Odd temps question

[perdomot]

Got an e4400 running at 3Ghz with default voltage and have been using an older XP-90 HSF to cool it down to 46 degrees at idle with Coretemp as my thermometer. I just put in an Arctic Cooling Freezer 7 Pro HSF and the temps dropped only 3-4 degrees. Decided to reset the cpu back to its normal 2 Ghz speed and see if there was a difference in temps. Same temps as 3 Ghz. I'm starting to suspect that the mobo sensors are the problem. I can't tell what my +12V rail is and the fan sensors give outrageous RPMs in Speedfan. I'm using a Gigabyte P965-S3 mobo with was a good value but this is really bothering me. Is my new 43 degree idle temp a good one for my cpu at default voltage and the AC HSF? I'm thinking its too high and that the sensors are bad. Hope someone can advise.

Try using Everest Home 2.20 - seems to be the most accurate!

Everest doesn't give me a cpu temp, just fan speed. Anyway, coretemp is supposedly very accurate but these numbers don't make sense. I really think something is messed up with the sensors.

Also noticed that the NB is very hot to the touch and was wondering if this might affect CPU temp as its very close on my Gigabyte P965-S3 mobo

I see.

You don't believe your sensors, but you trust your fingers.

Alrighty then...

 

[perdomot]

I don't trust the sensors because of the difficulty in reading voltages and the fact that a 3 year old HSF gets the almost the same temps as a newer and popular HSF. I've checked reviews for the AC Pro and should have better temps.

Generic utilities like Speedfan, Everest, etc. won't necessarily read new technology correctly. Use the monitoring util that came with mobo.

.bh.

i might be wrong, but your problem might have something to do with case flow, xp 90 fan configuration and the A/C freezer pro is different, one is blow down, while freezer is blowing towards the back of the case, so now most probably there is not much air flow to cool the northbridge and the mosfet and since you mentioned now the north bridge is hot to touch, maybe try improving your case flow?

Frankly.....Speedfan is updated often enough that I trust it's readings at least as much as the board's own readings. But it pays to be more thorough with your test procedures if you are that concerned. How to?

Buy a hand-held non-contact temperature sensor, with an LCD read-out. Places like Harbor Freight in the USA have these things fairly cheap. You can easily check the exact temperature of most points in your computer. You can find out what that "system" temp is actually reading. You can't get the CPU die temp with this thing, but you can get a reading off the heatsink base, which is fairly close to the die temp. You can compare readings between different heatsinks....etc. I've had one for five years...and use it frequently. Your finger is no good judge of computer temperatures.
