For fans I'd suggest maybe non-variable 1000RPM fans as a rough guide. That's usually more than enough air pushed with the added benefit they don't ramp up when the system is turned on to a lot higher thus noisier (like an 800RPM to 1800RPM would even if fans never exceed 1000RPM).
My fans never go above 800RPM (i7-3770K + GTX680).
