Motherboard / AGP compatibility question

[Peter]

intel didn't add intake fan to anything, they just switched the board 90 degrees. the cpu is at the front with an intake fan

And that sentence makes sense because?

You better shut up now before EVERYONE's laughing.

BTX turns the board 180 degrees, and adds an intake fan to direct fresh cold air to the hottest component. That's how cooling works best. Yes there is an exhaust fan in the PSU too - but that one has been there in the ATX 2.0 standard as well. Btw, the original ATX 1.0 standard had nothing but an INTAKE fan in the PSU.

jeez, my bad 180. the board is turned 180 cpu at front with intake fan. you still didn't asnwer my question, do you run all your fans intake? why not run all fans as intake if its so grand?? so that it blows out all the air from the cracks and crevices?? so that you would never have to clean out the inside of case?? and why did they change it to exhaust in psu?? why not leave that alone at intake???

Just one more food for thought: You cannot exhaust more air than goes into the box. No matter how many exhaust fans you add. And the bigger the suction force inside the case, the more air will be inhaled through unwanted spots, rather than through the intended path of airflow.

I guess Intel are just as clueless as we are for adding an INTAKE fan in their new BTX system specification ...

that is the small price for having more exhaust than intake. thats why for proper maintence, you want all your slots to be covered to minimize this inhaling of air to just small cracks. cover the case, cover your front and back panels slots. you make it sound like the inside of pc will be covered in 1 inch of dust in a matter of weeks.

intel didn't add intake fan to anything, they just switched the board 90 degrees. the cpu is at the front with an intake fan, but there is still the back of the case with space for exhaust fans correct?? just like atx except now the cpu is closer to intake, instead of at exhaust. and the psu i understand will still exhaust hot air out, rather than suck cold air in right??

i have a question, do you run your all your case fans, including the back ones as intake??

Perhaps you should stop inhaling or at least stop posting.

No, silly, just as much exhaust as there is intake. As I originally wrote on page one of this originally useful thread. Just go back and read.

Just to let you know: Industrial rack cases - as used in aviation, military, telecomms, you name it - indeed have nothing but intake fans, using a straight airpath across the CPU and the rest of the components, and back out the other side. Without any exhaust fans there. This is exactly the way Intel designed their new BTX approach - including the fact that the only thing with an exhaust fan in those systems is the power supply unit.

This is much more effective than having the fans run the exhaust direction, for the simple reason is that on the pressure side of a fan, you get a directed airflow to where you want it. On the suction side, you don't.

Simple example: Try blowing out a candle. Then try sucking it out.

Why'd the ATX specification reverse the airflow from 1.0 to 2.0? Because CPUs got stronger and hotter, making the idea of having the PSU fan blow cool air onto the processor insufficient. CPUs then got their own cooler, in brand machines often even got their own air INTAKE from the back of the case. At the same time, PSUs started to run warmer, which led to reversal of its fan so the now warm air from inside the PSU doesn't go inside the case.

That's all blatantly obvious. Except for you, it seems. Before you post your next nobel prize winning article, go read up about the topic. Intel's web site still has all the documents online.

ok, how bout this. ATX..... intake air, it needs to travel longer distance to the hottest part in case (cpu), and it hits all these cables blocking the pathway, while exhaust fan is much closer to cpu. since cpu is hottest part, and the hottest part gives off hotter air then anywhere in case, shouldn't the exhaust in back be better than an intake which is furthest from the cpu??? this is for ATX setup.

therefore 1 exhaust in back, is better than 1 intake in front, .. therefore 2 exhaust/1intake , is better than 1 exhaust/2 intake.

fans closer to the cpu is better than fans furthest from the cpu. yes/no?

 

[Peter]

It doesn't matter where the fans are. It's about where the airflow travels, and about how much throughput there is.
All further explanation is lost until you catch up with the basic physical concepts of cooling.

Peter

Your airflow and fan suggestion makes good sense.

Thanks

I have to agree with Peter,go for brands like Antec,Enermax,Sparkle,Enhance etc and you`ll be on the right track.

Would this PSU "Sparkle Power "Power Q" 350W" be sufficient for most budget mobo's? Mainly the ECS K7S5A PRO?

 

[Peter]

No Sparkle over here, so I don't have personal experience. But the general opinion on them is good.
