Anything you can do
Last week ASRock, the value motherboard arm of ASUS, contacted HEXUS.channel in order to claim that its P45 motherboard runs cooler than the Gigabyte equivalent and furthermore doesn't require the larger quantities of copper used by Gigabyte.
This missive generated a fair bit of debate, both among HEXUS staff and in the HEXUS.community and prompted a further email from ASRock's technical support department, shown below:
This is Chris, from ASRock technical support department.
Regarding the "2 OZ copper issue", I think we have to explain more detail:
Actually, we did this test purely from technical point of view, so, we tested with the exactly same testing configuration, same CPU, same memory, and same VGA card... as gigabyte tested.
CPU: Intel Core 2 Quad QX 6850
Memory: DDR2 800 512MB x 2
Test tool: Intel P4MaxPower @ 100% Power
ASRock P45 PCB board is using with 1OZ copper, in fact, Intel reference datasheet recommends 1 OZ copper for PCB design as well.
According to our test result, we found that ASRock P45 board's Vcore mosfet temperature (94.3 degrees Celsius) is much cooler than Gigabyte 2 OZ PCB design (125 degrees Celsius). It proves that the H/W design of ASRock P45 boards is much cooler when comparing to others.
Again, we don't want to criticize others, we just want to let users know: Since 1 OZ copper is enough, why 2 OZ? Say "No" to Waste!
