The question might seem weird, but I'd like to power up a fan, with a 3 Pin Molex connection. This fan will not be used inside a computer, so is there any power supply thing that you can plug in the wall on one side, and that has a 3 pin molex connection on the other side?
Otherwise, is it possible to DIY a power supply just for this regular fan?
Thanks for any help, I didn't find anything when searching the forums...
My PC is in an isolation box. I want to get a second iso box, but they are very expensive, so I'm looking into a DIY solution. The first idea that came was to use 80mm or 120mm fan for ventilation. But you're right, a small ac fan might be ideal. Any link or manufacturer on the top of your head? Thanks!
Edit: I'm looking for a quiet fan... the Noiseblocker one linked above is at 18dB/A only.
I did a DIY solution for my Home theater system. Check out Coolerguys.com under their home theater/cabinet cooling section. They have an 110v AC to 12v DC converter. I'm using it to power 3 Scythe S-Flex 120mm fans. I used the chrome grill guards on each side of the fan and bolted them to the back of my cabinet. I used a dremmel to make the round fan holes. They also have AC power fans too. I had picked up 2 of them before I started but then decided I wanted more cooling and quieter fans. My AV cabinet is split into 2 sides, and each side has one shelf. I hole drilled 2 1/2 inch air ports in the bottom and used black desk grommets to mask the holes. I ended up using 5 fans total. The 3 Scythes are on the back of the cabinet (very quite too) and I used the 2 AC fans (moderate noise) and mounted them via screws underneath 2 of the shelves which I also dremmel out round wholes to match the fans. I have a Cable Co. supplied DVR (called a Moxi) which is very loud as it is always on and it produces a lot of heat. I had to leave the cabinet door open to let air into it. It was louder that way before the fans, now I can close the cabinet doors and can barely hear the DVR and the fans.
You might try to google " muffin fans ". I have one of the "old" 120 mm 120 Volt fans (same size as 12 V version, but more power). Mine is 14W and blows 110 cfm - Real, not like case fan adverts. Also noise, but newer model may be quieter.
I found this old post through a Google search and wanted to ask a follow up for anyone that might be able to assist. Basically, I took an old DC supply that used to power a pair of cheap pc speakers. Its 12V 500ma. I took a pc fan out of an older system I had which I believe is 12v .14a (140ma). Is there an issue of too much power here? I plugged it in and it seems to work fine but I don't want to cause a fire or for this to overheat.
