Did your paper cowl make a difference to the fan speed?
- nyanpasu64 5y agoListening to the two recordings, the one with the cowl has a very slightly higher fan speed (by less than 6%). I don't know if it cools the CPU better or worse at a given speed though.
- pubby 5y agoThe BIOS screen says the CPU fan runs at the same speed regardless of the cowl, but I'm not sure if this is accurately measuring RPM, or just estimating it from some other variable (e.g. the outgoing pulse-width modulation signal).
- NavinF 5y agoIf it’s a 3/4 pin fan and the motherboard is configured to treat it as such, then you’re looking at the real RPM. It’s easy to test by placing your finger on the center of the fan and watching the RPM go down.
