Test System & Test Results
TweakTown uses a different method for testing CPU heatsinks which allows for an even playing field across all product tests. We feel that by using the same ambient temperature and strict lab-like testing procedures we are able to accurately compare one product to another. More information on our testing procedure can be found in the T.E.C.C. article here.
Jumping into the top ten in the idle results, the R2 brings some impressive performance over the original version by almost a full two degrees.
Once the testing was run at full steam, the R2 raises up a couple more spots in the loaded results. Getting rid of that thick copper plate was a brilliant idea. It doesn't take a genius to see the improvement from 63.1 degrees to the R2 performance of 59.4°C, it's well worthy of calling the new FLC-3000 a revision and not some smoke and mirrors change in appearance.
I do remember having reservations on the first version of the wording on the package denoting the silence of the cooler. With the R2 the lowered voltage results did produce near silent results.
With the full 12V running through the wires, the amber glowing fan produced the same results I found with the fan almost two years ago. With PWM controlling the fan, it is likely you won't hear this level of noise, but as things warm up inside the case, don't be surprised if the R2 is in fact a bit audible.
