I was going to add a new thread but this one seems ideal. Unfortunatly I don't have an answer to your question but a question of my own regarding system temps.
I've just bought an ASUS P5W DH Deluxe (Don't buy an ANTEC power supply if you buy this board it doesn't work by the way!). When I installed the Probe software it reported a temp fluctuating between 46 degrees to 50 on the MB when idling. I've checked this in the BIOS and it'd shown there too.
It appears to be the intel ICH7R chip that causing the heat. Is this normal?
Any advice would be really appreciated.
There's just a lot of variability between boards on temp readings. I really believe some board manufacturers artifically suppress the readings so people feel better about their rigs. My Pentium D 805 shows as my coolest running Pentium, even overclocked - I don't really believe that's true! But that's what my readings say.
Your difference really isn't all that great and I would say within the error margins for measuring these temps. I really wouldn't consider one better than the other.
That's interesting; Having 2 identical CPU on two different boards gives different reading.
1) Try downloading PC Wizard 2006 and use the temp. Monitor.
2) Is the thermal compound uses on both CPUs are the same?
3) Compare how much RPM on both fans.
4) Compare CPU voltage between the two.
5) Maybe a bios update on both boards will give you solution.
6) Base on my experience sometimes power supply can cause the hardware to increases the temperature. Unless the motherboard capacitor has a defect on them, or maybe just the temp sensor.
If all of the above mention does not fix the situation then wait till someone has more advice, or call ASUS and ask for more info.
If you can find another away to test the CPU temperature and not the board sensor that might help you narrow the issue. From what I know the difference between two CPUs on different board would be around 1 degree. Depending on CPU loads of course.
I was going to mention the Heatsink and Fan on my post but I recon that if he put the system together he would have known about it. I didn’t know about LGA-775 socket issue though.
Thanks SupremeLaw something I learned from this post.
