Sometymes less is more...
 
All things being equal, the less you have inside your computer...the more aire you have, and thus the cooler it runs. That. of course, assumes everything else is the same. So here's my attempt at increasing the aire flow...what do you think?:o

very clean look, only 1 HDD?

Sharpside 1st August 2005 22:44

Nice and clean, abselutly the opposite of my case :)

tnvtnv 1st August 2005 22:49

only one h/d?
 
No, there are two (2) raptor 75's, the second is behind the removable mobo plate.

What case are you using?

tnvtnv 14th August 2005 13:56

my case, another change
 
The case was once a Flower 201-b. I find that there is still more to remove, so I removed the offending member (3 1/2" enclosure) and added another fan in the front. Now there is aire blowing directly onto the mobo. I don't know if it helps, the benches are still the same, as are the mbm5 stats...still...I like it.

maybe a closer view
 
Here's directly from the side...

one last picture
 
In it's natural surroundings...

tnvtnv 14th August 2005 14:03

sorry, missed the pic.
 
Now in it's natural surroundings...

Leonardo rules :p

Temp & sound measurements are keys, but at the very least it certainly looks clean and sexy :)

tnvtnv 14th August 2005 18:46

temps and db
 
My digital soundmeter (radioshack) shows 23 db (c weighted) 3' from the front, 21.5 from the side.
Room temp. is 76.4f/case temp. is 83f/cpu temp (running Prime 98 for 20 minutes) is 105f.
Measurments on MBM5. tnv

c weighted does not reflect humar hearing; do you have a weighting also? :)

tnvtnv 15th August 2005 00:26

c vrs. a
 
It has both, but the instructions included with the unit said to use "c" and so that's what I did. Sorry, I'll cheque and post the "a" weighted reading shortly. tnv

tnvtnv 15th August 2005 01:07

a vrs. c revisited
 
I called a friend who is a sound eng. and asked him why the "c weighted" measurment was recommended by Radioshack if it wasn't within human usable range. He explained it as follows:
The A, B and C weightings mainly differ in the degree of sensitivity at lower frequencies, relative to 1000Hz. The least sensitivity to lower frequencies is provided by the A-scale, the most by the C-scale. The D-scale gives an indication of perceived noisiness and is used in aircraft noise measurements.
So, as I understand him, using the "c weighted" was correct, since I was measuring a wider freq. then the "a wighted" and I can hear well below 1000hz. If anythng, the "c weighted" reading would actually have a higher db reading then the "a weighted" reading tnv

Since A weighting is thought to provide the most accurate model of how the human ear perceives loudness, and noise that causes hearing damage correlates most closely to the A curve, the A network is usually specified in federal government regulations established by the Occupational Safety and Health Administration (OSHA)

thank you
 
Thanks for all the info. The next tyme the Occupational Safety and Health Administration (OSHA) visits my house to cheque for hearing damage caused by my computer...I will make sure they're using the "a weighted" scale on their meters. However...unless the neighbors complain...I don't think I will be visited by them in the near future. I'll visit this forum sometyme again in the future. tnkx...tnv
