All fansinks are the same . . . well, all Golden Orbs are the same when they leave the Thermaltake plant: burningissues has just repeatedly tested two of them over twelve weeks on different CPU's at
different vcores & they are EXACTLY the same. What's more, we've checked these tests against some carried out by a public-spirited fansink maker/designer who uses all sorts of expensive precision measuring-widgets; & his & our results agree within a couple of %
All of us know that if one of these two GOrbs goes onto a friend's machine they'll see different temperature readouts from their copy of MotherBoardMonitor;
but the basic efficiency of the fansink - it's ability to wick heat from a CPU & radiate it into the airflow in a computer-case - has stayed, of course, EXACTLY the same.
This efficiency can be given a numerical value: it's called °C/W "sink-to-air" - °C/W s-a for short. It's the same number if worked out from our test-system, or in any other properly monitored
system anywhere in the world. It's this portable & objective figure that burningissues & the fansink-maker compared.
To find out this efficiency you need a few accurate figures:
1) the CPU type, speed, vcore, & package-temperature
2) the temperature of the air in the computer [or room if you leave the case open]
3) the heatsink grease thermal resistance & thickness.
- you'll also need 90 seconds with a calculator.
What you'll find - if you measure CPU-temperatures through-case - is that the °C/W s-a for all & any GOrb's is 0.490 on a PPGA, 0.515 on a FC-PGA/Duron/TBird. If there's an error due to our
methodology, it'll be towards being too optimistic [too low a figure] - this is because we don't measure the CPU-cap adjacent the core ["tcase"], but right through the CPU-package ["bcase"] - just like your mobo-sensor does but a helluva lot more accurately.
We said above: "all fansinks are the same" . . . . . but all fansink tests are not: here's some data from a spreadsheet we prepared after going to Google Advanced Search & punching in:
"Golden Orb" + test : every published GOrb test found with an adequate quantity, if not quality, of information is included in the table below.
