120mm @ 800rpm, how much cfm?

How much air (in cfm) would an average 120mm fan (25mm) move spinning at 800~900rpm ?

Sorry if the question is a bit vague.

My knowlegde of impedance curves is lacking, so please feel free to enlighten me. At the moment my case has 2 positions for 80mm fans at the rear. My original idea was to simply cut over the 2 80mm "stamped" grills to make a hole for a 120mm fan. But it would be far easier (and look much nicer) to u...

2x80's > 1x120 ?

OK, this is probably a stupid question, but would two 80mm fans be quieter than one 120mm fan blowing the same cfm?

The 350watt has a 80mm fan, not sure about the others.

You're the first South African i've encountered on these forums...i'm not alone :)

I thought as much considering they're so cheap and none of the offerings on Rectron's pricelist are on AOpen's website. I originally opted for the 400watt but they don't have any stock...*sigh*

Thanks for the replies.

Ok, i managed to find out the amp ratings, they are as follows:

3.3v.........20
5v............20
12v(1)......14
12v(2).......8

Will that be alright for the system i specified above?

AOpen 350watt - Enough Power?

Putting together the following system: Athlon64 3500+ NF4 Mobo PowerColor X800GT 1 x 160Gb Sata HDD 1 x DVD Writer 2 x 512MB RAM Would the AOpen 350watt have enough power for the above mentioned system?

One of the guys from my local forum did the same thing. It can't be passively cooled with the NB47J, but placing a undervolted 80mm fan above it will improve it's performance drastically. Alternatively try the Thermaltake NB Spirit Cooler.

A knock to the rear fins on the schooner could damage both the gfx card and the motherboard. Also in my part of the world the schooner is quite a bit more expensive than the z...

Cool, thanks man! I really appreciate it.

I'm worried the NB heatsink is too close to the AGP slot. It looks like it will just fit, but i want to be sure.

Thanks again.

Yes, turning down the psu fan is risky but as long as the temp is monitored it won't be a problem.

The 92mm fan i referred to earlier is the one on the Zalman heatsink (7000B ALCU), which i plan on ducting to the side of the case to bring in the coolest air possible for the processor.

Yeah, seems even when the air coming out of the psu is mildly above room temp, the fan is spinning too fast.

I'll try what u've suggested, i just gotta find a temp probe somewhere.

Is 65'C not too high though?

I'm not quite sure what u mean. Let me explain exactly what i intend on doing - to avoid further confusion. 120mm at rear, 120mm in front. Zalman 92mm sucking in air directly from case side. PSU fan blowing air out. This should result in a slightly positive case pressure (as the PSU only has a 80mm ...

If I read that right, then the PSU is the only exhaust in the case now. Adding another exhaust would be the first thing I'd do too, as that reduces the heat load on the PSU. But I would only put a fan on the intake if the HD was too hot, as that won't help with cooling the rest of the case. Yeah, b...

Ah come on, not even one reply. I thought someone would at least recommend replacing the fan with a quieter one. I thought of cutting out the front entirely and replacing it with some mesh. This would obviously decrease the pressure and thus airflow speed but i think it would do away with the vacuum...

Well the subject of this thread pretty much decribes what i'm trying to do. I have a 300W AOpen PSU that uses a 80mm fan for cooling. The noise is rather like a vacuum cleaner, as it sucks the air through the PSU. Does the the box shape of the PSU amplify the sound at all? Currently i've removed the...
