EP45-UD3R Won't Allow Controlling Of Fan Speeds

You need fans with a switch to control the speed or plug them into a simple fan controller.

Bilbat (in this forum) has some tricks to re-wire fans but that's the only other option.

Ya I would actually go for the re-wiring trick, because I want to keep the fans, but them operating at constant full power is simply to loud. I someone would direct me to the page where you, Bilbat, explain this; that would be greatly appreciated

If you need more help, post back...

took a look at that and deemed it to complicated. Thank you for diagnosing my problem, now I am off to find a do-able solution!

ckaz, it's not as tricky as it seems.

Try this at least to see if worth messing with. Make sure one of your new fans is plugged into the SYS_FAN2 header. Disconnect the other one - not the CPU fan! - to keep their sound from intruding. If you've got a fan on SYS_FAN2 now, plug it into another header. You'll see two things from this. First is whether the new loud fan can be controlled well from BIOS and/or a program - make sure you've enabled fan speed control in the BIOS.

If the new fan works well with control - and the old fan if it exists doesn't become a howling demon - then you know that's the solution you want.

With the rewiring, you don't even have to connect the 3 wire from another header - this only displays the RPM. So you can control both fans from the single header just by splicing their other two wires together.

But at least test plugging one of them into the controllable header as an experiement.

I don't know if you followed this link in the other post:

but these make the job dead simple... Another possibility is to just use these:
120mm: http://www.newegg.com/Product/Product.aspx?Item=N82E168...
92mm: http://www.newegg.com/Product/Product.aspx?Item=N82E168...
which you can 'daisy chain' onto your CPU_FAN header, and have the whole shebang run dependant on your CPU temp; they come with these plugs already installed:

and they have a page regarding the technology here:
http://www.arctic-cooling.com/catalog/product_info.php?...
and a couple of more pages of detail here:
http://www.arctic-cooling.com/catalog/product_info.php?...
and here:

the 120s are available in both 'tunnel' type mounts (where the fan is inside a cylindrical shroud - better for intake and radiator fans), and 'cage' type (better for exhaust fans), and they are all pretty quiet; the cage type uses a conical rubber isolating pin in all four corners to keep bearing and armature noise from being transmitted into the case panel...

bilbat, I think the product you want to link to is this one:

The other link would allow one fan to connect to two sources or be used to hook in a controller I believe. The link I added allows two fans to run from a single header, which I think is what most people are looking for when they order the other wiring.

The Arctic Cooling devices are nifty! I guess there's no issue of enough amperage coming off the CPU/PWM connector to run several fans - rather like my old questions about adding extra splitters on a drive power cable.

One thing I'm still not clear on is whether a non-PWM fan can be converted to one.

Eeek! You're right; I blame it on NewEgg's search mechanism! But, I'm glad you pointed it out, as I mainly buy these things to 'peel' them for the connectors, and I'm always short of the females that plug into the MOBO headers - now I know how to 'double up' when restocking  
Arctic says any fan header is good for five of 'em, and I think that's pretty conservative - here's something I hunted down for a post at TweakTown a year ago:
"PWM JEDEC spec says MOBO PWM headers 'should' supply 1.5A steady-state, and tolerate a 2.2A start-up surge. Most of the fans I've checked seem to run around .11 to .16 A, so several should be OK. Your mileage may vary. Good luck trying to find your MOBO's spec for this!"

A regular fan cannot be 'converted' to PWM - think of a PWM as a 'remote controlled valve' - the small, no current 5V control signal operates switches, on-board the fan itself, to control the higher current 12V supplied to it. GB's setup on the SYS_FAN2 (SYS_FAN1, on some of the AMD MOBOs) is pretty ingenious, though - it works with either kind. The 5V PWM controlling signal is 'locked full on' (simply supplied a steady 5V), and the 12V supply line is then modulated to control the fan; only problem - it 'hiccups' with some varieties of PWM fans, who apparently 'don't like' their 12V supply being switched... Now that I think about it, nearly any PWM fan should work off a regular 3 pin header, if you run 5V to the PWM's pin four!

Here's another interesting piece:

Ok now you guys have really lost me  

I would really rather not have to buy anything online, so for now I'm going to try and work around that option as much as possible.
Please explain this to me. I should plug "one" of my new fans into SYS_FAN2, and unplug my other loud one from wherever it was. What exactly will this prove?
And am I able to be unplugging fans and plugging in fans while the comp is on, or at least on sleep? Or do I have to shutdown everytime I open up the case.

If you plug one into SYS_FAN2, you will find out if you can control it, RPMwise... And, no, I don't recommend doing anything like that 'live'; if you slip, fumble, or make any minor error doing it on a powered down board, it remains a minor mishap; if the board is 'hot', it can become 'devastating' pretty much instantaneously!

Thanks for the answer on PWM bilbat.

ckaz,
Never do anything live if you can avoid it. And to make sure your motherboard is REALLY dead, either turn off the switch on the power supply or unplug the AC cord. The front panel switch doesn't turn off the system fully even when set it BIOS to do a full power off.

Yes, plug in one of the airplane fans into the controllable Sys_Fan2 to test it. And you can leave the case off - if your system doesn't like that, there's a BIOS setting to allow it to ignore the case cover.

If you like the control you gain on the one fan, consider getting one of these in some future purchase - either online or in a real computer tech store. What's the thing about buying online?

Alright, after much difficulty, I have come to the conclusion that I will be, to my great loath, buying a fan controller online. First, I tried doing what you said about plugging a fan into sys_fan2, but due to many complications, I couldn't. The reason why I HATE buying online, is because so many to of the things I have bought have come faulty, and the I hate waiting for the RMA, not to mention the fee for shipping. In fact, I just realized my speakers are faulty, but the reason I only realized it now is because it took me weeks of testing to come to the conclusion, but its been a while since i've bought it, so I can't see them taking them back. Here is the fan controller I will be buying.

Well, it certainly looks like a dandy. Don't know anything about em, amazed that Scythe seems to make a dozen models! That one looks like top-of-the-line.

In the US, the cost of shipping is often equaled by the savings in sales tax, so often not a big deal. Besides, the price of the items is generally well under the price at super-stores.
