Changing PSU Fan

I have XFX PSU 650W pro series core edition under full load and normal room Temp about 26~31 The Fan is really loud. Enough that I can hear it while wearing my headphones and maxed out the sound. So I though about replacing the fan. I googled it and found out that it's might be dangerous most of the time but since I will send it to a Pro or something like that it's not a problem 

 

But might changing the Fan cause the PSU to be damaged !? ( The new Fan will be a pretty good Fan from a decent brand which I still don't know )

It's pretty easy, just buy the correct size fan, take your psu out of your case, makesure it is off, unpowered, open the psu, take out the fan, put in the fan, close the case. You may need to buy an adapter for the 3pin to work with the PSU, depending on your PSU. I've done it a few times and it's pretty easy. I recommend wearing a ESD wrist wrap to ground yourself to prevent any chance of damaging the PSU.

It depending on the circumstances and the conditions the PSU is subjected to, in general it won't affect the PSU as long as you are not constantly running it max power or using it in very extreme temperature conditions, they test PSU's in extreme conditions and to ensure guaranteed MTB(mean time before failure) they need the necessary cooling but as long as you are not subjecting it to extreme heat or very high loads it should not be any problem. I personally have a TX750 with a replaced fan, at around a max of 500W with no problems. For the replacement you'd want to drain and let the PSU and let it sit a minimum of 30 mins to ensure full discharge on capacitors before attempting a replacement.

You should not damage the PSU from changing the fan to something quieter, but it will void your warranty, so be careful of that. And PSUs aren't something you just want to go poke around in, they're high voltage stuff (even when unplugged, since capacitors can store energy).

No it wont reduce the efficency, thats not related tothe fan. As long as you understand you will void your warranty then go for it

I know that I will avoid warranty But I got no option I thought about replacing it but my budget won't get any PSU better than this ( thermaltake SPS 730W Se Smart or EVGA 600B for example ) So I think the best choice is to swap the fan to quite one
