PC temps vs environment temps

[Hans Power]

So, I'm German and in Germany we sweat like real men during summer - and so do our PCs. What I'm trying to say is that we don't usually have ACs in our apartments so PC cooling needs to be able to deal with that.

My question: Is there a ratio on how PC max temps (mainly CPU and GPU) rise relative to environmental temps or is it just linear? Like if my apartment temps rise from 20°C to 30°C, will my GPU/CPU max temps also rise by 10°C (I don't believe they do cause I never got that high temps in my PC)? Is there another rule of thumb?

Should be quite linear. If some component gets overheated good idea is to under-volt either CPU or GPU. But in regular usage even that's not really needed in my experience (since I under-volt everything).

From my experience it does, but not significant

In my area, it's around 30-ish degree Celsius at noon, and at night I turned on AC at 26 degree (tropical area with high humidity, so no 4 seasons such as spring nor winter)

The difference of CPU and GPU temp when I game at noon and night, is probably around 1-2 degree at max

 

P.S.

Currently it's a huge heat wave in the place I live, where it could be 39 degree or on some area go as high as 42 degree. But my rig doesn't seem to have overheat issue till now

 

The most important thing is, to make sure that your PC has good airflow from intake to exhaust

If you want a better temp, just remove the side panel glass and the temp will drop quite significant especially on the GPU, but you will risk some dust to get into your rig

I would say this.

 

In my case, I do not remove the side panel as it interferes with my case flow on both my Meshify C and Torrent C.

 

Good fans are... good

It's essentially linear, +10C ambient = +10C  on the CPU/GPU etc

If you have no A/C (sure it's rare in Europe), an apartment fan can help the airflow  in your rig

1 c ambient temp is 1c to pc temp its a 1 to 1 so lower ambient temp lowers pc temps.

other things that help with pc temps is air flow and water flow and surface area.

the higher the ambient temp the less cooling each will do. some case it you might still thermal throttle

It's often said removing the side panel is not as good of an idea as was thought... as is does break the flow of the air often times. I'd vote against side panel removal for temps, it might even get you worse temps at the end of the day. Not to mention, your case will become a dust nightmare in no time.

removing the side pannale is a test to see how bad of air flow the case has and how much the temps drop. in a good air flow case having the side off is not needed. but most likey will improve temps even in a hi flow case. (because of hoe the gpu exhaust its heat to the side)

 

also to see if the case is the problem or hardware like if you remove the side and gpu temps stay the same meaning some other cooling problem. like past or pads or fan rpm.

 

and its free to try...so...

It is not linear. The hotter your room gets, the more you'll struggle to cool your PC and it'll heat up faster than your room.
