Reversed Cooling

post #1 of 5
Thread Starter 
I Just Had This Idea When I was drinking some soda and finished it I was sucking on the hole and I noticed it got alittle colder so I poked a hole in the side and sucked again and it got more cold.

so I thought to myself why not do it with a computer, yes I know a computer and a soda can are two very differnt things but who knows.

since I can't do it with my computer ( my dad wont let me lol) can you guys do it.

Just Revurse the fans and tell me what happends plz

if no one thought of this I declare this idea MINE! (tech. it is my idea cause I just thought of it lol )

ok well thnx.

yep people have thought of it lol. are you just considering changing the fans so they are both pulling out air? and sucking air off the heatsink. if so then this doesn't help, better to have cool air pumping inwards towards the computer. and then out through an exaust fan.

You don't want to do the intake/exhause (AKA flipping fnas) experiment with the case fans. You want to have the air intake/exhause balanced. Thus, 2 intake/2 exhause would be ideal rather than 2 intake/3 exhaust, etc.

Now, I flipped over the heatsink fan on my XP-90. Guess what? The temp. dropped ~5*C. Thus, I was able to push my CPU a little further to 3.833 Ghz.

I found, in my situation, that sucking the hot air from the CPU is better than blowing the air into the CPU. If I were to take off the side panel on the motherboard side of the case, the temperature would drop even more.

Conclusion: It all differs depending on the environment you're in, the case architecture, etc.

lol. i have a peice of laminated card between my CPU fan and the side of my case. The side of the case has lots of holes for ventilation, so the CPu sucks in fresh air from outside the case. VERY simple but VERY effective. If i remove the peice of card it get 5c+ hotter... which pushes me VERY close to 70C @ load, which = BOOM.

PS. Me no like CPU go BOOM
