Hi autobun, Welcome to WindowsBBS. It is not normally the best way to clean a PSU using a tooth brush.
Compressed air (aerosol cans are available) is a more acceptable way to clean computers/hardware.
Always ensure the AC power is switched off and disconnected.
Any fans in the item to be cleaned/blown through, should be prevented from moving by using a soft plastic rod.
Bearings in the fan assembly will be accelerated beyond their normally acceptable levels and may in fact fail if this step is ignored!
Using a brush may have disturbed dust and caused it to collect in large clumps and gather in the fan assembly.
A rattling would seem to indicate something is out of alignment and making contact with another part.

You will need to provide more info on your comp and the OS you are using to enable us to help you further.

 

I agree with retiredlearner. I use a wooden Popsicle/glue stick to hold fans stationary then just blast clean with compressed air. It is important to hold them still or you risk damaging the bearings as they could easily spin faster than designed.

Rattling could mean damaged bearings in the fan(s). Or it could mean worn bearings in a hard drive. It could also mean you accidentally moved some wires in the PSU or PC case and now the fan blades are scraping the wires.

If you don't see anything obvious, you can very gently touch the center fan hub for just a second with your finger tip or wooden stick. This will cause the fan's rotation speed and that will change the rattling sound. If you don't hear any change in the noise, then it likely is not that fan.

Note many graphics cards also have fans, but they tend to be on the underside of the card and therefore are difficult to see.

For hard drive motors, of course you cannot see inside them. But you can carefully rest your finger on the drive and should then be able to feel the vibration. Just keep in mind even good hard drives vibrate a little and make a little noise (just a couple reasons to go with SSDs!).

 

The reason I suggested you provide more info on your comp is the fact that Bill brought up about HDD's.
If you have an older computer and it is running a Hard drive with spinning components - a rattling/clacking irregular sound may very well be a failing HDD!
Please Download Speccy and then Post the info on your comps specifications.
