    Swapped out my Pentium D 3.46Ghz 955XE Extreme Edition for my Intel Core 2 Duo E6600 B1 Step 5 cpu to see how well the Scythe Infinity cools compared to other air and water cooling I tried.

    Cooling used:
    • stock Pentium D 2.8Ghz 920D heatsink + Sunon 80x25mm 49cfm fan
    • Thermaltake Big Typhoon + Thermaltake 120x25mm 81cfm fan
    • Scythe Infinity + 2x Thermaltake 120x25mm 81cfm push-pull
    • Corsair Hydrocool 200EX + Thermaltake Big Typhoon LGA775 mounting gear
    • Swiftech G4 Storm Water + Thermochill 120.3/MCP650 Pump

    A few notes:
    1. This is first time i have used my E6600 B1 cpu since i re-lapped the IHS, first lap was half ass job with alot of scratches but this time it's alot smoother and shiny.
    2. Please keep in mind other results were done at different room ambient temps compared to current Scythe Infinity tests.
    3. I'm using a different power supply, before it was either 700W OCZ GameXStream or 1KW PCP&C SLI psu. Now, I am using the new 850W OCZ GameXStream which has 4x +12v rails rated at 20 amps each - of which 2x +12v rails are for independent PCI-E connector power.
    4. I've figured out how to use Intel D975XBX Bad Axe's Intel Desktop Utilities (IDU) application which reports temps, vcore etc. It seems if at any time within a windows session you load cpuz, clockgen etc, you will cause IDU to freeze or hang. The only way for IDU to work properly is if within the windows session you don't load cpuz or clockgen if you intend to run IDU.
    5. Due to IDU issue and fact D975XBX Bad Axe board from bios only allows max 400fsb, it means for tests at >400fsb that require increasing fsb from clockgen, I will have to only use coretemp app to show temps and not use IDU.

    System:
    • Intel Core 2 Duo E6600 QPGE B1 Step 5 ES
    • Scythe Infinity + 2x Thermaltake 120x25mm 81cfm push-pull
    • Intel D975XBX Bad Axe rev304 1334 bios
    • 128MB Gainward FX5200 PCI card
    • 2x1GB Gskill PC6400PHU2 HZ Micron D9GMH 0629 batch
    • 3x 320GB Seagate 7200.10 SATAII hdds
    • Pioneer DVD-RW Burner
    • 1.44MB FDD
    • 850W OCZ GameXStream

    How does Scythe Infinity compare to other cpu cooling solutions I have used on the Intel D975XBX Bad Axe platform ?

    E6600 stock @2400Mhz at 1.275v (bios = 1.254v)

    Rise above ambient delta = CPU load temp - Room ambient

    Rise above windows idle delta = CPU load temp - Windows CPU idle temp

    Let's try my usual 24/7 clocks of 3600Mhz at 1.394v bios that I use on water, but on Scythe Infinity air now :)

    Room temp: ~28-31C
    Cooling used: Scythe Infinity + 2x Thermaltake 120x25mm 81cfm push-pull
    Bios idle: 54C
    Windows idle: 42C
    Windows load: 69-72C
    Rise above ambient delta = 41-44C
    Rise above windows idle delta = 27-30C

    That's around 6-12C hotter than when on water cooling.

    What about the Infinity with only one TT fan? :p

    So the Infinity is slightly more efficient than the Big Typhoon. I see :thumbup:

    Yup Scythe Infinity will beat out Big Typhoon when a decent fan with enough air pressure/cfm is used.

    i.e.

    1. Infinity with 2x TT 81cfm is about 0.5C to 2C better than Infinity with 1x TT 81cfm
    2. 1x TT 88cfm Infinity is around 3C better than my Big Typhoon with 190cfm 120x38mm delta fan for 955XE

    so Infinity with 2x TT 81cfm fans is around 3.5-5C better than Big Typhoon with delta 190cfm 120x38mm fan

    Update: 24hr dual stressprime orthos completed @3600Mhz at 1.388v vcore with Scythe Infinity air cooling. Here's post load idle temps :)

    How much does this combo cost and where from? Sounds like a winner.
    Speaking of sound, is it noisier or quiter than the BT w/120mm fan?

    For curiosities sake, how far could you push your e6600 with stock out of the box cooling?

    Cheers.

    scythe infinity i bought for $75 from www.pccasegear.com not sure of the fans i got them as freebies from www.mittoni.com.au (Thermaltake Aussie disty) :)

    The TT Smart case fan II http://www.mittoni.com.au/thermaltake-120mm-smart-case-fan-ii-p-1904.html probably closest to my fan i used with 93.7cfm vs my 81cfm and 4.1mmH20 air pressure vs my 4.71mmH20 air pressure fan

    if you mean scythe infinity with stock 46.5cfm fan vs big typhoon with stock 54cfm fan, then the scythe infinity stock fan is quieter than big typhoon stock 54cfm fan.

    my E6600 are engineering sample cpus and don't come with a stock intel heatsink so who knows heh.

    How about lower vcore and see how it does ? my E6600 B1 cpu has a default vcore of 1.275v bios (1.25v). I set vcore in bios at 1.3v (1.265-1.277v bios) and clocked E6600 to an easy 3406Mhz (9x378fsb) for dual stressprime 'orthos' testing with Scythe Infinity heatsink and 2x TT 120x25mm 81cfm fans push-pull configured. On water my E6600 did 3550Mhz on around stock vcore 1.25v bios so thought 3406Mhz at 1.265-1.277v would be a nice start for air cooling :)

    Only two changes were made to my system rig:
    1. I swapped from my 850W OCZ GameXStream (quad +12v rail 20amp/rail) psu to my 600W OCZ EvoStream modular (the first EvoStream psu in Australia :D )
    2. Removed one 320GB 7200.10 SATA hdd as i needed to use it for another purpose. So chanegd from 3x 320GB 7200.10 to 2x 320GB 7200.10 hdds :)

    Just amazing I must say for Scythe Infinity air cooling, E6600 @3505Mhz at 1.3125v bios (1.289v)

    E6600 @3505Mhz at 1.289v


    Room temp: ~24.0-26.5C
    Cooling used: Scythe Infinity + 2x Thermaltake 120x25mm 81cfm push-pull
    Bios idle: 44C
    Windows idle: 38C
    Windows load: 54-57C
    Rise above ambient delta = 28.5-33C
    Rise above windows idle delta = 16-19C

    All temps still based on coretemp readings.
