Pros: - The form factor is this fan's biggest "Pro" / not many 140mm fans are 15mm thick if you haven't noticed, they are all 25mm thick. - The design It's slim, 15mm like a typical 120mm slim fan. - It had 17 blades and does move air rather nicely if used as a case fan. - I appreciate the blacked-out look, it's matte and looks good imo.

Cons: - The biggest "CON" is noise / it's wasn't designed to silent. - Not very good with static pressure - no RGB lighting (though some would see that as a "pro") - 120mm mounts holes

Overall Review: There are not soo many "slim" 140mm fans, maybe only 4 I believe, it's a design challenge. Prolimatech PRO-USV14 model is better in terms of durability I would say compared to its few competitors. I would like to see this design get updated, I would even suggest making it thicker if you have to, 17mm or so, if it helps with static pressure or noise. It's a simple design, minimal and I like it.
