P4 3.6 running at 98C..................
Have a serious problem with a new p5n32-sle se deluxe motherboard. The board
is lga775, and seems compatible with pretty much all the P4s of that socket. Tried two different processers, with two different stock fans, one processer is a P4 Extreme 3.73, and the other is a p4 prescott (524) 3.06, getting the massive temperature of 97 - 98C, it doesnt seem to change under load. I get that temperature from the bios, and also the asus windows utility, tried latest bios, no difference in temps. I have just installed a heatsink/fan that is secured by a bracket underneath and screws tight, it doesnt make any difference. The heatsink is barely warm to touch, there is no noticable heat underneath the board. I have made sure the application of the paste is very sparing, as it should be. XP seems to load and work fine, it benchmarks ok, it runs 3dmark and prime95 for as long as i run them... I do get what seems a slight pause occasionally, the cpu benchmarks within Sandra seem to be in line with similar processers. Is there anyway to accurately measure the internal temp of the CPU??

An obvious question is whether those temps are accurate, because they
are so high that the CPU would probalby be destroyed if they were real. Try the Intel Thermal Analysis Tool (TAT). There was a link in a posting in this newsgroup about 24 hours ago in a thread very much like yours (only core 2 duo). Gaz wrote: Have a serious problem with a new p5n32-sle se deluxe motherboard.

Gaz (originally posted in uk.comp.homebuilt, but none of the suggestions have improved the situation) The processor temperature is measured via a diode on the silicon die. The diode is connected to the hardware monitor. The trick is to find a program that knows how to read the hardware monitor properly. Asus Probe is one possible solution (and since there are a couple of versions on the Asus site, you have to be careful which one you use). Speedfan (almico.com) is another potential solution, with the problem there being, figuring out which temperature readout is which. Speedfan labels the channels "Temp1", "Temp2", "Temp3", and you have to guess at what you are reading. http://www.almico.com/forumsensors.php (check to see if your chip is here) http://www.almico.com/forummotherboards.php (hmmm. No P5N32...) I guess that leaves Asus Probe. Some people don't like the "ProbeII" version, but give it a try just to see what temperature value it sees. Uninstall any older version you might be using first. ftp://dlsvr02.asus.com/pub/ASUS/misc...obeII10305.zip In the old days, temperature conversion was done by measuring the voltage across the diode, and then software converted the voltage value, to a temperature. Recent hardware monitor chips, have a table lookup inside them, where they convert the reading, into a value in degrees C. One problem with the hardware monitor, is a thermal channel can either be in thermistor mode, or in diode mode (and the mode changes the lookup table). If the software program using the Hardware Monitor does not set the mode correctly, then erroneous values are the result. Each of the three temperature channels has to be set in diode or thermistor mode, as is appropriate for the kind of detector connected to the channel. You can also read the temperature while sitting in the BIOS. But you still don't know for certain, whether the BIOS is doing the temperature reading properly or not. Paul |
