As soon as the PSU heats a bit up, the fan spins fast enough to be in the expected range.
QuoteAs soon as the PSU heats a bit up, the fan spins fast enough to be in the expected range.That sounds like a sick (in the old fashion use of the word) PSU. You need to find out what is changing when it heats up. Is it the FAN heating up, or is it the PSU. If it were the latter then it needs replacing as they should not do that. It also applies to fans.It looks to me like you are getting your early warning now.
Sounds like a standard heat controller fan PSU to me.Most PSUs these days have a build in fan controller that runs the fan at slow speed when cold, then if/when the PSU starts heating up (like when your computer goes from an idle load of 50w to a full power load of >300w) it spins the fan faster.Probably 90% of the non-crap PSUs sold these days do it.
