Evercool's original Transformer 4 CPU cooler, with its dual 120mm fans, 8mm copper heatpipes and direct touch design should have been a top performer in the CPU cooling market. It wasn't. The newer Transformer 4 PLUS, with its higher speed PWM fans performs much better and adds socket 1156 support into the mix. In fact, the cooling is quite good and even has the cooling muscle to support some moderate overclocking.
