i am atm using stock fans still, (just two that came with my corsair 200r)
however, my temps are really really low.
my CPU temps at idle is 30 'C min and 36 'C max
with my GPU temp at 28 "C min and 32 "C max
NOTE: (again, this is idle)
my room temp is ~~ 73 - 75 ' F
I watched a video saying that if you have your system temps to low, (compared to ambient temps) it isnt good, since condensation can occur inside the rig.
is my temps to low? and why is it so low?
Facepalm. I'm sorry, but no, you're not at risk for condensation. Show me the video please. I want to watch it and explain it.
To start with, 30-36°C is 86-96.8°F, and 28-32°C is 82.4-89.6°F. Look here: condensation is not possible when you are using air cooling or even water cooling. Think about it: do you get condensation with a box fan blowing directly at things? No, because it's absolutely impossible. Do you get condensation with an air conditioner blowing its cold air directly at an object? No because it's not possible (but if you took that cooled and cold object outside on a hot and humid day, then yeah you might see a little condensation on it).
Condensation is only possible if the object in question is so cold that it's either at or below the Dew Point (the colder, the more condensation is possible). The Dew Point is the temperature at which water vapor condenses into what we know as water. However, that doesn't necessarily mean that you will actually see water. It might only come in the form of a very thin layer, or "fog" as most people say, on the surface.
So, what are some typical Dew Points inside our homes? That depends on a LOT of variables, there is no typical Dew Point. However, I will say this: if you had a Dew point at 70°F or higher, then you'd say "holy crap, it's extremely humid". Any Dew Point up to around 55°F max is comfortable. As you go higher and higher above that, you really begin feeling it. Notice what I said there: anything up to 55°F. At a Dew Point of 55°F, the physical object would have to be at or below 55°F in order for water vapor to have any chance of condensing onto it.
With air cooling or water cooling, condensation is simply not possible, not even if you were using an air conditioner to cool your PC. Why? Because, think about it: you're blowing cold air onto warm objects. That's like taking a warm beverage outside on a cold day. Condensation doesn't occur because it can't. The physical surface is WAY above the Dew Point of that cold (and dry) air!
So, no, the only way you would have any risk of condensation is if you were using exotic sub-zero cooling like liquid nitrogen (LN2) or dry ice (DICE) or something like that. Even then, it's completely localized and you'd have the cooled area covered in insulation.
Finally, the reason why your temps are low is exactly like I've been saying all along in this thread. So, do you believe me now that you don't need to worry so much about your case fan configuration? Just enjoy your rig and stop worrying so much. I understand that you love it and you're protective, but don't take it to extremes like this. What you're seeing is what I've been trying to tell you about all along: good temps without doing anything about the stock case fan configuration.
Anyway, I still want to see that video. I suspect that even after this you might still be a bit concerned. Try to trust me: you have nothing to worry about. If you had something to worry about, then I would have said so from the beginning (and I'd be saying so now). ;)
