Noiseblocker

[JAKEBAB]

just wondering has anyone used Noiseblocker NB-eLoop B12-1,2,3,4? dont know the difference between them except rpm which i dont know what rpm im suppose to get and wanted to know like the quality of the fans if they are quiet or anything?

 

thanks.

The difference is speed rpm means the speed

[everything count to life]

And they are pretty quiet and perform really good.

i know but what rpm am i suppose to have like i know faster is louder but if i get 800rpm arnt they going to be bad for rads? what rpm is used for what purpose?

It depends on your rad some rads support high speed and some support low speed

I have 2 b12-2s and 3 of the slower PWM version (forgot the model name)

 

I run them very slow (5v for the b12's) and they perform ok fon my rads.

 

Haven't really tested them at high speeds because my temps are fine.

ive run the 140mm (non-PWM) versions and they are quiet. fair amount of air,

usually Noctua F12 expensive or more.

depending on how well built or planned the rig is usually can dictate a fan range.

 

if using for radiators, the radiator mannie usually has a fan speed range for the use

of the radiator.

5-12 fins per inch 600-1000rpm (alphacool, XSPC RX-series, HL Black Ice SR1, phobya v1.1/1.2)

12-20 fins per inch 1000-1800rpm (magicool/colgate 180-200 rads)

15-25+ fins per inch 1600-2500rpm (koolance, swiftech, XSPC EX-series)

ok thanks and what about volts when people say i run my fan at 5v and 12v i know thats how much power but does that lower and raise the rpm? and how do they do that like what do they do to control how many volts? fan control? ive only seen a rpm fan controller sorry im a noob with fans :/

most all fans are "rated" on output using 12v.

i use a simple multiplier to factor/estimate fan performance

take the 12v stats and multiply them by .58333 and this gets pretty close for 7v stats

take the 12v stats and multiply them by .41666 and this gets pretty close for 5v stats

 

to use 5v i use the PSU molex/SATA connector and use that powerline (red in color).

to use 7v i use the PSU molex/SATA connector and use that powerline (red and yellow in colors).

you can use supplied voltage adapters (inline resistors) to cut the voltage from 12 to 7 and/or 5v.

the 7v adapter is known as a low noise adapter, Noctua sends a 5v call Ultra Low Noise adapter.

 

another way is using a fan controller or the motherboard fan headers can control the voltages or

PWM cycle rate. not all motherboards have this function, but anything sandy/ivey bridge or 870

or better can alter fan speed via BIOS or 3rd party appz.
