I have a theory that the tar preserved the plastics, because they were unusually good. So the whole thing got a long, hot wash, what could get scrubbed got scrubbed, etc., etc. When the fan was running and the fan was pushing through all that air, well, the place smelled like an ashtray.
RAPIDCLICK MAC CRACK
The ps was especially bad, as it had sucked all the smoke in and had the first crack at it, as it were. It was as if someone had rubbed it down with moly lube. I exaggerate only slightly when I say that the thing was coated inside and out with about a quarter inch of cigarette tar. It had to done, though, as the fellow I got it from was a chain smoker, had owned it from new, and the machine was literally brown. I used a handheld shower and hot, hot water. The ps wasn’t recapped, but it was thoroughly cleaned out. I am glad to hear that it is still doing its duty! Here is a picture of the old Panaflo beside the new NMB: The specs for the Delta are 34.0dB for the HH and 38.0dB for the VH. I went with the NMB fans as they seem to be a more modern design, and the specifications say they are only 30dB noise at 41.3 CFM. There is also a VH version rated at 42.02 CFM. The flange mount version fits both, I just wouldn't go crazy tightening the screws, but if you want to get a rib mount version there is the NMB 08025SA-12N-AA-D0.ĭelta have a 37.43 CFM fan that could also be a good option, Delta AUB0812HH flange, or AFB0812HH for a rib mount version.
RAPIDCLICK MAC MAC
The Sony Mac II power supplies have a rib mount fan, where the Astec has a flange mount. It is a vast improvement over the old fan, I can barely hear the fan over the noisy old hard drive. I've replaced one of the fans with an NMB 08025SA-12N-EL-D0, which is rated at 41.3CFM and is variable voltage from 6.0V to 13.8V. If I turn it up to 12V it is even louder and draws about 0.35A, 4.2W, so it is running at about half power at 9V. I removed one of the fans and put it on a variable bench power supply, at 9V it draws 0.23A, about 2W. For the Astec I measured the fan voltage at 10V.
For the Sony Mac II power supply, I measured the fan voltage at 9V when started up at room temperature. The power supply seems to be designed to pull air out of the computer, and blows it over a thermistor that controls the fan speed. The Mac IIfx power supply I have has a larger 92mm fan, Panaflo FBK-09A12H, which won't physically fit the Mac II power supplies.Īll the power supplies seem to have variable speed fan controllers. This is not the FBK, the FBH has a larger hub motor with small stubby fins, and probably has to spin faster to get the same air flow as a result. The Mac II power supplies I have, both the Sony and the Astec, have Panaflo FBH-08A12H fans.
