120mm 2000 RPM fans longevity and durability?

[kingknightrider]

Been using these -WITHOUT a Fan controller:

Cooler Master SickleFlow 120

https://www.amazon.com/gp/product/B0046U6DTC

Using 3 pin to 4 pin MOLEX adapter on these...so 100% speed is that right and true???

 

Am I even actually getting 2k RPM?

Or is a fan controller actually necessary to get the 2k or is the SF just fine and I am already getting 2k RPM?

That said do either of these fans below push more CFM than the SickleFlow -again WITHOUT using a fan controller but by only using the 3 to four pin molexs' adapters?

 

Noctua NF-F12 iPPC 2000 IP67 PWM

https://www.amazon.com/dp/B00KFCRIQM

 

Cooler Master JetFlo 120

NOTE: I don't really care sound level -just durability and longevity at a constant 2k RPM.

yes

plus or minus 10% due to manufacturing differences

Yes if there's no obstacles for airflow

This is a relief.

And if there is obstacles is one of the other two better than the other or is the sickle flow a better choice in that condition?

Those other two are no good as fans with a filter or is it the opposite and which if so or is one good and the other bad?

the Jetflo is the problem, not enough static pressure for pulling air through obstacles.

I think every fan life span rating is rated at their maximum speed.

Ok.

Kill it with a vengeance.

So now between the Noctua and the Sickle Flow then -which is better or are they about equal in CFM?

Also is the Sickle quieter than the 2k Noctua or vice versa?

 

Would either of those work well in the filter category but also work good for say the same thing I did before with fans on the graphics card or one for filter and one for the graphics?

 

My new card I am going to rip off the shroud and stock fans and put two 120mm 2k fans on it and have system fans be 2k as well go equal across the board in the new system... or would that break the new cards' heat-sink.... considering its counter part has two 1.5k RPM Noctua's on it now though seems just fine since install late last year.

factory ratings are up in their sites

doubt that, but both will be loud. Noctua does ship fans with slowing cables though

What cables?

Never seen a slowing cable... does that come specifically with these higher RPM fans?

 

That said it does look like there is a trade off...

10 more db and 1 more complete static pressure for Noctua vs the Sickle flow:

 

Noctua

29,7 dB(A)

150,000 hours

3.94 mm H₂O

 

Coolermaster Sickle Flow

19 dB-A

50,000 hours

Air pressure (mmH2O)2.94 mmH2O

The LNA = Low Noise Adaptor, this short cable/adaptor usually is being included in Noctua's coolers package, not in individual fan package. The way it work is only reducing the RPM by some %, not reducing noise while it still run at rated max speed, and I think it's useless because we can play with fan curve instead..

Though using fan controllers?

That is something I would like to be avoiding in this new build...

It is going to be fan overload on steroids... this current system has 15: 5 intake, 3 exhaust, 3 cpu and 4 graphics card.

If I have my calculations right will be over 20 in the new system: 6 intake, 4 exhaust, 3 cpu 8 graphics card.

So many fans don't really want to mess with a lot of controllers.

So will just go full blast.

No you can hook them directly to the molex connector, just like how the sickels are
