#My 6900xt started going to 100% fan speed after I upgraded to a 7800X3d.

GPU usage hits 80-90% while CPU usage remains around 40-45%. GPU temps hit 70-80 degrees with hotspot temps up to 101 degrees. e.g GPU temp was 68 when hotspot temp was 101. I have the oc/silent switch on my gpu set to silent. Is the 68/101 gap between gpu and gpu hotspot temps ok? How can I fix this because it doesn't feel/sound right at all.

Set it to oc unless the fan noise bothers you to much then it should be better otherwise you might want to repaste the gpu

#

Though you might want to reinstall windows if it doesn’t work I’ve heard switching gpu or cpu can cause shenanigans

the gpu still spins up like a jet even when the switch is on silent

#

playing escape from tarkov puts the cpu at 40-50% usage, while my gpu goes up to 100% usage and hits the max junction temps of 103. is this bottleneck calculator wrong? low cpu usage with max gpu usage means the cpu is extremely capable of working with the gpu no?

Bottleneck calculator is 100% wrong.

#

Most of the time.

What cpu did you have before the 7800x3d? If you bought a new motherboard, you’ll need to reinstall windows.

(i hope) im reasonably experienced with pcs so all old drivers have been uninstalled, flashed the new bios, chipset drivers and i ran ddu in case even though i didnt change my gpu

#

the main suspect here for me is thermal paste drying up? its been 2 years and i also read many people having issues with temps specifically on this model (red devil) and having repasted multiple times

What’s your case fan situation

tawny tulip
#

performance is still great though

tawny tulip
#

i have the 3 front/diagonal intakes, and a 360rad on top exhausting air out

#

cpu temps are great even when playing cpu intensive stuff (tarkov) or running stress tests and benchmarks

#

You could try putting 2 on the bottom below the gpu

tawny tulip
#

yea i probably will

#

along with another 120mm exhaust on the back

#

Usually the gpu hotspot delta is about 10C different

tawny tulip
#

i guess i have to sacrifice clock speeds to lower temps for now, doesnt seem like its being caused by a certain setting/problem

digital willow
#

So if fans don’t cool it, you’ll probably have to repaste it

(Make sure it’s a good shop)
