What is hot ?

As in, what 24/7 full load temp are you guys comfortable with? At what temp does it start affecting the life of the CPU. I think I am OK. I am running a P4 at stock speeds of 3.0ghz With a 947-U that has a 6000 rpm fan throttled back to about 4500. Idle temps are 28c and full load temps are 42c. I run 2 clients 24/7 so it is always at 42c. Is that too hot for constant duty? There are a couple of mods I have been considering..One is too shield the video card. The CPU fan is sucking all the hot air off of it and blowing it through the CPU. the other is, make a standoff or shroud for the CPU fan to try and eliminate the "deadzone" in the middle of the fan.
So what are some "Good" target temps? for both P4 and AMD. I have a buddy who is just getting his new AMD system up and running and would be interested in temps for that too.

Thanks guys !

Scott

    As long as the real temps is below 70C, modern cpu's will live almost forever.

    Right, the Intel 2.4 Northwood was speced to handle 55 C with a 24\7 constant run, and the HTs to a higher temp yet. My P4 runs at about 48 C with a stock HS and is quite comfortable with that temp. Under 50 C is decently COOL, 70 C will be quite stable for your P4.

    What temps am I COMFORTABLE with?
    <55*C max., preferably <50

    What temp does it start damaging the CPU? It depends on the CPU. Mobile CPUs can do >100*C without a problem. However, as a blanket statement, anything over 60*C is too hot.

    Cool !! ( pun intended )

    So running at a constant 42c on my p4 should be fine ..I am going to do the cooling mods anyway to see if I can reduce some of the fan speeds ( read noise levels )
    Does the 9800 AIW pro have embeded temp sensors ? If so, what can I monitor it with ?
    I am using the Coolermaster Aerogate2 as a fan controler, it has 4 thermalcouple leads. I have one of them affixed to the heatsink of the GPU right next to the core. It is running hotter than my CPU it is at 48c sitting at the desktop with no apps running.

    when ambient temps are cool as in the winter months I overclock higher with a 48c+ load ...when it warms up I turn back the oc about 100mhz and turn down the vcore from 1.95v to 1.85v and get a 42c+ load. During the warmer days while I'm at work the load temps will get to around 53c and that's when my client starts malfunctioning and killing wus so thats when I kick back to something cooler.

    There is no way of monitoring the temp. of a graphics card through software without resorting to a serial interface, as far as I know. There are some cards that offer hardware monitoring, but as a general rule, don't expect it. And I'm almost positive your Radeon doesn't have it.

    Anyhow, ATi and nVidia both allow their GPUs to run insanely hot. If I were you, I'd do something like this:

    I'm an anything below 50c man myself, but since I also have very sensitive ears, I opt for slower fan speeds and higher than I would like temps. At full load my 3200+ cruises between 65c and 75c, depending on the room temp.

    I've seen problems develop up over 55C, I try to stay below 50, if its over 50 its usually time to do something to improve the cooling.

    hehe, i just cleaned my case and hsf today, i was running 54 before cleaning, now cpu load temp dropped to 40, hehe, u can tell how much dust i cleaned out.

    Well, scott has figured out the key to getting people to read a thread... think about the title for a second, look at the number of views vs. replies, and then think about the title again...

    On older AMD machines htat used a diode under the CPU you really need to stay under 55C.
    On newer CPUs that measure internally you can run hotter. It is actually the same temp, you are just measuring differently.

    ;D

    Well i don't see how anyone could have missunderstood the title since it was posted in the cooling forum. Then again if it had been posted in the pub then it would have been a different story. But we already have a thread on that subject in the pub. But all threads end up in the hot :D threads section on the forum homepage. That's prolly how this thread got such attension.
