Interesting!

looks good thou

Just got two deltas today
Purrs like a kitten :3

whats the ampere of the fans?
and how do you control it?

I used lamptron fc9.... supposedly provides 50w per channel but the fans have some trouble starting up. have to fiddle abit with both or one by one to coax the beasts awake... then they can go max with no problem ^^

Well yeah, lamptron fan controller control fan by voltage, not pwm, thats why your fan had problem to starting up
High ampere fan usually will not start to spin untill they were supplied with enough voltage, eg 7V.
if controlled by pwm signal they will spin even at the lowest speed(but they still noisy though).

Hmm?

Well with just a little tweaking I could still get the two to spin fast but silent... the airflow feels like 140mm nzxt stock at 1500 rpm

You didnt get my points
Eventually you will feel tired with fan noise lol, i used to control all the fans with fan controller, but over time it become hassle cause need to control manually
Now all my fans are controlled by mobo, i have 2 fan controllers, one is for testing fan only, the other Lamptron is collecting dust

anyone 1 can tell me where can get the artic cooling 80mm case fan?? is it nt available at market d?? i cant find it at garage sales

nope, not available, hasn't been available and IMHO won't be available in the local market for a long time... been searching for it for some time now

im looking for 120mm fan with highest airflow and lowest noise..is there any LOL but price below 35 each ^^
im using 690 II advanced cassis

Seems to me like the Artic F12 is your choice then cause at that price you ruled out noctua, noiseblockers & darkwings already

how to look and compare for a good case fan?

Only ac then get the Pwm version then u can use without a fan controller

if its for intake & exhaust, I'll just pick the one with the best airflow (CFM)/noise (Sone, DB) ratio... and of course within budget thats specified

but take all fan specs with a grain of salt as some of them does not exactly perform as stated

Added 4 Xigmatek XLF-F1255 to my case, but realise it's too noisy without fan ctrl.

Now these are quite rare... u sure they are F1255? or are they F1254?? cause the 4-pin type is hard to find

Sorry it should be F1254, thanks to Lamptron FC5, now i can either turn off the fan at night or max out for gaming
