I've used Speedfan and several others for tempurature monitoring, and it always picked the wrong sensor to use, giving me readings from -70º C to over 100º C, both obviously wrong. MC |

A REAL reading of 106 degrees is probably impossible with a Pentium 4; the CPU would have ceased operation before that high a temperature was reached; first it would have throttled down and then errors would have locked up the system. maybe it won´t ! remember that famous video with pulling the HS off? there was 118°C !!! Thermal throttling locked CPU not to get into a thermal runaway !!!! (win did not crash!), neither Cpu died! probably, or is HSF mounted very badly or the reading from onDie diode is toasted (but he says that HS is hot!), something is wrong! (Btw, I run once my Tuallie w/ MoBo thermal throttling engaged up to 90°C from Cpu diode reading ... it survived, still kicking .. :-) ... -- Regards, SPAJKY ® & visit my site @ http://www.spajky.vze.com "Tualatin OC-ed / BX-Slot1 / inaudible setup!"

I'm certain that my CPU (P4 3.06gHz) is running far too hot and is the cause of my unstable PC. The manufacturer claims the temp is normal for this type of system - which is more like a laptop than a desktop, as the motherboard and cards are built in behind the TFT screen and the hardrive is built into it's base. They actually say 108-113C is 'normal', or do they say that it's normal for their system to report funky temps? Well, first, is it a desktop P4 3.06 gig or a mobile and do you know what the temperature reading is coming from? I mean, case temp, as would be the proper measurement for a desktop P4 or on-die temperature diode, as would be needed on a mobile? The max case temp for a desktop P4 3.06 gig is 69C, so your temps are obviously not 'normal' for that measurement, regardless of what kind of cute case it's inside of. If it's a mobile, then the on-die thermal diode is monitored and that is inherently a higher reading than a 'case' temperature for the 'same' condition because the die is hotter than the case (internal thermal resistance from the die to case). If you're measuring DIE temperature then the maximum operating spec is 100C and above that the P4 should throttle it's speed back in an attempt to lower it's consumed power, hence lowering the temperature, with 125C being shutdown (average numbers as I didn't look up a 'P4 mobile 3.06 gig' specifically because there isn't enough variation between the versions to matter substantially). Even here, your number of 108C to 113C is above anything that could be considered 'normal'. If those numbers are real, it would suggest the DIE temp is what's being measured and that your processor is 'normally' in the over-temp throttle range (depending on how accurate the temp reading really is) and on the edge of thermal safety shutdown; which WOULD explain your observed symptoms. They are correct that mobiles (which I presume they're claiming their system is 'like') operate the CPU at higher temperatures (albeit not as much as one might think due to the spec being a DIE temp rather than CASE temp) than the typical desktop and it's also true, even though not talked about much, that the thermal design specs for systems of that 'type' are based on 'real applications' (Intel's terminology) and not continuous 100% loads (continuous 100% load may overload the heatsink and put it into throttle down), but there is no way, for even that "type of system," that it should have a processor temperature over 100C under 'normal' operation in a room temperature environment unless it's, put bluntly, improperly designed, or you've got it somehow placed in an environment above it's thermal specifications (like say if the SYSTEM spec is up to a room temperature of 30C and you've got it in a 40C environment, or you've blocked the cooling vents with something, or some other 'not normal' condition). And, under 'normal' conditions, it should certainly NEVER hit thermal shutdown (which I suspect is what causes your system 'instability'). Nor should it hit thermal shutdown even if you put a permanent 100% load on it either as the thermal solutions should be able to handle the heat from it's throttle down mode (with 100% load). It should simply operate at a lower effective speed. To quote the Intel spec sheet for 'mobile' (as in a notebook) processors. "... Analysis indicates that real applications are unlikely to cause the processor to consume the theoretical maximum power dissipation for sustained time periods. Intel recommends that complete thermal solution designs target the Thermal Design Power (TDP) indicated in Table 23. The Intel Thermal Monitor feature is designed to help protect the processor in the unlikely event that an application exceeds the TDP recommendation for a sustained period of time.... With a properly designed and characterized thermal solution, it is anticipated that the TCC would only be activated for very short periods of time when running the most power intensive applications. The processor performance impact due to these brief periods of TCC activation is expected to be so minor that it would not be detectable. An under-designed thermal solution that is not able to prevent excessive activation of the TCC in the anticipated ambient environment may cause a noticeable performance loss, and may affect the long-term reliability of the processor. In addition, a thermal solution that is significantly under designed may not be capable of cooling the processor even when the TCC is active continuously." The last description of a "significantly under designed" thermal solution sounds like what you've got. If your numbers are real, it looks as if it is unable to properly cool the processor under even normal conditions so that if a significant load occurs it's swamped even more and, sometimes, to the point of the processor's protective thermal shutdown. According to Sisoft Sandra, the CPU runs at 108-113'C during normal conditions an the top of the unit is hot to the touch. Can I rely on this software's reading? What do you mean by 'normal conditions'? I've also heard that a P4 powers down when it reaches are certain temp to prevent burn out - is there any software that can prove that this is happening? The P4 should throttle when the DIE temp, not case temp, reaches 100C and shutdown at 125C. All help will be appreciated as this system has been in for repair 3 times in 6 months and I'm thoroughly sick of it, and I want to look into the possibility of getting a refund if they cannot supply me with a stable system. Thanks in advance |

The maximum temp while under load for that CPU should be around 50C. (100C is the boiling point of water!) Quite subjective while you saying that. You have to take into account the room temperature. -- WebWalker |

Just to give you one more data point... My laptop (a Dell Inspiron 9100)
uses a desktop P4 CPU (3.0GHz, 800MHz bus). I haven't seen the temp over 65C. Clint "Nel" wrote in message ...
