I can't take this stupid vaccuum anymore, so I just bought a 80mm Enermax adjustable fan, an 60 to 80 mm fan converter, and a sunon 92mm fan for the back to replace the one that burned out a month ago. The new fan is rated at 32.5 db and pushes 39.5 CFM instead of 48 db and 37 CFM for the old delta. I've forgotten what it was like to have a quiet fan. To let you know how much I hate that noisy bugger, I'm looking more forward to this than my TI4400/8500 Ultra(if it IS announced at Cebit).
