In old continent, in Europe there's new fan's in market at least in baltic and nordic countries: GreenClimber fans. Some say its Nexus GreenClimber even they are Eolo 120mm. However that would be splitting hair since both are re-branded YL's. D12SL-12 is GreenClimber 120mm's name. Same as nexus. Fan is identical with NExus Real Silents with except of sticker and fan color: Its bright green in 120mm version.
So nobody probably is not surprised when I say after testing fans they performed identically with-in sample variance. Same RPM's, same noise charasterics as Nexus fan I used in reference. Its a same fan, different color and different name.
So what's the difference? MSRP. In Finland Nexus fans sell's 7-11€ depending where you get them, sometimes nearly 20€'s. greenClimbers: MSRP 5,50- 7,50€ in Finland. They are considerably cheaper than Nexus fans but also have nothing but the fan, like old Nexuses back in days. No silicone mounts or fan screws.
I got 80mm GreenClimber too, but I don't have reference Nexus yet. However its all black and not green (which is same, I really do like this green shade) but it too is YL model but I'll let you later know how it fares. I expect to be pretty identical with Nexus RS 80.
