Those with P35 chipset motherboards......

[Burner27]

Just curious if my temps are 'normal'. My rig is in my sig and with an ambient temp of 68F my motherboard temp is between 35c-39c. Is that normal for a P35 chipset?


Not sure if this has any bearing.....

I upgraded from an e6600 to a Q6600. Could the added cores contribute to the mobo temp rising?


Thx

I don't know if changing to a quad-core CPU would make a difference, but there shouldn't be anything wrong with those temps.

EDIT: oh you were talking about mb temps..

My P35 motherboard temps are around 50C idle (vs. 30C idle CPU), but in my case the chipset is passively cooled and has little airflow.

Is your chipset actively cooled (i.e. a fan)?
What is the chipset cooler like (e.g. aluminum heatsink, heatpipes, etc.)?

Mine doesn't have any direct active cooling on it and it does have heatpipes. It appears to be copper.

My board has no heatpipes, and the chipset coolers are aluminum. It's stable up to 333 MHz (never tested further) on stock voltage. To my knowledge, I've never had a crash or BSOD related to my board's temps.

I think your temps are fine :thumbsup: -- maybe at >55C I would start to worry.

Quad-Core CPUs put out quite a bit of heat. To answer your question, seeing the system board temps rise a bit under these conditions is not too surprising. Passive and active cooling are only as effective as the air it's being fed, so if the CPU raises the air temperature around the NB, the NB temps will rise a little. I wouldn't doubt that the Q6600 hits the memory bus (NB) a little harder under load. Nothing to worry about IMO.

Thanks. I appreciate the insight!

i heard the P35 didnt have a temp probe on it. And the motherboard is reading the temps near the area and not the actual die, so taking nb temps was pointless....

Can someone verify?

This makes sense to me as I'm on water and the board gets little if any heat from my cpu. I'm OCed to 3.2 and the mobo temp is 35c and up.The faster I clock the higher it gets. I am currently using a silenx heatsink w/ fan. When I had the E6600 installed the temps were a bit lower.

I have a block I plan to install on this board soon as I get time. That should give a pretty good indication.

I have the ASUS P5K and my motherboard temp is idle at 35C and I didn't start overclocking yet, so I'm guessing thats an avg temp range

i heard the design for it didnt allow the temp probe to be on the die.

Thats why im wondering if it even has a purpose to take nb temp as long as you know you have good cooling on it.

Of course mine is watercooled, but i think a HR-05 would be more then enough on any NB for you to set it and forget it.

What program/option in the BIOS do you use to get the MB temperature? On my DS3L I haven't seen an option like that.

hence why i said.... i dont think the P35 has a native onboard ondie temp probe, and motherboards that did report it was using a probe off the board near it and not the die directly.

Same here, I was getting a little worried too

Last night I played w/ this a bit. Ran prime till the temps reached 45c [hot as it gets] w/ all my fans at lowest speeds, 4 120mm and 1 80mm in this box on control plus the psu and NB which is the silenx copper. I shut down prime and boosted the fans to top speed. The cpu and vid dropped to normal pretty quick but the NB temp stayed high for a very long time. That NB cooler is pretty good, and those of us that have played with air cooling know that air sinks will return to normal after running load in a heartbeat whereas water needs to cool all the water in the loop. I don't know where that temp is coming from but I'm pretty sure it ain't the NB.

Thanks for the extra deductve work, WoodButcher!

RAWR... which is why i said for the third time... the P35 doesnt have an ONDIE temp probe.

Hence why you should just get the best cooling for it possible and forget it.


The temps you get from NB doesnt mean jack if its not the onboard die. Sure you know how hot it gets around the core, but your core can possibly be LOWER then what the probe is reporting.


Now if someone would just double confirm what i heard about the the P35 missing the onboard die... This thread can be lead to rest. :\

 

[zorrt]

the P35-DS3P, I strongly believe the sensor is next to the South Bridge. Not sure if that applies to all the Gigabyte boards though.

Where did you hear it?

 

[Modelworks]

Mine stays around 29C.
Gigabyte P35-DS3L.
System is overclocked.

I did remove the heatsinks and replace the factory compound with some of my own.
It also in a Antec 900 case with plenty of airflow.

XS forums. During an arguement where people were asking if NB blocks were truely worth it.

Then a XIP came out and said were all smoking crack because the P35 has no onboard temp probe so any temps we took was absolute BS in rating to performance expecially on a waterblock where there bottom of the die can be WARMER then the TOP if your h2o system is very good.

This made some sense... because ive had cpu's where the mobo temps were higher then coretemp!

Example off my old E6600

MB CPU temp 53C!!!! Coretemp ahhh 37C!
