Determining loudest components?

post #1 of 13
Thread Starter 
Hi, all. Was just perusing OCN (haven't been on in a while) when I found this sub-forum. As it were, I'm in need of decibel-lowering advise with my current rig.

Unfortunately, I have zero knowledge on the subject of quieting desktop components. These are the only three things I have, at the moment:

1) How do I determine which components are causing the most noise?

2) I'm using a stock, 120mm intake fan (light-up one died recently) and my exhaust fan has a short in it. In essence, both need replacing and I figured I should ask for advice before blindly purchasing new ones.

3) I also have a 180mm side exhaust fan that I'm hesitant to replace and I just installed a Zalman 9900MAX, my first aftermarket/non-stock CPU cooler. I wasn't sure how much I was going to overclock my FX-8320 (still don't, actually), but I decided to attach the included RC7P resistor cable, just in case.

So where do I go from here? You guys aren't all going to recommend Noctua fans, are you? I'd love to buy them, but $20 fans aren't in my budget, as of now redface.gif

I skimped on the details, but if you need to know anything else just let me know (specs are in my sig). Thanks, guys. Good to be back!

Go on newegg and compare fans. I myself like GELID fans, they were like $10 each when I bought them, are very quiet, and move a good amount of air.

To determine your loudest component, just turn off everyone and test each individual fan.

If you are hesitant to drop $20 each on fans, I see where you are coming from, but fans are so essential and will last you a while.

If you're trying to save money you can opt for stuff like Nexus (yate Loon D12SL-12) fans but you can't mount them horizontally or you will need to do maintenance (oiling). They're sleeve bearing.

A really low cost thing to do is to clean your GPU's heatsink: it's quite likely it's clogged with dust if you lack filters on your case

Yea, with the static/sound issues I'm having it looks like I'll have to buy a speaker system and now a couple of new fans at the same time so money's a bit tight. Granted, leaving stereo audio behind for 2.1 or surround sound mixed with a quieter case has me itching to research all that I can so I'm leaving no stone unturned.

My problem with dropping $20 on a single fan is that, ideally, I'd like to have them all running at 100%. I don't know enough about internal temperatures to have my BIOS determine fan speeds for me. That being said, a $20 fan dying on me after a short while doesn't sound very pleasant. Then again, that $9 exhaust fan did last me 2.5 years. Perhaps it's just because I don't have any experience dealing with such expensive cooling components.

I recently installed some new components and gave my case and hardware a good cleaning with compressed air (as I always do). Would you still recommend cleaning out the GPU's heatsink? Not sure if it's worth it considering my O.C.D. makes me a thorough cleaner as is, lol. Unless you mean taking off the plastic guard and physically wiping any residue off of the heatsink. If so, I'd be willing to try that.

Thanks a ton for the answers, [Willanhanyard] and [AlphaC]. I'll look into the links and fans you guys suggested.

If you buy a $20 fan it'd likely have a a good 5 year warranty.

As for cleaning off the heatsink I'd just take it out of the PC and use a Datavac or compressed air to blow the dust out. The only reason you'd need to take the shroud off is if it's seriously thick dust that's stuck.

Hm... Well, I guess it's entirely dependent on how much a couple of fans and a speaker system come out to be. Like I said, I'm open to all options at this point. I can always scale something back if I find the total price to be a little out of my range.

And hot damn, that thing is exactly what I was looking for! I was getting tired of buying compressed air and even a small air compressor seemed like complete overkill, but that thing looks perfect. Another thumb.gif for you, [AlphaC].

Noctua fans are $30 each here in Australia biggrin.gif
If your looking for silent fans, check out Corsair's AF and SP Quiet edition series. AF stands for air flow, so they make great exhaust and good intake fans. SP is for static pressure, they're good for pushing air through a heat sink, HDD cage or pulling air through a restrictive filter.
They also come in twin packs, so you can save a bit of money by going that route.

1) Clean out all fans and heatsinks.

2) Determine loudest component. Start by unhooking the data cable to your C: drive so that your system doesn't boot into Windows. That way you can turn your rig on/off at any time without waiting for Windows.

3) Replace the dying fans with new ones. For decent cheap fans, look for Yate Loon as AlphaC suggested. Note that there are "fake" ones, which I believe is where most of the problems come from with running them horizontal. See this thread.

Note that there are a few universal truths in fans. With all else being equal:
Higher RPM = higher noise
Higher airflow = higher noise
Higher RPM = higher airflow

Now, fan bearing design and especially fan blade design can have an effect on this noise/airflow/RPM link. However, they are still linked. There is no magic way to get around this. A good fan can give a bit more airflow for the noise (alternately, same airflow for less noise) but it is within a range.

If you want to run fans at max RPM all the time yet be quiet, then you need to buy fans that have lower max RPM, which will give you lower airflow.

You also need to pay attention to the static pressure of the fan. Fans with higher static pressure tend to be better on radiators/heatsinks. They'll work as case fans, but you'll get less airflow. Low static pressure fans give you more airflow for case fans, but will have difficulty pushing air through fins of a cooler.

Thanks for all of the great answers, guys. Before I continue any further, though, I should ask a rather important question. My three case fans are only plugged into my PSU. That means

a) they always run at full speed and
b) there's no way to monitor them, correct?

If so, then I guess I can only really follow [Zap]'s advice and buy fans with lower max RPMs. I'm not sure how that will affect a gaming rig, though (unfortunately, I haven't taken any temperature readings yet). I could try to put another fan in front of (behind?) my two HDDs in a push/pull setup to help the front intake fan since air flow would be reduced due to lower RPMs. It also has to suck air through both a mesh filter and a plastic, honeycomb design on the front of the case.

Can't really do anything else until I start unplugging stuff and listen to each, individual fan to see what's loudest. Will post the results when I do.

From your manual:

http://download.gigabyte.us/FileList/Manual/mb_manual_ga-990xa-ud3_e.pdf

You could use a fan splitter to use motherboard control off SYS_FAN1 or CPU_FAN.

You can use Speedfan if easytune isn't to your liking (it's not that great)
