Reliable Temp Readings!?

[Kill-Switch]

How reliable, and accurate, are the temperature sensors on the Asus A7V333 motherboard?

I am VERY worried at the moment about my temps and can't understand what's going on ... I'll explain.

Until recently I ran my rig (see sig) and the two sensor readings were at (sensor 1) 62 and (sensor 2) 72 degress. The first is the sensor located near the processor (not sure where, but it's the one most people use I guess), the second apparently is the sensor on (or right under) the processor.

Well I removed my HSF only to realise I would have to put it back on (long story). So I cleaned the thermalpad crap off of the HS and hte processor and applied to Arctic Silver III before putting the HSF back on the processor.

Now when I start my rig I run MBM and sensor 2 reads about 78 from the start, but sensor 1 is at a more believable 45(ish). The temps rise (obviously) and sit anywhere beween (sensor 1) 62 - 66, (sensor 2) 74 - 82!!

Right now my rig is running with temps at 62 and 83!!

I've checked (and rechecked) to make sure the HSF is sitting nice and flat on the processor, and it is. The only thing I can think off is I used to have 2 80mm intake fans, these have been replaced with a 120mm intake fan. Surely that isn't the reason my temps are higher ... and come on sensor 2 reading 78 just from booting up the system!!

Asus temps are notoriously high. Get yourself a seperate thermal probe to know for sure.

This is very true. Asus always seem to report 8-12c higher than most other brands.

How many total sensors can you get temps from? One of those higher readings is obviously the CPU. Under full load 62c would seem right with a run of the mill HSF unit.

However, I would expect to see a system temp in the 25 to 45 range. Niether of the above temps look like a system temp at all.

Take another look in MBM and try every sensor choice to be sure.

Getting a probe like P0 suggested is a good idea too.

Ohh, not that high. There's a new version of Asus Probe out, BTW. 2.19.xx, see if you can get it. It showed more accurate readings, compared to 2.15.xx.

Anywho, if you're applying AS3 to the HSF you're doing it wrong. Put a paper-thin application of the stuff over the processor core, and rub some into the base of the HSF. This will help fill in gaps, and is a lot easier than lapping.

If you're using the stock HSF, that'd be another reason for high temps. What processor are you running?

BTW, I, too, have the A7V333, rev 1.02.

I can get readings from 4 different sensors and I have identified them as:

Sensor 1 - Motherboard
Sensor 2 - CPU (standard)
Sensor 3 - Case
Sensor 4 - CPU (core I think)

The temps I listed earlier were for sensors 2 (62) and 4 (83) and my system was fully loaded at the time (with F@H). I have disabled F@H and my system now sits at 60 and 74 (reading from MBM). I have only ever seen temps as low as 45 degrees when I first turn my rig on, and within 5 minutes it's up to 60 LOL

Right now I have no cash, spent it all on getting my watercooling stuff ... which is all preped to go just beed two damn barbed connectors for the waterblock.

Thanks for the headsup, I'll go get the new version of Asus Probe ... which FYI is reading the same temps as MBM (well MB and CPU temps).

I applied the AS3 as directed on the AS website .. placed a blob on the HS and took a bit off and applied a paper thin-layer to the processor core. The excess on the HS was rubbed in to fill microscopic pits :) ... So I got that right hehe.

I'm running an Athlon XP2100+ using a basic Coolermaster HSF combo. I bought an OEM processor and quickly bought a cheap HSF to cool it until I could get my watercooling system (which took longer than anticipated LOL). So yeah that could be the reason I have high temps .... BUT before I took the HSF off I was getting constant 62/72 temps fully loaded, which are high I know LOL

My 2100+ pally OCed to 1833MHz only hits 56C full load with a CoolerMaster HHC-001.

Eh, If it's just short term I wouldn't worry about it.

Well my XP2100+ is running at stock speeds and has been running for about 6 months (or longer) with the HSF it currentlt has .... I ony recently started monitoring temps because I was due to get my watercooling stuff and I was having a go at OCing the processor. So chances are it's been running at these temps or similar for a lon time now LOL

[Kill-Switch]

I think I may have finally figured where my problem was LOL.

To cut the story short I discovered that I'd attached my rear exhaust fans the wrong way so they were acting as intakes Doh!!

My system is running now and it appears to have settled at around 61 and 82 (give or take a degree) fully loaded. So it's not too bad, although the internal core reading 82 when before it only every reached 72 is a little strange.

I suppose this temp difference could be related to the fact I now have a 120mm intake (which is attached to a BIX) instead of the 2 80mm intakes ... and there is the Eheim pump sitting in the case causing airflow problems no doubt.
