I have a small problem that I hope one of you can provide advice to.
I have what I believe to be a failing fan, either CPU or graphics card. How can I identify which one it is ?
If need be I will swap out both of them, but it goes against my nature. I like to know why I am replacing something.
Both have had less than a year of use, the graphics card was bought about a month before the new CPU cooler.
Problem appeared when both were less than 6 months old with a high-pitched whine under CPU/GPU intensive conditions.
In the last couple of days it has become more pronounced, being noticeable in normal use.
And yesterday and today there was a pronounced grating sound when starting up. Failed fan bearing from the sounds of it.
However switching off the computer rapidly and, then after they have run down, turning the fans manually I cannot detect any rough feeling on either of them. Sometimes after doing this, it will power up without the noise happening again. Sometimes I have to repeat the process a couple of times.
If I can get it to power up without the noise, then it will run for hours without problems.
Any ideas on next step?
