Sure? Don't the AC's come in unique color combos anyway? (i.e., no competition)Quote:

My stance on LED fans: you're buying for looks. As long as the fan is within your noise and aesthetic tolerance, it's a good fan.
Fan Roundup 3 has begun....results follow

This thread will still be the stickied thread until I'm completely done with Roundup 3. I'll post links to all of the mini-reviews that will contribute to Roundup 3 in this thread :)
hehehe i'm not a fan of leds too. just wondered since quite a few members use led fans & saw that AC Ryan 120mm fans are spinning at 2000rpm, 77.70 CFM & 28.95 dBQuote:

Do you know anything about the Panaflo FBH-12G12L fan. It is an older model that has an aluminum casing.. I believe the specs are 38mm, 30db, 1700rpms, 68cfm.
Thanks

hi does fan controllers lower the fan performance or not at all? at the moment im using 120mm Yate Loon D12SH-12 from PTS and a scythe kaze master 5.25 bay fan, trying to figure it out if it does cause ill be using them on my rads.
What do you mean lower performance? It'll undervolt them (I'd think, I'm actually not sure how the Kaze Master does it's thing)...which means they'll spin slower, which in turn means less airflow and also less noise.Quote:

Normally u loose half a volt or so through a fancontroller. So on max it is probably around 11.5v (ish) instead of 12. I know sunbeam rheobus does this but i havent testet many different fancontrollers to very this.
That depends, but the best answer is "yes"
Most fan controller's max settings aren't 12V unfortunately. I know the Sunbeam Rheobus (20W version) has a max of ~11.4V on really low-load fans...like 11.15V on something like a San Ace H1011 and something like 10.9V on some Deltas. A Yate Loon D12SH-12 will probably run at like 11.35V or so. I use a Zalman MFC1 in my main system and its rheobus channels have a max of like 10.5V with Yate Loons (well, all fans really).
Ah, i dint know about the difference in max voltage variation with different loads... never really thought about that.

Lol, is that some chinese saying, fortune cookie or something? :P:
Metaphor I like to use for arguing on the internet :p:
That's why fan controllers should be rated by ampers instead of Watts. If they can't produce enough current, they won't be able to fully load some fansQuote:

Vapor, ever encountered these?

They have a similar blade design to the 1011's, look a bit interesting IMO.
No fanamps produce any current. They just take the 12v from the psu and "burn away" the unneeded voltage.Quote:

my FLEX-E I can adjust 30 rpm at a time with small movements but one small movement on the F and thats it
anyone notice this ???? I just touch the voltage down a 1/8th of a turn and the fan powers off :(
On my MB sensors they undervolt gracefullyQuote:

Buy a crystalfontz controller with PWM. It dials up and down to the nearest 1% of power and it uses PWM which eliminates some of the clicking and other odd noises you get from normal fan controllers.Quote:

PWM states for Pulse Width Modulation outputs and that's what causes clicking with fans
The best controllers are rather analog, and much more expensive too.
At least, that's what I always read. Exemple is Aquaero and T-balancer dropping from PWM to analog on last hardware revisions
Different fans like different forms of power delivery.
Some fan go berserk on PWM and others behave better than on an analog circuit. Most do better on analog but there are some that prefer PWM.
