Evercool aluminum case fan 120mm dual bearing model?

Id say that they are 31db if you lower the voltage to the fan to 7V. At 12V these things move a ton of air and are probably closer to 35-38db range. If you have a good fan controller, these puppies can undervolt down to 4-5V and still provide an adequate 15-25cfm.

 
Thanks for the url, I bought my case from them at a good price. I did see some fans like these on ebay for 2.99 + 7.00 shipping or something but they had the multicolor led lights. Maybe I could just remove the lights?
 
Thanks for the info on the fans Tiamat, I guess there isn't much practical difference between their 1 and 2 bearing fans?

I don't suppose they make a fan controller that would let me switch between 4-12 volts, or is that just the function of the rheobus? on the controller?

What about something like this Zalman ZM-MFC1 Fan Controller. It has different options for fan voltage, but I was hoping to get something that has a card reader and some temperature monitoring?

I guess I want a 5.25" bay controller. Any suggestions on wattage with these controllers? I read that I could control the pump speed also with one of these controllers as long as the controller supports enough watts?

I read this at Directron..

"Also, tuning of your pump flow rates can be done with a rheobus. The rheobus needs to have at least a rating of 18W per channel. Just like fan control, if a user wants the lowest sound level possible, the pump voltage can be decreased. This can lead to different CPU temperatures and as a end user, you can control this! The sound levels have been greatly reduced. Remember, at least 6 Volts is needed to start the pump."

Is 18 watts per channel a good rating? Any suggestions? Thanks again guys.
 
Zalman goes down to 7V i believe. There 5.25" thingy that is. Their fanmate stuff goes down to 5V. I have a sunbeam rheobus 5.25" thing and it goes down to 0V. Obviously for most normal fans, my rheobus is somehwat useless (the 0V-5V range that is), but for special fans that can start up at less than 5-7V, its a jewel. I would not pay any more than 20$ for the sunbeam fan controller - or any fan controller for that matter.

Note: Fanmat takes 3pin connector, while evercool has 4 pin molex.
 
Right on, thanks for clearing that up for me. I think I know what to shoot for now.

It seems like using the larger fans on slower speeds can have equal or greater cooling power while making less noise than the smaller fans?

I would like to have a 4 fan controller with the rheobus that goes from 0-12v and that can handle upwards of 100watts through at least 1 channel(for pump), yeah I know, "forget about it" right?

A temp monitor and a rheobus control for my fans and pump would let me basically "tune" the system on the fly, that would be cool 🙂

So If I had 2 120mm fans on one radiator could I run both of them from 1 "channel" on my rheobus thing? Since they would both be doing the same thing they could always be at the same speed right?

The closest i have seen is my Sunbeam which allows 20W per channel. I do not know of a single fan that comes close to 20W. The Vantec Tornado is 12W or something? I dont remember. www.svc.com may have some in stock. If not, you can check frozencpu.

As long as the 2 120mm fans do not require more than 20W you can do it. I would probably cap it at 18W summed up though just to be safe.
