I have this great PSU since 2008 but it's fan is getting noisy so i'm searching a replacement...<br><br><br>
This is the stock fan, an <b>ADDA AD1212HB-A71GL</b><br><br><a class="H-lightbox-open" href="http://www.overclock.net/content/type/61/id/2119583/"><img alt="" class="lightbox-enabled" data-id="2119583" data-type="61" src="http://www.overclock.net/content/type/61/id/2119583/flags/LL" style="; width: 500px; height: 493px"></a><br><br><br><b>Specs</b><br><br><a class="H-lightbox-open" href="http://www.overclock.net/content/type/61/id/2119584/"><img alt="" class="lightbox-enabled" data-id="2119584" data-type="61" src="http://www.overclock.net/content/type/61/id/2119584/flags/LL" style="; width: 1675px; height: 63px"></a><br><a class="H-lightbox-open" href="http://www.overclock.net/content/type/61/id/2119585/"><img alt="" class="lightbox-enabled" data-id="2119585" data-type="61" src="http://www.overclock.net/content/type/61/id/2119585/flags/LL" style="; width: 1672px; height: 33px"></a><br><br><b><br>

Try to keep it around the same or higher cfm, and nice low noise (DB), looking at your old one it´s putting out 85.2 cfm, also you want to look at keeping the wattage as close as possible.<br>
My choice would be this one.<br>
M12-2 1250rpm 3 Pin 4.5 V / 12.0 V 16 dBA 87.0 m³<br>
You could probably just get away with lubricating the bearings if you wanted to , there´s a great guide <a class="bbcode_url" href="http://www.overclock.net/t/773256/prepping-a-sleeve-bearing-fan-for-work">here</a> if you want to have a go.<br>
edit ; Does it still have warranty ?

Why would you prefer that model ?<br><div class="quote-container" data-huddler-embed="/t/1505284/noiseblocker-fan-for-a-corsair-hx520/0_20#post_22650994" data-huddler-embed-placeholder="false"><span>Quote:</span>

I prefer to change the entire fan because i can get if for free...<br><br><div class="quote-container" data-huddler-embed="/t/1505284/noiseblocker-fan-for-a-corsair-hx520/0_20#post_22650994" data-huddler-embed-placeholder="false"><span>Quote:</span>

Because I hate noise , anything over 1300 rpm for me is noisy , it´s also the closest for CFM which is important to keep a similar or better airflow over the components. You could go up to 18 - 20 DB with a higher cfm if you want to be sure , just watch the Start/nominal voltage, I think if you keep it at 4.5 you should be OK.<br>
It might even be worth writing a quick email to corsair to check that last point.

<br>
85cfm vs 51cfm (87 m³h) ...<br><br>
So i would need around 140 m³h to get the closest to the original fan.

Yes mate , I missed the m³ damn imperial / metric<br>
maybe this one with slightly less CFM .<br><br>
M12-P 2000rpm 4 Pin (PWM) 4.5 V / 12.0 V 29 dBA 133.0 m³<br><br>
Your fan will probably never get up to full speed anyway, unless you have poor case flow, high ambient temps, and your seriously overclocking .
