Screws are a bit tight because of the plastic but dont mind applying pressure.
- Use the adapter if you just want light air flowing in/out of the PC.
- Don't use the adapter if this is your main case fan to blow the hot air out, and keep it cool.
- The blue light is great! :) Mine gets mixed with CPU's OC(Red), and it turns Purplish Red.... killer ambiance!
Hope that helps.
They DO have enough airflow for water cooler.... Maxing out at 1800-2000rpm with reasonable sound levels.
*Technically NOT a 'SP' fan ... But does perform just fine!
The lighting is a little on the weak side, don't expect it to shed light more than themselves.
Has 3-wire main board header connection; comes WITH Adapter for 4-wire power supply connection

To make it less noisy, just install the resistors, but you will get less air flow.
When I do 3D renderings, my enclose temperature raise to over 40C. I want the heat out. That should do it.
Get in some resonance frequency at slow speed (pwm) but is to be expected. (the nature of PWM)
-Light look really nice for a cheap price and match the rest of my desk set up.
-EXTREMELY loud. Had to return it. It was an absolute deal breaker for me. I do not keep my PC in my room, so sound usually is not a huge issue, but I could often hear these fans over my headset while gaming/listening to music/watching videos at 30-50% volume. This is completely unacceptable to advertise these as silent.
-Short motherboard cables, pretty much forcing you to use the molex connectors as no way these were reaching the motherboard fan headers from the front of a regular atx case. This probably had something to do with the sound as well as they were probably running at full speed, but it was pretty much impossible to control the speed with how short the motherboard header cables were. My white LED fans that came with the case are 10x more quieter and still using molex.
-Ontop of them being loud, they really made no difference in air temperatures inside the case.
if you want green LED fans, it would probably be more worth it to buy high quality RGB fans and change the colour to green. I am usually okay with cooler master's sound but these made my computer sound like a jet taking off at all times. Definitely would spend the extra $20-30 per fan on the higher quality RGBs.
