Thread: CPU temp abnormally high for set up?

    ok, just built my new rig. now the cpu temps i have are a bit questionable, not as to whether or not they're within the tolerances but if they are what they should be
    here's my setup
    Athlon Xp 2800+ Barton
    Asus A7N8X-Deluxe
    Thermaltake Volcano 11 (Xaser Edition)
    Artic Silver Ceramique
    Case airflow is roughly135cfm in and 110 out
    fans are located
    intake 1 and 2 are in the front
    intake 3 is in the side window blowing on the video card/pci slots

    exhausts are
    1 and 2 in the rear just below the power supply
    exhaust 3 is on the PSU blowing out (also another fan blowing air into the PSU)

    temps were taken with Asus PC Probe that came with the mobo
    CPU Temp 39C/102F that's with the V11+ all the way up (rated at 75 cfm on highest setting)
    mobo temp 20C/68F

    ambient temperature is 22.5C/72.5F

    does the cpu temp seem a little high, like i messed up the application of the thermal goo, or is it just me?

    thanks in advance
    edit: temps taken after running Hot CPU Tester Pro LE for 3 Hrs and Folding@home for 5Hrs

    If ya gettin' temps less than 20C above room temp under 100% CPU load then ya ain't doin' bad at all m8 and I wouldn't worry about anything under 50C.

    well, i can't stand having this volcano all the way up for just normal computing, so when i turn down the speed to about 50% the temps rise to 42C. i know the temps aren't anything to worry about now, but i do plan on overclocking later on so won't they then go up even more?

    Did you also check the HS for flatness? It might need to be lapped a little as well to achieve better contact and thermal transfer.

    You won't know how your temps will react until you O/C it. So try it and see how high they go after you lap and re-apply the artic silver just to make sure it is applied properly.

    Just a suggestion,

    yea, i printed the instructions and read them as i did it, i thought i did everything perfect, maybe i'll wait a few days for it to set them check temps. sincei run folding@home 24/7 i only deal in under load temps. i'll see how it goes

    Noise is not the only reason that I prefer the 7+ over the 11 as the 7+ rates in at 0.52 c/w while the 11 comes in at 0.55 c/w plus I save a few $'s as well.

    well, today i lapped the heatsink and reapplied the goo. good news, 37C under full load at 21C room temp with the volcano just over halfway. after i lapped and polished it, i found that there was some scoring over a part that covers the cpu core. i think this scoring is what's keeping me from those last few degrees. i tried sanding it all over again but couldn't seem to get them out :(
    oh well, i knocked roughly 5 degrees off my temps so i'm pretty happy.

    Glad to see it worked.
    Some people go buy something else. Others make sure the product they currently have is working as best it possibly can to make sure they are getting all out of it they can...
    A little elbow grease, and not going by the presumtion of :its new, it must be be flat and lapped properly~ isn't always right. I lap ALL of my heatsinks just to make sure it is right. THEN I don't have to wonder when my temps are a little high. I KNOW I already made sure everything is good under the hood and I can look elsewhere for reasons why...

    PS There are better thermal pastes out there. Going by the presumption that Artic Silver 3 is the best is WRONG. Just because a lot of people use it, isn't right.
    I personally use Cooler Master premium, by Shin Etsu. I read a review showing that it dropped temps by 4c lower than Artic Silver 3. That is quite a DROP in temps just due to thermal paste!
    This is of course after the 3 day "cure period".
    I have also done my own test and found out it is a lot better. It dropped temps on one of my system by 2c, which isn't much, and another by 6-7c. So it is different for all comps.
    It is a lot harder to work with than AS 3 as well. Its consistency is more like peanut butter.
    Just a little FYI.......
