Okay I'm back. New fan still noisy. Thinking of looking at a more expensive one just for the sake of quietness.

New one just a simple one my daughter picked up, luckily it fit okay.

Someone mentioned about making sure it was the right size, I was just wondering how I would know if it was. What am I measuring exactly.

Would it seem silly to take my fan with me to the computer store and ask for one like that only quieter?

So what exactly did you change?

Assuming you have one case fan, put your finger on the center of the fan to stop it spinning momentarily and listen if its quieter, do the same with the cpu fan. NOTE: Don't stop the cpu fan for too long, just enough to judge the loudness.

This will give you a starting point as to what is noisy. Chances are its probably the CPU fan like you said earlier.

You don't necessarily have to bring the fan to the shop. If it is a CPU fan, all you need to tell them is what your CPU is. Each CPU type will have a "socket" associated with it, such as Socket 775, Socket 478, Socket 939, etc. Any CPU fan purchased needs to be compatible with your CPU socket.

What CPU are you using? And what is the computer make and model? Perhaps we can recommend what you should be looking for.

Thanks. I'll have a look inside over the weekend and try to get that information.

I'm an industrial chemist, so when my laptop fan started sounding like a cement mixer I designed a speciality lubricant for it. It's a blend of high grade silicones that is easy to apply, and which will do a far better job of lubricating your fan bearing than some old sewing machine oil or similar. Just do a search for Fanlube and you'll find our website with explanations of what goes wrong, and instructions and a video to show you how to fix the problem.

My noisy fan is the power supply fan... I bought a replacement fan (25 dBA sleeve bearing power case fan) Is it really that hard to replace?
