Spire did a good job improving the TherMax Eclipse CPU cooler. We didn’t compare both versions on the same testbed because since our test with the original TherMax Eclipse we’ve change our testbed, but the comparison we did between the original Spire TherMax Eclipse and top-performance CPU coolers showed that the first version was "weaker" than top-shelf CPU coolers, but now the new TherMax Eclipse II had practically the same performance level of the best CPU coolers we’ve tested.
The TherMax Eclipse II has no PWM fans, but the ones included are strong yet relatively quiet; if you connect them to a fan controller, you will be able to adjust their speeds to your needs: performance, silence, or finding the right balance between both.
The only issue we had with the TherMax Eclipse II was installing it. Due to the position of the thumbnuts, we had to remove our motherboard from the case to install the product.
The Spire TherMax Eclipse II cooler is a real top-notch CPU cooler, so it gets the Hardware Secrets Golden Award.
