Question by ChrisW: Computer Fans? 3 quick questions : 1.Is it better to have 2 80mm fans or 1 120m fan at the front?, my case supports both 2. Is there any good way to place fans in your case, e.g say setting fans up so the front ones inhale fresh air and the back ones extract the warm air. 3. What is a good dB level, is there a common dB level that is use in factory built ones, e.g ones you buy in a store. I was looking at some 25dB stuff, u dont really want to go highter than that but was wondering what is a good level (I dont want to spend a fortune on ultra-silent ones or watercooling though. Best answer for Computer Fans?:

Answer by interlude
1. It all depends on the fan, but my personal preference is to get a bigger fan. Bigger fan usually has lower noise. I hate noisy computers. Having two 80mm fans may generate more air flow, however, depending on what kind of fans they are. 2. correct. you generally want the flow of air to go from front to back. inhale from the front - preferably with a filter - and exhale to the back. side panel can go either way, although I prefer to inhale from the side as well. 3. dB level is a tricky one. Most fans have some sort of db rating, but some of them are completely inaccurate and useless for the general population. Generally, the lower the better. WIth a db rating of 20, you can barely hear it. 30 sounds like a hum, 40 starts to sound like a noisy fan, 50 sounds like a vaccuum cleaner. I prefer around 20-25 on my computer parts. Also, it sounds like you're going for a quiet computer. Try getting a better case that has sound dampening side panels or get the sound dampening material and glue it to your case yourself. As with cases, if you use one with the side view, you're going to sacrifice noise level for a light show. Enjoy modifying/building your computer

Cooling fans for greater CPU performance Cooling fans for greater CPU performance So you've reformatted your hard drive, you've downloaded some anti-virus software and your computer checks out clean, you've shut down all the peripheral programs that you don't really need to be running, you've added a ton of RAM, you've cleaned your computer out, so to speak, and it's still running along at a snail's crawl. You're getting single digit frames per second for media and gaming, you freeze up whenever you open more than a couple windows at a time, and you have no idea what the heck is going on.

Oftentimes, slow computer performance has nothing to do with the software running on your PC or Mac, it has nothing to do with how much RAM you have or viruses or anything like that. Sometimes it's a much more practical issue: over heating.

All computers are susceptible to overheating. Everything from the supercomputers used in the Pentagon to that solar powered pocket calculator you had in high school. This is why most desktop computers have cooling fans built in. In fact, even most video game consoles have a cooling fan built in in this day and age, it's just that important.

The problem is that cooling fans, like every other part of your computer, don't last forever. CPU cooling fans will eventually wear down. After all, it's just an electric motor, and like any electric motor, it needs replacing every now and then.

Checking Your Fan

With some PC towers, you can look at the fan in action. If this is the case, then it should be easy to see if it needs replacing. Is it spinning when your computer's on? If not, then it certainly needs replacing. If you can't see your fan through your tower's casing, you'll want to crack it open and, carefully, turn it on. See if it's spinning, and if not, turn it off and remove the fan.

Check Your Specs

Check the specs on your fan. The majority of returns on computer parts, from hard drives to CPU cooling fans, are simply the wrong size. When you return a part and have it replaced, the shipping is all on your dime, so make sure that you're checking your specs before wasting your time.

When you have the specs, just get online and buy a replacement, simple as that. You plug it in and you're good to go.

"My Computer Didn't Come With a Fan!"

For other computers, you might not need to replace a fan, you might just need to buy one in the first place. Laptops, for instance, don't usually have room for a cooling fan, which is why you'll find those coolers that go underneath the laptop and blow cool air into it. A little cumbersome for taking your laptop around town, maybe, but for at home use, these coolers are a life saver, especially if you work on your computer and need it to be running for hours on end every day.

Clearly there are other issues to worry about, too. You do need to be aware of viruses, you do need to be aware of RAM and processing power if you want to use your computer for gaming or media, but cooling fans are one of the more important, and most neglected, factors that weigh into a computer's performance, especially as your PC gets older.
