processor overheat

[komyali]

I am going on vacation, and want to leave my i7 3930k (noctua cooler NH-D14 se2011) render for 15 days is that ok? It is not overclocked but I am planning that to do more than a year... I will leave friend to control it. What temperatures are ok for it and what is the best way to controle temperature, programs? If it overheat, stop rendering leave it couple of hours and then render again?

If I overclock it, is there some limit for temperatures?

Its not OCed? Yet?

So, you are planing to OC the cpu and than leave it? Wrong way....if you had OCed CPU for month or smilar, you should know how it acts OCed.

In this way, you do not know it, yet, and you are leaving for 15 days?

...

If it overheat, it will freeze/ restart, so no restarting the render...

...

Just click render and go to Makarska! No OC...why should you carry about OCing while you are on the seaside?!?! Its not worh of it!

Also, please, check this, it is simple, like a piece of cake

heheh teamviewer I have it on both computers, and I will use it but I need friend If something go very bad No its not overclocked yet... I have that on my mind all year but I dont have time to do it... Now I am doing something very important and after that vacation so maybe for a month or two I will be free to experiment and do OC.

But what about temperatures of CPU and what program to use for details about computer temperature and what is tolerable for CPU? Is there any

benchmark about that?

p.s. Ne idem u Makarsku poceli su peglati dalmatinci nabili cijene bez potrebe, Turska zakon

You can probably overclock it and not worry, but I would not in this case...takes some time and trial/error to do a decent overclock with low temps on air. You don't want to leave anything "half-tested" if you are talking about a 15D long job (or even smaller/shorter than that).

 

It can run stock under a ND14 "forever", so leave it do whatever needs to be done, and clock it after you come back from your vacation (if ever).

 

PPl like their CPUs to run as cool as possible. Rule of thumb for most is 80oC, others say 85oC.

Intel has set thermal throttling @ 100oC, and I would say if you are not close to that, you are darn safe!

 

CPUs are not "unstable" due to high temps, but rather lower than needed Vcore.

Raising Vcore and/or clocks raises generated heat = raises temperature unless you have very good cooling. Very good cooling is the only way to really damage the CPU in prolonged stress periods, as you can overclock it a lot, increase the voltage a lot - bypassing relevant safeties and wearing it down. Heat doesn't wear the chip down, voltage/current does, and while you cannot force it not to shut-down / throttle down when overheated, you can do so for Vcore.

Probably aint gonna happen with air-cooling (the CPU will overheat within seconds and throttle/shutdown/crash if you over-do it), but highly probable with very good open loop water, TEC, phase change etc coolers.

 

Your ND14 will probably break 80oC easily if you try to do more than 4.4-4.5GHz, possibly even 85oC or more with stress benchmarks/tests.

 

People run stress tests like Prime95 on all cores or intel burn test (LinX) to test stability and maximum temperature the system can handle. Rendering, gaming, folding and other real-life tasks - even those that appear to be using 100% of the CPU resources, rarely reach the same temperatures as Prime or LinX, thus CPUs that might break that 80-85 threshold, might be running cooler in real life.

3930К> 4-4.2 Ghz > 100% safe side, no worry

..........4.2-4.4Ghz> 80% safe

..........4.5+GHz...not so safe...

What are your PSU and motherboard?

No need to use some fancy bench tools.

Just do like this:

1. Make it 3.8GHz, and leave it for few days, just work as you did before.

2. Next day, make it 4.2, and finally 4.4Ghz

if notice restarting or freezing, just make it lower, to the previous value.

This is long way, but most the most safe, to make your mobos and PSU to adopt new condition.

...

Personally, I should not use any stress/ bench tools, as they stress CPU/PSU, more times than 3dsmax/vray will ever do!

Prijatno brchkanje!!!!

I am waiting for you, and this is what I want to hear But if something bad happen, I have skills, I will find you, and I will kill you :DDD SKILS

I thnik it is 750 W I need to check it again, I will go to 4.5 or 4.4 But first I need to do research.

What is your mobo?

thats the question!

For that mobo, 4.2GHz is 2000% 24/7/365....no need to go more, like 4.4-4.5Ghz

With 4.2Ghz you are way faster, and heating and voltages will be almost like stock.

Have a nice trip!
