Question 1

Is this a good fan to use on my hyper plus heatsink in a push and pull configuration? Because I am currently looking for an led fan to be seen through the fractal Define R4 side panel window to match the blue led in the front of the case

Accepted Answer

I'm currently using 2 of these now in a push-pull setup through my first-gen h50 single-loop cooler to cool my E8400. Long story short, another cheap component in my case melted through the casing on the wiring and started a fire in my case, taking with it, thankfully, only the wiring to the fans attached and a sata cable.

I purchased two of these as a replacement for those fans and have no complaints at all. No issues with heat or airflow through the radiator, no issues with noise, and though I don't have a window on my case, the LED looks really good glowing out of the back of my computer cases. There is (or was) a blue version of the green one you selected but in regards to performance I haven't had any problems at all.

Question 2

Will these work as push pull for a Coolermaster Nepton 120xl?

Accepted Answer

I used them for push pull on a Silenx efz-120ha5. They work well. They keep my cpu about 36 degrees C. I have never used liquid cooling so, I can't say for sure, but it looks like they would work....

Question 3

Count you turn off the LED? Also how could you turn it on?

Accepted Answer

You can't turn it off unless u have a fan controller, and it comes on when u connect it and power up the computer

Question 4

Hello. Can any of you check this fan you have got and see if the green led can be disabled/cut without much work (meaning soldering/cutting/splicing etc)? or if it does need work, how much?

I would appreciate it.

Accepted Answer

It is working fine, rpm is always about 1900 - 2000

Question 5

is this a 3 pin or 4 pin connector fan?
