Replacing the PSU fan.

Hi:

My PSU's fan is starting to die. Currently I have 3 Cooler Master SAF-S84-E1 for the case and they are very quiet and keep the MoBo cool. I was wondering if I could replace the dying PSU fan for a SAF-S84-E1, considering they run at 1400RPM and have an air flow of 15.75 CFM. The PSU is a generic one rated at 400w.

There is one important thing: Noise is a big factor for me as I use the PC for audio mixing and mastering, so low noise is a must. Previously I tried 2500RPM fans for the case and the noise was unacceptable. I also must add that I won't be replacing the fan myself.

Another question would be, what kind of PSU would I need if I want to run my e6550 at 3Ghz with an ASUS P5K-VM? However its way more important to me the answer for the first question.

Thanks in advance.
 
Swapping the fan is pretty easy, just did mine last week actually. Chances are the power supply fan's power connector may be different but if your new fan as the standard 4 pin molex just run the wire outside of the unit following the unit's power wires, then plug it in to an open connector.

Should be good to go! IF your computer suddenly starts to randomly shut completely off the fan is not large enough to keep the power supply cool and you'll have to replace it with a higher rpm fan.
 
The first thing I recommend doing is checking the current PSU fans ratings and power draw. If the fan you are contemplating installing is higher rated and has equal or less draw then I don't see a problem.

What else are you running in the system? Hard drives, video card, etc.
 
2 ddr2 sticks (2gigs)
2 sata 500gigs each
1 160 IDE
1 DVD/CD R/RW
1 m-audio sound card

No videocard.

How do I get to know PSU fans ratings?
 
Examine the sticker on the PSUs current fan. Write down the make / model number and do a search through your favorite search engine.
 
Yes, you can use the CM fan. However keep in mind that if you splice into the original fan lead then a fan controller could adjust the fan RPM as needed.

How many hdd's? What video card? Assuming 1 hdd and a GTX260 then a Corsair VX450 would suffice.
