Thanks for the input!
I have a Antec True380 with the fan only connector.
If you were me, would you connect CPU fan and/or case fan to Antec's fan only or go with SpeedFan by plug into mobo?
Which will do a better job?
PS. I haven't try the fan only on the Antec but I will try both method later to see the result.
Go with the Antec fan only connectors. If you have several fans, it will do a better job of keeping everything quiet. Speedfan is good, but you really are limited to the fans you can connect to the mobo, usually the HSF plus one case fan. With the Antec, you can control more fans and more powerful fans than are supported by the mobo headers (limited to 360mA in most boards) and get the benefit of the PSU working in concert with all of your case fans.
