iMac Intel 21.5-inch, Mid 2010 in-depth cleaning
I am upgrading the CPU, GPU, HDD and RAM of my iMac.
Is compressed air and isopropyl alcohol enough for cleaning?
The dust got caught in between the CPU and the socket. Also the computer had an important drop in terms of performance.
How can I best clean the components of this machine?
Thanks in advance!
@francesco_ripa, I've cleaned many liquid spilled logic boards and learned a few tricks. Don't apply isopropyl alcohol onto a PCB that hasn't been "stripped". I'd suggest to clean the build-up dust with a tooth brush. If you have a used electric toothbrush, that's even better. Once all the caked-on dust are lifted, apply compressed air to blow off as much dust as possible. If there are still dirty spots, you can apply a small amount of isopropyl alcohol to the brush head then work those spots, section by section. A soft brush can really work as a polishing step to bring back the deep color of the PCB.
Doing this task is similar to polishing your favorite pair of boots. It's very satisfying. Take your time and enjoy the process!
@itsage, It's a really good job, I'm currently halfway through the upgrade, the courier hasn't delivered the SSD yet. The HDD after years of honorable service now has ridiculous performance, so much that it also slows down the newly installed CPU, GPU and RAM. However, it is much better than before, in terms of multitasking, the i5 is supported by 12 GB of Samsung memory.
I have followed these tips successfully. Thank you.
