Is there any way to run a Tornado at slower speeds

[Agr3sive]

I bought a 92mm Tornado for my XP-90C and was wondering if there was any way to slow it down to kill some of the niose.
I didnt really understand just how load they are, dont get me wrong it has crazy performance, it dropped my P4 @4.2ghz temps from 40/65 to 30/40, pretty damn impressive but I can not hack that noise.
I thought the little fan header would be able to control speed but its just a reading device. So is there anyway to do it or am I going to have to buy a quieter fan, was looking at the YS-Tech 92mm 50cfm at 30db, is there any other good fans out there. Looking for big cfm and low noise.
Thanks

You could use anything that decreases voltage to the fan. I am not sure if tornadoes run at 5v, but you could always just swap pins on the molex that would be quick and easy, just remember not to use that molex for a disk driver EVER.

Other methods:
Resistor Soldered inline.
Fan Controller
Buy a cheap rheostat...

I have a fan controller but it dont work in there, went on the vantec site, says it just reads speed and not changes them, what pins would i need to change.
Have red and black at the fan, which colour wires from the molex would they need to be touching?

The cut wires and resolder the fans ground into a 5V line. That will give you 7V, less CFM and less noise.

I cut the negative and connected it to the 5v, its running nice now at 7v, a lot lot quiter and not too bad cooling

7 is the lowest you can go it wont start spinning at 5, well at least not mine, you can put it to 5 once it has started.

Both of mine ran fine at ~5v (4.77v actual).

I know use them with a CoolerMaster Aerogate I, had to cut the wires to do so. Not sure what it feeds them at lowest setting, my guess is ~7v. You can def still hear them, but it is SO much better now.

Just started my machine and it doesnt boot, unplugged the fan, it booted then plugged the fan back in, (works fine now). I also have the aerogate 2 if i wanted to use it on there, do i just cut the red/black and yellow to the same lenght and connect them into a fan header and plug it in?

connect it to one of those 3 pin fan controllers and then to another fan controller

Is there any problems running the fans @ 7 volts 24/7 ?
I have some case fans that i need to lower the speed on,but these p/c's will be on 24/7/365.25
My main concern is the power supply.

Thanks for any replies...I didn't want to make a new thread just for this question.The forum police would be after me calling me a NOOB :stick:

lol, dont worry, 7v should work fine with any psu afaik :)
24/7 365days a year :D

What new dBa and CFM did you get with the 92mm Tornado after modding it to 5/7v? Quite interested in getting ones of these and doing so if it reduces noise enough.

i got a fan controller from one of my gfx card thigns, the thermaltake giant 3, has hi med lo settings, i think its 12 7 5 or sumthin, but at low its really quiet, medium its noisy but tolerable

Because the XP-90 & XP-90C offset the fan,
a 92mm, 68CFM Panaflo cools just about as well as the Tornado & they are MUCH quietier. :toast:

Any Delta or Tornado fan I've ever had runs at 5v no problem. They are essentially the same fan and Delta rates their fans as low as 4v.
