The poor quality of stock TRUEs is exposed yet again. In the end, the stock Achilles v.2 still didn't win against a lapped and pressure-modded TRUE, but a stock TRUE failed to complete the test, while even the S1283 kept going. I wonder how the Achilles would do with a pressure mod?
Also worth noting is how cooler performance changed with higher voltages and overclocks; it shows what a difference extra heatpipes make. At lower temps, extra heatpipes do not help with performance. This might explain why you see S1283s beating TRUEs in some tests but not in others with extreme temps.
It's still clear that HDT is superior to non-HDT, however, they need to find some way of squeezing more heatpipes into the design, and adding more surface pressure.
"As if the heat being put out by the Q6600 wasn?t bad enough already, this is where things really start to go crazy. Pushing the CPU up to a stable 3Ghz @ approximately 1.504Vcore, the backplate of the Thermalright Ultra 120 Extreme was dangerously hot to the touch so much that I actually burned myself moving the motherboard back to my workbench. The retail sample I acquired from Alex at Petra?s Tech Shop, shot up right past 85c after several minutes of load testing before the system finally shut itself down. This was most unexpected from a TRUE, being the top tier cooler that it is. However the problems with Thermalright?s manufacturing have plagued the retail Ultra 120 Extreme?s for the past year, from uneven bases to poor mounting systems which are loose to the point where the whole heatsink itself can do a partial turn with ease while mounted. Too my surprise however, all three Xigmatek coolers stayed under the thermal threshold during these tests."
