I am considering a Enermax Modu82+ 625, such PSU like most high-end Enermax PSU features HeatGuard that keep PSU fan running for 30-60 seconds after shut
down to dissipate the remaining system heat and prolonging system lifetime.
SPCR did not mentitioned it in their review, anyone has experience with it, is it bothering? Any idea of rpm, can you hear the fan when your pc is turned off?
You should be aware that the fans in the original Enermax 82+ lineup are producing ticking sounds for a lot of users here. Have a look at the thread associated with the review.
I have the Enermax 385W Pro 82+ and I don't notice the fan running for an extra 30 seconds, but the feature is possibly restricted to the Modu version.
