Very nice build by the way, though i think the duct could be made of something neater than cardboard.. like Polycarbonate for example

No joke, its the price you pay for living in a nice peaceful place. I'm 200m from the beach, all around me is bush, nearest neighbour is about 1km away. There are Koloas around, a couple of wallabies, lots of kookaburras, thousands of cicadas and some water dragons.nici wrote:Is this some kind of seriously twisted and sick sarcastic joke?

The old TBird sits outside on the veranda (it heats up the house to much) which is why it has spiders in it.
My place in Sydney is pretty much bug free, only the occasional huntsman and funnel web spiders.
Northern Europe is to cold for most of the nasties so your just not used to it.

I remember a Discworld book, "The Last Continent", where the Death goes to his library and requests a list of every single dangerous animal in that land (a thinly disguised pardoy of Australia. Two seconds later, he was knocked down and buried in books. He got up and asked for a list of non-dangerous animals, and got a small piece of paper with a short list on one side. Parody or not, that kind of puts me off wanting to visit Australia.

haha, nah. deadly aussie things are SOOO over-rated. for example the red back spider; pretty much the only time your bitten is when you disturb them or their web. and what kind of idiot goes around playing with spider's webs? just asking for trouble. simple common sense is all you need to survive in australianici wrote:Is this some kind of seriously twisted and sick sarcastic joke?

i'm curious how big the effect of removing a fan-grill is. can anyone quantify this a bit? suppose you have a fan with grill in the back that produces 23dba; how much would removing the grill with tin-snips decrease the sound level?matva wrote: NICE! i like how you removed the psu grill... i think i may try that.
lol, and i think "overly fanatical" is funny coming from mike, but i guess thats the point. Actually, i think it helps quite a bit:
would it diminish to 22dba? 21dba? 20dba? 19dba?

It's impossible for anyone to give you a precise dB figure, as it depends on your case airflow, the shape of the grill, whether it is a stamped grill or brass wire, whether most of your fan noise is bearing noise or air turbulence, etc etc. What we can tell you is that these type of grills:
are less restrictive than these types of grills:
and the least restrictive is no grill at all. Getting rid of the fan grill will improve your cooling and noise performance; cutting out stamped grills on PSUs seems to have the greatest impact, IME.
well it definitely makes a difference, but whether that difference is noticable depends on a lot things... for example, the computer's overall noiselevel. The way i see it, it costs nothing to remove the cages or grills, so why not if they* serve you no purpose? Besides, it is fun, and makes the case look better (imo).

ok, i understand that an exact answer is not possible. that's why i used the words 'a bit'. but a range maybe? for instance: is it in the order of 3db or less than 1db?jaganath wrote:It's impossible for anyone to give you a precise dB figure, as it depends on your case airflow, the shape of the grill, whether it is a stamped grill or brass wire, whether most of your fan noise is bearing noise or air turbulence, etc etc. What we can tell you is that these type of grills:

There's a MikeC thread (possibly in the "Fans & Control" forum, it may even be a sticky) where he talks about the effects of various fan grills. Look around/search and it'll probably pop up.sanse wrote: i'm curious how big the effect of removing a fan-grill is. can anyone quantify this a bit? suppose you have a fan with grill in the back that produces 23dba; how much would removing the grill with tin-snips decrease the sound level?

Does it count if it makes a difference to your neighbor who receives TV by antenna, not cable? Removing the grill on a 120mm fan is almost as bad as running with the side cover off to cool the case - you'd be spraying EMI (electro-magnetic interference) all over the neighborhood.matva wrote:The way i see it, it costs nothing to remove the cages or grills, so why not if they* serve you no purpose?

We covered EMI on page 2; the difference between grill and no grill is minimal, especially to your neighbour who is likely more than 10-20m away.Does it count if it makes a difference to your neighbor who receives TV by antenna, not cable?

At the very low fan speeds most silence fanatics (ie, RH & me, for example ) use, the noise difference between a low restriction grill and no grill is not audible -- except maybe if you're 6" away, in which case some very slight turbulence difference might be possible to hear. Where the difference is greater is in overall airflow -- even a wire grill imposes a ~20% reduction in airflow. The exact degree of impedance depends partly on fan speed... & the grill, naturally. So depending on the rest of your system, temps could be affected. Probably by no more than say a couple degrees for the CPU, unless you have a truly minimal airflow case... in which case, it might be greater.
I find that very hard to believe. From a stamped grill like the one on the back of the P150 i.e. perhaps, but from a wire grill? Really??? I'd accept a ~5% reduction without proof, but 20%!? I'm sceptic Born that way. SorryMikeC wrote:Where the difference is greater is in overall airflow -- even a wire grill imposes a ~20% reduction in airflow.

I would wonder if the "PSU test" procedure actually really stressed the PSU - if you wanted to really stress a PSU, attach as many hard drives as you can find to the 4-pin molex connectors. They don't have to be connected to the motherboard, just the power supply. In fact, if you have a bunch of case fans with the "pass through" connectors, it might not hurt to put one before each of said hard drives, to make the testing more intense.

I'm not citing ~20% off the top of my head. Airflow w/ and w/o wire grill was measured with an anenometer on a half dozen fans/sizes at different speeds. Others have confirmed with fingers-at-the-exhaust testing. Try a search on the forums for likely terms... particularly by Katana. This goes back probably at least a year, maybe >2.peterson wrote:I find that very hard to believe. From a stamped grill like the one on the back of the P150 i.e. perhaps, but from a wire grill?
