Before you consider buying new fans, you will need to verify the type of fan headers used. At least, the earlier TM NAS models use (as far as desktop users are concerned) "non-standard" or "industrial" headers. This means that replacement fans are not a direct fit and might need some conversion to fit the motherboard. Or, you might find (as I did) that some motherboards have both types of header although there is no guarantee that the "standard" headers will work.
