What are stable temps for my CPU?

    Hey everyone,

    Just like to know what i can OC my CPU to, but leaving it stable. At the moment, it doesnt go over 30*C idle, and never over 45*C under load.

    Its a 3.0Ghz, Prescott CPU w/ stock cooler, 3 case fans (one blowing air directly @ it, and one blowing air from the side into it, one at the hard drives (far away) and an Arctic Cooler for my GPU)

    I once tried OC'ing it, i went from 3.0 to 3.2, then 3.2 to 3.4, then 3.4 to 3.6 and it crashed but this was using a windows utility, and i heard its better doing it from BIOS as it starts up with the comp.

    I can set the FSB values from 200 to 350; 240 is 3.6Ghz. Im just asking because i dont want to fry my CPU :p...and i know a value too high will :p

    Thanks in advanced :D

    Cheers :toast:

    Your memory is going to crap out well before your cpu... that is if you don't have a divider... and I think that is your problem atm... your ram can't handle the fsb speeds.

    70C+= No no.

    What is a divider? A heat spreader?

    Also, i know what temps are too high, its just i want to know what will be safe, as in, what temps will make it go to 70*.

    Thanks for the replies.

    the faster (more expensive) intel chips hit 90c as the norm out of the box.. they dont fry and for the money they cost they would have to run stable and live a long life.

    wow thats pretty hot :p

    So why did it crash when i went up to 3.6Ghz? It only hit like 45*C. Was it because it was in windows and not BIOS?

    Before making any OC attempt investing in a decent 3rd party cooler is a must to keep things as cool as possible.

    I dont really want to OC to the max i can...i just want to OC to a stable amount, that will not hurt my CPU at all :).

    Thanks for all the replies :)

    Well, depending in temps with a stock cooler I deffinately wouldn't aim higher than 3.6-3.8 tops.

    well silicon's melting point is 1414º C and boiling point 2355º C, but due to the thin layer and other things your CPU is made off, you shouldnt count on getting it that high... :D, aww jokes aside, and AMD CPU will melt at around 120-130º C but around 70 -90º C the silicon in the CPU will start producing some wird stuff that might crash your computer, and maybe damage the CPU.

    fast intel chips running 90c out of the box dont kinda go with the "maybe damage your cpu" thing thow..

    its not ideal but if expensive top end intel chips can live with it.. so can most i would imagine..

    trog

    ps.. and no "they were designed to run this hot" stuff.. they were designed for the opposite but the design just failed to produce the goods.. i think the bottom line here is that u might have to run a chip a few mhz slower at 90c then say at 50c.. but i think it will survive the higher temps if it has to..

    lol, well i shall try OC'ing as soon as i can get my comp working properly on CS: source :p...Btw, is there really much of a performance difference between something like 3.0 to 3.4 or 3.6?

    nope.. not a real life one.. only a cpu benchmark one.. but as long as u dont over do it there is nothing to lose.. no point in going right near the edge thow..

    there is no direct relationship between temps/coolers and clocks...

    fit a half decent cooler.. clock your chip up.. dont shove silly voltages thru it.. find its unstable speed.. knock a couple of hundred mhz off that unstable speed then run it at that speed all day..

    Pinchy,
    I am running a Pentium D 805 Oc'd to 3.8 Ghz and the max temp I've ever seen is 60 C. Idle temp is 44-45 C. I am using a Zalman 9500 Cooler. "http://www.newegg.com/Product/Product.asp?Item=N82E16835118223"

    I even pushed it to 4.0Ghz and it only go to 67 C, but I backed it down because I was worried. Hope this helps you out man. To see this fan installed: http://www.techpowerup.com/gallery/288
