Aaarrrrggghhhhh!!!!!
I have had my computer for less than two years.
Within 4 months of getting it, the CPU fan went.
Within a year, the fan on the video card went.
Both were on warranty. But I didn't get my computer back for 3 weeks and 2 weeks respectively.
Now, my CPU fan is going again(vibrating, noise).
The CPU fans are good fans (ball bearings not sleeves etc.)
Tried a couple of places to buy a replacement, don't have the same size amps/amps. Smaller fans but not my size.
Did buy a CPU fan with double the amp/wattage of the one I have. It is actually a case fan but I can install it as a CPU fan.
I now have a problem with the screws, as the new fan is twice as thick. And no one has the longer screws.
Will have to make do with different type of screws.
My computer sounds like a tractor under load.
Should have it fixed by tomorrow, so shouldn't miss any turns.
Didn't have this problem with all the Macs I bought in 20 years!
Greybeard, I certainly empathize with you.
