Hardware Temperature

[Grand Cherokee]

Hello.

I have seen here at #26: http://www.aida64.com/support/knowledge-base

That those are ideal temperatures that we should mantain to run everything fine.

Question is, those temperatures are valid for laptops as well?

Under load, motherboard temperature can reach more than 60ºC and cpu #1 and #2 reachs temperatures next to 70ºC. Only cool and nice temperature is the HD, it never really pass 40ºC.

Even at idle at 997.5mhz, multiplier 6x, it will eventually reach 60ºC, but then the fan speed increases and temperatures goes down till 45ºC and then the fan speed goes down. And the whole thing starts again at 60ºC.

Its a Pentium dual core T3400 2.16ghz, motherboard is a OEM I42IL1, hardrive is a Samsung HM320II. Bios is a Phoenix from 07/15/09.

About Intel SpeedStep, it only alters from 2.16ghz multiplier 13x to 997.5mhz multiplier 6x.

So even when I'm running an old game like Sim city 4, the processor locks at 2.16ghz and the thing starts heating up. It shouldn't "overheat" to run this game at an intel gma x4500 and 4gb ddr2 667mhz. Heck, even when I play an ol genesis game from 1990 using an emulator it happens.

I've opened it, there is no dust. At bios I have no option to alter fan speed like the QFan utility.

And yeah, almost forgot... I'm using last version of AIDA64 Extreme Edition, 2.00.1700 stable version.

Is it okay? Or should I do somenthing, if yes, what can I do?

Thanks.

Mobile computers implement serious constraints on case space and fan sizes to make sure they are portable. Hence you cannot expect the same cooling performance from a mobile computer than from a desktop computer. Generally speaking, hard disk drives should be the same in mobile and desktop computers, but the mobile motherboards and mobile processors can stand a bit more than their desktop counterparts. So as long as your CPU isn't overheating, you should be fine.

You can check CPU overheating in the AIDA64 System Stability Test by enabling only the FPU test, and pressing the Start button. Watch the bottom graph where Throttling should never show any non-zero percentage activity. When your CPU is throttling, it means it is overheating. A properly designed computer should be able to run such a heavy workload like AIDA64 FPU stress test without the processor overheating.

I've runned System Stability Test with only FPU Test enabled for 10 minutes. It showed cpu usage at 100% and 0% cpu throttling all the time. Temperatures of motherboard and Cpu #1 Core #1 and Core #2 never passed from 48ºC, HD temperature didn't passed from 30ºC. For about a second, temperatures of Cpu Cores showed 54ºC and then returned to normal. I wonder if the sensor is okay.

I've used Everest 5.52 beta before I jumped to AIDA64 and motherboard temperature never passed from 50ºC. I don't know why it reachs 60ºC under load now.

Well I found it quite strange so I went back to the AIDA64 tab where it shows computer - overclock and saw that the speed of the processor was locked at 997.5 mhz multiplier at 6x, during the FPU Test. Shouldn't it be at maximum 2.16ghz and multiplier 13x, since it shows cpu usage at 100%?

Intel SpeedStep interferes with this test? Thats why te sensor showed quite "low" temperatures, no?. I gonna disable SpeedStep next time and see what happens. Also, how much time should I leave the FPU Test running?

By the way, whats ths FPU Test?

And, do you know whats the motherboard brand?

Thanks !

Forgot to say that at "sensors" it does not show the fan nor its speed. Also, looks like that the motherboard brand/model is Uniwill I40, I think. Never heard about this brand, although when I type Uniwill at google it shows ECS ELITEGROUP brand. Here: http://www.uniwill.com/

Thanks !

1) On mobile systems you may need to alter the default setting of power management features (like SpeedStep) to make sure your computer will be running at HFM (High Frequency Mode) under heavy load. With certain settings that some manufacturers call "Battery saving mode" the computer will always work at LFM (Low Frequency Mode), no matter if the computer is running from AC or DC power. You have to make sure to check the current power management settings, although in most cases to get a mobile computer to work at HFM is easy: just connect it to AC power

2) The FPU stress test usually heats up all system components in 15-20 minutes.

3) AIDA64 System Stability Test is a lot more sophisticated and is better optimized to the latest processors than what EVEREST used to offer -- that's why with AIDA64 it's normal to reach higher temperatures due to the heavier workload it puts on the system. EVEREST is an obsolete and discontinued product that e.g. doesn't support any processors released in 2011 (e.g. Sandy Bridge, Bulldozer, Llano).

4) The FPU stress test uses a heavy workload, based on floating-point calculations, to fill up all the floating-point processing units of the processor with calculation threads. It stresses all available CPU cores and CPU threads, and it utilizes every relevant modern x86 extensions such as SSE, FMA4 and AVX. Modern processors can be heated up to the highest level by running exactly the type of worload that AIDA64 uses in the FPU stress test.

5) Most mobile computers cannot measure their own fan speed, but only able to control the fan speed based on the measured CPU temperature. Unfortunately most mobile computers are not equipped with a sophisticated sensor chip (due to size constraints on the motherboard PCB).

6) I42IL1 is most likely produced by Elitegroup, which manufactures a lot of different motherboard and notebook brands, e.g. ECS, PCChips, Uniwill, etc., and their products are rebranded by an even bigger number of computer assembly companies. Elitegroup a huge company, but since we're not sure which brand the notebook product called "I42IL1" belongs to, we show what DMI reflects. And DMI holds the manufacturer name as "OEM" on your system.

1) I will have to alter the power management to HFM, because it was connected to AC power.

2) Good to know, will do it.

3) I'm sure it is. But I meant that Everest gave me a different temperature reading than AIDA64, during normal use, not using Test Stability Test. Motherboard temperature never passed from 50ºC under load at Everest, now in AIDA64 it can reach 60ºC, under load. Maybe it is because Everest wasnt so sophisticate like AIDA64?

4) Great. Lets hope the laptop doesn't want a retire from all this stress . Thing here only have up to SSSE3 instructions. Its a 65nm Pentium dual core. I wonder what I lose for it not being a 45nm variant and not having SSE4.1 instructions, more cache and such stuff. Damn it would be cooler than this model as well, don't know how much, but I'm sure it would.

5) I have no option to control fan speed, not even at bios. Too bad I have an inadequate sensor here, the thing might want to boil eggs and I didn't know about that, nor its intentions

6) I don't know what DMI means, but that thing gave me a name, I42IL1. If it was made by Elitegroup, I guess I'm fine about those high temperatures. I've seen that they make lots of stuff, motherboards, video cards and so on.

When I'm able to run the FPU Test at maximum processor frequency, enabling HFM, I will post results.

Thanks, Fiery !

Different core temperature on Intel processors before the Core i3/i5/i7 era could be due to different TJMax value used. If you believe AIDA64 measures 10 Celsius more than what it should, then try to set a lower TJMax value in AIDA64 / main menu / File / Preferences / Hardware Monitoring.

[Grand Cherokee]

I don't know if AIDA64 is really measuring a higher temperature than it should. Is there any other option I can try?

Anyway, I played with those TJMAX values, it is set to automatic and I have the option to set it manually between 70ºC and 125ºC. If I set TJMAX to 70ºC, processor #1 and #2 temperature goes down from 46ºC to 17ºC, if I remember well, bellow 20ºC for sure. If I trie a higher value, like TJMAX 90ºC it goes to something around 34ºC.

Other than that, I tried to run the FPU test with Intel SpeedStep disabled, tried... I have changed the power management settings from Portable/Laptop to Home/Office. It shoud disabled Intel SpeedStep, at AIDA64's overclock section it clearly states maximum 2.16ghz processor speed and multiplier 13x. But when I attempt to run FPU test, it goes down to 997.5mhz and multiplier 6x. There is no option to disable Intel SpeedStep at bios, it is too simple. A lot of options that should be there, aren't.

So huh, what should I do?

Thanks !

[Fiery]

AIDA64 follows Intel's public DTS specifications, hence it should measure the right values if you have the right TJMax value configured. Automatic value means AIDA64 will take the TJMax value published by Intel, hence it should be the right one to use. The now discontinued Everest used different TJMax values, which may or may not be the right ones. But the right ones are now used by AIDA64.

If you cannot get your notebook to operate at HFM at 100% load, then there's definitely something fishy about your system. You can check BIOS options, Power Management options (in Windows Control Panel), but if nothing helps, it may worth disabling or completely removing the manufacturer supplied power management software(s) you may have installed.

[Grand Cherokee]

Hey there.

1) Yeah, right values. I tested Hwmonitor and Speedfan and they showed me the same temperatures. Same thing, motherboard can reach 66ºC and processor cores at 74º, under load (happened some times, usually it sits at 64ºC and 71ºC motherboard and processor cores temperatures, respectively). Thanks for the explanation.

2) Like what I said, this BIOS is too simple, there is no option to deactivate Intel SpeedStep, nor any other important stuff. Just HD operation SATA or IDE (my case, since I'm running WIndows XP Professional SP3) and some other simple things.

At power management option, in windows control panel, everything is fine or at least should be. Home/Office profile should deactivate Intel SpeedStep but when I attempt to run FPU Test, things "revert" back, like I haven't deactivated SpeedStep. Don't know why, since at AIDA64, overclock tab it shows 2.16ghz max frequency and multiplier at 13x, but during the test it slows down to 997.5mhz and multiplier at 6x.

Other than that, there is no manufacturer power management software, not that I know of. Only drivers I downloaded are: Chipset, Audio, Modem, OSD( don't know what is this), Touchpad (although I'm not using it right now, didn't like it, I'm using the default windows one), VGA drivers, Lan and WLAN. All these drivers are from the manufacturer, all of them are for Windows XP and at their description it has the same name I40, like I40VGAXPIn.exe and I40OSDXPIn.exe.

Thanks for your time.

Hi there.

I've set processor affinity to some "heavy" programs (like a light game, Sim City 4, The Sims 2), so they can only run at core #1. Doing this temperatures stay down 63ºC, better than at some cases, more than 70ºC. Still, I don't really understand why motherboard temperature stays the same as the processor, around 60ºC.

And why cores temperatures variates so much, like 3ºC to 5ºC more than the other core, they rarely stay the same. Its at the same chip, so why? Sensor inaccuracy?

Do you want me to send a report? If so, how?

Thanks for your time !

[Fiery]

Intel core temperature diodes are well known to have accuracy issues. Accuracy is only guaranteed close to TJMax. You don't need to worry too much about temperatures as long as your processor is not throttling under heavy load.

[Grand Cherokee]

Yeah, I'm accustomed with desktop temperatures. I "had" one (It is locking up, I tested memorys, but the problem looks like is in the motherboard, so I forgot about it for now, thing is quite old.) with a nvidia chipset, MCP temperature never passed from 50ºC and all other components never passed from 40ºC.

Everest never showed me a temperature higher than 50ºC at this laptop. By the time I installed AIDA64 2.00 it jumped to 60ºC... at the same moment I said, well what is going on? So yeah, I was concerned about it, especially after reading tis, at #26: http://www.aida64.com/support/knowledge-base

What should I do about the FPU Test not running accordingly? Do you want a report about this issue? I really don't know about any power managment OEM software. I don't know if I explained this well at post #10.

Thanks Fiery !

[Fiery]

I'm pretty sure the HFM issue is not related to AIDA64 at all, so I'm afraid I can't help you about that. AIDA64 does change power management settings before running benchmarks, but it changes them in a way to squeeze out the most performance from the CPU. It definitely doesn't alter power settings in a way to make the CPU run at LFM.

As for the 50C vs. 60C issue, you can lower TJMax temperature (in AIDA64 / main menu / File / Preferences / Hardware Monitoring) if you're adament that Everest was more accurate on core temperature measurement.

[Grand Cherokee]

I'm gonna talk to the manufacturer then. Last time they didn't help me at all, but with this new information, lets what they will gonna say now.

Oh no, I'm not saying that Everest was more accurate than AIDA64. I was just expressing how worried I were about the temperature differences. Since you explained to me that AiDA64 follows Intel specifications, not to mention that you said if the CPU is not throttling, even with these somewhat high temperatures, I should be fine.

I said that I was worried, but now I'm okay.

Thanks !
