Difference between SP120 Static Pressure and SP120 LED ?

[Jacknif]

Hey, i saw that there is 2 version of the Corsair SP120 fans, one with a plastic rig and one like the AF120 with LED. I actually have 2 AF120 Blue LED fans and planning to buy another AF120 LED Double pack and some SP120 for my H80i but i can't decide between these : http://www.corsair.com/en-us/air-series-sp120-high-performance-edition-high-static-pressure-120mm-fan and these : http://www.corsair.com/en/air-series-sp120-led-red-high-static-pressure-120mm-fan-twin-pack

 

What's the difference ? :huh:

[Interfectorem]

The SP120 LEDs have a lower Static Pressure rating (1.46mm/H20) than the regular SP120 (3.1 mm/H2O).

One has LEDs, the other does not.

[DIV1D3]

One set has LEDs, and the other doesn't??

I'll check back with the CFM, dBA and static pressure. 

 

Edit:

The ones without the LEDs just have a higher RPM, which affects the CFM, mmH20 and audibility. 

If you have a rad that you are placing these fans on or in a restricted environment, then the ones without the LEDs will be ale to move more air, but with no restricts, or with very little restriction than an AF fan would be better. 

 

SP120 High Performance:

• 62.7 CFM
• 3.1 mmH20
• 35 dBA
• 2350 RPM
• 0.18 A

 

SP120 LED:

• 57.2 CFM
• 1.46 mmH20
• 26.4 dBA 
• 1650 RPM
• 0.26 A

Oh, is it important ?

Thanks c'ptain obvious.

Okay.

Okay.

Yes, if you're going to be installing fans on a radiator, you want the fans to be able to push or pull air through those tight fins of the radiator, so you want a high static pressure. Although I'm not saying that the SP120 LEDs won't perform well, I'm just saying that they won't perform as well as the regular SP120.

Okay.

Check my previous comment, I updated it, simply, the LED set can't move as much air as the other set because it operates at a lower RPM.

I would imagine also because of the different blade design the SP120 LEDs  have.

Would've thought that there would be a fin difference, as a lower RPM doesn't change the static pressure. Never noticed it. 

Or it does, I could just be spouting bs right now. 

 

Edit:

Just searched them both up, discovered that the LED version has 9 fins, whereas the standard ones have 7. So I'd guess that's what makes the difference. 

I don't have a Master's in Physics, so I have now idea what having less fins that are larger do.

The LED SP120's are effectively SP120 Quiet Editions with LED's. This means less static pressure and lower noise because of lower max rpm. The High Performance Non-LED SP120 has better static pressure, higher max rpm and they also sound like jet engines.

Wow, thank you ! But if i'm buying SP120 fans i'm going for the quiet edition one without a doubt , thx again for the detailed answer !

So Regular SP120 > SP120 LED

Seems like the SP120 quiet edition are better.

 

Thank you everyone

-snips for days-

Thank you everyone

No problem. 

I recon the standard ones are better than the LEDs, just because the fin design and the higher RPM (you can just make them quiet editions by adjusting the fan curve, afaik).

Okay thx

[jlim2]

one other difference is that the sp120 with leds don't have 4 pin pwm control so therefore you can't really manage the speeds without plugging the fans directly onto the motherboard
