    CPU Temperature.

    Hey peeps, if this is the wrong place then point me in the right direction, thanks .

    I've been folding now for around 7 months, i noticed about every month my CPU load temperature has gone up around 1 or 2 oC. It used to be around 55oC at first, but now it's getting to around 65oC. When i first built my computer i didn't use any of that stuff for the heatsink fan (to help the conduction of heat) forgot the name of it. Anyway, is it too late to get some? and what do you recomend to get it cooler? i'm going to brush out the dust later as i know that can heat things up quite a bit, do you think folding is damaging my CPU?


    Thanks

    What CPU? If it's an Athlon 64 it's very hot. You want some heatsink compound like Arctic Silver on there ASAP, it isn't too late!

    Do you mean F@H? What position are you at? I just got into the top 10,000. OoohYah!

    XPs are OK up to 80-90C I think.
    (My XP2400 runs at 60-65 under F@H load.)

    God really?

    I set my motherboard alarm to 75C, just incase if it does get too high.

    Most XPs are ratted for 85C on-die, most A64s are ratted higher.

    The key here is on-die. Most motherboards report 20-25C lower than on-die (this is called tCASE on A64s).

    I think A64s are mostly lower.
    Athlon thermal design guide lists T(die) Max value= 85 or 90C
    Athlon 64 ID guide shows my A64 3500+ Winchester (ADA3500DIK4BI) as max. Temp. 65°C

    Very true. Best to be on the safe side.
    Luckily the A64 has an on-chip thermal sensor, so should give more accurate readings.
    Despite this, I have the following under load (F@H):
    Room air temp 19C
    XP 2400+ CPU reading: 61C
    A64 3500+ CPU reading: 39C
    I've had the 2400+ for ages, it has definitely been run as high as 65C. That system is 100% stable.

    Desktop A64s list tCASE, the max heatspreader temp, wich is 65C for more recent chips and 70C for the older ones. If you look at mobile A64s they list the max on-die temp with is 90 or 95C depending on model.

    The only difference between most mobile A64s and the desktop A64s is the presence of a heatspreader. tCASE is listed as 25C lower than on-die and this is what desktop boards are supposed be calibrated to report. A64s do have an on-die temp sensor, but the BIOS still controls what temperature is displayed. This can be calibrated however the mobo maker likes.

    I have seen idle and load temp differences of more than 30C across various motherbaords I have used, with the exact same chip at the exact same speed, the exact same voltage and the exact same heatsink. They boards where calibrated differently. My soyo read 84C at full load, my chaintech read 72C, my Aopen read 69C, and my DFI reads 55C.

    Back to the point tho, if you haven't tinkered with that system in over a year it could definitely benefit from cleaning the heatsink (they fill up with dust quickly) and replacing or using a thermal compound of some sort.

    Its getting into the summer months therefore a higher ambient temperature will definately account for a minor couple of degress increase.

    Is it true Presscot core processor quite hot? Under normal condition with original HSF. Is it alright this processor run 70 degrees and above?

    It won't harm the processor, but prescotts start throttling at 70C, so you won't be getting the most out of the chip if it is hot.

    70C will not harm the processor immediately but with time it will affect the useful life of it. There's a very simple method to find out if your CPU is running too hot. No matter whether you overclock or not, no matter what cooling method you use, if you cannot hold your finger on the heatsink or block without getting burned then it's too hot for 24/7 use. Simple as that. Your HS should be warm to almost cold to the touch if it is cooling the CPU properly. Be sure you use a proper amount of thermal paste as well though because if you don't this method won't tell you anything.
