i ahve this old computer, im turing it into a monowall firewall.
getting a 8meg cf card with cf-ide adaptor.
gettign a bigger heatsink to passivly cool the 150mhz pentium (basicly the stock cooler for a 2100+ athlon without the fan)
and so far its silent apart fromt eh psu fan.
i stop it with my finger and the computer is silent.
i dont know what the wattage of the psu is, but it doubt its more than 200w.
most likly only 100-150w.
but um, can i savely passivly cool it?

can be done. however what i sugest is a very slow fan. you still need some air movement (to cool cpu and other componants) so you still need a fan. a nice quiet slow fan would do the job.

edit: you may want to trim the psu fan grill to cut down the noise as well (use wire grill).

when cleaning the computer (it had like really think dust caked onto everythign) i just got some tin snips and cut teh fan grill off.
gar the case is sooo poorly designed, i dont know how people survived back then, i mean the sides and top of teh case is one massive bit of sheet metal folded into a U and then screwed on, the drive bays are also one peice of metal...
if i coudl find the usb cable for my camera id post a picture of the case, its messy as hell, and thats with no wires in it.
the psu mentions soemthign abuot ktx? and i couldnt find any info abuot a ktx standard on wikipedia...
nice thing i do like though is thats the mobo just pops out on a tray along with teh backpanel that the pci/isa cards are attached to.
thats 3 screws on teh site of teh case that the back of the mobo is attached to, and 4 screws from the back, aswel as teh screws to open the case.
onceyou take everything out the case bascily falls over its sooo flimsy.
ill post the image in a few min once i get my mate to host them on his website.

are your sure the case is poorly designed? a lot of the early ones have better cooling solutions than the modern ones and the the modern ones NEED the cooling.

well the drivebays block the fan of teh cpu, so thats a flaw imho

I would get a 120mm fan (Vantec Stealth) and a 80mm to 120mm fan adapter and mount it on the outside of the PSU, the Stealth fans are really quiet and they'll move a sufficient amount of air to keep the PSU and its components cool.

Just my :2cents: worth

I have a system to almost the exact design, one big and slow fan to keep it all cool, almost slient. I can hear it at night if i am with in a few feet of it.
