Hey Rory7,
It's cool to have some british amongst us
I didn't think there were any
....Well anyways, I have 2 Vantec Tornadoes and they make an incredible amount of noise but they're worth it. If you put your behind one you'll get blown away. haha............anyways you have a real nice system. But I dont understand why you need a tornado because the 9600XT keeps very cool, i've heard, a P4 2.66 shouldn't get too hot (unless you overclock). What's making the heat?
Well anyways the TORDADO is sweeeet, but unless it's compulsary dont get it.
The Vantec Stealth however is brilliant. An 80mm will give you 27cfm with only 21db!! The 120mm gives you a huge 53cfm for only 28db..hahaaaa. I think you can understand i like the stealth series.
Next, i highly recommend the vantec thermoflow's. I wanna get one. They're temperature controlled. Their lowest cfm's and db's are as loud and as good as the stealth's AND they go up to (quite a bit below) the tornado. In other words they are specified as being the fans netween the stealth and tornado. (Brilliant) Here is the Spec:
For the 80mm:
1950 ~ 3400RPM _
23.8 ~ 41.6 CFM
25.5 ~ 37.5 dB(A)
For the 120mm:
1300 ~ 2200RPM _
54.3 ~ 92 CFM
29 ~ 39 dB(A)
(pretty cool huh :grinthumb )
PS: You get used to the noise of the TORNADO!!!!
PS2: I hope you have some 80mm or 120mm case fan spaces.
PS3: I hope this helps!
PS4: I type too much
