Antistatic packaging material is usually pink in color, its almost exclusively pink. So chances are the pink bubblestuff in the pics in the article are antistaticMikeC wrote:Hmmm... good point. I guess I need to make sure whatever I put in there is non-static...EvoFire wrote:Anyways... about ur bubble wrap.... I have to express my concerns for static. Its plastic and air, its going to develop static and your computer might be dead from the static shock.
Is this some kind of seriously twisted and sick sarcastic joke?

I'm more concerned about the brown snakes I saw down the back last week, but hopefully the red belly black will remove that problem.
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?

NICE! i like how you removed the psu grill... i think i may try that.Ralf Hutter wrote:HEY! I resemble that remark!!!

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 still see a psu-fan grill there...matva wrote: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:
True, but the expected time to live for any bug entering my appartment is still about 10 seconds, which is the average time i need to find something to swat it with and hunt it downdragmor wrote:Northern Europe is to cold for most of the nasties so your just not used to it.
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.

would it diminish to 22dba? 21dba? 20dba? 19dba?
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?

Is this based on a scientific test or just an estimation?jaganath wrote:Like I said, removing brass grills is only 1-2dB max, and for people with poor hearing sensitivity this is below the threshold of detection.
What do you think? This is Klaus Hurgelbergler here, PhD, with my massive lab of expensive acoustic testing equipment and anechoic chambers.Is this based on a scientific test or just an estimation?
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? Besides, it is fun, and makes the case look better (imo).
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?

Then i say removing them is 0dB.jaganath wrote:What do you think? This is Klaus Hurgelbergler here, PhD, with my massive lab of expensive acoustic testing equipment and anechoic chambers.Is this based on a scientific test or just an estimation?
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'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?
