I have a strange problem. The CPU fan mounting bracket on my AM2+ mobo keeps breaking. The first time happened about 6 months ago and the CPU fan had not been touched in about 2 years.
Since then I have purchased replacement mounts that only last about 2 weeks. I've tried two fans, both with the same result. A broken fan mount. Neither fan seems to be excessively wobbly or tight. There is not an excessive amount of thermal grease on the CPU.
- Any ideas on why this keeps happening?
- Has anyone bought a replacement bracket that lasts longer than a month?
- Any other clever solutions?
The mount breaks right at the point where the fan bracket hooks on.
The original mount bracket was stock. It came with the motherboard in 2009 (Gigabyte brand). The PC sits on a cement floor, never moves, and nobody used the room the room beside me. So, nobody should be drop kicking it or rattling it unnecessarily.
Until this latest breakage, I ran the PC standing on its bottom so the mobo was vertical (as designed). I thought perhaps the fan was weighing on the bracket so this last run I left the PC on its side on my workbench.
90-day followup, the blue mounting bracket off Amazon has yet to break. Nothing else has changed in my setup so I'm hoping that this is a sign that the problem was with the quality of the plastic used in the brackets. The black ones seem to have a super-high glass content which lends a nice brittle quality. For those interested in the magic blue bracket see here
