Looking to replace the current stock fans in my CM 690 ii adv case.

Primarily want them to be as close to silent as possible but also to push a lot of air through. Plus to match my colour scheme of black/white/blue.

Budget is £15 per fan

The case accommodates 120mm at the rear and 2 x 120/140mm at the top I think I'll probably leave the stock front one there. These will also be connecting to my Bitfenix Recon.

I've had a look around and these NoiseBlockers have good reviews but wondered if anyone had any other recommendations.

YOUR BASKET
3 x Noiseblocker NB-eLoop Fan B12-4 - 120mm (2400rpm) £11.99 (£35.97)
Total : £39.88 (includes shipping : £3.26).

 
I put these in my old CM690. They were pretty quiet and matched the case nicely. Those noiseblockers might be fairly noisy given that they're 2400rpm (although I guess you're connecting them to a controller). Are you just using the fans for case airflow, i.e. no radiator cooling?
 
Hmm good point, will the fan controller be able to reduce the rpm so that they are more quiet?

If so I could go for the slower ones?

Yep, these will purely be for case airflow as no watercooling.
 
I personally love Noctuas myself and the Redux versions not only come cheaper as they omit the mass of accessories and extra cables, but they have non-beige colours while retaining the same high-performance:low-noise balance.

Those Aerocools do look quite interesting, though. If it weren't a Friday afternoon, might start comparing stats.

Just be aware that most fans make some kind of noise above 1000rpm and any airflow going through mesh/grilles/vents will also make noise. Depending on your case, you may also get either resonance, vibration and/or further noise from internal airflow around your components.
 
Thanks for the suggestions guys, I like the look of the Alpenfohn's but think I still prefer the Noise Blockers compared to them.

Don't really like the Aerocools design plus they seem to only go 1000rpm so not sure how much air they will push?

You wanted as close to silent as possible, anything over 1000 RPM is pointless.

Thermalright TY-147 are about as good as 140mm fans get.
 
I don't think it matters, although it's nice to have extra performance available in case you need it.

If you can go for the biggest fans you can fit, bigger = more air flow for less RPM = quieter.
 
Cool, i think i'll go for the 1900's then and just slow them down with my controller until i need extra performance.

Cheers Telecaster!
 
I've been using Akasa Apache and although I keep an eye open for an upgrade I've not yet noticed anything that pushes the same amount of air at those low noise levels. Anyone think of anything better whilst keeping the noise under 20dba? I'm using two with a corsair H80i CPU cooler in push/pull format and could do with a little more airflow if possible although I don't want to get get noticeably louder (within reason, a little louder isn't a problem)

I don't think Apaches are best optimised for pushing through a rad are they? they're nice case fans though.

What speed do you run them at?

eloops seem to be the fan of the moment, I can't vouch for them though as I haven't tested them, I have one on the way with a couple more 140mm fans.
 
Ah, hadn't really thought if a fan needed to be optimized for push/pull with a rad, you learn something new every day.

So what would be the recommendation for best combo of fans for Corsair H80i (cooling a O/C 5820) giving a good mix of airflow and noise. The Apaches are running at 1200 and seem pretty quiet for all intents and purposes. The default Corsair fans the H80i came with sounded like a whinny high pitched jet turbine by comparison although they did seem to give me slightly better temperatures.
