Am running a xspc rs (I think - came as part of a xspc kit which is no longer available) 360 with 3 Apache fans blowing through - PWM controlled.

Fans seem decent enough but are there better ones ?

n.b. Am cooling an i2700k clocked @ 4.6 and a 7950 at stock.
 
Scythe Gentle Typhoons

Best performing fans for radiators. They're not PWM though so either need a fan controller or your motherboard needs to be able to control speed of 3pin fans. These things don't need to be run at full tilt, but it's nice to have the overhead to do so.

Thanks but would prefer PWM - takes the guesswork out of the correct speed setting :)

Don't mean to be rude, but I think you might be mis-understanding how the fans work, regular fans power controlled by the motherboard appear to the user exactly the same as PWM fans controlled by the motherboard do, you set either a fixed speed or a dynamic curve according to CPU temp and it's taken care of.

The only real difference is that power control via motherboard controls the power to the fans and thus their speed, whereas PWM rapidly switches the fan on and off (reducing its speed by crippling its ability to run properly), between the two power control is by far the superior method as PWM results in a ticking sound at certain points in the speed range (where it is differs depending on fan model and loudness depends entirely on how good the user's hearing is).

In short PWM is what you use if you don't have the ability to do power control as most boards have PWM but not all support power control, if yours does it's better going that route imo.

Did find the last bit a bit insulting but am old enough to get past it and concentrate on the actual information given. :)

I am not an electrical engineer but having now read up about PWM and power control (my Asus Z77 Sabertooth came with AI Suite 2 which btw I do use to control the 2 35mm motherboard fans ) do believe that I do now have a better understanding.

I was recommended PWM control for cpu cooling fan by one member or another from this forum and very much appreciated the advise. As I did not wish to spend lots of time trying to set a fan profile when I had no idea what would be appropriate for my cpu I was thankful that PWM (Asus motherboard) control solved this problem for me.

Having read up - I am still of the same opinion , so will stick with such.

I was and still am looking at the Apache fans that I have blowing though my radiator (as they are a few years old now) and was looking for input from others as to what might be classed as 'better' fans.

I did look at the Corsair SP Performance High Pressure fans but was a little concerned that the fan speed/noise might not be acceptable (I do like quiet!).

Would still appreciate any opinions ref alternative fans :)
 
Enermax Magma maybe?

• Flow (CFM): 69,15
• Flow (m³/h): 117,49
• Pressure (mmH2O): 1,4
• Noise (dB(A)): 18


Either way you need high Air Pressure for watercooling, and they are pretty good.

They do not beat the SP120 @ 100% fan speed (3.1mm H2O) but, if you can live with a vacuum cleaner next to your ears, pass.
While the Corsair AF120, are only ~1.1mm pressure & 63 CFM and still loud (30db).

Buy the quiet/low noise editions then. AiSuite will calculate the fan profile and you can set it to run in silent mode anyways. AiSuite will probably turn the bloody things off in silent mode!

I use AiSuite and used to run a SP120 PWM Low Noise High Pressure before replacing it with a GT 1150, I still have it's curve data in an old screenshot:

100%: 1377RPM
90%: 1265RPM
80%: 1088RPM
70%: 892RPM
60%: 726RPM
50%: 574RPM
40%: 422RPM
30%: 417RPM
20%: 407RPM
10%: 416RPM

With the profile set to turbo it hits 50% at 40c, in silent it hits it at 50c, it's still quite noisy at full whack but never used to get anywhere near there, couldn't really hear it airflow wise but the PWM "tick" became audible at ~60%, however at that point the heat load was being caused by gaming which meant noise so pretty much drowned it out.

Pretty good fan.
 
I think I'm going to use NB eloops for my 360rad, i hear GTs are the best but ill sacrifice a bit of performance for looks i think - Adam
