fan/heatcore placement

[Saurk]

I have a d-tek heatcore and three 120mm fans in my case. Two 120mm are at the back, one in the front w/ the heatcore. The rear fans are installed in the case as exhaust. Front fan blows into the case through the heatcore. It would be really easy to turn it around so that the front fan sucks air through heatcore into the case. I'm not sure which is better.

right now I have it as:

<- rear case bezel <- rear fans (2) <- inside case <- heatcore <- fan <- front case bezel <-

"arrows" indicate direction of airflow. This was the way it was set up when I bought the case but I don't think it's very efficient. If the front fan is the only one drawing air into the case, (and with a lot of resistance from the heatcore), then I will have a low pressure situation in the case. Any suggestions for improvement?

Your case isn't air tight, won't be anywhere near a vacuum

Some people say that negative (low) pressure in your case is a good thing because of thermodynamics (Pressure increaces Temp decreases and vice versa), others say that doesn't matter, and tyr to get positive pressure in their case to keep dust out.

It's really up to you because from what i've read, either way it doesn't make too much of a difference.
Personally i'm trying to keep negative pressure in the case of the computer im building, cuz i'm a firm believer in the laws of physics.

Just my 2 pennies

why don't you add another 120mm fan on the heatercore and do a push/pull config?

Yes, I meant neg. pressure.

I don't think it makes much difference, but I'm primarily concerned about keeping the heatcore cool. Do people usually have the heatcore fan blow air through the heatcore, or, umm, suck air through it? (keep yer minds outta the gutter) :Q

That might be a good idea...

I was also thinking of making some kind of shroud for the heatcore. What have other people done that worked well?

most people have air being sucked through the heater core. Usually with a shrowd of some sort.

aside from making their own shroud from metal/tupperware/etc...you could get the one dtek makes specifically for your heatercore.
