Sabertooth Z87/Z77 Fans Config?
Hi, I would like to know how the sabertooth z87/77 fans would be the best to config. Is it better to pull from the middle and push from the I/Os shield? Or vis-versa? Or just no fans at all, or one?
I have the Z77 Sabertooth and I do use those little fans. I know some people say they don't do anything for cooling, but I've tested having the fans disabled and then stressing the rig, then enabling the fans again and you can see a small drop in temps on the MoBo, Vcore and VCCIO. So based on that, I use them.
I have mine set up so the fan in the middle of the board is pushing air down under the thermal armor and the rear fan is pulling air out from under the armor and exhausting it out the back.
Hope this helps =)

Push air into the motherboard with your center assist fan. Exhaust air out of the motherboard with your rear I/O assist fan.
The rear fan doesn't have a dust filter, so if you use it as an intake, dust can potentially be blown directly onto your mobo components. Which sucks. So always use the rear fan as an exhaust. So naturally it follows that your middle assist fan should be intaking air from your case and shooting it into the board. If it was intaking air from the motherboard then your rear and middle fans would be fighting each other.
I have mine installed as it was designed by Asus to blow air in on both my assist fans. Both fans put positive pressure under the plastic covering the air escapes via the vents near the VRM's and MOFSETS, convention holes on the back side of the motherboard and the open areas of the Thermal Armor in which case your case airflow would remove that heat being moved from under the covering. The rear I/O fan would be more effective blowing air onto the VRM heatsink than acting as a exhaust. In addition I've had my system running for over a year with no accumulation of dust in those areas.
Here's a video of both assist fans installed as they were designed to be.
