My two htpc's cpu fans are too noisy for my tastes and would like to change out the coolers for a quiter one.
The AMD, is in a HTPC desktop case and could accomodate a wide cooler but not a very tall one.
The Intel system is mounted in an old VCR I modded and has plenty of room but a 120mm fan, like the hyper 212, might be too tall.
Neither case has a motherboard tray or access to change the stock mount unless I completely disassemble them and thats why I'm looking for quieter coolers that use the stock mounting. Neither one has heat issues, just noise.
