Then mine are downright chilly. CPU temp of 96F and system is at
a comfy 78F.
I just happen to have an AC line powered 4" fan in the
bottom front of my full tower case and I cut out the inner metal
to match the full area of the fan's intake then smoothed over the
edge using aluminum metal flue tape. The case looks perfectly stock
because I cut out the bottom of the front plastic (where there was
originally a very small cutout) as far as possible so its area was
as big or bigger than the fan. Next thing I did was to cut and hot
glue a piece of corrugated cardboard to the inside of the front so
that it set right above the fan, sealing it off from recirculating
any air from inside the case. I have to keep small bits of paper
away from the front or it vacuums them off the desk.
Major holes in the case where air could leak out were sealed off
with the metal tape. I yanked two cheap 4" 12 volt fans from dead
power supplies and mounted them in the ready made locations in the
top of the case above the power supply. The North Bridge chip on the
KG7-RAID has its own heatsink and fan. Other than the two cheap fans
in the top, the only other fan blowing out is in the power supply.
The CPU cooler is by Dr. Thermal and has a 5500 RPM fan. Quite a
fancy looking chunk of aluminum.
To operate the AC fan in the front (which moves enough air it shoves
a nice breeze three feet away in open air) I mounted a 12 volt
controlled
125V relay to a grid of cooling holes in the back of the case (stock
stuff, not made by me) right behind the CPU. A couple of Zip Ties
did the job. The AC wires are run directly into the power supply and
directly to the output of the EMI/RFI AC line input filter.
When the power button is punched, 12V from a disk drive connector
engages the relay which feeds 120~V to the front fan.
It's not overly noisy, and it's actually quieter than with the
old half dead Soyo Slot A board with dual CPU fans.
