Well that's basically up to you. Do mind having them blowing at max rpm? I've never really cared to let my system control fan speeds or to mess with software so I grabbed a fan controller.

I just have mine running all the time. If the noise becomes a problem, then I'd suggest getting a fan controller vs hooking them up to your motherboard.

looks like my idle is 1.321V.

I'm going to guess that you don't have speedstep or the other power saving features enabled in your BIOS. If you get those settings enabled, your system will lower your multiplier when at idle and drop your voltages accordingly.

For example, with my i7 860, at load my cpu is at 4.0Ghz (191MHz x 21) and a cpu voltage of 1.325V. However, at idle it drops down to 1.7GHz (191MHz x 9) and a cpu voltage of 1.025. Knocking .3V off at idle greatly reduces my idle temperatures.

I was thinking about not hooking them up to the mobo as it would be way easier to run a molex string. Also, got the switch 810 today and it has a really cool "fan power distribution", for lack of a better term, pcb in the cable management area that will allow me to connect 7 fans, not using molex adapters, and then only connecting 1 molex plug to it. Really cool little idea. That will take care of most of my rad fans.

That's what I use on my 650D. Works great.

But as we were saying, if you're looking to not have them running at their full RPM then I'd suggest a fan controller. thumb.gif

Just purchased RS360 Rasa Kit + Extra RS240.

Rasa Kit CPU Block on i5-2500k
Danger Den GPU Block on GTX 560 TI

CPU: i5-2500k 4.5GHZ 1.38v
GPU: gtx 560 ti 1ghz core clock 1.1v

Tempatures while running prime95+furmark
CPU temp: ~60c
GPU temp: ~50c

Very happy with results, my first watercooled build smile.gif

PS: Guess I won the RNG game when it comes to pumps because mine is virtually silent.

Edit: Idle temps: ~25c on both CPU/GPU

this should be fine. Really don't want them at max RPM.

I am in a dilemma about fans..(I know they barely make a difference but I am going to be changing them out anyway).

I have a choice between 3 fans:(rad is mounted horizontally)

1.Yates High speed

2.XSPC Stock fans. IDK how to spell them but they are the Xiru-something fans.

3.These ultras I bought a while back when i didn't know about fans:

Fans can actually make quite a bit difference..

Yates are nice, but I would suggest a fan controller along with them. (Personal preference.)

Also, maybe consider some GT-AP14's or 15's. 1450RPM vs 1850, they move air VERY well, have good static pressure, and are BARELY audible. They're pricey but presumably the "best" fans you can buy. However, I use the stock XSPC fans, and GT's, love them both. No real experience with Yate's but XSPC fans on the RS rad, and my GT's on my RX, loop runs nice and cool.
