quick case air flow question - Page 2

post #11 of 15
well with air cooling i doubt you will get any better, there great temps for air imo. but i spose the bt mod will is worth a go gl and tell us your temps after you do it

well, with a dual core my idle temps are ~30c and load is ~45c. not bad i guess, but it could always be better right? i bought some ram heatsinks to try the Big Typhoon mod that was in the guides.

so a higher cfm inlet would create more dust and such, right? that means everything is ok now?

when refering to case temps your CPU temps are not that critical.

Whats important is the temperature differential between ambient room temp and case temps.

Ideally you want the differential to be as small as possible indicating that the cooling is sufficient.

I have an Antec SLB as well and my temps are:

Ambient: 20-22*C
Case: 25-27*C

This shows a temp differential of only 5*c which imo is very good

And its vice versa on your final comment with respect to dust ingress.
I find a higher CFM fan on the rear give a couple of deg C difference than vice versa

personally mate, i have to tell you that neither positive pressure nor pressure is good for any casing unless it is built well to take advantage of the turbulence created inside the casing due to the difference. in anycase the term positive and negative pressure is an anomaly because if its positive pressure inside the casing then it means the net pressure inside the casing is higher than ambient pressure of 1 Atm. if its negative then it means its below that ambient pressure.

if it follows the above positive pressure definition then, dust and particles will not get into the system casing (think of Clean Rooms and ARPA filters) and it will be slightly cooler inside the casing due to air escaping out faster. if its negative pressure then u will have collection of dust and higher temps. this is in a nutshell but there are lots of compounding factors to this. in any case like i said there is no such existent phenomenon inside a computer casing. what u have is net positive and negative air flow which should be balanced so that you have sufficient Q, Heat transfer.
