Magnetizing a cpu heat sink

In regards to my plan of having a detachable cpu fan, would using weak magnets to attach a removable fan directly to the heatsink cause issues with the cpu. 

 

... i know this is an odd plan and probably not recommended fan layout, but my case design is pretty much locked in at this point and want to test idea of a passive fan with optional direct connect fan as backup.

it might affect the fans since fans literally has magnets in them. though i dont think it will affect it that much. though electronics and magnets is a different discussion altogether. 

Im with the mentaility of "IF IM NOT SURE IF ITS ENOUGH COOLING, GO OVERKILL"

and a whole lot of LED everywhere(behind the monitor, behind the desk, behind the shelf of the PC mount and inside the case)

Other than magnets, any ideas on quick and clean looking way to connect a fan to heatsink. while only having access to the top.

 

i might just start throwing magnets at one of my old builds; heatsinks, and see how they hold up.

hot glue and Velcro? it dampens vibration sounds too!

I've put neodymium magnets directly on PCB's and motherboards with no effect, on a heatsink there will be no issue. Using a matching set so the N and S poles stick together onto the heatsink with the fan would be your best bet. Only thing I've recommend against is to have it on a hard drive itself, while even the most powerful small neodymium magnets shouldn't have any consequence it's best to avoid the possibility of problems with ones data.

Awesome, thanks for your advice. I prefer magnets over velcro for aesthetic reasons so this is good to hear.
