2 Quick Questions CPU Fan

Specs: Microsoft Windows XP Professional, 1.6 GHz / 767 MB
Okay, my CPU's heatsync fan started going round slowly yesterday and after finding that my CPU temp slowly goes up with no stop, I had to leave my computer alone ('cept for the quick bios setup to fix my CD drive).

After fiddling with the fan a bit (after taking it out of the PC) I managed to get it spinning properly... Well, I think so. Not sure if it's as fast...

My question is, how safe is this thing gonna be? I had to do some wedging of the fan to move it away from the base to get it to spin properly when I first fixed it, but then after screwing the thing back into the sync it started acting up again so I pulled it away.

I managed to fix it literally minutes before heading off to buy a new one. I'm kinda upset I actually fixed it as I could have maybe gotten a better one... But should I maybe think about getting a new one anyway? Is there any way I can safely keep the fan from hitting the back again? How likely is it that it would stop during use, even on a flat surface?

ATM, I'm leaving the computer on BIOS > PC Health for a while to see what temperature it rests at and so I can turn it off easily if the thing gets stuck or something and I've found it's running hotter than usual. It's at around 48 degrees which is about 10 degrees hotter than usual. Is this an okay temperature? How much higher could it go? (RPM = about 3800)

By the way, to all the people who kindly helped on my overclocking topic, it's not overclocked atm / nor underclocked ;)

The other question is simply, should I disable Spread Spectrum off when I overclock my PC? I read up that I should always do this although I wasn't informed so while overclocking.

I found this in a book about my CPU that I read for the first time ever (I hate reading) which was pretty helpful although I think I don't have the motherboard that the book is also for... Yet the bios is the same (ish) :D

"After fiddling with the fan a bit (after taking it out of the PC) I managed to get it spinning properly... Well, I think so. Not sure if it's as fast..."

What do you mean by "fiddling"? If anything, you should have removed the fan from the heatsink, cleaned it, peeled back the label that seals the bearing, added a single drop of oil, worked it in by rotating the blade, then sealed it up & put it all back together. If it wasn't rubbing on anything before you took it apart, it shouldn't have been rubbing on anything after you put it back together. There was no "wedge" in before you worked on it, right? You obviously did something wrong.

Always disable Spread Spectrum...ALWAYS! - whether you're overclocking or not. It's only enabled by default because of FCC regulations.

I took it off, tried to clean it and spin it around a bit to fix it, plugged it in and it didn't work. Then I took it out again, looked for another fan to use, couldn't find one, decided that I'd buy one the next day and then I wedged at it with a screwdriver... I thought I probably wasn't gonna be able to fix it by that point so I decided to just use force with it then I attached it to power and it spun right...

I don't really have many PC repairing tools around the house. I just want to be able to make programs without interruption. The fact I've ended up learning ways to configure the BIOS and messing around with hardware is accidental and I just learnt it cause I had to using the hands on method.

Nice that I know about the spread spectrum now... The thing is that nearly every one of my deafault BIOS settings are the wrong thing. Returning to default even underclocks and disables everything on it.

BIOS defaults are never the best performance settings...they are NEVER 100% correct. They should only be used as a starting point. If you "fiddle" with the settings & screw something up, all you need to do is reset the BIOS by using the ClearCMOS jumper & you'll be right back to the defaults again. You can't damage a system by using incorrect BIOS settings, UNLESS you crank up the voltage too high.
