Hi all,

I am looking for a cooler (plus fan) for a new workstation system based on two cocket C32 Opteron 4184 processors on a Tyan S8225AGM4NRF mainboard.

My requirements are:

  • The cooler should suit for socket C32, especially for the board given above.

  • The mainboard will be mounted in a E-ATX big tower case (Chieftec Mesh)

  • The fan should not be too small, i.e. I don't want to have one of these fast-running coolers which are typically used in servers.

    As the market for socket C32 coolers seems to be quite small, I would like to ask you for a recommendation. Perhaps other coolers (which have not been officially released for socket C32) might also fit?

    Up to now, I only found "Noctua NH-U9DO A3" and "Noctua NH-U12DO A3" which would fulfil the requirements. But I can't imagine that there are no further ones.

    Thank you very much in advance for any help!

    Kind regards,
    Steffen

    C32 uses the same heat sinks as socket F (1207). Currently I am using server heatsinks, so I can not answer your question for a non noisy heat sink.

    Use any good desktop AMD socket 754/939/AM2/AM2+/AM3/AM3+ heatsink if you want a quiet heatsink for C32. They are the same size but don't use bolts like the standard C32 heasinks do, they use a cam-lock clamp. You will need to use a heatsink mounting bracket to use these clamp-on heatsinks. Some C32 boards include them in the package, but TYAN does not include them. Get yourself a Socket 754, 939, or 940 heatsink mounting bracket for a few bucks from eBay and screw it down to your board's backplates and then install a normal AMD desktop heatsink. Sockets 754, 939, 940, C32, and most Socket F units have the exact same screw hole pattern (two holes 3.5" apart) for attaching a bolt-through heatsink or heatsink mounting bracket. AM2/AM2+/AM3/AM3+ use identical heatsinks as 754/939/940 but use a slightly different bracket with four holes (but also 3.5" apart end-to-end) rather than the two holes for 754/939/940/F/C32.

    If you want a specific recommendation for a heatsink I would recommend something like the Cooler Master Hyper212, Xigmatek HDT-S1283/S1284 or any other 120 mm tower type AMD desktop heatsink. Your case is large enough to fit those easily. Opteron 4184s are not particularly hot-running CPUs and you will can run very low-speed fans on a 120 mm tower heatsink to cool them quietly. Server heatsinks generally do suck, with the exception of the VERY expensive Noctua NH12DO-A3 and NH9DO-A3. Those Noctuas are "proper" Socket C32 heatsinks that bolt to the board but they cost $60-80 apiece and don't work any better than the $25-35 units listed above. Nobody who knows what they are doing uses a Noctua on a Socket C32 board.
