High temps

[Joshua muldoon]

Hi, I’ve recently upgraded to a 3900xt. I’m having idle temps of around 60c and 70/80 while gaming. I’ve got a stock cooler at the min, case has plenty of air flow, and I’m sure I’ve seated the cooler correctly. Is there anything else I could do to cool it, or is the temp ok? I’m reading online I should be getting less. Thanks for reading

You need to get a decent cooler on that cpu, but you could also try to lower the vcore voltage.

Quick "rough and ready" way is to just set vcore to 1.2v in bios. Did that with mine and temps plummeted.

When mining with it it maxes out at 4000MHz and sits around 70c 24/7 but still hits 4250MHz in game with low temps under 60c

Your motherboard will be putting far too much voltage through it as they all see to do

They are warm chips though so best to spend some pennies on a new cooler

I’ve just ordered the dark rock 4 pro, hoping to see an improvement, in the meantime, what should I lower my voltage to? It’s currently on 1.375. Cheers

I also have the tuf b450 gaming mobo, is that good enough? I’ve got a 3080 on pre order also. Cheers

Try 1.35 first check temps then keep going down to 1.325v .

See what you get and let's us know.

I already put it to 1.25 and temp has gone down roughly 5/10c. That will do for now until the new cooler arrives on Monday. Just want this chip to last as it was bloody expensive! Thanks guys.

Is the motherboard good enough for the 3900xt and rtx 3080 do you think? Don’t wanna replace it really as I’m afraid I’ll mess it up

It only has 4 +2 power phases and the vrm can get hot according to some reviews. Should be ok but I wouldn't be overclocking the 3900xt.

Check out some reviews yourself then see what you think.

No I won’t be, I’m not clever enough for that. Thanks for your help

vCore is a massive issue and always has been with AMD. Even my 3600 was pushing 1.45 at stock. Currently running at 1.35 but more tinkering over the weekend should help.
I think I've had it at 1.25 but will play with the offset and see how stable it is.
