OT: Removing fan from 486's power supply?

Gryphin:
Hey thanks, that's a good idea I haven't even thought about it As I said the computer is only an old 486 and I just took it from the storage so there's nothing important to backup.

Geoschmo:
Thanks, I'll check those. Perhaps I'll also remove the safety grid from the front of the fan.

Baron:
Hmm, I think a new special silent power supply to an ancient computer would be a bit exaggeration, even if I'd manage to found one somewhere.

Thermodyne:
Do you think it will still cool enough?

Sure. They manage to cool when they are packed full of schmegma, which cuts it back by more than 50%

OK. But when they're full of what? schmegma: bad command or word name for me

[Thermodyne]

In this use it means nasty stuff of dubious origins. It actually is the stuff left behind after a Hebrew circumcision.

These people have some other uses for the word warning---very crude rude and abusive

I still say go with a thermal resistor, worked great for me, almost soundless and has been working for years.

Technical data of Noise Killer

Supply voltage: 12Vdc +/- 20% (available in any PC)

Max. load current: 500 mA (more than enough!)

Standby power: approx. 25 % (saves energy!)

Maximum fan speed: > 97 % of nominal. (for maximum cooling)

Noise reduction: 15 - 20 dB !! (sounds like 75-90% less!).

Ambient temp: 0°C - 50°C. (better than hard disk specs)

Temp. control range: 36°C - 38°C (+/- 2°C). (extra stable when hot!)

Size of module: 26 x 40 x 12 mm. (easy to fit)

Short circuit protection; virtually fool proof (not necessary for you)

Start booster for reliable operation with all types of fans. (safety first)


costs approx $15 (130skr) unless you want to make it yourself wich is much cheaper.

Check the label, it should have a UL mark on it. One of the safety tests we do (abnormal operation - impairment of cooling) is disconnect the fan and check temperatures. Assuming it's UL listed, the power supply shouldn't explode or catch fire if you disconnect the fan. But there are no guarantees that it will continue to work if you do that.

EDIT: obselete post.

If you do try it, for Cliff's sake don't run the PC near anything flammable.

ANOTHER EDIT: Thermo's schmegma is also spelt/ pronounced "smegma" in medical circles. Not sure which Version is derived from which. This is the source of the wonderful range of smeggy insults coined by Red Dwarf, so smeg off, you smegging smegheads...

Is there any official page to this silencer? I'm not interested to fix and use time for that old pc which I don't use much anyway but it sounds very suitable for my main computer that also needs to be muffled down a bit.

Every day I learn something new, today this important and usefull word

Building on what geoschmo said about

making sure the fan blades and air vents are clean. A thin layer of dust is enough to cause a significant db increase in noise. Also make sure the fan is mounted tightly to the supply and the supply is mounted tightly to the cabniet as vibrations cause noise as well.

Check case cover and all of the drives. Make sure they do not vibrate.
