    I just installed a new heatsink/fan and when I look in core temp cores 0 and 1 are 7 degrees higher than 2 and 3.

    What could be the cause of this? Improper thermal paste placement? I used arctic silver and applied just like they directed.

    The heatsink I'm using is a scythe ninja plus.


    Edit: under a full load it's 2/3 degrees between 0&1 and 2&3

    Edit: So like 30 mins in running with a full load

    4 instances of Prime95 and RTHDRIBL Maximized core 0 and 1 are at 61 degrees and 2 and 3 are at 59 degrees. Is this running hot, I haven't over clocked anything yet. Or is it because it's a new system and hasn't been broken in yet.

    I have 2 Q6600's at home, and measuring the temp with coretemp I get variations of 4 or 5 degrees on both systems.

    Thanks, this is my first build so I'm a little hesitant. I expecting flames to shoot out any minute.

    my Q6600 varies about 4 degrees from warmest to coolest, for me core 0 or 1 are the warmest and 2 is the coolest

    So I'm playing around with the overclock settings in the bios just bumping up the bus speed, The bios has a voltage and memory auto optimize function that I left on. I'm overclocked at 2.8Ghz my system seems stabl, but my cpu temperature is around 69 degrees under load. This is too high isn't it? What could be causing things to get so hot?

    Geforce 8600GT
    Ninja plus heat sink
    Antec p182

    I used arctic silver followed the directions and I made sure that the heat sink is firmly planted. I actually redid it a few times to make sure I got it right.

    4 CPUs crammed into the same area, the quads run warm

    im guessing that since there's only one fan on the heatsink attached to the side , that side receives more cooling then the other side, and thus making one half cooler then the other ,which would explain the additional few degree's on the other end. Its just a theory of course.

    Arctic Silver's break in time is 200 hours.

    Yea I just read that, I hope that their expected decrease of 2-5 degrees is true that would be awesome.

    It actually kind of interesting two cores will always be slighty higher than the other two. Sometime the higher pair is 0 and 1 sometimes it's 0 and 3. The important thing though is under a heavy load they are all within 3-4 degrees of each other I guess.

    I noticed something interesting though is I'm doing a stress test with prime95 on all four cores and I turn on RTHDRIBL in a maximized window the temp on all the cores goes down 2-3 degrees. Anyone ever experience anything like this?

    My only thought was maybe the fan on my vid card was kicking in and affecting things, but it's so small and it's location doesn't blow towards the heat sink at all it seems very unlikely that it would make a difference that large.

    k, purely for the test, if you would put the fan attached to the heatsink on the other side , does that instead make the other 2 cores the coolest and the other ones hot? If that would be so you could easily determine that its a single fan related issue. If possible adding another fan to the heatsink so you have 2 fans, might be a cooler solution.

    Something interesting happened. instead of core 0 and 1 being the hotter cores 0 and 3 were the otter pair and 1 and 2 were the cooler.

    If I'm not mistaken, you can put a fan on both sides of the heatsink, correct?

    I would put one on the opposite side, and have it blowing through the heatsink
    towards the rear of the case.

    But there is already a fan on the back of the case where the heat sink, and above too for that matter. Will adding another so close really make a difference?

    I'm order 3 of these,
    Scythe SY1225SL12H 120mm Case Fan - Retail

    2 for the front for intake and one for a spare.

    Those temp readings are meaningless. Wait for the break-in period.
    There are people with the same setup as yours with those temp readings at 3.4GHz, while yours is just at 3.0GHz.

    Is there any special protocol for breaking in. This will be day 3 of my new computer, should I unoverclock or anything?

    I'd say around 70 degrees, I'm not sure but I'm comfortable.

    My G0 stepping ranges about 5 degrees, although I did notice when I was OC'ing it the cores would vary. Example, 0 and 3 used to be 5 cooler at one point and now its reversed. I honestly think they are all the same temp but the reading is just off.

    These temps are at around 70F ambient with case open, Scythe Ninja Mini, and 100% load with [email protected] It does get about 3-5 degrees warmer with Prime95 running.
