[QUOTE="Anusha, post: 114939, member: 828"] I don't agree with you. Even if you have zero case fans, the case still sucks dust in. Why? Because the power supply unit's exhaust fan makes a vacuum effect and from the vents in the front and sides of the case, cool air comes in. Hell, even with only on exhaust fan running at 7V instead of 12V and the power supply unit's two fans, I still feel cool air being sucked in when I put my hand close to the vents. Dust comes in regardless of whether you have intake fans or not. And remember, dust is not dangerous as excessive heat. Heat should be given the priority. Besides, you can clean inside of your case every one month or three months. You can't do something like that about the heat. And remember, dust can't do much harm to the circuit boards because, the circuit routes are covered with a glossy coating and most boards have internal connections (as most of them have several layers). But one thing to remember is that you should not let dust deposit on heatsinks, because then, it will make it less and less efficient in dissipating the heat out. Not every casing is designed to make a good air circulation, especially the ones we find in Sri Lanka - the no-name brands or the unpopular brands. The pioneers in case design have good designs - yes. Anyway, you have to have a good cable management inside the case such that the cables - IDE cables more specifically - do not block the path of the air. Try to keep them directly [B]out[/B] of the air flow of the intake fans. Opening up the case might help in the short run, but I also don't recommend that. If you have to keep your case open to make it work, it means something is seriously wrong with your system. Address that issue properly. [/QUOTE]
