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.
Thor's Hammer did an impressive job of cooling our T.E.C.C., especially considering I used some three dollar fans to get my results. As I explained earlier, they should give you a good idea of what an average fan will produce for you. Xigmatek's Thor's Hammer idled at a cool 52.3° Celsius in the single fan configuration and with the dual fan set-up it was 0.6° cooler at 51.7° Celsius.
Moving over to the load testing, you can see both the one fan and the two fan set-ups report only a 5° overall increase of temperatures. Testing results for the single fan was 57.3° Celsius, while the dual fan set-up reads at 56.6° Celsius. Considering there are much better fans available to the consumer than my 88CFM Yate Loons, this should give a good perspective on what to expect.
The sound pressure level testing done on the Thor's Hammer is no way reflective of the cooler itself, as Xigmatek ships this cooler without an accompanying fan. These were just the results I got from the fans used. Idle noise started with one fan at 55 dB and it gets a bit of a bump with dual fans running to 59 dB.
Load testing wasn't too great for these fans. The single fan reported in at 66dB and the dual configuration was a bit louder at 68dB. Again, your results will vary depending on what fan or fans you choose to use with Xigmateks Thor's Hammer.
