Welcome to SPCR! The Enermax Enlobal bearing does seem to be pretty quiet -- if you search SPCR for "Enlobal" you find a fair number of references. Neil, thanks for the reply, I tried searching earlier but got nothing, I am just going to have to get used to the search engine. Also I have been readi...

Is there any chance that the Enermax Marathon, HERE , can be tested; looks interesting and it would be a good way of determining how much noise is produced by bearings.
