New fan competition for Gentle Typhoon (Swiftech Helix) - Page 14

post #131 of 220
I think I'm still going to order 4 medium speed Yate Loons whenever Sidewinder gets them back in stock. Just for a personal comparison of noise/temperature/price.

Price/performance is the most important stat to me. Too bad the LED Yates perform so bad.

For the record I am not recommending one fan over another. Everyone prefers different characteristics and will purchase accordingly. The Helix has a lot to offer users, as does the GT and the Yate Loon.

I should get the Corsair SP120 Performance Edition High Static Pressure 120mm Fan and the Quiet Edition Saturday. I'll post videos of them in a new thread on the weekend.

Once that test is done I should have enough data to make my personal choice for my build.

Nice vid there Reglar !!! thumb.gif Amazingly enough I too did my own db test using an amazing iPhone app called Decibel Meter Pro 2 (DMP2) from Performance Audio. Actually I purchased their who package kit that had a variety of apps (7 in all) for only $1.99. DMP2 is great app and pretty accurate. I actually tested the Helix against two other fans; the Silverstone AP121 and Cooler Master Excalibur (CME). I have to say that although the the Helix did better in the db area, when it came to slightly more push, the CME did slightly better.

The clear winner though, when it came to channeling air was bar none the AP121s. I could not believe for a 1500 RPM fan how much air this fan pushes. It simply has to be experienced by testing them out yourself. Again, great test Reglar... smile.gif

PS - Hey Reglar, if I were to mail you two of the AP121's to set them up in the same config that you have could you test them? Let me know and I send them out to you. Of course I would need them back and I would email you a return USPS label so all you would have to do is test them. Doing a push config only probably wouldn't push as much air, but doing a Push/Pull (like I did in all my personal tests) is just amazing. Maybe doing two separate vids in a single and dual fan test would be a good idea. Again, let me know... Thanks, later... cool.gif

Special Note:

BTW, the reason why I tested out the CME's is because of these specs, (plus I have a custom made PWM fan controller):

Speed (R.P.M.): 600 - 2000 RPM ± 10%
Air Flow (CFM): 26.4 - 85.6 CFM ± 10%
Air pressure (mmH2O): 0.75 - 3.53 mmH2O
Noise Level: 13 - 30 dBA
Bearing Type: Barometric Ball Bearing
Fan Life Expectancy: 100,000 hours
Voltage: 12 V DC
Current (Ampere): 0.45A Max.
Power consumption: 6 W Max.
Weight: 127.8 g
Connector: 4 Pin
Warranty: 1 year

Here's the direct link:
Cooler Master Excalibur

When I saw the specs and then tested these fans out myself, I can say that even at 2,000 RPM these fans truly PUSH a lot of air; twice that of the Helix's, but they're noisy. So I brought them down to around 1850 and the db level was 1 to 1.5 db higher than the Helix's, so completely within toleration level. I'm still amazed that the way these fans are designed that they can produce air pressure of: 3.52 mmH20 at 2000 RPM. I haven't seen that in another 120x25mm fan; especially at 30 dBA. If it's out there please share it. Again, later...

So I take the verdict on these fans are that they are pretty decent and somewhat comparable to the AP-15s?

Something like that. I have been running these for almost a week now, but I think I am going to put my AP-15's back on.

@PunkNugget - thanks for the offer but I really just did these because I was interested in the Helix and wanted to see it against the GT. The last fans I want to check are the corsair's and then I'm hanging up my test rig.

Martin's roundup has the Excalibur performing fairly horribly in the noise/airflow department...

I guess when you compare them to the other fans that I have (the 8 x Delta PFC1212DE 120x38mm 1550-5500 RPM fans), anything seems quiet at that point... biggrin.gif and Excalibur fans really do push some good air at the rate of sound that is tolerable to me. Later... cool.gif

Just ordered three of these fans. Should be here halfway around the world in a week or two. Hope I won't be disappointed. smile.gif

You think these would work well with a Black Ice GTS360 Radiator? My Cosmos II doesn't have enough space at the top for thick rads, unfortunately (for such a MASSIVE case).
