I just set up Prolimatech Megahalems cpu cooler and attached 1 x Delta 120mm Focussed Flow Fan (3 pin) that plugged into cpu pin header. I had attached 38mm fan clip x 2 that hold Delta fan from the bottom of the cpu cooler that blow airflow upward to the big exhaust fan at the top of my Antec 1200 case. I had set cpu fan as (voltage) and enabled in the bios.

At idle, the fan is quiet at 1700rpm and when under stress 4Ghz and the fan spin at 2700rpm (not 4000rpm) and got very nice cooling temperature on north bridge at 39C, cpu temp 37C and motherboard temp at 31C and core temp is idle at 29C, 27C, 29C, 27C and under stress at just 55C, 55C, 53C, 53C with an hour stress of linx. That's so amazing temperature with my room temperature of 23C! Why didn't I do it in the first place ?

However, I was worry about two things is: is placed heavy delta fan under bottom of cpu cooler is bad idea due to heavy weight? and is the cpu set to voltage reduce from 4000rpm to 2700rpm could burned out pin header cable ?

Okay, 4000rpm is very very loud, 1700rpm very quiet, 2700rpm is medium and fair (not too loud but could hear massive huge airflow blowing out)
That's the fan I use here: http://www.overclockers.co.uk/showproduct.php?prodid=FG-003-DE&groupid=701&catid=57&subcat=4

It'd be better it you hooked the Delta up to your PSU instead of a mobo header mate.

You must have really bad hearing if you think a fan spinning at 1700rpm is silent!!! :D
 
Yep, the delta fans can produce some great results, ive been using sharkoon silent eagle 2000's on various configurations of my rig. They can be loud according to people who hear them in my rig. I suffer from a bit of hearing loss due to doing a lot of shooting over the years without using proper hearing protection.
 
Deafness is a useful attribute when overclocking computers. Always a silver lining.

Your delta might burn out the motherboard header, either run it from a molex as suggested or check with gigabyte what current the header is rated for and compare with (power rating of fan)/12.
 
The Delta on the OCUK website is a FFB1212EHE which is rated at 24 watts / 2amps.. now that's the rated limited of headers on Asus boards not sure what motherboard you are using?

I had taken off Delta fan, because I don't want the voltage from cpu header to blew up ! Too risky.

I go back to standard normal fan to be on safe side.

Interesting here:

I had turn off and disabled 3 front fans, 2 rear fans on the Antec 1200 case and leave the top big fan 200mm on low speed and attached 1 fan of Scythe Kaze Jyuni 1900RPM Slip Stream at the bottom of the Prolimatech Megahalems cpu cooler facing upward to the big fan and pushed great airflow out of the top fan.

I was shocking as the system, north bridge and graphic card is very low temperature and had helped the cpu much cooling affect, just 67C on linx max or 65C on prime95 stress for 4 hours with my room temp of 23C on the 4Ghz overclock with 4 cores / 8 threads!. If I turn on all rest of 5 fans on Antec 1200 as the temperature will rise! Too bad airflow as system temp go up by 4 degrees, north bridge go up by 8 degrees and graphic card go up by 5 degrees!

Gladly I found that out myself.

I used to run an 80mm delta on my CPU a few years back, it gave awesome temps even when 7v modded but the sound was still pretty awful.

I'm sure they warn you not to connect them to the mobo header
