Noisy PSU

[s_sachin]

The PSU noise is noticable or should i say quite audible in my htpc.Please let me know if you have any recommendation for a 'silent' psu, I have the iball baby case.

one more thing , i think the noise increased when i replaced my old dvd drive with a blue ray drive. But i cant be sure as it is persistent even if i disconnect the drive.

thanks

I am using VIP gold 400w which has big fan with hardly any noice.

spirovious, are you using the iball baby case, will this psu support micro atx where space is a premium

thanks

thanks guys.

@theironhorse - do you remember the model number ? I serched the cooler master site and I could not find any tagged as micro atx

An easy solution than changing the psu is to find out the cfm of the fan used in the psu and replace the fan with the low rpm / silent fans or try low rpm 120mm fan (some DIY effort may be required for this)

 

[spirovious]

I forgot to tell that my VIP has a small controler switch(like vol control)which is said to control fan speed of PSU.

As suggested by others, replace psu fan. Zalman make with rubber clamps instead of screws recommended.

Thanks guys .. i am going to try some of these options before going for a replacement.

I googled and found a solution of applying sewing machine oil to the fan joints. Have tried , cannot say it has solved the problem.

I think the next option is replacing the fan. One question i had was , the fan is in an external attachment to the psu and can be easily replaced, but the wire is soldered to the circuit board of the psu.

I was thinking to just cut this off , replace with a new fan and just attach to the power pin that the psu supplies (which also powers the cabinet fan). But my worry is , will it still get the information from the psu to regulate the speed etc.
Any advise on this ?

thanks
Sachin

Just to close on this , I finally ended up byuing a new cabinet (CM elite 310) and new powersupply (FSP Saga 500W). And its silent now

I tried with some other powersupplies like techcom etc. But got same noisy results with the iball baby. So just a note to all planning to use this cabinet in future, although the cabinet is great with its form factor, it is very difficult to get a good quality mirco atx power supply. so please think before you buy this.

The CM elite 360 is another option which can be placed horizontaly.but was not avialable when i went to buy.

thanks

try to replace the PSU fan or replace the PSU with the new one like corsair vx450

 

[s_sachin]

tried everything (cleaning , applying machine oil to fan contacts etc) except replacing the fan. A standard PSU does not fit in this case, its a small form factor case.
