Just got this awesome unit for my Case (Extraction), it's currently paired with a SilverStone FMC3XW (White) 120mm Dual ball bearing Case Fan + Controller

Have got it purring in XP @about 40% on idle using Speedfan.

Problem I have is I have nothing that will control it. Neither the Zalman Fanmate2 nor my current fan controller Akasa AK FC-03 Fan Controller Pro (OA-002-AK)
Have the legs to Tame this fan :) :-

Rated Voltage 12 Operating Range 7-113.2v Rated Current = 2A Rated Input Power 24W if i run without Speedfan Ie outside windows.

Ideally I'd like to add a fan control of the sort that ships with the silverstone that I could add to this 31/2" Modded Fan Bay 1st is 120 S/Stone in bottom of Case(Intake) 2nd is 80mm on Side Panel. I would then ditch the Akasa(looks pretty that's about it)

I've spent most of today searching for something suitable, this forum, reding the stickies appears to be the most knowledgeable place to help me.

I'm a total newbee when it comes to matching the requirements of the fan with the necessary control & it's more than a few years since I forgot what my physics teacher said

Have tried a forum search on Delta but could find no specs or suggested parts for a suitable fan controller.

When I reboot it's awsome :eek: :) , but the wife can't hear the TV & it frightens the cat's :D . Have got some extra memory I want to try Memtest with but daren't at the moment Hehe!!
So you can see my need for help :eek:

Thanks
 
I know no 24W+ fan controller that you could buy.
If you can play a bit, check sticky about DIY fan controllers, perhaps you might want to make one. If you choose proper parts, you can make one that will handle any power.
 
If you got your Delta at Sidewinder.com I would send your question to them They have the best support on the planet! Good luck.

Yes either that or PM Electron Chaser. Also :welcome: to the forums!!
 
:welcome:

called a toggle switch and 7v mod...most toggle switches will handle those deltas plus more...

can get a toogle switch at any automotive store...I personally use a 3 position NOS switch that I got from my local autozone for a few bucks that I use on my 92mm tornado...

I thought I heard my ears ringing. LOL

Supershanks,

Yes well normally I would I say go order one of these.

and wire it according to this

However since they are all out of stock now, and I am such a nice guy, and I just happen to have an extra one. PM me your address and I will send it out to you.

I would be remiss in my duties if I failed to help out a fellow hardcore Delta Fan user. :D


Oh yeah!!!

WELCOME TO THE FORUMS
 
THANKS A LOT GUYS - Sorry i'm going a bit mutton geoff ;)

Electron Chaser, That 15 Ohm, 15 Watt ceramic rheostat with the other link looks a good place to start, I'm on the eastern side of the pond so i'll try round here. b4 trying the autospares (great lateral thinking never thought of that) ;)

There's a 1st time for everything but if i'm going to build mod anything here i'll start small
check sticky about DIY fan controllers
is abit heavy, if I built it i'm not sure i'd have the confidence to slot it in my rig :D .

I browsed the Delta site earlier today & got a link to a uk tech rep might send him an e-mail tommorow.

Thanks again
 
I bought the same fans from sidewinder, but I also shelled out the dough on their 25w rheostat. It takes them down to about 7 volts which is a lot more bearable but still adjustable.
 
Hi Ven0m,
No article is great have read it acouple of times, it's a reflection of my ignorance, i need to brush up on my basic electricity terms to help my understanding. have always built my own PC's but that's component assembly & troubleshooting. Nearest i've been is selecting power supplies but bottom line there is basically Max Amps :burn:

Having found this site & seen the stickies & had a kip :D i'm starting to warm to the project of building my own, but that's a 2 edged sword - great learning for me but some real dumb newbee questions for you guys :rolleyes:

thanks :thup:
 
But I really wanted to know what to change in order to make it more user-friendly :)
I had not too nice situations explaining some programming-related stuff to people, realizing after some time that they have no slightest idea what I talk about. And that wasn't always fault of lack of knowledge of listeners, but sometimes I jsut cannot make myself clear enough.

If you had any questions or suggestions - just make me know or add them to thread :)
 
I found this link earlier Kelsey Park School Electronics Guide which is helping me bone up on electric principles. (Ven0m - might be useful for others following your stick ???)

Spent a few hours looking for UK based suppliers of suitable rheostats these seem about the closest:-
Vishay M10 15Ohm ??
or Ohmite Model E Ohmite Std Resistance Values Here the 15Ohm 12.5W Model E seems closest. Would appreciate feedback as to suitability please :)

E-Mailed Delta UK asking for recomendation & uk sourcing.

I'm beginning to think the best solution will be to build my own
Ven0m - Rheostats are usually not powerful enough to use them alone as fan controllers
seems to be proving correct. will decide following feedback from delta & above possible sources.

Another guide I found is CPEmma Fan Noise Solutions This may be useful as parts are Uk sourced.

Yet another question for you guys :eek: I've seen some warnings about plugging large fans into mobo headers. Ny Delta fans came OEM style no instructions etc., so at moment both are taking current via 3 pin lead from mobo header. Should I change this ??

The Yellow lead is the sensor that can be left in the mobo but the other leads should be connected to a molex. ??

Thanks again for your help so far. :thup:
 
Thanks for info; I've read that controllers guide

I'm surpised that your mobo can handle so powerful fans. I wouldn't plug them directly to mobo, but if they work... Just check if nothing gets overfheated. Dual fan connector usually works as you said - RPM sensor goes where it should go - to mob, while + and GND from fan go to +12 and GND lines on Molex. It seems to be the best to use ground near 12v rail, as some controllers use this rail.
 
I've got 1 Delta + Zalman CPU fan in mine & son has the other Delta on his XP-120 on his DFI LanParty NF4 SLI-DR that I just built for him, the Delta was recommended for the Xp-120 so we got an extra 1 for me :). I think to be on the safe side i'll switch them both out. Both are running fine although now i think about it my cpu is running about 2C higher than normal which with the Delta added even @40% should be better than airflow i had.

I liked the Temperature Control idea but think Positioning the Thermistor will be a bit of a compromise.

On the newbee side to Electrics just founfd this as well Lessons In Electric Circuits

Thanks 4 that confirmation :thup:
Cheers
 
Thanks massraptor,
Haven't seen it in the Uk though & unfortunately unlikely to seeing this
to buy System Maxx Fan Controller, Black your best deal at the best price right now. Hurry! Supplies are extremely limited during the liquidation sale.
@SeansPCWorls :shrug:


Cheers :thup:

I wouldn't risk it unplug those fans ASAP even if they are working for now. Those Deltas are much to power hungry to be running off a MB header. You shouldn't run any fan that draws more then 5 Watts off a MB header. They will blow that trace right off the MB and curl it up like a watch spring.
 
Hi Electron Chaser,

Thanks for that i'm about to go to bed so will turn it off then. Get some Molex/3pin adapters tommorow 4 both m/cs.

Consider myself fairly well clued up (apart from electronics :) ) and am a bit annoyed that supplier didn't include any literature about it, wonder how many others are doing this. Oh wll :bang head

Do you reckon any of the Uk sourced rheostats I linked are any good,

I recommend you get the 15 Ohm 25 Watt model. Allow me to explain why. The watt rating is how much power the rheostat is able to dissipate as heat.
If you have this fan and you are using a 15 Ohm rheostat to control it you will be able to drop it to 7 Volts with no problem and it will just purr like a kitten.

However we must remember that on startup this beast will draw up to 3 Amps so therefore we must consider 3 Amps to be our FLA (Full Load Amps) and if we are dropping it to 7 volts (Trust me, we are with 15 ohms) then we have 5 volts (12-7V) times 3 Amps which equals 15 watts of heat to dissipate through the rheostat.

While you should be able to get away with the 12.5 watt model, if you try to turn on the computer with the fan on it's lowest setting it may burn up the rheostat. Since the rheostat will be dissipating the full 15 watts at that point. The choice is of course up to you. I however tend to err on the side of caution.
 
I got the leads to run fans through molex & sensor to mobo header as
Delta.PNG

However fan just runs @ full speed. It does this on both rigs. The connectors are std Akasa 3 pin to 4 pin converter C-Cable-Adpt. I was able to use speedfan previously when delta was directly connected to mobo. Is there anything special needed that i've missed.

Couldn't locate Rheostat in Uk so am in process of building Fan controller
LM317 Tutorial
I'm using the LM338 rated up to 5 A. As I said earlier I'm a total newbee to this hopefully if this is successful I'll progress to building Ven0m's designs.
