I solved a very similar problem to this once by using a plastic cable
tie that I (somehow) threaded underneath the CPU socket. This worked
well for quite a while.
Of course, it wasn't my machine, so I don't know if it's still alive now.
I had a friend whose computer started doing all kinds of extremely
bizarre ***t, and finally began smoking. He later discovered his
processor had incinerated itself. Why? Well, the fan failed. Why? Well,
it threw three fan blades.
Don't ask me how that happened. By the way, that was not the machine
that had been Macgyvered with a cable tie.

Yeah, but if it's got a ballast, there's a massive inrush current, and
that can cause a brief voltage drop on the mains side of the circuit.
Like when you start a motor and the lights dim briefly (or like that
flimmer you get when running a laser printer).
