What's Your Core Temp Spread

On Sandy Bridge build, (Asus WS Revolution, i7-2600k, Thermalright Silver Arrow, Shin Etsu 751, 8GB, CAS7 DDR3-1600).

I'm at 7C spread from lowest core temp to highest @ 4.8 Ghz & 1.408 volts

65-70-72-67

Will update w/ next step

More about what core temp spread
  1. Mine all read the same which is around 6C lower than room temp. None of the Athlons I have used (only 3) ever gave realistic core temps.
  2. 6-8c

    (sorry I didn't think it was relevent to post my voltage, case and memory cas latency, the question seemed pretty straight up. lol)
  3. I'll have to double check when I get home. I remember on air it was around 8-9C tops but I think it's much closer now that I'm watercooled.

    The poll is one thing but the thread was intended to have a secondary purpose .... I listed this info with the intention that it might shed some light on the spread that we are seeing. Questions I thot might be answered .....

    Does lower spreads correspond with lower voltages ?

    Is spread wider on HT CPU's ?

    Do higher memory speeds and lower CAS have an influence ?

    Does cooler / TIM have an influence ?

    What core is typically the highest ?

    For example, I really have a lot of confidence in the Megahalems mounting system being able to provide even pressure ..... not so much w/ the Silver Arrow.
  5. 4 to 6 degrees C

    Polishing the heatsink base lowered the temps by about 5 degrees (don't know about the spread before polishing)

    Core 1 is the highest
  6. 1.32V Vcore

    4.032ghz

    Prime95 small FFT: Cores: 60, 59, 56, 58 (SYSTIN 63, CPUTIN 63, AUXTIN 45) in HWMonitor (I don't know which sensors, specifically, those last 3 belong to)

    Spread: 4C

    Lapped i5 750 CPU, not lapped Apogee XTL with a Swiftech 220 rad.
  7. My X4 965 stays between 0 and 1c between cores no matter the voltages or speed...If you have a spread between cores I always thought that...that condition corresponds to uneven pressure across the HSF/CPU die, air gaps or thick TIM in the HSF/CPU interface...I could be wrong but...........every computer I have built so far that had this "spread" was easily fixed by reseating the HSF
  8. Q6600 at 3.6 GHz at 1.42 volts: 5C (61 - 66 C).
    Q9550 at 3.6 GHz at 1.38 volts: 3 C (58 - 61 ).
    E7500 at 4.1 GHz: 2 C.
