I have purchased an MSI K9N SLI Platinum motherboard. I also purchased a Noctua NH-U12F heatsink from Quietpc.com for use with the motherboard. The motherboard has an AM2 socket and the heatsink claims compatibility with AM2 sockets. However, these two items aren’t compatible. There are a series of resistors on the rear of the motherboard, underneath the CPU socket. Most of these fall into the square cut in the rear mounting plate of the heatsink. Two do not, so the rear plate rocks back and forth on the resistors. I didn’t try attaching the heatsink but the whole weight of the heatsink would have been pressing on the resistors and they would almost certainly have cracked and come away from the motherboard.
Interestingly, the stock heatsink rear mounting plate supplied with the board has an extra half cutout section to accommodate the problematic resistors. The squares in the centre of the back plates are exactly the same size though. I’m not familiar with the specification for AM2 sockets, so I don’t know if MSI have broken the specification by placing the resistors outside the square or whether it’s sloppy design from Noctua.
Either way, I’ve had to send the heatsink back and I’d welcome any comments recommending quiet heatsink models that are tried and tested with the above motherboard.Pin It
