How to Silence Your Noisy Computer (and Keep It Cool as a Cucumber)

By Whitson Gordon

How to Silence Your Noisy Computer (and Keep It Cool as a Cucumber)So you've got a kickass computer, but the summer heat means a warmer office, which means a hotter computer, which explains why your computer's been impersonating a jet engine lately. If your computer's generating a bit too much heat and noise, here's how to give its cooling system an overhaul for cool, silent operation.

Whether you have an old desktop or a brand-new home-built machine, you can reduce the noise in a number of ways. What you'll need depends on your case, your hardware, and your own personal preferences, so we'll go through each tweak separately to help you put together the perfect cooling system.

Understanding Heat

Like most electronic devices, your computer heats up when it's in use. Your processor, graphics card, motherboard, and power supply all get hotter the harder they work. Without some sort of cooling system, they'd quickly overheat and fry themselves. So, we traditionally use large metal heatsinks to direct the heat away from those components, and then blow that hot air out of your computer with fans. The problem is, fans can be noisy, and the fans that come with your computer are often cheap, loud, and ineffective.

So, the first step in silencing your computer is improving your cooling. The more efficient your cooling system, the fewer fans you'll need running at full blast. We're going to take a look at hardware that can make your cooling more efficient, fans that run a little bit quieter, and a way to control it all so you can keep it quiet when your computer isn't working hard.

Step Zero: Clean Your Computer

Price: $5

Click to view Before you do anything else, make sure your computer is clean and dust-free. If you've had it for more than a year, chances are it's built up some dust on the fans and heatsinks, which will make it run hotter (and thus louder), so grab a $5 can of compressed air and clean that sucker out. When you're done, you may find that it's gotten a little quieter already.

Step One: Get a New Heatsink (or a Water Cooler)

Price: $30-70 for a heatsink, $40-400 for water cooling

How to Silence Your Noisy Computer (and Keep It Cool as a Cucumber)Some of the loudest components in your computer are the CPU cooler and the fan on your graphics card. Often, the ones that come with your computer are super loud, and they aren't all that great at cooling in the first place. So, one of the best things you can do to keep noise and temperatures down is to buy an aftermarket cooler. You have two choices: heatsinks and water coolers.

Heatsinks are large, metal constructs that conduct heat away from your hardware and then blow it through a fan to keep everything running cool. Aftermarket heatsinks can be quite inexpensive, costing only $30 for a simple CPU cooler and $43 for a smaller graphics card cooler. If your CPU or GPU fan is very loud, adding a higher quality heatsink with a quiet fan can keep everything much quieter (not to mention much cooler). Photo by Robert Freiberger.

How to Silence Your Noisy Computer (and Keep It Cool as a Cucumber)If you want to get a little more extreme, you can try water cooling your hardware, which runs water over the components and cools them through a radiator. The radiator still requires fans, but is so effective at cooling that you can often use fewer fans in your case, and run them at lower speeds. We've talked about this a bit before, so I won't get into it too much here, but it can be a great alternative to air cooling if you're looking for something quiet. You can use an inexpensive all-in-one cooler like the Corsair Hydro Series, or put together a loop yourself. A homebrew loop will require a lot of maintenance and cost a lot of money (at least $200 or $300), but it will be very effective and very quiet. For more info on setting up a homebrew loop, I recommend chekcing out NCIX Tech Tips' ultimate water cooling guide. Photo by Dave Linger.

Step Two: Upgrade Your Fans

Price: $10-$25 per fan

How many fans you choose depends on your case, so you need to take a look at what you have before you go buying fans. Let's take a typical mid tower computer case, for example, with two fan slots in the front, and one in the back. We want the air to follow one path through the system, from front to back. That means we'll use our front fans as intakes, and our back fan as exhaust. Air comes in through the front, blows over your hard drives, then to the rest of your hardware and out through the back. Having the back fan at the top is especially handy since hot air rises, so it will blow out hot air first. Your graphics card and power supply will cool themselves on their own, but it's nice to have some of that cool air flowing over them as well—if you have a side intake fan or bottom intake fan, that can help.

Generally, we recommend setting up your fans for positive air pressure—that is, that you have more fans intaking air than you do exhausing them. This not only cools your graphics card better, but coupled with a few dust filters on your intake fans, it can keep a lot of dust out of your case, since you won't have any air creeping in through the nooks and crannies of your machine:

That way, the only air that comes in is air through your filtered intake fans, which keep the majority of dust out. For more information, check out this article on Silverstone's web site.

Your case may have more than three fan slots, so you'll obviously need to adjust this plan based on how many fans your case can take and how many you actually want to use (remember: more fans = more noise, but also better cooling). Once you've figured out how many fans you want, you'll need to research what kind of fans you want. As you browse different products online, you'll want to look at a few things:

How to Silence Your Noisy Computer (and Keep It Cool as a Cucumber)

  • Air Flow: This rating, usually expressed in cubic feet per minute (CFM), is how much air that fan will blow—essentially, how good it is at cooling. The higher the CFM rating, the better it's going to cool down your hardware.
  • Noise Level: Expressed in dBA, this tells you how loud the fan will be at its maximum speed. You'll find fans with 20 dBA of noise or less are very quiet, while fans with 25 or 30 dBA are a bit louder.
  • Size: Fans come in multiple sizes, and each fan slot on your case or heatsink will usually only fit one size fan. So make sure when you're shopping that the size of the fan matches where you're going to put it in your case.

If you know what model fans are currently in your case, look them up online and see what their air flow and noise level ratings are—that way you'll know what you need to look for if you want something quieter or with better cooling.

Lastly, if your case doesn't come with dust filters, grab a few filters for each of your intake fans. This will help you keep dust out of your case, which can make your computer run hot and your fans run loud.

Step Three: Invest in a Fan Controller

Price: $20-$60

How to Silence Your Noisy Computer (and Keep It Cool as a Cucumber)No matter how you arrange your setup, you'll want some way to control your fans. That way, they'll be silent when your computer is idle, and louder when you need the cooling performance (during intensive processes like gaming or video conversion). If you only have a couple of fans, you may be able to control them automatically, but if you have more than a few fans—or if you just want a bit more control over the noise levels—I can't recommend a fan controller enough. It fits in one of your computer's drive bays and lets you adjust fan speed with physical knobs. Some will even monitor the temperature of your hardware for you, which is pretty handy.

Most fan controllers can take up to four fans, but with an adapter like this one, you can control multiple fans with one knob. If your fan controller has a screen that measures RPM, you may need to cut one of the yellow cables to get an accurate reading (since having two fans sending fan speed info can confuse most controllers). Fan controllers are also harder to find on sites like Newegg, so I suggest you look around for reviews on YouTube and other sites before you buy—you're likely to find a lot more than you will at any one computer store. Also remember that if your fan controller measures temperatures, it won't be reliable for something like the CPU—you'll need an app like Core Temp to measure the true temperature of your CPU.

Other Noise-Dampening Products You Might Want to Try

As you're buying the main hardware for your case, you may also want to check out some of these accessories that are designed to keep your case quiet:

  • Silicone Fan Fasteners: Your fans can often vibrate between your case and their housing, which causes extra noise. You can solve this problem in most fan mounts by using rubber or silicone fasteners instead of metal screws. It'll keep them in tight, but dampen all of the vibration. Most higher end fans come with their own set, but you can also buy a big pack separately for about $5.
  • Hard Drive Enclosures: While replacing your hard drive with an SSD will get rid of that annoying hard drive whine, it isn't practical for everyone, so you may want a way to keep that hard drive quiet. You can try an internal enclosure like the SilenX Luxurae or the Smart Drive, but those are expensive enough that you'd actually be better off just getting a new hard drive designed for silence. It only costs a bit more and you'll get much better results.
  • Acoustic Foam: Some silence enthusaists recommend an acoustic foam like AcoustiPack insulation, which you can apply to the insides of your case to keep the noise level down. I've never found this necessary myself, and you'd have to be very careful not to restrict the airflow inside your case, but if you really want complete silence, it may help.
  • Dust Filters: I mentioned this once above, but get dust filters for all your intake fans. If you have positive air pressure in your case, then the only air coming in will be from your intake fans, and if they're filtered, then you'll have very little dust entering your case. The less dust you have, the less maintenance you'll have to do down the road, and your PC will stay quieter for longer.

The last piece of advice I can give is to start off with quality hardware. If you buy a cheap hard drive or a cheap power supply, you're going to end up with something that's loud. It's just the way of things. The next time you go to upgrade computer—whether it's all at once or on a part-by-part basis over time—take into account cooling and noise. Read reviews, look at its noise specifications (if it has any), and remember that you get what you pay for. You may spend a little more upfront for something quiet, but it's likely going to be higher quality and make you happier, not to mention maybe last a little longer.

Playing A Vampire In Skyrim: Dawnguard

Playing A Vampire In Skyrim: Dawnguard

By Jason Schreier

Playing A Vampire In Skyrim: DawnguardCrossbows, mysterious pale women, and a castle packed with nasty vampires: although the first few hours of Skyrim's first downloadable content start off a little slow, they've got some awesome things to offer—and they hint at even more to come.

Dawnguard, the expansion pack-sized DLC that developer Bethesda releases today for Xbox 360 (and later for PC and PlayStation 3), is good at slowly but surely building your excitement. Since receiving a code late last night, I've spent about three or four hours (who needs sleep?) exploring and hacking through Dawnguard's chunk of the world. And I'm psyched to see what will happen next.

While playing, I jotted down some notes about the experience. For your reading pleasure, here they are.

(Spoilers for the first 2-3 hours of Dawnguard follow)

  • The coolest thing you can do in this DLC, in my experience so far, is turn into a vampire. You get this ability by visiting a castle full of vampires, listening to the king's generous offer to give you his blood, and saying yes. (He threatens to destroy you if you don't say yes.)
  • As a vampire, you have a handful of special abilities. From the main menu you can use Vampire's Servant, which reanimates a corpse to fight by your side for 60 seconds, Vampire's Sight, which improves your night vision, and Vampire Lord, which zooms you out into third-person mode and morphs your character into a vicious beast.
  • As a Vampire Lord—which is where all your real powers come into play—you can't use regular equipment. Your blood boils when you enter sunlight. You can drain life and even transform into a swarm of bats (which is sort of like a makeshift teleportation skill.)
  • Turning into a vampire limits your inventory options until you revert back to human form.
  • Turning into a vampire will purge the werewolf blood from your system.
  • Turning into a vampire is really fucking cool.
  • But how do you get that ability? Let's take it from the top. When I log into Dawnguard for the first time—which is really just logging into Skyrim with the DLC downloaded and installed—I load up my old character, who had been hanging out in the city Whiterun. Immediately I'm accosted by a bunch of vampire thralls. Once I defeat them, a man named Durak comes up to me and orders me to go check out Fort Dawnguard, in the way southeast corner of the map.
  • See, Fort Dawnguard is where a group called the Dawnguard lives. They fight vampires. Like Buffy, but with Viking accents.
  • If you start random conversations with the guards, they talk about the new vampire menace and how they wish it would go away.
  • Eager to see a bunch of cool new shit, I make my way to the new area, which is southeast of Riften. I trek through an area called Dayspring Canyon and pass Stendarr's Beacon.

Playing A Vampire In Skyrim: Dawnguard
  • Fort Dawnguard is huge. It looks lovely and romantic in the snow.
  • Outside Fort Dawnguard, I meet a man named Agmaer. He's a little runt. He says he wants to join the Dawnguard, but he's scared because he's never done anything like this before. I vow that when I become a vampire and betray the Dawnguard, he'll be my first victim.
  • I see Durak training with a crossbow. We chat and he says it's the Dawnguard's specialty. He gives me one. "Nothing better for putting down vampires."
  • Shooting the crossbow feels nice and twangy, just like you'd expect. But it seems to reload way too slowly to be practical in combat at all. Maybe my character—a level 27 mage/swordsman—is just not built for ranged combat.
  • When I enter Fort Dawnguard, I fall into the floor. Talk about a groundbreaking experience.
  • Leaving and re-entering the room fixes this issue. Soon I'm chatting with Isran, leader of the Dawnguard, who asks me to go investigate Dimhollow Crypt, where a bunch of vampires are hunting after something. My job is to find out what that is.
  • I teleport near Dimhollow Crypt and make my way over there.
  • Oh, fuck off Ice Wraith.
  • I'm too powerful for this DLC—or at least the first few hours of this DLC. Everything dies very, very quickly. Even Master Vampires collapse in two or three hits.
  • So the dungeon is fairly easy. I do get to meet a new enemy, the Gargoyle, which is essentially just a new skin to attack.
  • At the end of Dimhollow Crypt, I find a vampire woman named Serana. She's casually carrying an Elder Scroll on her back. She asks if I'll help her get home.
  • I take Serana to her home, the aforementioned vampire castle (located in the way northwest). It's called Castle Volkihar. Her father, the king, asks if I want to join the tribe.
  • I am now a vampire.

Playing A Vampire In Skyrim: Dawnguard
  • In order to gain new perks as a vampire—which has its own skill tree—you have to kill enemies using your Drain Life or biting abilities.
  • Some of the higher-end vampire perks include Supernatural Reflexes, which slows everything down, Night Cloak, which gives you a cloak of bats (!) that feed on enemies within range, and Summon Gargoyle, which does what it sounds like.
  • I don't know why anyone would ever choose not to be a vampire. Presumably if you denied the king's request, you'd go back and fight for the Dawnguard. But... why?
  • There's a feeding pit. You can go up to human thralls and suck out their blood. It's hot.
  • I'm introduced to some other members of vampire court, like the nasty Orthjolf and Vingalmo, two oddly named vamps who are apparently out to get one another.
  • What's interesting about the vampire castle—and what will hopefully make this a cool plotline—is that everyone is just a straight-up awful person. Which will make for some interesting stories. Hopefully it's as cool as the Dark Brotherhood.
  • It will take every ounce of restraint in my body to not go around every city in Skyrim, eating people and bat-swarming my way through crowds of dumb guards. Gotta finish the actual game so I can review it for all you lovely readers. You're welcome.

I'll have more on Dawnguard, including a full review, in the coming days.
