How Much does Room temperature Matter?

[Guest]

I am building my first ever PC and u want to know a tip for overclocking. My room can go down to as low as 15 C° in the winter and as hot as 25° in the summer. Will that affect the CPU and GPU temperatures drastically?

[Oshino Shinobu]

It will affect them by a minimum of 10C (from 15C to 25C). Basically, the cooler ambient temps are, the cooler your components temps should be. You can never go below the ambient temps without active cooling (physically cooling the components, rather than just transferring heat away from them).

 

As for how much it affects clocks, it can depend on the individual part. Cooler temps don't certainly mean better clocks.

These temperatures won't affect your PC at all. Just ensure that you have balanced airflow in your system (number of intakes roughly equal number of exhaust) to keep the hot air out and enough fresh air in.

[Captain_Chicken]

Not really.

It will be affected, but won`t be really noticeable

yes, it does affect it quite a bit, but my room is normally in the 28-30 degrees Celsius range and i can OC good enough lol

The room temp is the base temp for which your system will operate.  If your CPU idles at 50c in the summer, while the ambient temps are 25c, then in the winter, you can probably count on having an idle temp of 40c.  (Room temp +25c).  Just an example.

Your CPU & GPU will run hotter than the ambient temperature of your room under any kind of load so in reality even the ambient room air will still be cooler than the component its cooling.

In reality it makes very little difference unless your ambient temperatures are extreme.

when i brought my PC up to Georgia it was much cooler there than here in south Florida and my idle temps were more around 20 rather than the 35-40 in florida. in the summer an idle of 50 sometimes too

lol, sometimes it's hard to believe this is a pc tech forum.....   :blink:

his room temps aren`t that far apart though and 35-40 is really, really high

i know. it sits around there. my room temps are very high.

aint nice for your PC, but for the human body? seems like heaven

10c is 18f difference in room temps.  15c is quite chilly.  25c is comfortable in the summer though.  The difference in those temps WILL affect system temps....measurably.

[Joegeddon]

Air cooled PCs can only be as cool as room temperature, they will never reach that level so it doesn't really matter. The only way it matters is the room will be a bit hotter which may annoy you.

pretty much

But I meant to say that he won`t really notice it, temps changing is also measureable, for normal use? not noticeable. It`s not like he`s gonna go hams on OC`ing

10c when overclocking is a HUGE difference.  "hams" or not.  lol

Have you actually tested this yourself? While yes, 10C is huge difference in temps. But if you OC with air cooling when ambient is 15C, you can still only go so far before volt limit and silicon lottery comes into play. And 10C raise in temps after that OC isn't going to do much. 25C is quite normal room temp. Under OC stress testing you go up to 80-90C. In gaming and high CPU loads, real temps are still under 75C. So ofc if you run stress test in summer and winter, you can go further in winter. But in the end it doesn't matter for CPU temps when using it in normal situations.

He asked very specifically about overclocking, and if the difference in his room temps would make a difference.  The answer, very simply, is YES.  Ambient room temps are the base temp for your system.  It's where everything starts.  If you start higher, your peak temps are going to be higher.  If you start lower, your peak temps will be lower.  This is pretty easy to understand.  lol

I wasn't arguing against that. But way you put it and way you use "lol" at end of every post makes me think that you either think this is just stupid question with obvious answer. Or that you just plainly don't appreciate others.

Probably a little bit of both.....

TlDr; yes, you can't cool a CPU below ambient temps on conventional cooling (air or water) unless you have LN2 and a chiller connected to your CPU loop or even phase cooling.

I prefer to call it hell, with a room temp of 30c I can't sleep at night
