Default Fan for PSU

Hi!
I'm eager to make my PC maximum silent. Unfortunately, my PSU Zalman ZM600-HP proved to be unexpected noisy as for Zalman... The problem is in default fan (ADDA AD1212MB-A71GL). According to specifications it's nois level is whole 38 db/A! Meanwhile it designed for generating 80,5 CFM airflow... Other significant tech parameters of this cooler are: type - ball bearing; volts - 12; current - 0,33 A; power - 3,96 W; speed - 2050rpm; pressure - 0.117 inches; weight - 156 g.
Power consumption of my system is near 380 W at full load.

Have you any idea of best compatible silent fan for replacing default one? Will be better for me if it is Scythe, because I'm big admirer of Scythe products! Though I will be glad for any advise.

The problem is seems to be solved! I need one of new Scythe Slip Stream Fans - SY1225SL12M (1200 rpm, 68,54 CFM, 24 db/A) or SY1225SL12H (1600 rpm, 88,11 CFM, 33 db/A). Does anybody know, when this products will be shipped worldwide?

Hi,

the 2000RPM can not be called silent, even 1600rpm would be more on the performance side. The 1200rpm should be a lot better if you talk about noise. Does the supplied fan slow down when it is running in the PSU? Usually the PSU has a fan controller inside it to power-up the fan if necessary, but some really good PSU power up the fan at 3v and that might not be enough for most fans. So not sure how it is with the Zalman PSU.
I assume it will be fine with Slip Stream, yet please be careful with opening and modifying any PSU - it's warranty voids for sure.

The Slip Stream should be available world wide. Please visit our where to buy list to find the right shop.

Cheers,
Andy

Just a little reminder: sleeve bearing don't live long in PSU's: high temps combined with horizontal fan orientation kill sleeves fast. Be sure to check the fan's condition at least once every 6 months.

P.S. ADDA AD1212 = Scythe S-Flex, except for the bearing.

Thank you for this usefull advice! Finally I've installed Scythe S-Flex (SFF21E) with fan controller and very happy with its noise/performance/reliability level.
