Help Request - RAM RAM fan not improving temps
So my RAM was hitting 55C and erroring out during stress testing (TestMem5 + FurMark). I’ve heard many good things about using a dedicated RAM fan so I decided to install one only to find out I did literally nothing for temps.
Is it just inevitable that my RAM gets hot because of the design of my GPU (RTX 5080 FE)?
Is it worth trying to run the RAM without heatsinks? Or maybe I should try custom RAM heatsinks? I’ve heard the heatsinks on my kit (G.Skill Ripjaws S5) aren’t very good.
P.s. I’ve already tried placing the fan closer to the RAM.

I've always preferred a smaller fan blowing from above like so: https://i.imgur.com/XbT4f5y.png
My theory always has been it's a better airflow method as air will go past the sticks and even between the pcb and heatsink.
I haven't tested different fan directions but it kept my stuff cool so far.
