they were taken immediately following a 1 hour gaming session:

Specs (This computer is slightly over 3 years old):

i7-4770k @ 3.5 - 4.2GHz (Manufacturer overclocked ~10%)
EVGA "Superclocked" GTX 780 (Mild factory overclock)
Corsair H60 cooling loop, w/ 1 Pull Fan and 1 Push fan on each side of the radiator (case has two more fans as well)
Corsair TX850M 850W 80 Plus Gold Power Supply (New)
Gigabyte G1.Sniper 5 Motherboard
2 x 4GB DDR3-2133 G.Skill Ripjaws X

CPU Temps / Voltages:

GPU Stats (also kind of toasty?): https://imgur.com/AwNXKBX

Possibly Relevant BIOS Settings (forgive phone pictures): https://imgur.com/9KmgL8j

What can anyone make of this? Clearly these temps are getting out of control. Even in BIOS, the CPU was hitting up to 80C

I'm considering reducing the clock speed and/or voltage of the CPU if necessary. I've seen on a sticky here that the "auto" voltage settings are not recommended for an overclock (I didn't personally set up any of that) Does anyone have a more experienced recommendation on what I should try here to get my temps under control?

I appreciate all input.

Have you tried reapplying thermal past to the CPU?

purplemesa · Sep 12, 2017

No, I consider myself a novice on hardware and I've not removed the water cooler interface with the CPU before.

Novice questions: Are coolers like the H60 meant to be combined with thermal compound?

Will lifting the cooler interface damage any compound that is already present?

How difficult / "dangerous" would a paste removal and reapplication be for a beginner on a scale of 1-10? (I'd prefer to explore simpler solutions if they exist)

I have some 3-4 year old "Tuniq TX-2" thermal compound, still sealed. Does the age matter in any way if I applied it now?

purplemesa :

If I'm not mistaken every cpu cooler to this date requires thermal compound to ensure heat connections between the cpu and heatsink are at their best. If you lift the cooler off the CPU it doesnt damage anything but releases it from the cpu leaving thermal compound on both the cpu and the heatsink (I normally remove using a paper towel and some rubbing alcohol.) and you can reapply with the method used in this article/tutorial http://www.techadvisor.co.uk/how-to/desktop-pc/how-to-apply-thermal-paste-cpu-3636146/

(It doesnt take much skill to reapply thermal past BUT MAKE SURE YOU DONT ADD TOO MUCH (some people have had thermal compound fall on their cpu pins from adding too much, rendering them useless.) as long as you dont add ALOT then your fine

EDIT: oh and yes old compounds should be fine to use as long as they are still in liquid form inside the tube.

Noted, thank you for the advice, but what is your opinion on tweaking the voltage? Does ~1.308V seem high for Haswell? Should I change the "auto" setting in the BIOS?

purplemesa · Sep 12, 2017

(bump) Any knowledgeable opinions about the voltage tweaking idea?

Zmanrocks · Sep 12, 2017

purplemesa :

If Im not mistaken anything above 1.5/1.6 is not recommended and will damage your CPU greatly. 1.3v should be fine

EDIT: as long as on stress tests dont exceed 80c

Zerk2012 · Sep 12, 2017

1.3 is high for that my 4790k overclocked to 4.6 is at 1.22 volts.
It sounds more like to me your pump is going out on the cooler.
I would first lower the voltage then replace the cooler if that don't work.
You should not need new paste after just 3 years.

Zmanrocks · Sep 12, 2017

Zerk2012 :

Ditto, I guess 1.3v would add tons of heat and lower the cpu's lifetime, I run my 4690k at like 1.2v at 4.3ghz (If I remember correctly)

purplemesa · Sep 12, 2017

@Zerk2012 That sounds like a solid plan. What kind of a temperature decrease could I realistically expect if I reduced the voltage and/or clock speed if necessary? Currently the motherboard is set to Auto voltage, which I read in a sticky here that that's not ideal.

Zmanrocks · Sep 12, 2017

purplemesa :

Games should run at most 60-70c but shouldnt exceed 70c (the temps will be determined depending on the game) So you should see a very exponential decrease in temperatures with a new AIO Cooler (if that is the problem) which it most likely is.
Idle temps should normally be 40-50c

Edit: this is normally seen with an overclock

Zerk2012 · Sep 12, 2017

I run OCCT to stress test a CPU with mine the highest temp I have got is about 78C that is pushing the CPU 100%. Of corse my cooler is much better than yours.
The bad thing about buying it with a 10% OC their always going to add more voltage than required to ensure a stable overclock.
