Pros
- The Silverstone FM121 is a very good fan indeed.
- Very stylish and clean design for the white version.
- Includes a complete set of connectors and are given ample length for each.
- The bundled 3.5" bay single-fan controller is very useful and gives one control of the fan's noise and performance level.

Cons
- Pricey.
- A bit noisy at full blast.
- Air pressure's a bit low at lower speed levels.

Suggestions

Using the fan at around 65-75% of it's rated speed would give the best noise-to-performance ratio. Good enough to cool an overclocked system while keeping noise to a minimum. Going lower than 65% makes the fan's performance suffer greatly and higher than 75% makes the fan a bit noisy.

One caveat though, you'll get 75% of the fan's speed at roughly a 30% setting of the rheostat. So experiment with the rheostat well.

Hey there, I'm PMAer from TPC ;)

Well, the comparison vs my fans, i posted a graph in my post prior to this..

" 1. Performance vs other 120mm fans"

I haven't tried running the BT with all my 120mms though, since that would take some time.. hehe.. I just used whatever was on my pc desk at that moment..

For my full list of 40, 80, 92 and 120mm fans, just click here:

1.2k pesos for a fan? yes its stylish but in the long run, it will still gather dust ruining the cool white finish,,

Anyone know where i can get a similarly powered fan ( with speed controller also ) for a lower price ? these fans are actually priced only at $11.99 w/o shipping costs so thats about Php650

@Rpgn what triblade fan do you have? how much cfm ?

@Demo: Uhm.. the Silverstone FM121? Only abroad afaik, US and Europe predominantly..

I have the 120x38mm Nidec TA450DC 0.80A 4,050rpm 130cfm Tri-blade for 450 bucks + the connector.

Im also bringing in it's little brother, 0.49A 3200rpm 110cfm in about 2 weeks time.

Here's a partial pic of it on the Big Typhoon using buts and bolts (c/o dulber)



I've since used normal screws to secure it since i found the right-sized ones about a week ago.

@Demo: Ah.. for the prices i've posted (400+ Php), they don't come with a fan speed controller. The buyer has the option of getting a 3pin or 4pin connector to go along with the fans.

I've posted them in the Black Market btw:
