Default What do you think?

In theory -

Background:
Our body generates heat; and our skin regulars the body temperature acting like a heatsink.

Condition:
Standing outside a building or house under calm condition (less than 5 Mph wind) in the shade versus standing inside a building with two windows and two fans directly opposing each other and blowing at the same direction at about 20 mph.

Question:
Do you feel cooler in the building or outside?

I think that depends what's the temperature.
My guess:
If the temperature is the same I think it might be colder inside.

Same temp condition Different wind speed.

more wind = feel colder

More wind = Feel colder = heat being removed from the skin = heat being removed from heatsink = higher thermal loss of any thermal generator

Put your hand in front of the intake fan of your PC; your hand feels "colder" from the draft drawing heat from your hand.

Put your hand in front of the exhaust fan; your hand may feel warmer; air blow across the case absorbs the temp from heat generator(s).

Just an 80mm fan will provide ~25-35 CFM; 2x80 = ~50 to 70 CFM in a case that is much smaller than a room; I have not figured out the velocity but it will certainly be higher than say inside a room where there is no wind speed to speak of. Otherwise, paper will be flying around.

Bottom line; a well vented case is far more efficient than open case.

obviously, but an open case is easier to work with

Only if you need to test 50 heatsinks in a year

+ upgrading Vcard monthly
+ removing HDD out for "cleaning"
+ replacing power supply regularly just for fun



It serves no other purpose except "looking cool" in front of your peers and endangering yourself and others in the same room.

If my kids use open case PC, I would have asked them to move out before the house gets burnt down.

I recently bought a new case (Thermaltake Soprano) which has 2 120 mm fans and 1 92 mm fan. Still the temperature is 4-5 higher then when it's open.

It seems I got to reorganize my cables, I think.
