Genesis said:I just opened my 921. I wanted to replace the fans; they are way too loud.
80mm 12v 100mA 2pin power connector, INDEK Corp. CFM A series
60mm 12v 75mA 2pin power connector, ELINA FAN
I replaced the 80mm stock fan with a PC Power & Cooling ThermaSense. It is much quieter. Next weekend I will either replace the stock 60mm with a quieter 60mm, or try to fit another 80mm ThermaSense (it would be extremely tight). The ThermaSense (is identical to their Silencer, but has built-in thermostatic speed control). According to real tests (not manufacturer's claims) their is only one quieter 80mm fan on the market which I will be purchasing and testing. However, it does not have thermostatic control.
Posters were calling me brave when I opened it up at first. Well, you beat me!!
I quess you need to keep the old fans to reinstall in case you get a defective 921!!!
Of course the E* people would frown on your warranty violation!!!!!!!!!
