Re: AMD Wraith: Upgraded Stock Cooler

Stock heatsinks similar to the right can be spotted in many lower-end Phenom II and newer products. I say "similar" because there are many slight variants of the fan and heatsink, just like Intel's. http://www.silentpcreview.com/files/images/amd-wraith/00.jpg I find the design pretty good for the si...

Am I the only one here who feels that this case could have easily fitted in a mATX mobo if not for the position of the PCI-E 16x slot on most mATX mobos?

Re: Why the lack of talk on Haswell undervolting

My asrock has voltage override alongside voltage offset. If using override according to cpuz (and bios) it stays at that 0.8V regardless of frequency. I would reckon while VR is integrated much of the control would still remain external, otherwise overclockers would either have a high chance of dest...

Even if you run your computer 24/7, simply using energy-efficient parts or undervolting you will achieve better performance-per-watt than trying to squeeze another 2% out of the PSU's efficiency.

After factoring in some losses that definitely exist, say for example at the transformer (unless 100% efficient transformers exist), to get overall 100% efficiency the other parts have to be 101% efficient. :P

I just realized, Bronze would need 82% efficiency @ 20% load, meaning 110W for a 550W Truepower New. Which makes it more efficient than all the abovementioned PSUs already. But this is not what I'm asking - for example, a PSU was measured to be 80% @ 100W in a 2006 review, another PSU was also measu...

Efficiency measurements, then vs now, comparable?

I would like to ask, the measured efficiencies in long-ago SPCR PSU reviews, can they be used for comparison against those of the more recent reviews, say, those within the past year or two.

What is the best fanless/extreme low airflow cooler now?

Still Scythe Ninja? Or Orochi? Or other tower coolers?

Extreme low airflow meaning no fan mounted on the cooler, some chassis exhaust fan if the CPU's lucky, else only airflow from the PSU's fan.

Ninja's 10 is effectively 12. :lol:

Talk about equilibrium, it may not happen with 10 heatpipes. Ultra 120 has 4 (times 2 = 8) heatpipes while TRUE has 6 (or 12), and we see... 6 degrees difference and higher overclockability.

One problem with blowers is that in computers and many other applications including air-cons and some notebooks, is that the fins are very very small relative to the bearing if you compare it against a axial fan. Hence it has to spin much faster to get the same airflow/pressure. But it's the lack of...
