A small correction regarding the laws of thermodynamics and convection. - Page 8

post #71 of 108
Doesn't matter how many times it's explained or how much proof is posted, people will still argue with you. I, for one, am happy to see another post supporting the argument I've made with (too) many people. Provide your radiators with the coolest air possible (i.e. always intake), create good positive pressure, have at least one decent exhaust (preferably near VRM to encourage passive cooling), and as long as you haven't built in a completely airtight case, the likelihood of increasing case temps more than a negligible amount is extremely low. Using all rad mount points as intake also allows me to employ quality filters and so far, it's helped my rig stay very clean. Anyone who is that concerned with 1-3°C in case temps should probably be running blocks on everything and completely external rads.

Another newbie necro-posting 3 year old threads babbling on about radiators in front, top and bottom intakes on the Air Cooling forum and claiming one exhaust vent can flow all the air the 5-8x 120 / 140mm radiator fans are trying to push into the case.
A case can only flow the amount of air of the smaller of the 2, intake or exhaust.

My bad. I was led to it by a poster on a current thread and didn't confirm date or original post location. So I apologize for that. Definitely not apologetic for supporting the dissemination of corrective information. If you would, kindly link conclusive evidence to the contrary. It would be greatly appreciated! All I have been able to find so far are tests debunking the "rads must be exhaust" myths. My next build and I thank you!

Ideally we want about the same amount of airflow potential into as case as there is exhaust. A little more intake potential is nice with filtered intakes as it keep dust out.

If you have everything in system on a cooling loop is is okay to use radiators as intakes But if not it becomes a balancing act of supplying everything cool enough air for proper cooling.

You might find "Ways to Better Cooling" linked in my sig interesting. 1st post is index, click on topics of interest to see them.

Looking forward to reading. Thanks, doyll!

"Necro" is only applicable when the subject is something that loses all relevance through the passage of time.

This topic's subject clearly does not. It is also not justifiable to attack someone ("babbling") based on how long they've been posting here. If Stephen Hawking makes his first post then his being a "newbie" is hardly the most important factor to consider when examining his posts.

As for the opening post... I would definitely never do this with my setup because the VRM cooling on my board is the biggest limitation for my overclock and the northbridge also already has enough heat issues. It makes more sense to just take the radiator outside of the case instead of pumping hot air into it.

I also feel that if the topic is still open-ended, necro posting doesn't really apply but I am new to the forum and don't want to be disrespectful to anyone. I did mention rads in an air cooling thread, though.

Anyway, I have to agree with you. Clearly, we can circumvent the question of intake vs exhaust if we there is a radiator chamber separate from the motherboard compartment or if the radiator is moved outside of the box entirely. I promised myself I would do that on my next build but I'm rebuilding a 650D on a budget and if you've seen one, you know how limited space is. I need all the performance I can get out of the limited rad space I have. smile.gif

You are misinterpreting my post
"Newbie" because mmurray is a newbie to OCN. That is nothing wrong or negative with being new to a forum.
"Necro" for reviving after 3 years.
necropost = to post in a thread that has been "dead", by being inactive for a relatively long period. "Babbling" is what mmurray did with his all radiator intake scenario with extremely unbalanced intake to exhaust vent airflow areas. Assuming Stephen Hawking is a great mind (many academics don't think he is), he would not use 5-8x intakes to 1x exhaust.

Not to mention following discussing is pretty much the same thing you are saying about cooling. I'm assuming you do not have a full coverage block on your motherboard.

Nope.
