PSU fan noise -> replace fan/ PSU ?

[z3r0]

My PSU fan had started making lot of noise. It is a sleeve based bearing Fan. I tried using sewing machine oil to silence it, it was running without noise for a couple of months and the noise started once again.

My current PSU is : Cooler Master Extreme Power 600W Power Supply

1) Can you please suggest whether I can replace the fan alone, if yes, can I buy any 120mm Fan or what spec should I check ?

The existing fan in the PSU is:
Model Part Number: AD1212US-A71GL, 12 Volts, Current 0.5A
Service Unavailable

2) If I have to replace whole PSU, can you suggest some good PSU for my current PC config below. Budget: Rs.3000 to 5000 (should be able to support any future upgrades )

My PC Config:
Processor: Intel E8400
Mother Board:Abit IP35E
RAM: Corsair 2*1GB(800MHz) - TWIN2X2048-6400
Graphics Card: Sapphire HD5670 1GDDR5 PCI - E HDMI/DVI-I/DP
HDD: Western Digital Caviar SE16 320GB 7200RPM 16MB (WD3200AAKS
Cabinet: Cooler Master Elite 330 Computer Case
DVD Writer: Samsung SH -S203 SATA DVD RW or Lite - On 20X With Light Scribe
UPS: APC 650VA

that CM psu is not considered reliable-it will be a better idea to replace your entire psu rather than getting its fan repaired.Look for Antec VP450p-i think it will suffice for your needs.

Antec VP450P cables are too short so its better to go with Corsair CX500 @ 3600.

Yes, the fan can be replaced yourself but it will void the warranty. All you need to do is cut the wires powering the existing fan, get a new 120 mm fan and solder the cables together.

Thanks for the answers, the current Cooler Master PSU was bought in 2008. It is running without problems so far. Considering my area is prone to lot of power fluctuations !

I am considering to buy a new PSU, may be will repair the fan keep the CM as standby PSU.

I am in a dilemma between: Seasonic S12II 430 Watts PSU & Antec Antec VP450p.

My requirements are the PSU:
should be able to handle seviour power fluctuations, without burning out/ blowing up capacitors inside
should fit into my current cabinet Cabinet: Cooler Master Elite 330 Computer Case without problems
should be silent. I guess the Seasonic has a ball bearing based fan.. will start making noise sooner ?
should survive at least the next 5 years

Seasonic S12II 430 Watts PSU is best suited to your purpose.


Antec VP450P have very short cables.

Antec VP450P have very short cables.

it is short.but that does not mean that it is not fit for any cabinet. his cabinet is a small one. vp450p wont make any problem unless you go for biggie cabinets.

@ op, between Seasonic S12II 430 Watts PSU & Antec Antec VP450p, there is only one choice and that is the Seasonic S12II 430.

I have decided to buy Seasonic S12II, but questions below

1. will Seasonic be creating problems with my UPS: APC 650VA.
I read somewhere it would create problem due to output waveform is "Stepped approximation to a sinewave". The UPS Output Power Capacity is 390 Watts as per APC website

2. should I buy 430 Watts / 520 watts, considering I will not use more than one graphics card / overclock.

3. My current PSU "Cooler Master Extreme Power 600W ", though labeled as 600W as per reviews it is only 450W. Haven't faced any problem with the UPS, except one or two abrupt power outs

1)Wait for someone to answer.

2)Seasonic 430 watts will do.

3)Seasonic will deliver full 430 watts so not an issue.

Would like to know whether this would be compatible, with Seasonic S12II 430 / 520 watts

I went ahead ahead and bought Seasonic S12II 430W. I tested with the APC UPS above. It works fine. But the backup time seems to be very less around 5 mins. But it is good enough to shutdown the system properly.

I have used this setup for 4 days now.

I had couple of instances on the first day when the CPU powered off abruptly. First one I dont remember whether I was on battery mode. Second time I was on UPS battery mode for around 5 mins.

There was no low battery beep warning from the UPS, the just blacked out.

After this I had tried switching off the main power to be on UPS battery mode, multiple times, didnt run into this problem

I think the UPS battery is acting up.
