Stress testing failed

[Meng]

Hi all,

I've just built my rig and it plays high-end games at around 60 degrees but when I come to stress test it in OCCT it runs for around 10 seconds and stops because the temperature quickly reaches 91 which is what my TJ max is.

My rig specs are -
i7 3930k @ 4.6ghz
Asus x79 Sabertooth
Nvidia GTX Titan
Crucial RAM 16GB @ 1600mhz
XSPC RX240 - D5 - Raystorm - cooling CPU only at the moment

The system seems perfectly stable whilst gaming but fails stress tests miserably, could the problem be the thermal paste or the overclock settings? in OCCT when I run the stress test my CPU core 1/2 goes insanely high and then reaches TJ max whilst 3 is a little lower and 5 and 6 is around 30 degrees from TJ max...

Many thanks in advance

Meng

have you tried other stress test's

what vCORE voltage are you running for a 4.6 overclock?

can you verify the pump is moving coolant?
i normally don't ask, what is idle temperature?

Hi, vCORE voltage is around 1.100 with offset settings on. I can see the coolant moving and the idle temperature is around 30-35 with a 14/15 ambient.

Do I really need to do stress testing? I seem to be able to run games and render videos at a reasonable temperature. Also, I have still/mineral water running in there at the moment which I will be swapping out in a week or two, could this be another contributing factor?

Thanks,

well, it is not that stress testing is needed, but clearly you have an overheating
problem. with such low voltage and low ambient, i'd think your idle should be close
to 20°-25°. usually 15°-20° over ambient is hot.. and your overclock voltage isn't
that "heated". try stock setting and verify temps again. with such a low ambient
and loaded being high, the delta is extremely high. heck, H100 AIO do better than
this in idle and loaded (see TTL temp vids).

since this is a new build, have you been able to get all of the bubbles out?
got a picture or two of the build?

try reseating the block. And just a stupid question lol as others have done it before. Did ya remove the plastic protection film from the bottom of the block??

I will put it to stock and find out how it performs at that level later on, a bit busy at the moment will post a picture later on as well.

As for the air bubbles, they seem to have gone, I shorted the MB plug and kept turning it on and off and that seemed to have gotten a lot of it out, I have seen an air bubble in a while although sometimes there is a random line of it running through the loop although that is rare and only for half a second.

I think I will have to resit it and apply the paste again, it may not have spread properly. I did remove the plastic protection film from the bottom yes, I made sure of that would have been disastrous otherwise ^^

Thanks guys, will post more info this evening.

Picture of the rig -

Short OCCT run and hitting bad temperatures -

It seems like 3rd to 6th core is running a lot better, maybe the thermal paste didn't spread or the screw isn't tight enough on one of the sides to conduct enough heat?

FIXED: I had a moment of clarity and decided to take my CPU block out, I discovered that there plates were barely conducting via the thermal paste as the block did not even have the paste spread evenly on it. I then thought this mounting method looks very odd and decided to revisit the menu also.

I looked and found that I had installed it the wrong way round with the springs under the plate on my LGA 2011 sitting. I am now able to run OCCT stress test on the CPU without any problems it seems, I am 17 minutes in and the temperature hasn't reached over 76 degrees on any cores yet.

Anyway to improve the temperatures? or is 76 after 16 minutes ok? I am running low-mid volts on my overclock @ 4.6

Thanks,

Meng

1.344V isnt exactly low-mids voltage...

 

[Reloaded2]

I think the proble lies with the voltage 1.344v isn't classed as low

I mean in terms of a 4.8ghz overclock, it isn't that high vs someone who might need 1.4v to get to that overclock. I am getting 32 ish on gaming and 50-60 whilst gaming and recording.

Need to get a room temp to verify delta...

Have you tried blowing on it?
