    Default EP35C-DS3R is too HOT !!!!

    Hi,

    My mobo is running between 38-43 C at idle when ambient temp is around 18C.
    But when i'm playing game it reaches 48C. At this temp i can't touch the passive cooler of the motherboard more than 3 seconds.

    My case is very well.I tried to open case but nothing changed about temperatures.
    I wonder where is the temp sensor placed? Maybe it is next to gpu so it shows the temperature high?
    My graphic card is hd 4870.

    What can i do for it?

    The P35 chipset is a little hot, to tell you the truth, it's not a real value, it's the temperature of the motherboard's PCB itself, not the chipset.

    Grab a ventilator and make it blow inside your case, you'll see a dramatic reduction at your temps, and won't make your graphic card or CPU proportionaly cooler.

    What is PCB?

    Temps increased! NO WAY!

    My mobo, EP45-DS3R, stays about your exact temperature range! I just grab and ventilator and it goes down all the way to 31 degrees celsius.

    PCB = Printed Circuit Board, the sensor is for the motherboard, not the MCH itself, the MCH and ICH themselves i don't believe there's a temp sensor for them, even bios doesn't read temps from them.

    Maybe it didn't work because i placed the ventilator in front of air grill without removing side panel.

    So you say these temps are normal and nothing to worry about?

    Are you talking about the Gold coloured NorthBridge heatsink? If so, mine gets as hot as 52C, which I consider is absolutely OK. If anything, that is considered "Warm" in the world of electronics.
    Running the memory at a higher frequency and/or playing a 3d game usually increases the NB heatsink temperature.

    I have my NorthBridge heatsink monitored by one of the channels on a Zalman ZM-MFC2 and know it stays fairly stable.
    I would be more concerned if it was cool as that could indicate that the Heatsink wasn't making good thermal contact with the Core.

    Edit:-
    If you are using the Stock Intel Cooler (HSF), the fans proximity to the Northbridge Heatsink is as such to help keep it cool. If you are concerned though, you could alter the way the CPU fan works in the bios, presuming you are using the Stock Intel fan - and to have it on full speed continuously. ie not on Auto.

    yes i'm talking about that heatsink.
    thanks i'm now relaxed.i use easytune to control fan speed.

    e8500 overclocked at 3.80 and max temp is 58 under load.

    I'm using a Freezer 7 Pro from Arctic Cooling, and indeed make my motherboard temps a bit higher.
    Right now is at 43 degrees, when i was using the stock cooler, was around 37 degrees.

    But still nothing to worry about, but check at bios the smart fan value, it should be at disabled to make your fan run at full speed, the stock heatsink is not very good.

    There's 2 models from Intel heatsink, one of them comes with older Pentium D and Core 2 Quad 65nm like Q6600 and has a copper base and measures two inches.
    The other one comes with newer processors like Q9300, aluminum base and just one inch.

    Obviously the newer are worse performers, but when talking about stock speeds, they do a good job.

    Very True...
    But bear in mind they are usually shipped with the 45nm chips that generally have a lower TDP, hence less heat and therefore no need to have a huge heatsink, unless you do want silence or the scope for flexible overclocking.

    I found my Stock Intel HSF, which as you pointed out has very little height, say just over an inch on the heatsink itself, allows a modest overclock, in my case from 2.66Ghz (stock e8200) to 3.0Ghz.
    Also it's design (and height) allows very close air flow proximity to the NorthBridge too.

    I have a P45-DS3R and i have wondering about the Northbridge temp also, I guess that my mobo does not have any sensor to read the temp there, corect ?

    The temp I can see with HW Monitor shows the system temp over 50c under gaming, but it would ne nice with a sensor to the NB!

    So how is it, the more expensive mobos does have that right ?
