I've owned a 7800x3d b650 tomahawk rig for a year now,
I started with corsair 2x16gb ram but i replaced them shortly after with g.skill trident z5 neo rgb cl30 6000mhz 2x16gb ram.
The ram works perfectly w/ buildzoids timings which is great because my ram knowledge is zero, I've always just enabled xmp/docp and haven't a clue where to start with manually adjuisting ram w/ timings.
The cooling however, it's terrible, corsair ran at least 10c cooler from memory, but i noticed my g skill ram hitting 70-75c during tm5 + occt for a gpu+ram workload.
I have since been using a 2x40mm fan mount on the ram and temps dropped at most 10c.
I attempted a 120mm fan instead as i read someone kept their g skills ram down from 60c to 40c with one, it resulted in the same temps give or take 1-2c.
I learned g.skills, the brand everyone hypes about with ram, cheaped out on the pmic this time and didn't cover it with anything, causing these highs temps.
Unsure why everyone suggests g.skills ram when all their ddr5 lack proper cooling on the pmic this time around though.
I do want to note; I've not had any issues with stability yet regarding the ram, however i have seen the ram between 55-60c hosting servers + gaming at times. I know most people try to stay below 50c and if the pmic is averaging 50c at all times, i figured it isn't good long term.
Now i've got two options;
- remove stock headspreaders, apply my own and apply thermal putty to the pmic
- replace the ram with better ram
I would do the first step but i haven't a clue how to apply/use thermal putty, is it simply like paste? And what thermal putty should i use. If i did do this, i'd do the heat gun method.
The second option is to replace the ram;
I wouldn't mind going 2x32gb but i am struggling to find cl30 6000hz ram for this, I was looking at tgroup since i know they have good ram w/ pmic coverage but the stock in UK is so limited and i could only find cl34 or cl38.
The reason for 2x32gb is because if i'm replacing the ram… may as well upgrade and i do host game servers which sometimes has gotten into the high 80s / low 90s on ram usage, (i also play on the same pc).
Any recommendations on the steps to go with? I'd like to use buildzoids timings but i may tinker with the ram timings in future, i just find it very overwhelming with all the different sub timings.

Poor quality but it should work, i don't think cooling should be an issue.
Don't have a pic of the 120mm fan but i had it directly on top of the ram and central to the pmic.
Also side note, do your own testing because i also read turning off the RGB had big effects on the temps and when i tested the ram /w rgb off, it changed 1-2c at most.
