The included fans are pretty weak tbh
I'm just a bit worried about the ticking noise you mentioned - I'd like to be able to run them near-silent for browsing (under 20dB would be ideal) but then crank them up for games/benching.
I've had a look at delta's site before, but the naming system scared me off
so any help is greatly appreciated.
Don't bother with 140mm. I've been very dissapointed with most of them. There aren't any cheap delta 140x25 (I'm not even sure if they exist)
Arc Midi R2 has a lame excuse for a filter right? - A foam filter that is
I got a few new deltas and i don't experience ticking issues anymore ... Strange. I tested my FFB again and it doesn't exhibit that. Again very strange
Here's some help :
AFB - standard 7-blade no stator air foil, highest CFM but the most dispersed airflow of any delta.
FFB - 9-blade with stator air foil, a lil higher noise per CFM
WFB - 7-leaf ish blades, lower static pressure but in the end AFB fans outperform them. Only benefit is their low, low price
EFB (Rare) - 3 blade very steep curve. AFB fans outperform them and their design is a bit long in the tooth already, only nice for their sweet tone
PFB (Rare) - 11 blade Doesn't have the whine the FFB fans have but of course aren't as focused as the FFB series are, quieter and nicer tone
AUB (Rare) - Are actually AFB fans spec-wise but are a bit strange. Acoustically like AFB fans but i'm not too sure
The other series are not within our concern
Then here's the naming strategy - like for example AFB1224M
AFB is the series, 12 is the size 24 is the volts, like 24v. M means the speed rating. 25mm thick fans don't have any lettering behind them but 38mm thick fans are written with a E behind, 32mm are F and 28mm are N
There are also the **C models (example AFC1212DE) which are either OEM versions of the **B models (AFC1212DE 1.6A = AFB1212SHE, AFC1212DE 3.0A = AFB1212GHE) or Sensflow (WFC1212D, AFC1212D) models or new models of the **B or so i've been told ... Like the FFC1212DE which i've put forward for now but i really want that fan being that i own the FFB1212VHE (PWM of course) and i love it

Odd indeed.Edited by DaveLT - 10/14/13 at 1:06pm
