PSU fan replacement?

post #1 of 13
Thread Starter 
Hello fellow OCNers!

So I put water cooling into my rig and it runs amazingly. The only noise in my case is coming from my PSU. It is an OCZ 1010w. It performs nicely and does not appear to run hot. You can't feel any heat when you put your hand on it.
My question is, do you think it is ok to put a lower rpm fan in it. I havent taken it apart or look at schematics on how it is built yet. Im wondering if the fan is hardwired into the psu or if it is pretty standard for high output psu's to have swapable fans incase the fan fails and you don't have to buy a new psu. I just spent $800 on water cooling so I don't feel like paying $250-300 to get a silent one. Does anyone have any exp taking psu's apart and is it worth it? Im annoyed with it since my case would be about silent if it wasn't for this fan. Thanks in advance!

i know some of the fans that i've seen in psu are a complete pain in the butt to replace and I definitely wouldn't replace them with a weaker fan. i don't think it's worth it to take the psu apart.

The fan itself is probably standard, but it's hard to tell if it's going to be soldered to the PSU or easily removable. It likely is just a 2 or 3-pin connector like you would find on your motherboard.
It's no big deal opening up a PSU, but it will void its warranty.
You may also want to be careful, as some components within a PSU can hold a deadly electrical charge even when not connected to a power outlet.

I can't stress this enough. I accidentally discharged an Earthwatts 500w with my thumb, right on one of the main capacitors. I experienced chest pain and shortness of breath for about a full minute. It was very scary. I am not joking when I say it is possible to die from discharging a large power supply.

Wow thanks a lot guys for your concern. That is very nice of you. Is there any particular method to make sure it is fully drained? The only thing I can think of is to pull the power when in the pc and keep hitting the power button on the pc to drain the mobo of any residual power.

That's a valid way of discharging the charged components. Some PSUs have a bleeder resistor to do that for you, but there's not really a way to know that ahead of time.

The psu I have is the 1010w gamexstreme. I found that it is soldered on. I found a mod on another site that had the fan cut out and just replaced with a 3 pin onto the motherboard so the rpms can be monitored and controlled. I have 4 extra gentle typhoons laying around from water cooling so I think I will just use one of those. Thanks everyone! But if you do have any extra tips involving not making my heart stop from electrocution, im all ears!

I don't know how other's go about discharging their PSU's but I shut the system off completely, disconnect the power lead then hit the power button and watch the system "flare up" and fade thumb.gif

Pulling the plug on a running system would achieve the same outcome, I just like to shut down the OS properly... who needs HDD/OS issues as well eh? tongue.gif

On a related note, my Thermaltake W0106RU 700W psu has developed an intermittent but regular squeak that is almost certainly coming from the ball bearings of the fan.

Does anyone know how the fan attaches in this particular range of power supplies? Please tell me it's not soldered to the board...I've taken apart a couple of cheap PSUs before, and those were.

If it detaches in a reasonable way, I can just get a 140mm fan and replace it.

Nice Hi-jack! thumb.gif


In all seriousness though... even if it's soldered to the PCB you can always cut the wires and rejoin them to your new (replacement) fan, as long as you make a good electrical connection (respect the polarity) and isolate it you'll have absolutely no problems biggrin.gif
