In a message ken ross <[EMAIL PROTECTED]>writes: <<i ws installing another PCI card in my 7300 today & i found that the HD felt very hot ~ i've replaced the original 2 gig with a 4gig that'd only fit in the drive bay below, the only place i can see to fit an extra fan is an area with holes in just behind the HD ~ sort of a window into the PCI bay , if i put an extra fan in there which way should it blow ? extract from the HD area towards the PCI slots , or blow from PCI bay into the HD area ? >>
>From what I have been told the fan should be directed toward the CPU and PCI slots. The power supply fan sucks the hot air out of the hard drive compartment toward the rear and out through the vent holes in the back of the case. In reality I noticed little difference in which direction the fan was pointed. When I had a 1/3 height 4 GB Seagate in the lower bay the drive temp rarely exceeded 100 F even with the room temp of 85 F. Now with a 7200 RPM 1/3 height 18 GB WD the temp has reached 118 F at 85 F room temp. This is with the fan blowing toward the CPU. A 1/2 height drive would most likely run hotter. There is very little ventilation in that lower bay. You can also rig another fan at the front of the HD bay although it is a bit more difficult. http://www.xlr8yourmac.com/guest_rev1/ (fan info is at bottom of page) also see: http://www.geocities.com/glenstrek/7500_fan.html --glen (digest mode) -- PCI-PowerMacs is sponsored by <http://lowendmac.com/> and...
