I was looking for a replacement fan for my Shark. This is it. Quiet with good CFM. I run 9 fans in my desktop at very low speeds to keep the noise down. These are the quietest I have found while providing good airflow.

Purchased two of these to replace the stock fans on my Enermax Ostrog GT case. They arrived in perfect condition and exactly as described (on both Amazon and Phanteks products page - do you research folks). To be clear, these are 140mm fans which can overcome high static pressure. They are good for radiator work and in areas such as front case fans that are typically installed in front of hard drives/hard drive cages.Both of them fit perfectly using the same screws that held the stock fans in place and do their jobs in providing fresh, cool air to my CPU/GPU. They completely own the stock Enermax fans that came with the case. I've seen a 5-9°C drop in CPU/GPU temps under load and it keeps my case cooler in general.As far as noise, I have noticed a bit of an increase over the old Enermax fans, but that is to be expected as they're pushing more air through the case. I don't notice them at all when gaming but the background noise they produce may bug those who seek silent PC builds.

Was a good fan. I however needed 4pin. This was 3. I bought it in a hurry at work. Was my own fault.
