Help me to choose a new fan for my OCZ 600 watt PSU (OCZGXS600)

[Un4GiVeN78]

Hello,
My PSU(OCZGXS600) is getting very noisy lately so i decided to replace its fan, The problem is i don't know the fan specifications to buy a similar one so, May you guys tell me the minimum specifications i should have on my new fan like:

Voltage ??
Speed (R.P.M.) ??
Air Flow (CFM) ??
Current (Ampere) ??
Air pressure (mmH2O) ??

Thank you

Can I strongly suggest not messing with the internals of a PSU? Aside from the potential shock hazard even after unplugging them, those fans are usually soldered in and are monitored by the PSU. If you do any damage in there, you run the risk of shorting out other components in your system.

If the fan is noisy, check to see if it needs to be cleaned. You could use compressed air to clean it out. If that doesn't solve it, go to OCZ and see if they will replace the PSU.

I second what DF has said above. Contrary to what a lot of people believe (and that is a PSU is basically a step-down transformer which is safe so long as it isn't connected to the mains), a PSU is a complex piece of hardware that contains a number of capacitors. These capacitors retain their charge for a considerable period of time after the mains has been disconnected. They are also capable of giving you a serious jolt should you accidentally short them, even removing the PSU cover can cause such a short if you are not careful. For those with pacemakers or some other heart condition, the shock or jolt could prove fatal.

The best way of cleaning the fan in a PSU is to use compressed air from an aerosol manufactured for the purpose of removing dust and grime from electrical equipment. You should find these at your local computerr hardware store.

I opened the PSU and i removed the fan sticker and i used a spray called " AKAI " in blue bottle then i placed everything as it was and now the noise is even worse! Moreover i've lost my warranty coz i opened the PSU. Is there any thing i can do except buying new PSU to solve this?

 

[DeaconFrost]

Not really. That's what we tried to warn you about. There's no good to be had from opening a PSU case.

 

[Dwarf]

Again, not really except buy a new PSU. Take the opportunity to get one with a greater rating, such as 750-850W, as this will allow you to upgrade your system in future (better graphics card, etc).

Consider it a lesson learnt, albeit an expensive and potentially dangerous one.

Remember when cleaning dust and other detritus from computer hardware to only use a can of compressed air. Never use anything liquid-based, such as WD40 or the stuff you used (even if it does evaporate). There is no telling what damage the contained solvents could do.

Thank you guys for your help.
I bought a pc few months ago it's completely silent it has a HEC(Gamma) PSU, I will replace my OCZ with the same HEC PSU i have on my other PC.
Also my rear case fan is noisy coz it's always running at maximum RPM i will replace it with a new rear case PWM-fan or something quieter.

What size is the rear fan? If it is 80mm or 92mm, and your case accepts a 120mm fan, then fit a 120mm one. To shift the same amount of air, because they are larger, they don't need to spin as fast and consequently are quieter.

 

[DeaconFrost]

Excellent advice. My cases all use 120mm fans, and they are nearly silent.

hmm Here is my topic (http://www.sevenforums.com/hardware-devices/156544-chassis-fan-control.html) i tried to control its RPM to lower the noise but i couldn't, ohh and It's a 120mm one.

 

[DeaconFrost]

I have those exact fans in my CoolerMaster HAF 912 cases. If they aren't silent, you either have a slightly defective fan, or else the noise is coming from the mounts...rattling against the case. Are your mounting screws tight? What case do you have?

 

[Un4GiVeN78]

I have Gamma Case, I mounted my rear case fan myself it's tight. it is noisy because it's running at 2000 RPM all the time

 

[DeaconFrost]

I'm pretty sure mine are running at somewhere around 1900 rpms, if I remember correctly. Those fans are designed to be silent, as described by Dwarf in post #8.

Don't worry about it guys.. I will buy a new PSU and new rear case fan same type as my other case.. My other case is Cooler Master Elite it comes with 120mm rear fan and it's 100% silent i try will buy this fan individually from a store with HEC Gamma 500 watt PSU for my HD 5850 GPU it's gonna work instead my noisy 600 watt OCZ.
Thank ya all
