Intel Core i7 5700HQ Max Safe Temperature

ReZa546 · Feb 1, 2016

hi.
i wanted to know about the safe temperature of the processor Intel Core i7 5700HQ.
i asked MSI and they had told me that the safe temp is 100c but i know that this temperature will melt down the board.
in game i have about 80C But Sometimes it go's to 85 or 90 But its not permanent and its only for some moments.
i have above 90C temps when i use Intel burn in test V2.
My Cooler its Zalman NC3000S That is the best laptob coolers in my country.
i monitor the temps in windows 10 with HWMonitor pro.
thanks a lot.

The Tjunction is specified at 105C. That is the maximum temperature allowed at the processor die.

what is the ambient. 100C is absurd. really any thing high eighties is not good. perhaps try fresh thermal paste if the warranty has expired, if not pressure MSI to do something as such temps are ridiculous for a laptop. that thing is practically a sandwich press if you close it on one.

Robert Cook · Feb 1, 2016

As said by karsten75 it can run up to 105, but that is terrible to allow. for a 47 watt TDP there is either something wrong with the cooler mounting, or air flow or core voltage.

ReZa546 · Feb 1, 2016

i didn't said that i have 100c.
i said that msi told me 100c its safe
i have around 90c with 5 minutes of intel burn in test V2.
if i could have reduce the turbo frequency that would have been so much better.
i'm sure that 200mhz lower speed can get me 20c cooler.

Robert Cook · Feb 1, 2016

yeah but 90C is still way to high. the fact that they say 100C is okay is crazy. no sane company should say that temps like that are okay. they might not instantly kill the chip but those temps will kill it in the long run. you should not have to underclock to keep it cool. this makes me think the heat sink is loose.

ReZa546 · Feb 1, 2016

actually this is the temps that my other friend that has my laptop(MSI GE62 2QF) said to me thet he gets around 88C too; like me.

TJ Hooker · Feb 1, 2016

Unfortunately, I don't think it's that uncommon for laptops to run hot. Some will even end up throttling performance to try and keep temperature in line. Manufacturers will skimp on cooling to save on space, weight, and/or cost. That being said, I do believe mobile parts are sometimes rated for higher temps than their desktop counterparts for that reason. Maybe manufacturers think it's acceptable to run high temps in laptops because laptops typically have shorter (usable) lifespans that desktops, so they figure the risk of shortening the lifespan of a CPU with high temps isn't as big of a concern.

That being said, 100 C does sound high. That's likely the temp at which the CPU will throttle/turn off, not a safe temperature threshold.

ReZa546 · Feb 1, 2016

how should i change the core voltage or turbo frequency to reduce the temperature?

ReZa546 · Feb 1, 2016

i had downclocked the processor and the temperature now is below 72 but the results of before and after the downclock are like this :
before :

after :
http://www.passmark.com/baselines/V8/display.php?id=55888320581
there is a lot of performance loosing there.
about 1ghz of downclock does that to the cpu.
and i had called the guarantee services in my country and they had said the safe temperature is 75C.
i have 72C with downClock(with intel burn is test V2) what should i do?
did anyone experienced my condition with the same laptop?

TJ Hooker · Feb 1, 2016

Something to remember is that a stress test is designed stress your CPU beyond normal workloads. I wouldn't be overly concerned if you go a bit over the safe temp during a stress test, as long as you're staying under during regular use. 75 C for a safe temp threshold is a little lower than I would have guessed (I would have figured it'd be low 80s or so), but I guess they would know best.

You could try contacting MSI about your high temps. If it's still on warranty, you could possibly RMA it and get them to re-apply thermal paste. Underclocking it by 1 GHz is pretty significant, and I would really hope that isn't necessary.

ReZa546 · Feb 1, 2016

is there any normal stress test that i can use it to know that the temps are good?
however i should tell again i tested one game (AC:Syndicate) and the temps didn't look so good

TJ Hooker · Feb 1, 2016

I would say to just play some demanding games (or whatever other demanding tasks you do with your laptop) and leave a program monitoring your CPU temp in the background. After a while look to see what your max recorded CPU temp is.

But if you've already done that with Syndicate, and you're getting bad temps the same (or close) to what you're getting with a stress test, I'm not sure what else you can do. Other than contact MSI, I guess you could try cleaning/dusting the laptop.

ReZa546 · Feb 2, 2016

witch temperature monitoring program gives me a diagram so i can understand where the temps go over the time?
thank you

TJ Hooker · Feb 2, 2016

MSI Afterburner has temperature graphs. I'm not sure how much time is displayed, might be adjustable. Same thing for CPU-Z. I sometimes use HWInfo to measure my CPU temps, it displays min, max, and average temperature. It doesn't graph it, but I think it has a 'log data to file' option, and it's probably possible to copy the information from the log file into Excel or something to graph it.

ReZa546 · Feb 2, 2016

thanks
and another question :
how can i change the voltage of my processor?

TJ Hooker · Feb 2, 2016

I'm not sure you'll be able to. Normally this would be done in the BIOS, but this option is often locked out for pre-built systems. You could try a software overclocking tool like Intel XTU, which I think might have voltage adjustment options, but there's a decent chance it'll be greyed out there too.

ReZa546 · Feb 2, 2016

i couldn't load the intel xtu.
msi just e-mailed me again and modified the last e-mail and said they had confirmed the max safe temperature and it is 90C.
and i contacted e-mail live support and i don't know why but they told me that 90c its safe for notebook processors and notebook processor's are built to work in higher temperature than pc and shouldn't have to worry!!!
i don't know what to do.

ReZa546 · Feb 3, 2016

i wanted to get my laptop with a chillfactor 3 or liquid ultra to msi representative to change the thermal paste for me but they said to me that if we change our thermal paste to another we will void your guarantee :|
is there anything that i should do?
any ideas?

TJ Hooker · Feb 3, 2016

If you're still on warranty, I think you should be able to get them to re-paste it for you. Contact them and say you're having high temps, and ask if you can RMA it.

ReZa546 · Feb 3, 2016

they can paste it but they only use their bad quality paste as i said.
and the laptop just got pasted in about one month ago an it's totally new so if they change the paste they wouldn't be any temp changing.

TJ Hooker · Feb 3, 2016

I'm really not sure what else to do. When you emailed MSI, did you tell them that you were having problems with your CPU temp going above safe limits during normal use? Did they have any other suggestions?

ReZa546 · Feb 3, 2016

msi answered me that the processor will downclock at 90c and shut's down at 100c and they said to me that the max safe temperature is 90c :|
they know 90c as safe so if i tell them they will say that it is totally safe and there is noproblem.
this was my first and last purchase of msi.

Robert Cook · Feb 3, 2016

That is very low of them to pull that on you. the only thing to do would be to do the paste your self, which means you would have to try to get that thing open and apart with out breaking any stickers. I am sorry that you got screwed by them. If you have voltage control, which would be in the bios, you could try that, but that also could count as a warranty voiding act.

ReZa546 · Feb 4, 2016

there isn't any useful setting on the bios although i managed to get a program to play with the voltages (throttlestop 8 beta 7) and stabled the CPU VCore to 1.0280 (static) and the temperature wont goes to 90 and it is about 83 with normal applications and 98 with stress test application like prime95.
but there is a problem that i cant put the app on the startup but i'm trying to.
and another thing is that there are stickers that if i open the back of the laptop the guarantee will void and personally i cant and by the place of the sticker's i think no one can
