(for now) Message-ID: <3370007@hpsgwp.sgp.hp.com> Date: 23 Jan 91 06:11:03 GMT References: <1991Jan21.215159.25118@d.cs.okstate.edu> Organization: HP Singapore IC Design Ctr Lines: 35 / ong@d.cs.okstate.edu (ONG ENG TENG) / 5:51 am Jan 22, 1991 / $ My only concern is the heat on the 386SX chip. The other $ chips are not emitting much heat. I bought a heatsink, but $ it don't seem to fit the cpu (0.75" by 0.75"). The cpu has emitted $ slightly more heat than when on 16MHz operation (after $ 15 minutes from OFF). I have the casing off, hence exposing $ the cpu, and I am going to leave it this way for 4 hours. If $ the cpu is still at acceptable heat level, I will close up the $ casing and give it similar burn time. Then maybe I will burn it $ in for 24 hours. Let you all know the results (you will hear $ me screaming if my cpu burns out). $ Just something for you to think about ...... It might be a better idea to keep the casing covered. If your concern is with getting rid of heat. Keeping the casing on doesn't trap the heat inside. Rather, it allows the cooling fan to have its proper effect --- sucking heat out from the system. My tower case 386 is stuff full with disk drives. I found that when I leave the cover open, the drive cluster get intolerably hot. So hot that a 5 1/4" floppy left in drive A: for two minutes got heated to the point where it start feeling a little soft ! With the cover closed, floppy no longer get heated.
