Replacing PSU fan - Silverstone Zeus 750

[tjelaw]

I was thinking of replacing the 80mm fan in my PSU for a quieter one.

Does anyone have experience and tips with replacing fans in Silverstone PSU's, the ST75ZF in particular or just PSU's in general?

I'm aware I cannot just put any quiet/low airflow fan in there. I was thinking of the Noctua NF-R8 (http://www.noctua.at/main.php?show=productview&products_id=9&lng=en), they are relatively expensive but have one of the best airflow/sound ratio's,

My biggest concern is; what kind of fan connection do these PSU's have internally? just a standard 3pin or is it maybe a solder on the circuit bord?

Usually it is a two pin connector or it is directly soldered to the circuit board.

Most PSUs use the 2 pin connector. It may be glued into place so you'll have to remove that. But whatever fan you go with you'll want to plice the connector of the old fan to the new fan. As long as you get a decent fan you'll be fine. Just be sure to be careful. Not that you'll be near the underside of the PCB where you would run a greater risk of shock. I would hope you don't have to compleatly remove everything from the case.

The undervoted Panaflo in my OP-850 developed a really annoying tick/whine, so I replaced it with an NF-P12. Couldn't be happier - PSU is if anything cooler running and inaudible at all but the highest loads.

yeah the noctuas are great fans, only cons they are ugly

I don't think looks are a problem when they are sitting inside a PSU. ;)

Possibly. They actually look pretty good seen against black, but I do agree, the colours aren't for everyone.

Ok, I did it :)

unfortunately I forgot to take pics in the proces. But if others ever want to do the same with this PSU; the fan is connected with a strange 2 pin connector.

What I did was to cut off the connector from the old fan, and just soldered it to my new fan. Plugged it in, closed the PSU and it works like a charm. My new fan had 3 wires, I just cut off the yellow one that was left over. I used the Nexus 80mm fan in the end, white fanblades in black PSU works for me :) And its supposed to be better performing in airflow restricting places then the Noctua (air pressure etc.) Anyways, im happy with the result, it really makes a big diffirence in noise coming from my PC.
