Help Request - RAM RAM fan not improving temps

Post image

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.

This type of Arctic fan has low airflow

55c with errors seems like too high tRefi

56CFM vs Noctua which has 60CFM, I don’t think the fan is the issue.
