My Skylake went to 63C for a bit.

I had just finished building my computer, I bought really expensive and good quality parts, and I work with important data i.e. I don't want the computer processor to mess up calculations that I wouldn't know about (text most importantly).

I had opened Open Hardware Monitor and exported a video, then on another time tried the intel i7 tool, and on another go tried the 3D pass mark, even also tried the BlenchMark. The Intel Diagnostic Tool test (and the others I remember) made my Skylake processor usually go around 54C to even staying at 61 for a while and also 1 core ht 63C. I am worried, they stayed at 61C for a few minutes, and have went through a few several times of this torture, oh I am worried.

I am going to try and set their max temp so they automatically settle themselves down, but obviously that's not what I'm worried about right now, I'm worried about if I have melted the any single even 1 of the billions of transistors or wires in the Skylake.

It's max Temperature Intel gives is 71C at the T junction case package.

***I need to know if any signifigant melting to the transistors happens over only a few such occasions or when it reaches 63C every other week it would only add up? Will I be safe or not?

My laptop's max safe CPU temp is 100C and on big full loads is sometimes 78C, though high like my Skylake it is still way under the death-zone limit.

63C is fine for Skylake under full load. They can handle quite a bit more than that.

On your use case though "I work with important data i.e. I don't want the computer processor to mess up calculations that I wouldn't know about (text most importantly)." If perfection is that important you should be using Xeon with ECC RAM. Consumer grade hardware is not meant for ultra critical scientific work.
Modern Processors are made to withstand very high temperatures, and don't start throttling until around 104c, if it doesn't reduce the temperature from then, it'll shut down from overtemperature protection.

63c is completely normal for any processor, and in most cases, is quite a good temperature to be at under load.

There's nothing to worry about with it being at 63C, and it will not reduce its lifespan quicker than it being on 40c, you'll need to upgrade before it dies.

With it being a laptop, cooling is limited, and with it being 78c is still somewhat normal, most people tend to stay under 70c, and some people under 80c, anything above is too much, and for me, personally, 70c is the limit.
 
But then why does Intel Ark website say my Skylake i7-6700's max CPU temp it should ever get is 71.0C at the limit???? I want this thing to be "over-protected" from even being near a danger-zone.
 
Kind of confused, is it a laptop or computer you've built/are worried about? Since you talk about both in the thread.

And that is the TCase, that is different to TJMaxx or anything, read on this thread for further explanation, Im terrible at explaining things so 😛

http://www.tomshardware.co.uk/forum/302869-28-diff-tcase-tjmax

If you take a look at the TCase for the 6700K, it is lower than the 6700, but it allows overclocking and produces more heat, and it is still safe to use: http://ark.intel.com/nl/products/88195/Intel-Core-i7-6700K-Processor-8M-Cache-up-to-4_20-GHz

I have an i7 6700u in my laptop, and that gets to around 70c I believe, and it is perfectly safe to run.
 
71c listed in intel's ark is tcase which is the temp at the ihs. That's not the same as the core temp which is what you're seeing from software thermal monitors like realtemp or the diagnostic tool. The core temps will be higher.

Have a read here.

Also keep in mind than many stress tests will push a cpu harder than standard programs will. 63c is a perfectly safe temp.
 


+1

Basically how I would've put it if I could explain things 😛

 
I built a powerful desktop, was refereing about my kitchen laptiop.

If nothing inside it will melt then why would intel say 71C is mine's limit while self shutdown is around 100 maybe? They want us to avoid melting all those 14nm transistors right? They are like 30 atoms wide, add some photons, and...wam..

So I will make the CPU not able to run as fast, damn that Turbo Frequency! 4.0 for Skylake! 3.4 is is for YOU!

:)
 


You basically explained it yourself, the CPUs aren't 100% silicon, and the PCB that is involved, there's gold I believe (Used for pins). These aren't necessarily 'melted' at specific temperatures, but there will be burns and damage to the CPU. There are most likely really small transistors and things inside the CPU (Notice my insane explanation skills 😛) which will have a much lower temperature to not be damaged.

Explained here also, and by people who can explain things :lol:

Well the melting temp of solder is 188 °C. I say that becuase you're obsessed with something melting on your processor, and solder is the thing with the lowest melting point.

I also mention it becuase your processor is soldered to a small board, so in the process of being manufactured, your processor was cooked to at least 188 °C, probably a lot more.

So no, running your processor at 63 °C will not cause you processor to melt and dribble out of your PC.
 
Then why can't it work past 130C? Cus it melts! You're wrong. The transistors & wires come apart some way.

Also what gives this one article n comments say 100C is intel's throttle down limit, then what is the 71C at Tjunction all about.

Also how many degrees celcious would 4.0 down to 3.4 change from no turbo? 3? 8? 14?
 

I do not want to look up the different materials chemical composition and melting points. That being said I am fairly confident that electromigration, thermal fatique and expansion becomes an issue way before anything "melts".

I understand you are worried, but it does not sound like anything is at an immediate risk.
 
Really starting to wonder if you're a troll. Thread after thread of the same stuff. Do you read everyday about CPUs "melting" or "melting transistors"? No. Doesn't happen. Even if your cooling fails and the CPU hits its thermal limits the CPUs has safeguards built in to protect itself. They don't "partially melt" and fail after a few days or weeks.
