From: Gerry_uk on 17 Sep 2006 06:53 Hi, I'm experiencing problems with Intel Core 2 E6800 temperatures on my ASUS mainboard, but part of the problem is I don't even know if the values I'm seeing reported on screen are correct or not! I've created a quick web page with a screen shot and details here <http://www.xp20.dircon.co.uk/hardware/> Does these readings make sense? -- Gerry_uk

Well from what I understand the core 2 duo cpu's have an old style sensor diode under the integrated heat spreader (The BIOS uses that for temp measurement) and 2 digital sensors one above each core. It's not uncommon for the measurements taken from the diode and core sensors to vary. Intel also provide a utility to access the core sensors and apply some stress testing.

From: Phil on 17 Sep 2006 09:55 Looking at those temps, I'm inclined to think that the Probe II reading is not to be trusted. As for the CoteTemp readings, they're a bit high if those readings were taken at idle. I would re-check that the heatsink is properly mated to the motherboard, and making good contact with the CPU heatspreader. In any case, a good aftermarket cooler (with artic silver 5) is a much better cooling solution than the stock HSF. -phil "Fred" <bluser(a)gmail.com> wrote in message news:4n51k0F8li45U1(a)individual.net... > Gerry_uk wrote: >> Hi, >> >> I'm experiencing problems with Intel Core 2 E6800 temperatures on my >> ASUS mainboard, but part of the problem is I don't even know if the >> values I'm seeing reported on screen are correct or not! >> >> I've created a quick web page with a screen shot and details here >> >> <http://www.xp20.dircon.co.uk/hardware/> >> >> Does these readings make sense? > > Well from what I understand the core 2 duo cpu's have an old style sensor > diode under the integrated heat spreader (The BIOS uses that for temp > measurement) and 2 digital sensors one above each core. > It's not uncommon for the measurements taken from the diode and core > sensors to vary. > Intel also provide a utility to access the core sensors and apply some > stress testing. > Available for download here > http://anonforums.com/builds/TAT.zip > HTH >

This is the strange thing; the recent BIOS update I applied to this board states that it's purpose is to provide more accurate temparature readings. The old BIOS gave lower readings. > As for the CoteTemp readings, they're a bit high if those > readings were taken at idle. Yes it was Idle for two hours. > I would re-check that the heatsink is properly > mated to the motherboard, and making good contact with the CPU heatspreader. > In any case, a good aftermarket cooler (with artic silver 5) is a much > better cooling solution than the stock HSF. Yup, this is exactly what I tried to do and failed:( Here's the ASUS readings as I went along: Intel cooler, old ASUS BIOS [CPU 50 idle, 60 load] Intel cooler, new ASUS BIOS [CPU 55 idle, 65 load] Zalman cooler, new ASUS BIOS [CPU 61 idle, 62 load] I originally thought the problem was either the Intel cooler is no good or the thermal contact between CPU and heatsink was flawed. I took off the Intel cooler and the thermal compound was all squashed down BUT it had some small holes in it, as if there wasn't enough. I assumed this was the problem and got the Zalman cooler and the Actic Silver 5. I took out the whole MB, reseated the CPU, cleaned everything and let dry. Put quite a lot of Actic 5 on the CPU, bolted down the Zalman, then used a torch to look at the connection. Everything looks flat and some compound has squashed out the sides. I put everything back assuming it was all fixed now, and total disappointment as I see the idle temp is WORSE than before! I note the Zalman heatsink is COLD. Could it be the junction is still flawed? What I did next was disconnect the CPU fan and power up again. This time the heatsink became extremely hot, extremely quickly, so to me it seems the heat transfer _is_ occurring? I'm out of ideas:( -- Gerry_uk
