New Dual-Tower cooler from SilentiumPC – Grandis 3 in test

The Grandis 3 replaces the predecessor model from SilentiumPC as the flagship. Briefly summarized there is a massive heatsink, a 120 mm and a 140 mm fan and an appealing look at a low price around 50 €. Beside the standard model this one is also available as ARGB version. But can the Grandis 3 also prove in the test that it can keep up with the strong competition? To evaluate this, we have tested the non-RGB version for you.

Scope of delivery and workmanship

In addition to the cooling tower and the two fans, the kit contains the usual mounting material, heat-conducting paste, a PWM splitter and the mounting instructions. The mounting of the fans to the cooling tower is realized by mounting brackets, there is no decoupling of the fans. However, this did not become noticeable later, there was no interference noise due to vibrations.

The heatpipes are covered by plastic caps, the uppermost cooling fins are coloured black. Additionally the ends of the cooling fins are serrated, which results in a nice look. Regarding the processing of the cooling fins there were no defects – no bent cooling fins, no irregular spacing.

When assembled, the fan protrudes slightly above the cooling towers in the middle – this provides a slight draft in the direction of the voltage converters. An additional voltage transformer cooling is quite useful and should not be underestimated.

The only negative points that stand out were during the installation of the cooler. On my test specimen, the fan could not be inserted from above, but unfortunately only from the side. Optically I could not find a reason – this makes the later assembly more difficult. Additionally the spacers to the mounting rail did not hold in the AMD backplate. You had to fix them by yourself until they were screwed together.
