Question about swapping out the fan on my Antec PSU.

[Salvador]

Hello.

I have two choices here with swapping out the fan on my Antec power supply. I can use a 3 lead Vantec Stealth fan and snip the wires, then solder the Vantec fan on or I can bypass this and sneak the wire outside the power supply and run a fan off of one of the 4 pin molex power supply connecters.

If I snake the wire outside the power supply, I won't have any fan control and the fan will be running at full speed all the time. If I snip the wire, I should be able to get the fan control.

Which would you do and why? Is the fan control that important? When I had the rpm sensor hooked up to the mobo, it didn't seem that much different. The Adda high speed fan seemed to be loud both ways.

Also.. The Vantec fan has a red, black and yellow wires and the Adda that it would be replacing has a red, black and blue set of wires. My guess is that red is positive on both fans and black is negative. Is the blue wire on the Adda the rpm monitoring wire? Is the yellow wire on the Vantec the rpm monitoring wire? I would then have to splice the black to black, the red to red and the yellow to blue then. Correct? I just want to be sure.

TIA,

Sal

Nice guide to doing the mod at above site.

I used Panaflo L1A and just skipped the speed regulator by running the wires out and splicing to yellow and red for 12V all the time.

Hope this helps!

I just got done buttoning up my PS and pc. I went with the PC Power & Cooling Silencer fan because it's clearly quieter than the Vantec Stealth that I bought today. Because I didn't have the rpm sensor, I didn't splice the wires. I just ran the wire out the side and then plugged the 4 pin molex connector into a y-splitter and then into a molex connector on the PS for power. No splicing, so I can swap fans easily in the future. The "loud" high speed Adda is still in one piece in case anyone wants to buy it off of me.

The place I bought the Vantec fan from will not take this fan back, even though it's in perfectly new condition. They say that they will not return a fan because of loudness. They say that the db rating is published. I don't know who to be pissed at. The shop where I bought the fan or Vantec for lying about the loudness. If the PC Power & Cooling is 20 db, there is no way that the Vantec is 21 db.

I figured that the Silencer was most likely quieter than the Vantec Stealth when the Silencer was going full speed and the Vantec was at partial speed with the fan control on the PS, so I just skipped the Vantec and doing the splice job all together. Maybe running it at full speed will help keep it cooler? Who knows, all I know is that it's quiet now.

This mod is awesome. The pc is quiet like I had imagined it being when I chose my components and fans. It doesn't sound like a freaking refigurator any longer. I just hope that the 28 cfm that the Silencer is rated at is enough to keep the Antec 400w PS cool enough. It should because it's similar to the Panaflo L1a in power and a lot of people seem to have had success in keeping their PS alive with it.

Thanks again for the advice.

BTW.. Red and yellow are the positive and negative? Is the black the rpm sensing lead?

Normally the red is positive, black ground, yellow tach signal.

Normally the red is positive, black ground, yellow tach signal.

Thanks. In the case of the Adda high speed fan, the blue is the rpm "tach" lead.

Thanks for confirming that for me.
