    Houston, we've got a problem...

    Sabertooth 990FX rev2
    fx-8320@4.1
    hyper 212 evo

    well, this is a very strange thing....
    with the case in vertical (normal position) Coretemp on prime95 48C
    with the case in horizontal position Coretemp on prime95 90C + and safe reboot.

    one question... why?

    maybe it does not seat tight enough against cpu at "orizontal"

    cooler master centurion 532, but with the previous motherboard (M5A87) i've never had this problem.

    However, case or not, what's the difference between the two positions? 40C????? Seriously i don't understand, i'm testing my system for hours... uff...

    Crazy question- when you lay the case down are the board and cooler facing up or facing down?

    A heatpipe cooler won't work upside down and the system will overheat quick.....

    If you have it setup this way it will overheat....

    I had this happen with a video card. I think the wick inside the heatpipes isn't drawing the fluid back to the base properly.

    I'd contact support and try for an RMA.

    So when it is standing up normally it overheats?

    Definitely sounds like the heatsink isn't secured properly.

    Did you use the backplate that came with the motherboard or the one that came with the heatsink?

    When the computer is laying down try putting a little sideways pressure on the heatsink, in the same direction gravity would pull it down if it was standing up, and see if it moves and see if it affects temperatures.

    Just so you know, that isn't always the case. A lot of heatpipes have wicks in them that make them work independent of orientation. That is why video cards with heatpipe coolers work even though they are upside down when mounted in the case. It is only the really cheap heatpipe that have that issue.
    Norton says thanks.

    OK just checking- temps seemed too dramatic a change not to ask :eek:

    ^^^ +1 Try it with the stock heatsink if you still have it (will help prove if this is happening or not)

    @newtekie- valid point- Thx!

    Same temp as the other cooler or same temp regardless of cooler position?

    If it's the latter then that CM cooler is likely defective

    regardless of cooler position, 65C full prime95 at 4.1
    i understand about the CM but how can a piece of metal be defective?? the fan run fast and if it was defective horizontal or vertical... it should always be defective! Moreover with previous motherboard all was fine... uff...

    It sounds to me like that cooler perhaps doesn't have the wicks in the heatpipes, causing this problem? Does the manual say anything about orientation affecting its performance?

    One way or another it sounds like it should be replaced. Get a Noctua NH-D14 like I have. You won't be disappointed. :D
