    So how is it, the more expensive mobos does have that right ?
    i agree with you.

    is there any explanation in gigabyte site about what is the safe temps of these motherboards

    P35 and P45 do not have NB Sensors, only a sensor in the PCB located close to the NB

    Yes the new X58 boards have NB Sensors. 50C is kind of warm for p35/45, you can do a few things if you like, I always redo the paste under the NB on my boards (You should use NON Conductive paste if you do this) or you could add a 40mm Fan to the NB and this would help as well

    What FSB are you running, and how much ram in what configuration? What MCH Core voltage are you using?

    The TDP of 22watts for the P45 is interesting and hence why a smallish heatsink (larger on the DDR3 versions of the board) is only required.

    Ya, smaller die size I think is why.

    The funny thing I think is the X58 is hotter by default, but I think this is partially due to the data it handles and the way Gigabyte remade the NB heatsinks. The cover on them of course is of no help, but the thickness of the heatsink itself is terrible for dispersing heat to the air. The older "Fin" type was much cooler for sure.

    I may have to rip off my heatpipes on my board it bothers me that much, thats bad

    Thanks for the answer Lsdmeasap.
    So the new X58 boards do have a NB sensor, do even the cheaper models have it to and can i see it listed somewhere, maybe on Giga's own site ?

    IMO all manufactures should absolutely list if/not the mobos have an NB Sensor!

    I honestly wouldn't worry about it Lsdme. GPU's are allowed to be run at 80 - 95C, CPU's to 70 - 80C or thereabouts depending on model.
    But like anything electronic (and i've worked on a huge variety over the years) it's all about (moreso these days) designing a cooling solution that is adequate for normal and constant operation of the silicon.

    When you calculate the type/area of the required heatsink needed for a particular setup, the calculation is based on the maximum temperature (for a given ambient) that you want to allow.
    No doubt Gigabyte or any of the motherboard manufacturers, state in their designs a maximum working temperature for say a particular model of Northbridge in the standard Intel case setup and at a reference ambient - Then they decide on what heatsink design/surface area etc is needed for the job.
    Theres no point in having say a larger mass Northbridge Heatsink to run the NB at say 45C rather than say 60C, if it makes no real odds to the life or operation of the nb silicon. All it would do, would be to make the board more expensive.
    I think you'd be surprised how hot regulators, transistors, power IC's etc are allowed to get in consumer and industrial electronics.
    It's only because Joe Public dabbles with PC's more than say consumer electronics, that "he's" aware of the temperatures of many things PC - but in general has no comparison. I often hear, "I can't keep my finger on x heatsink longer than 4 seconds" , which has got to be the most innaccurate way of checking temperatures going.

    I agree with your thoughts and knowledge there for sure. Hey, I use the finger test myself and suggest it but only as a simple manner of checking if things are for sure way to hot or not, but not to gauge actual temp.

    What I was trying to say (I mean complain about) was the fact that they now use a more solid heatsink (Not sure if that actual "Mass" is more, but overall thickness is what I mean) as compared to the older one with the very thin fins on it (With less overall mass). I think the new ones hold the heat in more in turn making the NB hotter then it would be had they used the older finned type heatsinks because they allow more heat to be easily dispersed into the airflow

    I would have to put a older type heatsink on X58 to see if my point is valid though, as the new heatsink may actually be better and the chipset itself may just be far hotter no matter which sink is on it, I am not sure? But I do tend to think my thinking is correct about the heat displacement to the air in my new vs old heatsink design thoughts.

    Lsdme,

    But say for argument sake you reduce your Northbridge maximum temperature from 60c to 45c, yet that affect has little (if anything) on the lifespan of the silicon/chip itself. What would be the point in modifying the board?

    If anything, you could add another stress point weight wise if you went say for a larger passive heatsink, or made things like accessing the graphics card/memory etc more difficult when the board is in situe.

    There is also the other angle of how long do people keep technology for? I can't see the point in going overboard in cooling solutions (unless you are going for high overclocks and/or quietness) when you might say only keep the board for say 3 years (or less). Enthusiasts don't seem to hang onto boards longer than say around 3 years - they tend to want to move onto the next best thing asap.

    LSD...

    Sorry to resurrect an old thread, but I came across this while searching for a guide that I've seen on the net in the past, and now simply cannot locate! There was a guide to probable actual temperature, based on how many 'half-seconds' you could keep an index, or pinky-finger on it (laughably, the scales are different), and I thought you might either have it, or know where I can locate it?

    Thanks in advance,

    Bill
