Guys, I really cant decide between Nexus and S-Flex 1200RPM, considering I can have them for about the same price.

Maybe I should buy both? The nexus for case fans (vertically) and the s-flex for cpu/gpu(horizontally) ??

arghhh

I personally went with the S-Flex 1200rpm for my last build. Hope that helps.

Noob question - How do the new Slip Stream fans compare to the Nexus fans? The numbers seem a bit.. incredible.

The place I'm buying from only seems to have the fluro Orange Nexus fans

Any idea how the SilenX IXTREMA 120 fits in this list? According to an anandtech article it claims the best airflow to noise ratio, but is that really true? How does it compare to the Nexus and the Yate Loon?

Greetings,



The numbers are not real, but the 500RPM and the 800RPM Slipstream models are very quiet; probably quieter than the Nexus. The 500RPM is quiet at 12v, but it can barely be undervolted. The 800RPM is more flexible. They seem to blow a bit more air at a given RPM than does the Nexus, as well.

Slip streams the way to go? might pick up a controller as well.

The S-Flex is probably better in a few select areas e.g. highly restrictive environments like heatercores, but you basically can't go wrong with a 800rpm Slipstream assuming you have a decent heatsink.

If you are planning on picking up a controller anyway and are concerned about the efficacy of your heatsink(s), a 1200rpm Slipstream on a controller (make sure to get one that will go down to a good 5v minimum) wouldn't compromise quietness too much overall (the 1200rpm Slipstream at the same rpm as the 800rpm model tend to be the louder of the two).

Hope this helps,

I can attest that the SlipStream 1200 rpm model I bought has a very pronounced vibration when mounted horizontally (just what I expected from a sleeve bearing fan) even at 5v, while my Pabst syntec sleeve bearing fan even at 12v mounted horizontally doesn't approach the level of vibration the Slipstream exhibited.

hi all,

which one is quieter AND has higher cfm in a restrictive airflow environment, running at 7v - the Papst 4412 or the S-Flex series, or Yate Loon Medium's or...?

I've found the SlipStream 1200rpm exhibits a annoying low-level throbbing "hum" when in a restrictive airflow environment (still noticeable at 7v if I put my ear next to the fan), and I want to find something quieter.

Thanks!

I can feel no vibrations from the slip stream 1200 i have mounted as top exhaust on my p182 even at 1200 rpm.
The case vibrates slighlty, but it feels the same even with that fan off, could be due to the heavy dampening materials i used i guess.
The first few days i had a clicking sound from the horizontaly mounted slipstream, but that has disappeared.

So which fan would be better? the S-Flex SFF21E 1200rpm or the Slipstream SY1225SL12M?

Exactly which one would be the quietest and its lowest settings but have a good CFM at 12v? the slipstream or the s-flex?

For a restrictive environment (heatsink, radiator, etc) get the S-Flex but for a non-restrictive environment (exhaust, intake, etc) then the Slipstream would be ideal.

I did a comparison between the 1200rpm M Slipstream and the 1900RPM SH Slipstream and I am surprised more people do not recommend the 1900rpm model (at least for CPU cooling as opposed to case fan only).

Whilst the 1200rpm model increases very linearly between 5V to 12V, the 1900rpm seems to have a much wider range and can go really very quiet too....subject to 'clicking' that might or might not be heard when it is undervolted. yet it also has a lot of extra top-end clout.

I know this is for silent computers, but wouldn't you like to have your cake (silence 80%) and eat it (cooling headroom for OC'ing 20%)?

Only issue i saw with the 1900rpm model is that it's dba was not linear like the 12M so you would need a fan controller with good control between 5V and 9V.
The only place where the 12M shines is 24CM and 18dba ambient, where SH only does 20CFM at that same level, and also it is easier to control and never gets 'too noisy'.

I must admit this fan stuff is far moreinvolved than I ever thought!!!

Would love to see some review action on the D12SL-12 PWM

I have very positive experience with Xilence fans, they cost about 2.5 euros (~200 dinars here in Serbia) and are VERY silent.

The Recommended Fans page is 4 years old.

Is the list still valid?

Good question. I think it's true for nearly all of the recommendations here. They quickly become outdated.
