I was looking for good 120mm case fans , with thermal sensor on wire . Finally select , GELID SILENT 12 TC . two of them http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=320334598114 As soon they come , i will make a local review . I have two Akasa with LED , but half LEDs had burn out, so time to upgrade , with better - modern - auto controlled ones . .
