Looks like this is what will be used on the EPIA-M10000:- http://www.arkua.com.tw/proddetail.asp?linenumber=23. Listed as an ARKUA 309R-AW4B and significantly larger than the EPIA-M9000 HSF. The noise specs also look good compared to the 9000 HSF.
If anybody knows where to get these as a separate item please post the info here, they would be very useful as a replacement to the existing 9000 HSF.
