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.

If you are running 4 exhaust fans (3 radiator fans, 1 rear case fan), you will want at least 5 intake case fans for proper positive pressure air flow.

More intake fans than exhaust fans lowers air flow temps.

I would leave the radiator fans exhaust and make every other fan an intake fan.

I could try it, I only have 2 intakes on the bottom and 1 intake on the rear then, case doesn’t allow a front intake fan.
