My only gripe here is the price for what you get, and hence why i've dropped a star.
They're not priced all that much cheaper than the full size 120mm fans.
A bit expensive but well worth it.
Shipping
And voilà—the nas is back in service, and peace returns.
Packaging/appearance
The packaging and instructions were great and came with numerous cable options.
Packaging was great, every extra you need and really good instructions.
Excessive packaging, i object to high levels of non-recyclable waste.
If it wasn't for its reverse polarity protection, this fan would've popped and let the magic smoke out.
Competitiveness
I have a nvr which is used to save cctv recording from hikvision.
Only a little better than my gelid ones, so compre prices.
Overall, the nf-a4x20 flx is a top choice for anyone seeking a reliable and silent cooling solution.
