What type of fans are these?

[Ehrix]

I’m wanting to get new fans for my old pc to sell it and I was wondering what type of fans are currently in the pc so I can get the correct fans. Example: are they High airflow fans or Static pressure fans?

high airflow. many, thin blades.

 

whereas static pressure has less blades, fatter and a sharper angle

[DailyProcrastinator]

High airflow, more skinny blades with larger spaces in between.

Just give them a good cleaning and leave them. You won’t get the money back from the cost of new fans. If the prospective buyer isn’t a fan affendicio they will leave them in. If they are they’ll just replace them to suit their preferences (some thing in an Austrian Tan with chocolate Corners perhaps?

AMD and nVidia fans, but we don't usually talk about it as it leads to unpleasent arguments

(also high airflow, and I don't think changing the fans will do much unless you get LED fans to appeal to GAMERs)

ummm??

 

those fans are closer to static pressure than airflow....

 

probably a hybrid/multi purpose blade design.

Noctua's Redux fans are purely airflow, yes, but to scale as that is a 92mm fan that is sitting beside a small 80mm fan. While taking a second look I would agree that they are likely optimized for a happy medium between airflow and static pressure, but they are not static pressure fans.

 

Here is a better visual example. 

 

Air Flow:

 

Static Pressure:

I did clean them, though one of the fans makes this annoying noise which bothers me. I might as well just keep them to make as much profit as possible.
