Hey all, I have an IC-7 mobo and a Northwood 3.0HT. I've been using mobo monitor to find out the temp, and its reading pretty high (53 idle, up to 69 under heavy load --oh and i have a nice OC hsf on it with arctic silver). I heard that abit boards are messed up with finding out the correct temps for northwoods, but does anyone know if this is true? Or have a solution? Thanks!
 
The bios reports my temps way high too

Everyone is tellin me that Abit has wacky sensors that are never really right... so I would just try to reseat your HSF and try not to worry about it too much
 
I always hear that too... Strikes me as odd though. Being such a popular motherboard company, you'd think they'd get it right, wouldn't you?
 
Shoot, well i guess i should just re-set the cmos restart temp for the processor way high :eek: maybe...80ish?
 
Well, it's simple thermal physics, if that's the way to put it. The motherboard sensors aren't accurate enough simply because they aren't in the correct position to accurately gauge the actual temperature. If you had some electronics tools, you could accurately find out. But basically, it's a simple rule with Abit motherboards (I own an IC-7 and 2.4C) that the readings are usually about 2-3 degrees Celsius off. It's nothing to worry about though. You will have to understand that your processor will be running at a higher multiplier than mine and the increase in thermal dissipation is part of the equation with the increase in performance.

Some IC7 boards are off by ~15C; and some by 2-5 C. I have two of them unfortunately; using the same processor and identical setup. One reports 65C load another 54C load. They are both wrong, because the third board an IS7 with the same setup reported load of 48C.

To make it funny; the same setup using P4P800 Deluxe returned 42C load temp. May be it is a good way to sell heatsinks and water cooling gears. The more they can confuse you ....... including hardware review sites, the more gears they could sell you. :D

I finally settled in using external temp probe; add 5-8C on top of the reading and screw the motherboard sensors. ;)
 
From a LegitReviews article I read earlier in the year, Intel puts two temperature sensors into their CPUs. One is the one that your mobo gets readings from, and the temperature reading is only a calculation based on these readings.

The other one in the processor is located elsewhere on the CPU, where the temps get much hotter than near the sensor the motherboard gets it from.

Abits also tend to over 'estimate' whereas Asus boards tend to underestimate the temperature.
 
that does seem a little on the warm side

I have an IC7-G with a 2.8C and it usually reads around 46 idle maybe 58 load

cooling is a Zalman 7000A Al-Cu and AS5
 
Good and honest article; I read that before. However, there is no good reason they (Abit) could not get an accurate BIOS update to correct the high temp reporting.

I don't want to drill a hole into the sink; hence, I add 5-8 C to the external probe.
 
In the end, temps don't really matter.

Does it run stable? If so then stop worrying ;)
 
FWIW - the system in my sig reports out ~46C idle, ~58C under serious load. That's the "highest" temperature reading reported; My guess is that's the reading on the thermal diode on the die itself.
