4 years old - no dust at all?

[EdGey]

Hello,

I'm salvaging a PSU from my old system and upon taking it out - noticed that the internals and fan are sparkling new. Like factory new...

It looks to me like the fan hasn't spun once in its life despite the hot summers we've had.

The PC has had a number of unexplained crashes in its lifetime - could this be attributed to a broken PSU fan? Or are PSU's these days just so efficient that the fan is barely needed / barely spins at all even under heavy load and hot conditions? The rest of the PC is caked in dust.

It's an RM750 corsair psu.

Thanks

I've done a bit more research - it seems that corsair actually recalled a bunch of the rm750 series due to a problem where the unit would over heat and shut down before the fan started spinning. It turns out that my serial number is included in those recalled.

So that just about explains it! I've contacted corsair and I can only assume they'll replace it. I'm glad I noticed before I put it into the new system.
