    I've got 2 machines that both run on ASUS mobos.

    The one with the Phenom II 965 is on a M3A79-T Deluxe.

    The 1090T is running on a M4A89GTD PRO/USB3

    Both are OCed at 4Ghz and using 1.48-1.50 on Vcore.

    Both have the same identical aircoolers which are ZeroTherm BTF90's

    Both are in large cases with 5+ fans for air circulation..

    Cool and Quite is disabled in the BIOS on both and are set to High Performance in Power Options in Windows 7 64-bit.

    The 1090T OCed at 4Ghz with a Vcore of 1.5 idles at 29-30C and when under load reaches a maximum of 53C.

    The 965 OCed at 4Ghz with Vcore of 1.5 idles at 52-53C and when under load reaches about 69C.

    Heatsinks both have been triple checked and can be interchanged with the same results. Using Artic Silver 7 for thermal paste on both.

    I'm totally confused that a Hexacore OCed at 4Ghz runs way cooler than a Phenom II 965.

    Is this normal??

    I've got great heat transfer into the heatsinks.. The top of each heatsink is warm to the touch which tells me that the heat is being pulled away from the CPUs.. I just can't understand why the 965 would be running so much hotter with 2 less cores..

    Run WinPrime on both for an hour and the 1090T barely gets over 55C. The 965 is cooking at 69-70C..

    Should I be concerned?

    Maybe it's just the way the cores were built. Remember, the 965 uses the C3 revision and the Thubans uses the E0 revision. Could be some type of new process AMD used when designing Thubans that cause them to be cooler than Deneb.

    Remember, Thubans also support that shutting 3 cores down and OC 3 cores thing.

    your voltage is a little bit high imo. i have my X6 at 1.42v @4.0ghz. delatux may have a point about it being a thing with the cores. try backing your volts down on the 965 to like 1.4v - 1.45v somewhere in that area and see what happends

    results may vary. 1.5 for 4ghz is perfectly ok with both a 965 and a 1090t.

    what revision is the 965be? the c2 revision ran hotter and used more power.

    also, 1090t doesnt have a physical temperature sensor. it 'guesstimates' the temp based on voltage and load, etc. for an accurate temperature reading, use your motherboard's TMPIN1/TMPIN2 sensors. normally its 10-12C higher than what the programs are reading the core temp as.

    but yeah, for the most part, the 1090t runs cooler. my old 965be struggled at 3.8ghz to stay under 50C. my 1090t handles 4ghz at 42C effortlessly.

    I tend to agree with this, each individual processor is its own beast.

    My 965 can hit 4.0GHz at 1.48v,idles at 44-46c,max loads at 55-62c,using a Thermaltake Frio cooler,can even even hit 4.2GHz at 1.50v but max loads hits 69c,is this normal?It rock solid at 4.0Ghz.

    i just want to know why u bothered to build a 1090T system when u already had a 965 which is fine for now unless u plan to sell it to someone else or give it to someone

    Probably for video editing/large file transfers/CAD/heavy multitasking, etc...

    the 965 is in the Living Room hooked up to a 40" panel via HDMI and is used to play movies, music, and the occasional game like Medal of Honor or oneof the COD series..

    the 1090T is in the computer room and is used to bring down small governments and destroy the too big to fail banking establishments.. :flip2:
