Any attempt you make at trying to split up the control of your fans, for example: loop1rads, loop2rads, case fans, loop1pump, loop2pump, whatever else...You're going to be hard pressed to seperately control them all.
Sorry, it's my biggest beef tongue.gif PWM is the best way to control fans/pumps, but you have to diy your own controller or buy multiple fan controllers...

Why not just use Speedfan? Automatic software controlled fans FTW.

Not sure why everyone thinks static pressure is the only important specification. As long as the fan has sufficient static pressure to push air through the radiator, that is all that really matters. The MCR220-QP is a low FPI radiator, most fans should have sufficient static pressure when paired w/ it.

I replaced all my GT AP-15s w/ NB B12-Ps recently and couldn't be happier. The noise profile is 11ty better.

FWIW,

I had a Sunbeam Rheosmart running normal non PWM fans using Speedfan for a long time without any issue. It's a cheap way to make non PWM fans work like PWM fans especially if you already have the fans. Not the best built or looking controllers, but they are good enough to run around 10W a channel without getting too hot.

Martin, have you used the Rheosmart with Gentle Typhoons? They make up the bulk of my non-PWM fans and would be the ideal choice for my quiet rad fan needs.

I don't think Scythe knows how fast they'll have my, and so many other peoples', money if they can release PWM Gentle Typhoons. PWM AP-14s on rads and heatsinks, AP-13's as case fans. I'd pay a $5 premium per fan for it, even. A guy can dream...

Not GTs but I have with some yate loons which draw more power. I see no reason why it wouldn't work fine though. You could easily run 4 or 5 GTs per rheosmart channel. I will see if I can dig up the controller and try a GT or two. I took it down for some fan testing awhile back and need to pit it back in my system anyhow.

Do they have half-decent static pressure? I don't necessarily need monster pressure fans since the radiator in question only has 12 FPI, but even that little bit chokes up some otherwise quiet fans.

The Gelid Wing 12s have a static pressure of 2.66mmAq sound quiet and good for undervolting

Hm, not PWM though. If I'm going non-PWM then I already have Gentle Typhoons.

sadsmiley.gif if your mobo has only one 4 pin header, speedfan can still only control what is connected to that header. So if you have multiple banks of fans/pumps, you are SOL

Use splitters. A single PWM header should have no problems powering 3 low to medium speed fans off a single header. Most motherboards these days have more than one PWM header.
