Update: Fans and 4870 video card and Raid 1
Just a quick update: rearranged fans,
lower intake fan plugged into power
2 exhaust fans and upper intake plugged into chassis fans 1,2 and 3
cpu fan 1 into cpu fan and cpu fan 2 into power (left @ max revs)
ram fan plugged into power (max revs)
Tried Asus Qfan, which runs in bios and software. What a crap software, does not work properly. Googled around and could only find Speedfan. I was seriously looking at fan controllers, hardware but managed to get speedfan working enough for what I need
I found that if I toggle down what speedfan2 sees as Speed02, it pulls down all chassis fans (1,2 and 3). At ~60% I get down from ~1400rpm to 800-900rpm (as monitored in Speedfan and checking visually for rpm reduction. Asus pc probe (software fan reading) miscounts chassis3 for some reason.
Anyway, its working so far so good. With the 2 exhaust and mid intake fans on lower RPM, I still have the lower intake on max, temps not a problem, noise much reduced - but note that the noise with everything on max revs is much much less than the original 2 exhaust and 1 intake antec fans.
Briefly tried the Asus orange/white ports for a quick raid1 and it didn't like it, think its looking for windows on a 3rd drive which is pretty pointless for raid1 if you ask me. Going to try the "normal" sata ports and raid1 there. If its a hassle I'll just continue to use acronis.
The guys are flashing generic HD4870s with Asus Top Bios which gives a higher default clock in catalyst control panel (which an individual card may or may not be able to run without artifacting due to normal card variance) AND also gives a much better fan RPM control - idle is lower temps PLUS it auto ramps up when loaded, so its like the earlier work around but best of both worlds. I've not done it yet as I don't need it here, will see how it pans out with user experienceshttp://www.xtremesystems.org/forums/...d.php?t=196551
