FOXCONN Launches BLACKOPS Intel X48 Enthusiast Motherboard

[gmcg]

AMEN!!
Having the BlackOps NB aircooled with the supplied tiny fan just don't cut it. its crazy loud, and grossly inefficient to say the least, with temps in excess of 47C IDLE. That leaves just the water cooling for us non-LN2 users, then this happens...

Any comments Quantum Force "Scholars"?

I want to confirm your statement about loudness/efficiency of the stock NB fan with it's specification, my fan is AFB0512HHD:
http://www.delta.com.tw/product/cp/d...50x50x20mm.pdf

As we can see, it has 6400 RPM with 12V and max CFM 18.3 (0.518 m3/min) having 37dB of noise at that speed - according to specification. Such as being installed it is located really close to the cooler, the pressure goes up, as well as CFM goes down according to the graph on specification and noise of flowing air with turbulence becomes like twice louder than 37dB in specification.

Please understand me correctly, I don't want to blame the board (having 790i before, LOL), but the air-cooling version of 4in1 Quantum definitely needs a modification for silent and more efficient operations, as well as to be "all-copper" for WC (or at least delrin-copper, acrylic-copper).

Used by me SilenX IXP-54-14 fan has only 14dB of noise at 32 CFM@1700RPM, and I have located it not so close to the cooler using 40mm spacers (pressure stays low enough, as well as noise due to significantly less turbulence), therefore noise and airflow are the same as on specification. The dissipating surface is more than doubled with attached 8 ramsinks, it means with the doubled airflow (32CFM vs 18.3 down to approximately 16 or less due to a raised pressure level) the system becomes at least 4 times more efficient being almost silent, such as level of noise it depressed by -23dB or significantly more taking in mind the additional air flow noise due to close location of the stock fan. I used spacers like those:

I have some professional calibrated equipment to measure the difference in noise levels for the same conditions, but it is not necessary ATM. BTW the stock 780i/790i cooler fan is pretty loud also.
