It looks like Noiseblocker NB-BlackSilentFan XL2 120mmx25mm as one above says here, these fans are not so quiet as advertised nor are they special effective.
You can get any color you wish by buying some types of Gelid or SilenX fans - and paint the impeller yourself since you can take off the impeller. I have done this on SilenX led fans - and white does really look good
And simply swap the fan blade assembly (super easy to do)
I would email jabtech and confirm that the motor diameter is the same size. I know the JT black low speed fans are hit or miss on motor size, it seems like they use a smaller motor now adays, i dont know about the LED low speeds.
I have to put in here : sleeved fans do start at a lot lower current than roller/ball bearing fans - but they dont live as long as roller/ball fans
You will need to change them more often - and they are more quiet in their lifecycle (which is half of the bearings - they only cost the half too)
Yes. Like I thought
thease fans are a bit of a puzzle to figure out what they really are
they are not yates nor noiseblockers or Apevia or scythe or xigmatek
you guys are close but not the right answer yet lol
