Discussion Lian Li 011 Mini VGA Position

[acrvr]

Hello,
I just finished moving my system to the 011 Mini. I find having three fans at the bottom feeding air directly to the GPU helps temps a lot.

At the moment I have the motherboard placed in the middle vertical position. The VGA card is being cooled nicely, and there is some distance between the VGA fans and the bottom case intake fans.

I have the option of moving the motherboard even lower which would put the VGA card almost touching the bottom intake fans. Would this result in better temps or the opposite?

Thank you

Generally you'd want a small buffer between fans because they'll often cause noise with turbulence because of difference in air velocity and pressure, or so do I think is what's happening. A person with actual knowledge of aerodynamics might correct me on that.

So either have the GPU as close to the ventilation holes as possible, or have some space between the two types of fans. A good starting point is a fan's thickness between them. I believe @Necere did research on this topic but with the amount of distance between fan and a solid surface needs to allow proper airflow.

I can tell you from experience at least in the Nr200 and 1 other case (name escapes me), fans on the bottom touching the card, resulted in worse temps than leaving the bottom fans out, and the GPU to pull it's own air in.
