    Default New Setup Overheating in Seconds with prime95

    Here's the Setup

    Antec 900 Two
    Corsair 750HX
    2x XFX 5770
    Gigabyte GA-P55-UD4P
    Intel Core i5-750
    Coolermaster RR-B10-212P-G1
    4x 2GB Crucial DDR3-1333
    2x WD Raptor 300GB
    2x WD Raptor 74GB

    Anyways, with that out of the way...

    Started doing some tests with prime95 64bit and I hit 99C in 20 seconds or so using the bone stock config. Happens even faster if I try to follow the overclocking guides from Tom's, MaximumPC or NCIX. I used Arctic Silver, and I've already re-seated the heatsink twice. Case has 4 fans, plus the one on the heatsink.

    Just doesn't make any sense. Please help a guy out......

    Welcome to PureOC! Let's see if we can help you. Forgive us if we overstate the obvious, we're just trying to be thorough......

    -do NOT overclock yet. Always make sure your system is running good for at least a few days before OCing.

    -not to insult your intelligence or experience, but you may be seating the cooler wrong even if you've redone it. Reason I say that is because the stock cooler is a PAIN IN THE ASS to get done tight and correct. I've done it COUNTLESS times and I still cuss like a sailor every single time I have to do a stock Intel cooler, believe me.

    A few questions:

    -what program are you using to test the temps?
    -can you post a screenshot?
    -what are your idle temps on all 4 cores?
    -are your BIOS settings to Auto? If not, put everything to Auto. We need to isolate the problem. No manual settings or overclocking


    My guess? Your CPU heatsink isn't heated correctly. Nothing else would cause this except a fubar'd CPU. Unless the temp readings are incorrect. Honestly, those are the only explanations I can see.

    Give us that info and we'll help you out. Might take a bit of time to go through things one at a time though. But a bit of patience will be rewarded. You don't want to blow out a new CPU.

    I'll get some screenshots. The cooler isn't the stock one, it's the coolermaster that I mentioned above the 212P.

    CoreTemp64 to measure temps

    Core Temps at idle with stock voltage and clock is around 40-41 on each of the cores. Seems really high

    I've tried the settings on all auto, and I've tried to gigabyte utility in windows to set it back to base clock settings too.

    Sorry, Cooler Master, my bad.

    40C at idle isn't too bad, but the HUGE jump at load is a big concern. I've had that happen before. It was because the heatsink wasn't mounted tightly against the CPU, there wasn't enough pressure so at idle it was ok but at load it jumped to over 90C within 10 seconds. Sounds familiar to you which makes me wonder.

    wanna hear what i did... with my new apogee xt waterblock i mounted it all excited at 3am and after starting it up i got temps 15 degrees worse. i was lying in bed tossing and turning and suddenly it hit me... id forgotten to take the clear plastic film off the block arrrrg what a fool. just that film made 20 degrees difference.
    so youve got everything on factory defaults. your fan is going full power? and youre getting 99 degrees with Prime? yes somethings not right. id say try RealTemp.. thats what i use. if it still says the same thing it has to be your coolers not working and if its at 100% it has to be the mounting. if its mounted correctly then it has to be your temp program. are you sure your putting the paste on right (pea blob then press hard and screw that sucker down!) and have you taken off that plastic film?

    Wow! "Pea blob?. I think I used almost a whole tube. Maybe that's the issue.

    oh yeah dood... the smallest thinnest most perfect layer possible with no bubbles. thats why i think that pea method is the best. if you spread it then push the block down i can definately see bubbles forming.
    for the diamond 7 compound it suggests a 5 millimeter sized pea blob. and it has to be screwed down really nice and tight obviously without cracking anything. the compound is just to fill in any imperfections in the two surface areas thats all. clean that off with rubbing alcohol and something not fuzzy to not get hairs. and if you do take the cpu off (maybe dont have to) DO NOT get any goop on the pins. i did once it didnt wreck it but it didnt boot up right and i had to carefully clean the pins off. and youre always touching the case every few minutes to discharge that electric shock? good luck and let us know how it went. glad i could help

    yes, thinner layer of paste work best than thicker layer.
    Thermal paste purpose is to fill the imperfect contact surfaces between cooler base and CPU heat speader. If you have it to thick then it works against its purpose.

    Hi hammonss, hi guys, I had the same problem with my new built system at first, most likely the heatsink is not properly placed over the CPU; i think I removed mine three times trying to find the right place. The Intel type pins are a real pain, believe me. On the other hand the thermal compound layer needs to be very thin like jayfunk said, otherwise the excess will actually overheat the CPU.

    I posted a full review of my new system here http://www.silentpcreview.com/forums...ic.php?t=57310 for anyone interested.

    I also run into a problem with temperature sensors displayed differently of different programs. Now the dilemma is what the real temperatures are on my board? Seems that EasyTune6 (Gigabyte utility) and HWMonitor report values with 10 C lower then RealTemp and CoreTemp. Which one is right...?
    Maybe you have a similar problem on your board? Just out of curiosity, hammonss, whith witch program did you measured the temps?

    Default solved temp readings

    I think i solved the temperature readings. It turned out that CoreTemp and RealTemp programs are reading sensors from CPU and EasyTune6 and HWMonitor are reading sensors from the motherboard. Of course the correct ones are CoreTemp and RealTemp. Looks like my system is not that cold I though it is...

    The final (RealTemp) temps reached with one hour of Prime95 are:
    Ambient temp = 25C
    Idle temp = 32 C
    Full load temp = 64 C

    Also, I lowered the memory voltage a little bit and the temperature in full load decreased with 2C on the second test to 62C. Memory was still fully stable, maybe I can try to lower it even more.
