The blue wire in the CPU fan

seizetheday23 · 15 Jun 2012 at 15:34

Hello

I got a new system that has a intel stock cpu cooler.. Well the story goes like this. I got my system the other day and everything was going fine then i heard a random noise from the system i turned off the system asap and opened the case to find a blue wire that is apart of the stock cpu had got caught in the cpu fan blade. I pulled the blue wire away from the blade but the blade has cut this the fan is still going and the system seems to be running smooth. My questions are what is this blue wire? Will i have any damage to my cpu ? The blue wire is broke but everything seems to run ok should i try to mend this wire or buy new cpu cooler ?

The blue wire is the PWM signal wire. Without it the fan should stay at full speed all the time. If you repair it you should regain the ability to control the fan speed, if you choose to.

Thanks tealc. what would you do in my case ? Is it ok to leave at full speed ? Im thinking long term... AND will my processor have any damage from the cpu fan stopping ?

If you turned it off as soon as you heard something its likely not.

I would just get a new fan (or at least try to fix it) rather than letting it run at full.

Could you also recommend a good budget cooler than buying an other stock ????

Repairing is easy. Twist or solder then insulate with tape or heatshrink. Running full speed may cause the fan to fail earlier than if it were running at less than full speed. It's unlikely just to stop suddenly as fans usually show sign of wear by making a noise which will annoy you enough to replace a long time before it seizes.

Replacing is also easy, and probably a better idea if you like quieter running or lower temperatures, or both.

What sort of budget do you have for an upgrade to your cooler? How quiet and how cool do you want it?

This is a great budget cooler http://www.overclockers.co.uk/showproduct.php?prodid=HS-012-XG&groupid=701&catid=57&subcat=1395
