A8Js @ 95C

The fan did not kick in at all, there was something wrong with the ACPI so the CPU heated up till 95 Celsius until i noticed that the fan was off and i shut down the pc. Now its working again but i am worried that this hight temp could have damaged the device.

Any remarks ?
possible?

 

That is a very high temp, but I doubt you damaged anything. I was reading reviews on SilentPCReview of Core 2 Duo desktop systems and they didn't thermal throttle until 100C. The CPU would slow itself down automatically in hardware if it was in danger of being damaged.

Be careful with those NHC ACPI routines!!

 

Sure thing, you are saying that there is a hardwired shutdown threshold in all C2D processors? I cant Imagine that 95C did not fry and parts in the processor, how can i make sure no damage has been done? When a C2D throttles down at 100, is damage prevented to a 100% certainty or will it damage the cpu?

Thanks

 

If you're using NHC, I don't think there was a native profile for the A8j model. I've had some issues with the ACPI in NHC messing with my Z63 (W3A) after altering the W3V profile, like disengaging the fan after hibernate recovery, so I disabled ACPI for exactly that reason.

Yes, all of the mobile Intel processors have automatic shutdown sequences built in if the thermals hit the designated level to *prevent* any damage from occurring. A single run up to 95C will not damage the processor (constantly running it that high, maybe), but your C2D is fine. You can relax and go back to enjoying your sweet machine .

 

Newer CPUs have much higher maximum junction temperatures then the previous generations.

 

Hi guess if you want to test whether there was any damage to the CPU you can run a program like cpu-z to test the CPU.

Be very careful though as it will stress the CPU so it will heat up so be sure the fans will be working ok.

 

I am willing to bet the cause of your fan not turning on is some kind of program that mods the fan speed or monitors it that was installed by you. My advice? format and avoid these programs in the future or remove whatever you think may have caused it. It is possible for the fan to fail but your acpi theory is caused by user error. I may be wrong but most of the complaints on the forums were caused by users installing fan modding utils.

 

Yes Id like to agree with Eddie on this.

The problem is the program nhc. This is a dangerous program.


I see so many people talking about it, and those were all the same people complaining about the fan noise in their a8js.

Dont use this program. I have it installed and disabled but this program is bad news.
I dont personally want to even try to give tech support to people who are using this program because its the cause of the problem.

This program was on my a8js long enough for me to understand its bad news just let me say that in short.
Its extremely popular but I just have to tell you dont use this thing.

Very unstable program. You need to hook up with seperate functions. Use power4gear its way way better for power management. Use everest to check temperatures its way way better.

Use fangui to mess with your fan.

Do not let power management mess with your fan. Do not use this program its a bad idea.

 

I think you're overreacting a little. Notebook Hardware Control (NHC) is very useful for undervolting, monitoring system power consumption, hard drive SMART status, battery wear and charge, etc.

However, the ACPI part of it (which allows fan control) is very new and very experimental. It is OFF BY DEFAULT. There are a ton of warnings about what can go wrong if you turn it on.

In general I'd say NHC is useful, but not the ACPI part of it. Which is why it's normally disabled and requires lots of user intervention to mess with.

 

I have nhc installed. I only use it to check battery wear and then i put it back in the closet.

It has a lot of utilities at once.

I give the program low marks for every single thing it does.

Ok if you want to use it that makes sense, dont use acpi I think its safe then. Just poor.

Im worried about new laptop owners getting advice to use it to undervolt and set the fan on their laptop. Its dangerous.

I dont like it.

 

I use NHC constantly, and I find that it's a very useful program for the cautious and well-informed notebook user. However, if you're underinformed about using the specific utilities that NHC uses and you start messing around with stuff, you can definitely hinder your computer's functionality.

 

Well Im trying to say two things ok..,

One is its a dangerous program

two is I think its a bad program even if it wasnt dangerous. But thats just my opinion it might not really matter to the first point. Its sort of an added anyways.
You dont have to do things like me lol but I use seperate utilities to cover the nhc ones.
The program itself freezes and causes slowing and crashes. It has failed my real use test already.

it is extremely useful in the amount of utilities in one program, in its quantity of utilities it is unmatched.

next you want to have this thing controlling your fans turning on and off? only on the company's laptops

 

I had NHC running and then i installed PowerGear (Asus). I went into Standby and back, then the fan was not functioning anymore. I deleted PowerGear now, leaving me with NHC wich worked fun up until i installed PowerGear.
So, you are absolutely positive that this single occurrence did not damage or shorten the lifetime of my CPU and other parts in any way? I could only imagine that 95C would melt plastic so how on earth would my machine get away without any damage?

 

I'm 99% sure that your computer is as good as new. My old laptop used to get around 90 degrees celsius when under heavy stress, and that was how it was designed. You know, if the processor couldn't handle 95 degrees, it would have lower temperature limit. The limit is there because of cooling failures and your case what just happened there, is a cooling failure. Your laptop is fine. A8Js can get normally near 80 degrees when under heavy stress so an extra 15 is not that bad. AND you can also plug in intel's more expensive cpu models that run even warmer than core2duo 7200.

Just relax if your computer runs ok Well you can open up the cpu/gpu containment and look for some melting etc but I'm sure you won't find anything, mostly because there is none

And regarding the NHC question thats floating in this thread, is it safe or not. I'm sure that a normal user can't make any damage to their laptops when using NHC features like undervolting. Undervolting in fact can increase the laptops lifetime. On the other hand, ACPI programming can be dangerous, but there's a clear warning in NHC for that.

 

95C is not enough to melt the plastic on your computer. It is only hot enough to melt a thin plastic bottle. Now, you did not do any immediate damage to your computer, but you might have lessened the life of your CPU. But if it was only running at 95C for a short period of time, don't worry about it too much. Almost all GPU's and CPU's have a core threshold, and if your components reach that threshold your computer will shut down, to prevent further damage.

 

CPUs can handle much more heat than we generally assume. I had a Athlon 1700XP desktop chip on watercooling a few years back. I fogot to turn on the pump and went merrily on my way for about and hour till I smelled something. Well the chip got hot enough to melt some of the solder used in the waterblock (DD Maze II), I was sure I had fried it, but it booted right up and ran fine for another year untill I sold it to a friend. Melting the solder puts it at around 110C (melting point for low temp solder), I think. Turned the copper a neat blue color over the core as well

 

thanks for the great responses, the device seems to work fine. Just sucks that i might have lessened the CPU life time. Hope its not the case.
