New build startup - Couple of questions

[martian_aphid]

Ok so kept my fingers crossed pressed the start button and yay! my first POSTed, thanks to all for past advice =D

BIOS reads temps on the Q6600 at 44degrees with TT at full

Anyway just wanted to ask a couple of things - chassis fans, dumb question but just checking, I assume these need to be plugged into the molex connector as well as the 3pin connector on the mobo as they aren't spinning atm?

Second question, before I install the OS should I be setting the SATA optical and HDD to AHCI [would it be necessary for an esata hdd]?

btw safe to daisy-chain 4 fans on one molex?

Thanks for the info soulhunter, I plan on using an external HDD through esata. I know that AHCI allows hot-swapping of SATA drives, not sure if esata is classified as that but I'm guessing it might be. The reason I asked before installing windows is that I heard switching to AHCI after installing windows would cause the drives to fail to boot and require repairing the installation.

I guess I wasn't thinking about the chassis fans, I just assumed they ran off the mobo like the CPU fan but now I realised there's only one wire on the 3-pin :S Anyway I will try daisy-chaining these two case fans in with the other 2 already on the molex for a total of 4. My PSU is 800W with 20A on the 12v rails, 64A combined.
