I know this has already been posted elsewhere but that post seems locked.
I recently built a customer an I5 pc with 8gb RAM 2500K CPU and a 120gb SSDusing an ASUS motherboard.
The I tested the temperatures before delivery and even under bechmarking the CPU temp never went above 55 C
however after installing NIS 2012 when performing a manual scan the temperature hovers between 45-57C spiking for
1 second as the scan finishes to 72-74C. After that 1 second spike the temperature immediately drops back to 35-40C.
The fact that the temperature peaks then immediately drops back without "cool down time" suggests to me that NIS is somehow corrupting the onboard temp sensors.
I have checked the temps both with NIS and with ASUS own monitoring software and they both say the same.
Any help would be appreciated as this doesnt look too good as far as my customer is concerned.
NIS is an application that shouldn't have any real thermal effect on a properly designed system, IMO. Even though it has processes that take up more CPU time than others, due to the nature of the software, I highly doubt it is the actual problem.
Being that you have an SSD makes this even more weird. Have you used a Benchmarking utility to stress the new system and take a look at the aggregate thermals and the individual components? Isn't that Intel 2500K an overclockable processor?
You state that "I have checked the temps both with NIS..." ? This needs a bit more study on your part, I would think.
Please post back with more detailed data and we can examine it.
Hi there. I used both the benchmark on pcpitstop.com and the benchmark in pcwizard and the temp never exceeded 55c I will try running prime95 and soak test.
Sorry to hear of your issue and can appreciate your concern ! As A_B says....I too think that NIS processes may not be the sole cause of the thermal issues you are reporting .
After many years building and repairing units myself ...I know only too well that some strange events can occur that can often point us toward a mistaken conclusion .
I now use laptops more than desktop systems , and allowing for the fact that a laptop is much more liable to thermal issues due to the limited internal archtecture layout and a natural tendency to have limited airflow around the important areas such as the processor and graphics adapter locations , I can honestly say that even on my i5 laptops which both have dedicated graphics adaptors and Hybrid SSD drive upgrades to both ...I have never experienced any thermal issue regarding core temps that have given me cause for concern when NIS is scanning the system thank goodness !
Can you advise of your ASUS mobo spec , as I know that some variants can differ in the way the onboard sensors report etc ;
Let us know how the "soak test " pans out and it might help us a bit more..Meantime I'll have a trawl around and see if there's any similar occurences reported ?
OK just got back from my clients and there were a couple of issues. Firstly the motherboard had been set to extreme which would account for the temperature spike. I have reset to power save mode and now the temperature during scan peaks at 51c which is a lot better.
However I have noticed that when running a scan and monitoring with PCWizard the load on all 4 cores peaks at 99% and stay there for 2-3 minutes. This of course will increase the temperatures.
I have the same CPU and board on my personal machine and use a certain reptile based free Internet Security Suite and when I run a scan the load doesnt go above 75% so my question is on my customers machine what can I do to reduce the load.

Efficiently written code. It keeps the computer busy.
> I have the same CPU and board on my personal machine and use > a certain reptile based _free_ Internet Security Suite > and when I run a scan the load doesnt go above 75%
Poorly written code.
It figures. In almost all cases*, people who create _free_ programs don't have the same resources -- time, money, manpower -- that major corporations, e.g., Symantec, have.
* Not 100%, just 99%. ccleaner being an example of a well written free utility.
OK I see I am getting nowhere here. The first thread does relate to overheating but does not "PROVE" anything. The second post does not even relate to CPU temps.
As for good programming fully utilizing the CPU what complete garbage. I have a friend that is a comercial programmer and when I told him this his words were "What a load of tosh". A well written piece of code would not max out the CPU the better the programming the less resources are used.
I think I will just have to suggest my customer uses an alternative AV product.
I have been building systems for customers since 94 and have known for sometime that Norton is a system hog I just thought that an I5 with 8GB ram wouldnt struggle with it obviously I was wrong.
