Dear all,

How much does the ambient room temperature influence cooling and overclocking?

My PC is in a room with an ambient temperature of 19c. Does that influence over locking and heat? I’m air cooled at moment and am wondering if water cooking will make a difference ?

Thanks
 
Every Overclocking & Coolingdegree warmer the air is entering component coolers (CPU & GPU) is same degrees hotter they will be at same load and fan speed. It is not just room temp, but the temp of air entering components .. and that air temp in most stock systems when working hard is significantly higher than room .. it can eaily be 10c, 15c, even 20-25c hotter when both CPU and GPU are working hard in a case with poor case airflow.
 
I did a lot monitoring in march where the room was 65c, I did another test a few days ago during the hot spell where the room was 22c

The CPU and system temp were the same, I can't explain or understand why, everything else is the same

Lol sorry, 19c in the room, CPU 65c

Not sure how I missed that!

Were you controlling for fan speed etc? Genuinely accurate thermal testing is pretty difficult especially as modern CPU's / GPU's work so differently to older stuff in that boost clocks and therefore voltages etc are heavily reliant on thermals. You can see notable variance on a run by run basis with everything left on auto as the various logic in play pushes things slightly differently.

Thankyou.
If I take the case apart and have more “cooler” temperature on the components does this then make a difference ? The air entering the case or components would be similar to the air temperature.

If you remove the side panel and see temperatures significantly drop, that suggests you have an airflow issue with your case fans - check they're the right way around for intake vs exhaust, that your flow direction makes sense etc.

Same fans and fan speeds as I have curves set, same case, same location of pc, have a thermometer right next to it. Same game, played for at least an hour. Same everything other than the Ambient room temp

I honestly expected the temp to increase with the room temp but it was 65c, same as in march when the room was 3c cooler

Unless you're controlling voltages, fixed fan speeds, measuring power consumption etc then thats just down to variances with how things are boosting etc. If there have been software / driver / game updates since then thats also a factor.

The physics of it isn't arguable - if the ambient temperature increases then your theoretical operating temperatures increase accordingly. If they do not then there are other factors at play affecting it.

Must be that then, like I say I can't explain it.

What Sonic5W20 said sometimes works, but sometimes removing sidecover does not change temp of air entering cooler, and sometimes it actually causes air temp to be warmer. Best way to check is with a remote sensor thermometer like used in link below at end of guide to optimizing case airflow.
