ok, using my extremely l337 drawing skills, i came up with this great diagram and was wondering which ones you guys reckon is a lot better for cooling my athlon xp.... red arrows is hot air out, blue is cold air in, green and red thing is cpu ie hot area, case is full tower, and all fans apart from the one behind the cpu are 120mm's.... thanx for the help....
I think the one on the left would work better as its taking the hot air away and up which is the way it would naturally go.
i agree, even though i dont care for top blowholes ....and the sucky-in hole on the bottom just SCREAMS dust on the mobo ...
I agree with chrix, the one on the left would work better because we all know heat rises and the top fan will suck out hot air. Hopefully cooling your case.
Well they both have air coming in the bottom and exhausting out the top. You could put a filter on a bottom blowhole to prevent dust problems. In my full tower a top blowhole wouldn't be very effective since the top is a good 10 inches above the mother board and PSU. So I would go with the one on the left
i would have to say go with the one on the left. The only problem is dust! put a filter on it and you should be good. Whats yuor case look like? post a pic of it
i would say right. the front intake give air over the hard drive, the side one blows air directly onto the mobo and feeds more cool air to the heatsink on the processor.
yes, but if his case is tall and all his heat is lowwer in his case, the air would be drawn out better with the exhaust closer to the hot air.
if he pumps cool air in the bottom, the heat is gonna go out the top, no matter how tall the case is ... simple fact is heat does rise. accelerate the heat rising with a top blowhole, even 30 cfm is gonna help out immensely.i put a measly little 60mm with a duct blowing right across the hdd onto the ram & processor, and a 92mm blowing in on the processor from the side, and i dont have a single heat related issue. now then again im runnin a 1000mhz celeron, not an xp2000+ or whatever, so laugh if you like, but my case blows cold air out the back, and im happy.
i got a 92mm fan on side of me case straight on processor and one at back close to my cathdoe, one on the front sucking air in from me hard drives(it switches on oif i open the drive bay door ) and another on my vicdeocard, with this setup my tbird 1.4gig runs at 35 degrese during quake 3 at 1280x1024 not talkin bout 3d studio max...it reaches 38 there
I agree...filters are a must. Man am I sick of blowing dust out of my hsf! Personally, I LOVE having a top blowhole, so long as you can turn it off/on when you want. One thing to watch out for, though. Measure VERY carefully! If you use a big boy, like a 120mm, it can get VERY cramped between your Power Supply and whatever's in your top 5 1/4" drive bay. Whenever I want to do anything with my power supply, I have to take my fan out first. Unless you want to just mount it on the outside of the case, but I've always thought that it looks sort of akward like that...
either way, i think that both plans will work efficiently. The one with the top exhaust will naturaly work better because heat rises, but im not sure if one or the other is directly better
i was definatly getting dust covers for all my intakes especially the bottom one....and all the fans will be controlled by a reobus....now one of the main problems is that i have set my alpha pal 8045 to suck rather then blow, which means it extracts heat of the heatsink, and this heat needs to go somewhere.....
that heat thats getting sucked off is going out the back, or, its rising some where and then exiting. you are doing the plan with the bottom fan right? do filters restric air flow?
it will definatly restrict airflow, but rather that then a case load of dust...well, the heat gets sucked of the cpu and then is hopefully gonna leave the system out the back via an 80mm fan, but i was thinkin of puttin a 120mm directly over it to help it along in extracting the air but im not sure wether that would be worth it...
do you have yuor case yet? im sure you do, what is it. Post a pic of it some where, might help with the process of determining. just remember that the heat will get out some how or the other with the exhaust
