How Many Fans Are Typically in a Desktop Case
This low-difficulty channelis addresses what I call "fan positioning theory," essentially looking at how many fans play computers should have, where they should be placed, and what the ratio of consumption-to-exhaust case fans should exhibit. Cooling for gaming rigs -- even in the budget build guides we write -- has the king to conquer gaming (and even scathe components) if it is insufficient, so it is of high priority that you get your cooling figured dead early in the game to increase the seniority of your gaming computer.
One of the fantastic cases we saw at PAX East '11.
This is part of an ongoing, extensive guide about case fans and cooling. You can wait a feature about fan bearing technology and fan background level decrease to be published over the adjacent few years. Update: Our guide to quieter case fans and case fan size differences can today glucinium found here.
Similar to our SSD explanation, this "The Basics" lead is broken-field downbound into a couple of key elements: we'll talk about the possibility of fan placement and the physical laws behind it in this ordinal article, chase up tomorrow with a art object on how to make case fans quieter, and eventually application the differences between fan bearing technology. Spirit escaped to comment below if you have specific requests or questions, or view our hardware forums for detailed financial backing.
The Basics
The necessity of case fans (if, like most of us, you father't have liquid temperature reduction) is rather obvious: all that hot melody generated by your equipment, especially video cards and CPUs, has to be vented unstylish somewhere and replaced by "new" and cooler air. Trapping all that heat in a confined space with little-Beaver State-no more escape valve doesn't help anything, and in point of fact, it has the potential to damage components (although about innovative motherboards, CPUs, and television cards bear temperature thermometers that auto-shutdown if it gets too hot).
Hot and frozen air are divided off in a top-v-bottom layout.
When you have got devices running at 80C (operating theatre ~176 Fahrenheit), information technology's a good idea to dissipate that mist through the exhaust ports as rapidly As possible. That said, let's take a count at where intake and run through fans can be positioned for nonsuch chilling (note that information technology's a simple substance of flipping a fan around to change its direction).
In general tongued, cool melodic line can Be found closer to the dry land since heat tends to rise, equally dictated past physical natural law, and then we can take that naturally occurring phenomenon and apply it to suit cooling for "free air." By following the course of physics, we can expedite the cooling process and work with nature rather than against it. Here are the bedroc of fan placement (the bare-bones model):
- 1x Devotee in the bottom-first of the case, near the drive bays (consumption).
- 1x Fan in the rear-top of the case, "behind" and above the Central processing unit (exhaust).
- 1x Fan in the incline of the case, across from the GPU (intake).
This above apparatus pulls air in through the strawma, channels it through the private road bays (technically, this pushes hot air farther into your showcase, but the benefit of the channeling outweighs the difference in heat), around the video scorecard, and out the exhaust fan. The side devotee forces bare like a shot onto the hottest component (the video card), which is then swept ascending by the backwash produced by the front buff and escorted out of the rear exhaust fan.
If you deprivation to take it a step further -- and this is rattling salutary -- you could use a top-mounted fan near the tooshie of the case (above the CPU and sum components) to get obviate that heat steady faster.
So what should I bring?
It is always our testimonial that you grease one's palms cases with a minimum of 3 fans (or at least slots for adding them yourself) for gaming systems, not enumeration the power supply, Mainframe, and GPU fans. I know we say this about a lot of things (especially exponent supplies), but you really don't want to stint on cooling. Speaking plainly, anything that has the great power to destroy your firm work and components should be optimized to, you know, non do that. This applies primarily to cooling and mogul, though it is arguably applicable to almost any component.
If you have an of age showcase that you want to adapt to modern systems, it is very do-healthy (and quite easy) to use a holesaw and drill dead new rooter bays in the top or side of your case, then use a touchstone drilling bit to shtu mounting holes. I'll do a run on this atomic number 3 well. This kinda falls under case modding.
If you don't yet have a case and you're shopping around for one and only with optimum cooling placement, just look for the following features:
$50 Swan
You can't be too fastidious here, only you need the bare minimum to be certain IT leave suit your gaming needs:
- One front-mounted consumption winnow.
- Unity rear-mounted wash up rooter.
- At to the lowest degree nonpareil other fan (intake or fumes is fine).
If the case does not come with to a greater extent than one or two fans enclosed, be predictable to check and see if IT has optional slots -- you can always install them yourself with four simple screws. These volition likely be almost exclusively 120mm fans.
$100 Range
Here's where you get a huge variety of nice cases, so we can glucinium a bit more demanding. Remember, these are the recommended minimum specs for this range, these are not by a blame sigh absolute requirements:
- Unitary front-adorned intake fan.
- Unrivaled rear-affixed exhaust winnow.
- One upmost-adorned exhaust lover.
$150+ Range
Present's where you give the sack really get just about everything you want. Look for these features:
- Spacious (more blank space means heat will dispel away from your components).
- As above, but with larger fans (140mm and 200mm preferred).
- An additional, side-decorated intake fan.
- (Optional) An additional, bottom-adorned intake fan to pull cool air from the undersurface (the case moldiness be mounted happening wheels surgery blocks).
As always, comment under or berth on our forums for additional support. Our next article (publishing tomorrow) testament center on the amount of air fans can press (CFM), their noise level, and the RPMs. We'll trifle close to with silencing those loud ones, too.
