Personally i think it will e a while before desktops are gone. They won't disappear completely, but my guess is that they will be about 10~15% of annual PC sales within 3-4 years. If we are unlucky enough the PC gaming-scene might largely die off to consoles though. Games are already released to co...

it makes me sad that large desktops are phasing out. I love my desktop! However, the statement doesn't surprise me...it's already looking like I will never own an ATX board after this one.

RoGuE, DAve_M, rpsgc, ATWindsor -- Please, let's just agree to disagree. I think both sides have made their valid points abundantly clear. My assessment of the 1005HA was on its overall merits, not only noise, which I felt (and still do, having used it earlier this morn) is quiet enough even though...

Everywhere you can show me a fan-less design, I can show you reasons why. The fact remains that Asus weighed their options, and chose to include a fan to keep temperatures in check. Comparing different net-books doesn't help your argument. Like I said earlier, different chip-sets, different mass an...

It's an enclosure for electronics that is both thin and lightweight, yes, and now I am getting back to you. Well? And it has a Core 2 Solo or a Core 2 Duo, not a puny underpowered Atom.

Just to get this straight, the "smooth and quiet 20 dbA" was achieved when you had the cooling capacity to run full load? So one could envision a setup where it is as quiet ass possible most of the time (when its not on full load), but it ramps up to "smooth and quiet" on full load? I set the fan s...

I'm not sure i am following you? At 700 rpm (7 V approx), the HR-01 is a better cooler than the TRUE on the pentium, it should be a better cooler at 7V for a i920 too? Regardless of CPU, the cooler will dissipate the same amount of heat with the same fanspeed, and same difference between cooler-tem...

Several points: 1) the HR-01's fairly large size combined with low airflow impedance makes it really efficient with very low airflow. 2) However, with very low airflow, the HR-01 has fairly modest cooling capability relative to today's hottest processors. This cooler with low speed Nexus does well ...

Have you considered undervolting by the way? Getting the voltage down to arodun 1V should get the power usage down 10-30 watts I would guess? That might help.

In tother words in the 40-50 range of temps. Yes, if your calculation is correct, then at 12V the same fan should be 40C over ambient, so 40C+26C=66C when it fact it is 76C. Now it was originally at 7V, and with 24C ambient it should have been 43C+24C=67C, but in fact it was 80C. So 10C hotter than...

It was not said what the ambient temperature was when 76C was recorded. If we assume that it was 26C, then 76C-26C=50C over ambient. Look up the SPCR revie...
