Question Help with fine tuning my 7800 XT ?

[eXistenZ2]

Started on AC Shadows, moved in to medium settings to keep the 60 fps. However the heat was troubling me. Did a clean and repositioning of the tower, but it would still go up to 95C, with the GPU memory at peaks of 110C, which doesnt seem healthy.

Ive been tinkeirng along in Adrenaline, mostly with fan manual control (I tried automated/default undervolt, but it didnt seem to do anything noticeable.

What I am struggling with, is finding a balance between cooling and fan noise/levels. If I leave it on default, it feels like the fans dont kick in at all (audible) and allow it to go to 90+110C memory. When I take manual control, it usually has a few seconds at 100% and cools it off massivly and hovers at 51C-75C memory and no higher. Which I guess is a bit too cold compared to the fan noise? I wouldnt mind it being a bit higher if it was quieter.

From going by ear, it seems 1800 RMP seems to be an ideal middleground: audible but not intrusive. However,I have no idea how to make it hover around this. This is the current setup.

Any help is appreciated. Oh and if the whole idea is stupid, don't mind you telling me.

Describe your overall cooling configuration. Maybe that can be improved overall to help with this.

Are you OCing anything (CPU, GPU, memory)?

No not overclocking or anything. , standard settings. Deepcool LQ520

No front or rear fans? You need those to create airflow.

Typically, front, side, and bottom fans are intake.

Rear and top are exhaust.

What direction are the fans on your AIO moving air? In or out of the case?

 

[eXistenZ2]

Yes, the top fans are exhaust.

i was contemplating some additional fans, but what more puzzling to me is why the GPU fans hardly do anything on factory/default settings when i hit 90C, but when I tinker a bit with it, they kick in (audibly) at 50.

Im just trying to find a bit of balance and understand the numbers, cause I dont think the add up/are properly represented. For example on default setting my gpu was at 70C, i take manual control and I get a full blast of 100% fan speed, despite the graph indicating that 100% fan speed is at 80C. But then why doesnt it do anything when its on default setting when it hits 90....

The VRMs are getting very little airflow (all that stuff around the CPU and even the memory). All this impacts how the system performs and even cools itself.

I strongly recommend improving your airflow.

At the very least, install a 120 or 140 to the bottom front and behind the cooler in the case. With noise concern taking front seat consider things like Noctua or be quiet! Silent Wings fans, or others advertised as "quiet" fans. If those are price prohibitive I find that Arctic makes a good value fan.

Yes I will u^grading with some fans, but what settings should I tinker with in the meantime?

Like for example,I just set the fans to kick in with a bit lower speed at P3 while raising the temperature, yet its going faster on the same temp...
Like for now, the temp is 51/75 while gaming, and thge fans are close to 100%,; which they should only be on 80....

And to reiterate my question, why dont the fans kick in at all with default settings?

Get the fans. Then tinker.
