Windows 7: PC Shutdown after Orthos Stress Test.

4 Gig · 01 Jun 2011

I was considering undervolting and decided to see how hot my CPU would get under load before I undervolted. Two days ago I ran Orthos for a few minutes and watched my CPU get into the mid 90's C. After I terminated the program I noticed that TZ00 in HWMonitor stayed at 105 C for a couple of minutes and then the PC shutdown. The CPU temps returned to normal.

Since then things have been OK but the TZ00 temp is still about 10 degrees higher than the CPU temps. What exactly is the TZ00 sensor and after this episode was permanent damage sustained?

Thanks for any replies.

Laptop or desktop?

The TZ00 sensor is part of the ACPI sensors on the motherboard. Do a google search for TZ00 and for ACPI and you will get lots of hits on these.

It's a Dell laptop according to his system specs

It is a Dell laptop and one that seems to run hot according to other forums. Can you all see my system specs? I plugged them in the user CP but I cannot see them displayed along with my posts.

Ya I see, this laptop is pretty damn good, I'm jealous. It runs hot because it is the fastest (and hottest) Core 2 Duo Mobile Processor of its time, plus you have 8GB of RAM and a pretty good GPU. I have even used a Dell Studio laptop with WAY less specs than yours and it still runs pretty damn hot. Instead of telling you how to make your laptop run cooler, I am going to give you the link to a website with extremely good info (I can't explain it any better) on how to do so. It helped me cool down my old 9-year laptop tremendously which used to shut down regularly every 2 hours from heating (it runs a Pentium 4 3.06 GHz lolz.)

Thanks, I do regularly open her up and blow out dust and I use a cooling pad. I guess I went a little nuts on the hardware. The original CPU was a P7450 2.13 GHz which ran fine before I swapped it to the T9900. Ever since I installed an SSD I was thinking about going back to the P7450 if the heat remains an issue.

I guess you should switch back to your older processor. Please tell me what you do exactly with your laptop. Do you game? The SSD is good, as it helps reduce heat, as unlike HDD's, they don't don't spin. But the max heat of the T9900 is a whopping 105 degrees Celsius. Ouch! And the P7450 uses (at max) 10 watts less than the P9900. You should try buying Arctic Silver and applying it. There are cases that report a whopping result of 30 less degrees Celsius than normal.

That's the thing, I don't game or do video editing on it any more. I upgraded under the assumption that I would. I will most likely return to the older CPU. What I wanted to know was if I did damage to this system when the TZ00 sensor hovered at 105 C. The system shut down and I haven't seen any other issues so I guess it's OK. Thanks for the tips!

Orthos is a stress test that puts an unrealistic load on the machine. You use it to check if an OC is stable. Normal operation, including the most demanding games available don't stress the cpu(s) nearly as much as Orthos.

I would not run it on a laptop. About the only thing you'll do is generate excessive heat.

The laptop shut's itself down to protect it from damaging the hardware. It will still kill the hardware if it regularly goes at high temp's. Can you please check your temp's at idle while using light apps such as web browsing and word, and when playing a game with HWMonitor CPUID - System & hardware benchmark, monitoring, reporting and report the result's back to me thanks.
