psst psst.... just itchy wanna add

12v-5v SWITCH <- i did this for the fans in my case

12v-7v SWITCH

now can have high or low speed at a flip of a switch... no need open up casing and put the wire here or there bla bla bla

as for 13.5k rpm fan that allngap mentioned...i actually bought one of those from him... 40mm sunon screamers... serious bad ass fans. tried using it for my NB heatsink but it ended up vibrating my entire case

i say go for it man... do it....it seriously makes life hell of alot easier if u wanna have silent + performance coz u can choose either 1 at a flick of a switch

wait a minute.... do 24pins psu still have the -5v wire if it doesnt have the -5 rail???

you guys talking about this right??



my suggestion is to cut and use it to make the 12v/5v switch so that u can straight plug in ur fan into the headers without cutting the fan wires. i myself bought quite a few for this purpose... and i use it for my switch. so i dont need to cut my fan wires. and i can remove/ change my fans anytime i want. with the 12v/5v switch u can easily lower down ur fan speed without opening up ur case.

u can use the 3pin connectors for the fan....and of course u can also reuse the male molex right now u can get them in the bulk section HERE (same guy i got mine from - can be trusted )

@SkyDriver
setting it at 5v wont 'slightly' lower down the rpm...itll actually reduce it quite abit... imagine my 120mm delta ffb screamer can go to a bearable silent with 5v

@sHawTY
done the switch yet? use the multi connector like i said above if u gonna do it man
and remember to post a step by step pic of how to do it here

cant u just disable the fan control in the bios?? or set the temp setting to lower if u wan it to run full speed....

most mobos should be able to....even my cheapo MSI mobo in the office can do it...

this is sumthin like what happened when i tried it with a Delta FFB1212EHE (3.0A Fan). the VR started smoking man!!!

im guessing doing this without a proper board with other stuff (dunno exactly what) on them is not ideal unless its a low powered fan (im guessing sumthin below 1.0A??)

high powered ur definitely gonna be needing those circuit boards. although 1 thing to check is to make sure ur fan can run (AND start) at low voltages.... mebbe a minimum of 5v. coz if ur building a fan controller with the VRs ull be adjusting the voltage being fed to the fan...and too low ur fan will just end up stopping if it cant run at low voltages. but if ur building a PWM controller than no need to worry about the low voltage thingy as a PWM will be sending out 12v on pulses.. and ur just controlling the frequency of the pulses.

EDIT: forgot to mention that i made a switch instead of using VRs to control my fan speed...but all ull get is hi-low speed....

12v-5v SWITCH <- i did this for the fans (ALL fans including my Deltas) in my case

12v-7v SWITCH

agreed...

too technical already.... halfway thru ur paragraph i got so blur i could barely see the words

anyway...concentrate on ur exams first... then later screw around with the controller. all the best with exams dude

salute to me for wat??? salute to shah81 la....

he mentioned it before here...its just that i remembered what he said
