Ok now that I got everything working (was having issues with my HDDs not powering on) I thought it is time to do some stress testing on the CPU.

I ran prime95 and the temps went to around 80C and after about 15-20 mins they were close to the 100C mark (ranging from 95-100).

Is this even possible or something went wrong?

I saw on some review online, prime95 + i4770k + stock cooler was running at about 80C..

Any ideas? :confused:
 
Could indeed be case airflow/cooling, not helped by this recent weather. Add in the fact that haswell cpu's run incredibly hot to begin with. 80c on a stock cooler wouldnt surprise me at all tbh.
 
Yes, indeed. Combination of things. What caught my attention was initially going to 80c and 15-20minutes later it's 100c. That makes me think case airflow is not removing the hot exhaust and it's mixing with intake air heating the case up.
 
These are my specs

Case: Fractal Design Define R4
Motherboard: Gigabyte Z87X-D3H
Processor: Intel i7-4770
Cooler: Arctic i30
HDDs: 2x Samsung F3s
SSD: Crucial M4 256GB
GPU: XFX GTX 260
PSU: Corsair TX750W (rev1.0)

I got 2 fans in the front of the case and 1 in the back. I did my best in cable management. Very strange temps.
 
Okay, what is case fan speed set at? Try running them on high speed. Stock case fans are not great. Especially with filter and grill in front of them and HDD cage behind.

They are running at 850+/-

The CPU fan is at max 1350+/-

The case fans are these: CLICK

I am running another test right now, and it just hit the 100C mark again after 16 minutes.
 
I will max them out later on (got something else to do right now) and run another prime95.

By the way, is it possible that I got a defective CPU? If I remember correctly, back in April i had an i7-3770 with the same cooler and on prime95 tests it was hitting 60C max.
 
So I maxed them out (at around 1000RPM) and ran prime95. I thought it was better, but after 18 mins it hit the 100C mark again.

One thing i should mention is that this is the "blend" test. If I start "small ffts" test then it goes straight to 100C mark in a metter of seconds.

This doesn't make sense. This cannot be normal, even in this weather. :confused:

I am looking at some temp stats for the K version and 4.1 overclock and the Hyper 212 EVO keeps it at 85C and my i30 should be near the same performance as that cooler.

I guess I will leave it off tonight, test again tomorrow and see what happens. Will try to clean it and put new paste to see what happens and then if it is still hitting the 100C, I will have no options left.

So probably not a case cooling issue
Sorry, didn't realize you were running blend test.
Weather is contributing but something isn't right.
Every chip is different when overclocked but yes, 85c is about right. But with this weather you can add 5-10c to that.
Can back the OC down a bit.
 
My one is not overclocked. I was referring to some temp stats i saw online on an overclocked K version. What I meant to say is that my not overclocked one is running hotter than an overclocked one with a similar cooler.

Anyway, I just got up and did a prime95 test (small FFTs) straight after boot and it started at 90C and 100C in 4 mins.

I will change the paste and see what happens, but I have no faith :D

Back to my question from above, could it be a defective chip?
 
A defective cpu is a possibility, though it is quite rare. But theres every chance that the cpu die hasnt been pasted very well. Haswell and ivybridge use rubbish thermal paste between the die and the heatspreader, unlike other intel chips that are soldered. Try re pasting the cpu first using a small rice grain sized blob. Make sure to thoroughly clean the cpu surface and cooler base before applying the new paste.
 
This happens all the time now with Haswell if you run prime or ibt. Also most boards seem to overvolt the nuts off the cpu if its set to auto. I have had 4770K at 4.3Ghz hit close to 100Degrees using prime or ibt and that's with a H80i and 1.2v with low llc. People recommend not to use those programs to test stability but to use something like Aida64.
 
Same stuff with new paste and prime95.

Well. This is interesting. Been running Aida64 stress test for 40 mins and the temps are around 70-80C.

Then I ran IntelBurn Test, it started nicely at around 65C and after 3-4 mins it went to the 100C mark.

Look at this guy's CPU:

Hyper 212 Evo with 2 fans push/pull, Arctic Silver paste I7 4770k, G1 Sniper 5. Ambient room temp: 23C

You can see why I am concerned with my one. Running at stock getting to the 100C mark makes me paranoid.
 
Ok I just run another ibt and had the CPU-Z next to it.

As I said earlier it starts at about 65C and then jumps to the 100C mark.

While at the 60C mark, the core voltage is at 1.135V. Then suddenly it jumps to 1.217+/-V nad the temps jump to near 100C. :o

I guess this is the cause.

Now, is there a way to make sure it doesn't go over X volts (like a maximum, not a fixed voltage)?

Also, I assume this is caused by the motherboard. What should I do?
 
Like I said before it does this when running IBT or Prime. It may be something do with 3D Transistors, AVX2, Thermal Compound Etc Etc but no one knows 100%. If you run Aida64 then the temps are a lot lower and the cpu doesn't throttle. Some would say that its because it doesn't test the full complement of the CPU to the max but others inc motherboard manufacturers recommend it.
 
I got the replacement CPU yesterday and fit it in.

Prime95 and IBT 79-89C for all cores. Then my friend brought up the weather and I thought f*ck, might be because the temps have dropped and I quickly installed the old one again but it hit 100C mark again so I was relived.

The temps are still quite high, but at least they are not hitting 100C :D

I should be fine with these temps now, right?
