Yeah, the Evolv X comes with 1200rpm variable voltage fans while PH-F140MP we can buy are 1600rpm PWM fans .. that is 25-33% more airflow/static pressure from real PH-F140MP. Considering PH-F140MP have simialr performance and costs less than 1/3rd what MLs' cost at £29.99 each against PH-F140MP 2-pack for £16.26 it's no surprise OcUK has a hard time keeping 2-pack of PH-F140MPs in stock. I'd much rather spend £8.13 than £29.99 for a fan.
Which MLs did you get, the 1200rpm or the 2000rpm models?
Sorry to bump this old thread, maybe someone is watching, but I have 2 x phanteks ph-f140mp's which I bought in china, as many say they are awesome, and were 5 quid in china, and they only seem to spin to 1350rpm. They do not have any writing on the sticker, just the phanteks shiny silver name sticker. I heard someone say before that the ones WITHOUT the naming on are the cheaper ones they put inside their pc cases, do you think I have those?
Also, IIRC, the packaging had written on them ph-f140mp @ 1600 +/- 350... What does that +/- mean? clearly its not they can spin over or above that 1600rpm number.
I have to say they are pretty silent even at 1350rpm, silent up to about 1200. I can heat the air but my nh-c14s is still cooking @ 85c whilst gaming... only 1 on there atm, in pull.
