The fan on my heatsink was making a weird and annoying chattering noise at high rpm’s, so I replaced the fan with the really quiet Corsair AF120 Quiet Edition fan.
The new fan works almost as good temperature wise but it’s much quieter, which was my main reason for exchange. I’ll probably swap it over when the SP120 is back in stock.
