LF two 140 mm fans for Fractal

post #1 of 5
Thread Starter 
Hey Ocn,

Recently got myself a MSI gtx 580 Twin Frozr II and my case needs some airflow improvements.

Seems the best temps I was getting was 70C when having a fan blow with 70 CFM from the side intake and have one added 70 CFM blowing out the top. Also have two fractal 1000 rpm as front intake and Antec CPU cooler as back out.

Now I was wondering if any1 could recommend some 140 mm fans with the possiblity of 60-70CFM, can fan control them.

I do like quietness from my PC, currently tried seeing the best airflow with 2x 120mm cooler master sickle flow, but when I have the sickle flow as a sideintake it WINES insanly hard. Only seems to do so as intake.

Anyway I was looking at the Noctua, but they are pretty expensive worth it ? when you can get 140 mm Scythe Slip Stream 140 SM1425SL12M for less then half that money of a noctua.

Noiseblocker has it's 140mm PK series in varying speeds. You can get them in 700/1200/1700rpm variants. They can be mounted any which way but are expensive.

The 140mm Scythe Slipstreams are great (I use the 800rpm version) but don't mount them horizontally. (Sleeve bearing)

The TY-140 moves a good amount of air, can be mounted any which way and should be fine with fan control.

The Thermalright X-Silent 140 is quiet at max speed but I don't think it'd move quite as much air as you'd like and shouldn't be mounted horizontally.

The Enermax T.B Silence 140mm can be mounted any way (Twister Bearing), is quiet at max speed, and moves a reasonable amount of air.

You also have the Scythe Kama Flex (135mm technically) line but they're getting hard to find and arn't suitable for horizontal mounting.

Just to give you some ideas.

Good to know which way fans cant be mounted any direction.

I Like the Thermalright TY-140, cheap, moves alot of air and is quiet. Just gonna figure out the exact specs since some websites are usually wrong.

I have lots of Noctua's that I have actually removed from my case. To risk a heresy, I think they are crap. Pure and simple. Noisy, overpriced and not very effective. The best 140mm fans seem to be the TY-140s, of which I have three on the way. I've tried the Akasa Apache Blacks, which on paper look good, and seem to be marginally more effective than the Noctua, but nothing to remark on and the 140mm gets really noisy as it spins up to max rpm, which on my fan is around 1450 rpm rather than the advertised 1300 rpm. I also have one of new Scythe Slipsteam 140 PWM fans on its way to me for testing (it's the same one that goes on the Kama Grand Cross cooler, not commercially available as a standalone product). It's promising from what I read. Wish I could lay my hands on more of them

Enermax TB Silence run at 750 rpm, too slow for much oomph. They are very quiet, though.
