idle/load temps of T7200

Hello.
I'm trying to find idle and load temps of the T7200.
I just replaced my T2050 1.6ghz Yonah with a T7200 2.0ghz Merom, and though the idle temps are about the same, I never really noticed the load temps of the old processor.
My idle temps range from 44° C to about 49° C.
My 100% load temps (taken from Intel's Thermal Analysis Tool v2.05) are about 75° C per core. This TAT application has a more stable and even workload than other benchmark/loadbearing stress tests.

Anyway, I got worried once it got as high as 75° C, so I stopped the workload. Then I did some research.... The Conroe Desktop Core 2 Duo's have a Thermal Specification of about 61° C, and having your E6600 or better above 63° or more is not good (from what I've read around on some forums). However, Intel states that the Thermal Specification for the mobile Merom Core 2 Duo is 100° C. Throttle begins at 101° and shutoff at 106° C.

So, with that, I feel a little better about my temps, however if I can find a replacement fan/heatsink that will fit my notebook, I will consider upgrading the cooling unit.


Do you have a T7200? What are you idle and load temps?

I downloaded Intel's TAT 2.05 from http://www.techpowerup.com/downloads/392/mirrors.php

 

Replacement fan units are available, but none of them are different to the one you have now. Notebook cooling systems are proprietary to that notebook, and are not interchangeable. I wouldn't worry about the temperature, as its safe for the temperature to go to 75 C. If you fell uncomfortable with the temperature that high, you may want to consider a notebook cooler. They can reduce temperature of most components alot.

 

So if the Thermal envelope specified by Intel (100° C) is reached, the cpu will throttle and go down?

I'm afraid the cpu might shutoff during a rendering and lose unsaved project data, or some similar operation.

 

Intel CPUs have been programmed to shut down when they reach a certain temp threshold to prevent damage.

so yeah itll shut down when it reaches this threshold.

did u apply thermal paste on it when u installed it?

btw T7200 temps on my dv9000t using TAT are 22C idle 55-60C load

 

yes, i used Arctic Silver 5. I doubt I applied it incorrectly because i've done it before, but I would try it again if the concensus here says the temps are too high.
the T7200 did not come with my notebook, so the old cooling unit may not be well-equiped for a hotter cpu.

 

After addressing the thermal pads/compund thing...something else you can do instead of a cooling pad is use a small desk fan. I keep a fan in a couple places wournd the house in places I like to work. Then I can blow air at the back of the system and under it...kills two birds with one stone...cools down the laptop by moving more air and it helps keep me cool too.

I am sensitive to keyboard temps and found the desk fan to be the only solution that works. It has the added bonus of cooling the laptop too.

I went so far as to get a couple of the Vornado Zippi fans...they are really nice looking and I can take one with me when I am mobile or travel. Of course a plain old $9.99 special works GREAT too. Just thought it was fun to add a "stylish" toy in the Zippi... They are actually only $20/ea on the Vornado site with pretty reasonable shipping. It worked out cheaper then buying on eBay...

 

the idle temp is quite high i reckon, unless you're not using the full sleep/speedstep modes of the CPU in which case that would explain it.

 

I've looked in the Thermal Analysis Tool and see that it reports more than one temperature. There are the two core temperatures but also, in small print, the ACPI thermal zone temperature. On my computer this is usually about 5°C cooler. By comparison of the different displays, I see that MobileMeter reads the ACPI temperature but RMclock reads the core temperature.

Anyway, on my X60 plus running at 100% workload at design CPU voltage (1.187V on my T7200 - other T7200s may have different voltages). I managed to get the core 2 temperature up to 90°C (it runs 1 or 2°C hotter than core 1), with the ACPI temperature reading 85°C. I then put the CPU voltage back to my usual maximum voltage of 1.05V (using RMclock) and this dropped the temperatures by about 10°C at full load (cores 79°C, Thermal Zone 74°C).

By comparison, the light use temperatures: are both cores 59°C, Thermal Zone 54°C in a room with ambient temperature of 27°C (I have difficulty in believing sideswipe's idle temperature of 22°C unless he is in a freezing room). However, my light use is not that light - Task Manager is showing 40% - 50% CPU utilisation - Firefox is taking a lot of power for some reason, but that is outside the topic of this thread).

PS: The culprit for the high idle CPU usage is a snowflake Flash banner ad at The Inquirer. Anyone know how to cripple Flash so it goes slowly?

 

lol i dunno man thats wat RMClock is reading and sometimes it reads even less but mobmeter reads that temp too. NHC also had my idle temps between 22 and 28C. same goes for everest and speedfan. the reason your temps are high could be cuz of your CPU utilization, kill firefox and see what ur temps are.

 

I'm running TAT on my Q35 (T5600) which is idle and running on battery. MobileMeter is showing total power drain between 10W and 12W. The fan isn't running and TAT shows the CPU core temperatures as 38°C while the ACPI Thermal Zone temperature is sitting at 44°C . TAT shows the CPU C state as C3 for both CPUs. The only way I could get the CPU temperature lower is to force the fan to operate, which isn't necessary since the computer is only slightly warm. Even with the fan running, I doubt whether it could get the cores lower than about 10°C above room temperature since there needs to be a thermal gradient in the cooling system.

Conclusion: Your computer must have a good cooling system to get the core temperatures as low as is reported and/or you are in a very cold room.

John

PS: I've now installed the Flashblock add-on for Firefox and the CPU utilisation has dropped dramatically, but the core temperatures are still sitting at 55°C.

 

to be honest sometimes i think the CPU is misreporting the temps as RMClock drops even lower than that on occasion. the highest its ever gone on idle was 33C and the fan turns on and brings it down to 28.

and btw im in dubai where AC is on 24/7 but it isnt cold, its around room temperature. ur in the UK it shud be colder there. maybe i shud start a thread in the HP section about CPU temps so i know if mines normal or not

 

i want to go to dubai!!




:sorry, off topic.

 

I'm actually in Cambodia at the moment. Even nicer than Dubai (where I find the central A/C systems are often over-zealous). That said, the office A/C has a problem so the temperature is 29°C today and a it's a little warm.

But this highlights the fact that any discussion of computer temperatures needs to take account of the ambient temperature. I have found that that the HDD temperature in normal use is usually a fixed amount above ambient for a particular type of HDD and computer. (The Samsung HDD in my X60plus is currently at 42°C, which is only 13°C above ambient. I used to have an Asus W3A and the HDD ran at 20°C above ambient.)

I'm confused. Speedfan shows idle temperatures between 25 and 29 degrees, rmclock shows idle temperatures over 40. I guess they are measuring different things, but almost 15 degrees difference seems a lot to me.
