    New rig as follows:
    CPU: I5 3570K

    Mobo: Asus P8Z77- Deluxe

    Ram: 4 x 4 GB G.Skill Ripjaws DDR3 - 2133

    GPU: EVGA 680GTX 4gb

    PSU: Corsair HX850

    Storage: OCZ Vertex 4 SSD 512gb

    Case: Coolermaster HAF XM

    CPU Cooling: Asetek 570LX

    What temps should I be looking for with this CPU under water, and what range of OC should I be shooting for?

    Ambient temp is around 70F here, and P95 27.7 on stock everything Im hitting like 65C/70C/72C/72C.

    I know Ivybridges run a little hot but that seems a little bit warm for me for the cooling Im running?

    Any links for good info appreciated TY :)

    You are 70C on water with no overclock? Did you not apply any thermal paste?

    Hmm thats about the same temps i see on my 3570@4500 1,26v on air.

    OFC i applied TIM rofl....

    Ceramique2.

    As I said, I was concerned that those temps were too high, and I guess its confirmed now. :p

    Wow, yeah. Have you tried reseating the waterblock?

    Nah...gonna do that tonight though.

    Just not familiar with s1155 or ivybridge. I know ivy runs hot but wasnt sure what expected or normal temps were.

    Last computers I put together and overclocked were all s775 so im out of the loop by a few years....

    Well, for your notes, my Xigmatek Dark Knight with it's included 120mm fan and Nano Diamond TIM on my 3770K at stock clocks:

    Idle is roughly 21-25C each core
    100% load with IBT is around 52-77C each core

    Overclocked to 4.5:
    Idle is 22-26C per core
    IBT load is 76-87C per core

    I mostly run stock right now, as I've yet to encounter any game or program that actually needs my i7 to be faster than that.

    In a few summary notes for IB:
    - ~4.2 - 4.4 seems to be the average overclock with stock voltage/no offset
    - 4.5 and higher if you increase voltage/offset
    - Heat is the main problem with IB and you'll probably run into this before voltage
    - With no longterm figures for IB, there aren't a whole lot of safety and longevity (i.e., 24/7) for voltage information. 1.2 seems to be safe, I've seen a lot of people run 1.3 and 1.4 for daily use, but they hit temp problems since it starts to run really hot even good cooling

    With the IntelĀ® Core™ i5-3570K and the Corsair H100 I was hitting 82c on LinX at 4.2GHz with 1.2v.

    OP stock MB voltages may be slightly high.

    1,2v is probably enough voltage to get most i5-3570ks to 4.2-4.5GHZ.

    Key voltages to keep temps down are PLL, offsett, IO/VTT.

    Not sure why the MSI MB doesn't have LLC/Offset voltage so I don't need to mess with it but many motherboards use LLC/Offset voltage settings to maintain constant voltage under load which can heat up a cpu if too much is applied. I've seen this LLC/Offset voltage cause over clocking problems for some people when they have it too high and their cpu gets hot under load.

    On my MSI Z68 GD65 G3 I run my ram at 2400mhz which requires 1.05v on cpu IO voltage with CPU at 4.5GHZ. Other motherboards BIOS list the IO voltage as VTT. The CPU IO/VTT voltage is important for stabilizing memory.

    PLL voltage is also important for stabilizing CPU. I run mine at 1.65v with CPU at 4.5GHZ.

    I run 1.17v on my CPU voltage for 4.5GHZ.


    Each mother board is different in how it conducts electricity but from everything that I have seen on SB or IB the voltages that I have listed effect the stability and temperature of SB/IB the most.

    I have over clocked SB and IB with the same MB and IB is much more sensitive to voltage. My experience is that just a few slight difference in voltages on any of the key voltage settings that I have listed will effect stability and temperature of CPU.

    Thanks everyone for all of the info.

    Much appreciated.

    Reseated the CPU cooler and running about 10C cooler now, with a stable 4.3Ghz OC. Pretty poor OC at this point but I only played around for about 20 mins before I stopped.

    Alot of catching up to do with the new socket, new chipset, and new BIOS. Last time I overclocked was s775 :p

    Thanks again!
