Review: a lot more quite than expected well up to around 3500-4000rpm - so far performance two minds but they seem ok, first of all when first turned on pc i could not hear them, they so quite i even went in to bios and downloaded software then had very close look with light and they were turning, so more quite than i expected, good to about 3500-4000rpm after that you really know they are on. so far i do like them but performance its hard to tell as they not only fans im running , build of them seems good, the price is good and power well it not to crazy , nothing like the 8k 120mm fans at nearly 30w each, these small fans use far less than that but still got a powered hub, reliability well not had them long but arctic they known to be pretty good but have used them for 8-20 hours at a time every day for around past 3 months they still seems good
Review: Very cool and quiet - Very cool

Very cool

### ⭐⭐⭐⭐⭐ Excellent fan for cost, airflow, and noise (lack of)
*by E***D on 19 June 2025*

Absolutely perfect product, easy connection design with a standard 4 pin pc connection, works very well especially for its size, it’s, 4x4cm front dimensions make it fit well with basically anything you could want it for. Additionally, considering it’s size and 6,000 rpm potential it can hit roughly 3500 rpm with very little sound, and shoves and impressive amount of air at 6k rpm
