Does the system have a large heatsink and fan on the CPU, and does that draw in air from vents in the side of the case, If so, then you probably do not need a fan to extract air from the case. The 'modern'? idea seems to be to pressure the case with air drawn in directly to the components generating the most heat,and let that flow out past the rest of the components. The old ( couple of years ago ) idea was to draw out hot air, which would be replaced by air from all around the case drawn over all components.
The new technique is generally superior, providing you don't also have other fans attempting to draw in air - such as those in hard drive caddys, in which case they will probably be fighting the main air flow arising from the large CPU fan JimB ----- Original Message ----- From: "Sam Franc" <[EMAIL PROTECTED]> To: <[email protected]> Sent: Sunday, July 02, 2006 5:26 PM Subject: HARD:Case Fan needed? > my daughters HP computer came without a case fan. > Here is the reply she got from HP. > > > > > Susan, > > > > Thank you for writing back. > > > > I had reviewed the specifications of your computer and found that the Mother board is equipped with Heat sink and does not require any fan.
