I got my hands on 4 of these
http://www.axiontech.com/prdt.php?item=70726
and I am afraid they are nawing on my 5V rails a bit to much they are 0.29 MA each, so I was thinking could I convert these to 12 V by use a y adapter on both pairs now I have 2 sets of Postive,negtive,ground/FM plug /line could I then plug in a 12 volt current to them link the pairs positive to negative together and then using the positive and negative that's left hook the 12 V current into that distributing the 12V current out so it wont harm the fans.
It "should work" but would I be better of doing this or just using a AC/DC adapter and plugging them up to it?

zippy, see if can get a power cord adapter that goes from the fan connector to the 5.25" power connector used for hard drives & rom drives. might have to move 1 wire over so that the fan gets 5v & not 12v but that is easy to do. the fan needs only 1.45 watts(5v x .29a = 1.45w) each so it should not naw on the 5v rail unless it is almost overloaded already then get a more powerful psu.

Its a Ultra 550 PSU X connect, I am nearing the limit tho 3HDDs,3DVD writers, 8800GT ,SATA/IDE PCI card I am just worrying to much but for the mid and lower brands I'd rather not tax the 5V to much.

currently all fans in pc's are 12v powered not 5v so are you certain those 2 fans not in your posted link are 5v & not 12v? look on the label either front or back of the fan as it will be printed for voltage & amperage.

Ya and all the 12V fans I have has last 6-15 months before having to be replaced, I got these as a low volt long lasting solution to my problem of fans dieing yearly.
I have run these for about 6 months before I decided to see if I can change what ti runs from, I guess a AC/DC line to the fans would be best after all.

that is nothing compared to what i have. i ran into a somewhat same problem as you in that my mother's used lcd monitor needed a 12v 36 watt power supply & the 1 that came with it was 16v which would have burnt out the monitor in a short period of time. i realized then i could tap off the computer's 12v so i took off a power connector from a rom drive & soldered the monitor's power cable to the 12v & ground pin of the connector. ran it thru the back in of the computer & it works wonderfully.

I ahve a few mobos layign about as well I am rather pissed my good abit Nforce Althon XP3000+ mobo wont boot windose anymore.....but the cheapo ECS one will..... have a gateway P4 1.4 soemthing..with *giggle* rambus ramm, nearly 1GB of it too, I think.
I have a Biostar mobo with a broken socket 7 clip, and 2 or 3 older XP class mobos, 133 or 100 ram speeds.
I need to sell im off in a lot on ebay...mabe it will even pay for shipping ><
----------------------
So I tried running 12volt thought the 2 pairs of 5V fans didn't sound like they were distributing the current right, so I got im on 5V rail again also on a zalman speed fan RPM reducer, I am testing to see if it dose not over heat.... they sound like they are reduced in speed with it on high, but I dunno if it can take 4 fans LOL.
