Psycho101,
Thanks for your reply.
>I wouldn't want to put more than 0.75 amp through a fan header.
The Arctic Cooling AF 12025 PWM draws .13 Amps at 12 Volts.

The UD5 manual lists the CPU_FAN as 4 pin and supplying 12 volts. SYS_FAN1, NB_FAN,PWR_FAN supply 12 volts and are 3 pin. SYS_FAN3 is 3 pin, but the voltage is not mentioned. SYS_FAN2, the only other 4 pin fan is 5 volt.
Since I posted here I did get lucky with a Google search and found a post that mentioned each fan header can handle 3 amps at 12 volts.

Can anyone confirm this?

Here is a link to the xbitlabs study comparing various supercoolers with a core I7 920 at 3.76GHz/1.275V
Prolimatech Megahalems and 12 Other Coolers for Intel Core i7 Overclocking (page 18) - X-bit labs
The Thermalright IFX-14 is currently at the top of my list.
The Corsair H50 was a consideration and I looked at several reviews. My impression was that although a good choice in certain situations, it is inferior to the better air coolers in a well ventilated case - I already have an Antec P193 sitting here in my room. There is also the additional mechanical complexity.
The important criticism of the P193 is the tallest tower coolers won't fit. I can tell you with a small hex wrench and 4 flat washers the P193 can be quickly, easily and reversibly modified to handle the tallest coolers (of course, the case may appear to be badly in need of a support bra).
