Taming Deltas !!!!!

[DakTannon]

I just got 2 delta fans and they are excellent 150 cfm with a static pressure of 12.7 mmh2o at 4000 rpm and to make it even better they are 120mm x 25mm unlike most deltas which are 38mm thick so they fit any where a normal 120mm fan does and my fan controller supports 25w per channel and these fans are 17w so I can use my fan controller the only problem is my controller can only take them down to 50% to like 2000 rpm - 2200 rpm which isn't too bad but i'd like to lower them a bit more when I don't need the extra cooling I have a cheesy rosewill fan controller that will turn them down to like 1000 rpm and not only are they super quiet (no bearing noise at all) but they still move a lot of air the problem is they rosewill pci slot fan controller is too weak and start over heating in minutes so I was looking for a way to further slow them down with having to plug and unplug an in line resistors everytime maybe some kind of variable resistor or another fan controller that I can mount in a pci slot or I can mod to put somewhere else in my case cause I have used all my 5.25 bays

 

 

have any ideas or suggestions or have tried this before

 

btw I found this inline controller heard anything about it

Have you tried it with your motherboard? It's worth a shot before making a purchase that might be unnecessary.

ic'm kind of afraid  to i heard a lot of delta fans can kill motherdoard header because of their massive draw i mean these are 17w each, one is the same draw as all 6 of my rosewill 2200rpm fans combined i will reasearch my mother board and see if it can handle them btw it is an X79 asrock extreme 11

even if you slowed em down I imagine they'd still be loud as hell :s

Damn was that one sentence lol?

Don't try it on a motherboard mate, they do have a tendancy till kill a motherboard. My Abit board died to it.

If you want quite I would just recommended getting some slower quieter fans than trying to lower these down. But if you want to use them hook them up to 5v and see if theyll start if they will thats just about as slow as theyll get if their not PWM.

i have actually slowed them down  to 1000 rpm and they are completely silent only problem was that they started overheating the cheapie rosewill controller cause it couldn't handle the 17 watt draw
