Color Classic Fan info?

[mraroid]

 Hi Folks....

Can anyone tell me the CFM and the dBA of the *original* Color Classic fan?

The original fan is 80 mm X 80 mm by 25 mm.  I believe the fan housing
can take at least 80 mm X 80 mm X 32 mm fan.

While I have my Color Classic apart, I thought I would install a fan
that is quieter, and if I am lucky, moves more air.  But I can not even
began to hunt for fans unless I know what the dBA and CFM of the
stock fan.

I strongly suspect that in the last 20 years, fans can move more air
and make less noise.  And they may be able to do it while drawing less
current.

I have looked high and low, but i am unable to find the CFM and DBA of
the original fan.

I have seen a replacement fan on a Color Classic FAQ.  It is a 80 mm X
80 mm X  25mm fan called a  PANAFLO FBA08A12L.  It is 12V, .1a, 1900
RPM, 21 dBA, and 24 CFM  But because I have no idea what the original
fan is, I do not know if this fan is noiser or moves more air around
or not.

Anyone have this information?  Anyone want to make an intelligent guess?

Thanks so much.

I have been unable to find out what the CFM and the dBA of the original Color Classic fan is.  While I am doing an upgrade, I would like to move more air and perhaps use a fan that makes less noise.

The fan most often referred to as a replacement fan for the color classic has a CFM rating of
24 and a dBA rating of 21.  How this compares to the original is unknown to me.

I found a after market fan that is the same size as the original fan in the color classic, and it is rated at 42.6 CFM and 25 dBA.  It cost $8.00.  For an additional $3.00 you can buy a rubber grommet to go around the outside of the fan to reduce vibration (or make one out of any kind of rubber or even cardboard).  You can also go to Lowells or Home Depot and pick up some rubber grommets that you can place around the screws to further reduce any kind of vibration noise.

It is a Lepa 80mm x 25mm 70D Cooling Fan, model number LP70D08R.

Here is the same fan on Amazon for $7.60 plus free shipping:

This fan is only 25mm thick.  The Color Classic house the original fan sits in, can support a 32 mm thick fan.  Bugger fan = more air movement, right? Right.  But it also means much more noise. I saw dBA numbers of 40 + wsith 32mm thick fans.  A bit too much or me.
