the temp monitoring you are using won't show the temp of the psu
fix it soon or you'll be up for a new psu if not more

3 things you could do
************************************************** ******
warning: this isn't for a novice and you could trash your entire system if you get it wrong or damage another component
you could also give yourself a spikey haircut and bruises when you hit the wall on the other side of the room if the psu gives you a boot
************************************************** *******
1. get a job, buy a new one

2. remove the psu from the machine
best leave it for a day to let the juice run out of it
DONT touch any of the capacitors inside the psu
unscrew the fan and remove (some are connected with a plug, others are soldered to the board but the wires will be long enough to remove it to work on)
clean all dust etc with a toothbrush and compressed or canned air if you have access to some
check the fan turns ok, if the bearing casing (if it has bearings) has collapsed, it will have to be replaced
remove the sticker on the fan then pull the rubber plug
apply about 4 drops of 3 in 1 oil give it a few spins to free things up, replace the plug clean oil off and put a new sticker or some tape on it

reassemble and power it up

3. if it still doesn't work, you'll have to replace it
Dick Smiths have them usually 80mm - 100mm depending on the brand
www.dse.co.nz
if its one with a plug, no sweat
if it's hardwired you'll have to cut the wires and solder the new one on or use a connector
make sure you tape the joints up well

if you kill yourself while doing this, don't PM me I'll be on holiday

************************************************** ******* LOL :lol: I have done that once or twice and I DONT reccomend it, it leaves you dizzy for about an hour depending on the current.

What about taking the side cover off and using a large desktop fan, (if you have you available) to blow inside for a temp fix.

HTH :thumbs:

417542 2006-01-03 00:17:00 Buy a new PSU... it is not worth the effort or the potential danger and damage you can inflict on yourself or the rest of your PC components.

PSU's are not to be taken likely, if you don't have the money for a replacement (new or 2nd hand) then I'd suggest you don't play around with it until you can source another one. If you can't wait you may find yourself having to replace a whole comuter system.

Just some friendly advice.

cheers

417543 2006-01-03 00:32:00 I won't bother with cleaning. Did that on a week or such ago took it apart and man the dust was stubborn but in our case the fans were still spinning, it was just v dusty. We used a vacuum cleaner and then just gave up. Compressed air .. with brush, that would take a while. Looks like I need CRC or detergent! :waughh: Nomad (952)

fix it soon or you'll be up for a new psu if not moreWhy won't it show the temp? And how the heck do you know what sort of monitoring it's using? Besides a PSU can go sometimes for hours without its own fan. And his motherboard might have a function that warns him when the temp exceeds allowable temps.


1. get a job, buy a new oneI don't think he was asking for employment guidance.


2. remove the psu from the machine
best leave it for a day to let the juice run out of itI am pretty sure that 30 seconds would be ample time to let out any left over current.


clean all dust etc with a toothbrush That sounds about the equivilent of using a jackhammer to open a can of sardines. A soft artist's brush would be more suitable.


apply about 4 drops of 3 in 1 oilThat's way too much - less than a single drop would be ideal


make sure you tape the joints up wellWhy on Earth would you put a meltable product like tape into a PSU!!!?

417545 2006-01-03 03:34:00 There's some seriously bad advice there!

and some real ignorant advice that followed!


Why won't it show the temp?

The vast majority of MOBO's don't have psu temp monitoring capabilities


And how the heck do you know what sort of monitoring it's using?

i don't, i'm making an assumption, much like you are by assuming you actually know what you're talking about


Besides a PSU can go sometimes for hours without its own fan.

yeah....and your point is.....?
sometimes they won't go for hours as well


And his motherboard might have a function that warns him when the temp exceeds allowable temps.

highly unlikely


I am pretty sure that 30 seconds would be ample time to let out any left over current.

that's about the biggest dumbass comment you've made yet!
only a fool would touch the capacitors inside a psu within 30secs
the safest way to discharge a psu is to leave it unplugged for 24hrs
Or, get a PSU tester, and leave it plugged in the PSU for at least 20 minutes
tell ya what whip your cover off now, have a play and get back to me on the outcome


That sounds about the equivilent of using a jackhammer to open a can of sardines. A soft artist's brush would be more suitable.

LMAO, i'd like to see you get a couple of years of gunge off a psu fan with an ...artists brush, did you say?


That's way too much - less than a single drop would be ideal

1. i said about, some fans have quite deep recesses and would easily take 4 drops once the fan has been spun around a few times and it's soaked in
2. better to put enogh in then clean it off if it oozes out than not enough and have to strip it down again
3. how in hells name do you put "less than a single drop" in?


Why on Earth would you put a meltable product like tape into a PSU!!!?
ever seen inside one?
most of what's in there is meltable, thats one of the reasons they have a fan.. to keep them cool
i will concede, that sleeving the soldered joints would be preferable but most wouldn't have the gear to do it

a tip for you sunshine...
if you're inexperienced and don't know what you're talking about, as you obviously are, then ignoring the post is the better way to go
i've replaced dozens of psu fans with no problems yet, mind you my customers are probably all dead, so they can't really complain can they?

417546 2006-01-03 09:03:00 Jeez that was a lot of wind without saying anything remotely bordering on intelligible! haha Got a lot of time on your hands then?

Anyway, all I was saying was that anybody who took your advice above would have to be in a pretty desperate state. Or soon would be. Don't be so touchy, fairy!
