Hello all,

I'm just curious if anyone has an old system with no fans at all. You see I've got this little linux router of mine which has a p90 (actually a p100 running at 90Mhz) and it has a big electronics heatsink on it and no fan, however my PSU has a 40mm fan and the case has a 60mm fan.. And i'd just like the peace of mind knowing that it would still run ok if the fans failed...

So like I said anyone got a COMPLETELY passively cooled computer???

Thanks

Well, I have a 486 kicking around here someplace that doesn't even have a heatsink! Course, it was a whole 25Mhz, so I really don't know if you're good or not.

If your case fan took a dump.. it'll live. If your PSU fan did the same... It'll probably live too. It just wouldn't generate enough heat to cause a serious problem should the fans fail, IMHO. I could be wrong on that.. don't hold me to it. I've got an old P233 around... no fans except the PSU, and it's pretty faint (airflow & noise). The CPU has a heatsink on it, but it's pretty thin.

I have an old Packard Bell 486DX2 66. It has a passive HSF about the size of a greenie. It does get pretty hot some times.(I think its super glued on because there are no cips and I can't seem to get it off) Only 1 PSU fan that doesn't do anything but the PSU only powers components. Too far away form anything to provide any cooling and about 4 holes for air flow in the PSU.

dudes, yeah so long ago my friend had a p75 machine and the CPU fan died and he didnt notice until i pointed out his machince was uber quiet, but it actually ran ok, i also had like others, a Dx-2 50 with no cpu cooling, and ive even seen P2-233's (mitsubishi-apricot) with no fan on the processor only the psu fan to such air thru the system

Thanks all for replying.. I actually ran SETI on it for 12hrs and the air coming out of the box hardly got warm. I'm going to stick a temp probe in there and check again.

Once again thanks all.

oh and P.S. i would if i could afford it...
