Thermal Performance

Thermal Performance scores are derived from the relevant Performance Factor scores. We set this scale with 75% and below as the 0 mark, with each 2.5% increase from 75% in relative performance adding 0.5 to the awarded performance score.

Push Only Thermal Performance – 1.0/5

The Radical 2’s. Reverse Flow and OptiFlow averaged out at 79.35 resulting in a thermal performance score of 1.0.

Push/Pull Thermal Performance – 0.5/5

As we have seen in the data the Radical 2 had extremely poor thermal performance in all the Push/Pull tests, so it was no surprise that a very low score of 0.5 was generated for its Push/Pull score.

Overall Thermal Performance – 0.5/5

Averaging actually brought the Overall Performance Score higher than it would have been without the Reverse flow included. In any case the thermal performance of the Radical 2 remains extremely poor and is the lowest of the entire test group.

Features & Quality – 3/5

The Radical 2 360mm Copper has stylish looks and is well constructed using quality materials. The stainless steel and cooper is striking in appearance and should visually appeal to everybody. The only downside I see is the logos laser engraved on each of the side panels. It is the quality German design and construction with awesome looks which boost the score because the feature set is quite disappointing.

Having just 2 ports (inlet & outlet) the Radical 2 does not offer any opportunity for dedicated fill or drain ports.

The nut insert system used for mounting the rad and fans is the most frustrating system I have come across. I think Aqua Computer should think again about how beneficial they believe this system is. I don’t think it is too much to expect that full sets of hardware be included, so only shipping with one set of mounting hardware is a little disappointing especially when an additional set costs over $12 to purchase.

No protection plates exist between the nuts inserts and tubes, and as 2 tubes are located directly in line with the screw holes care must be taken to avoid damage during installation if different screws are used.

Summary – 1.5/5

The Radical 2 is a very poor performer in the thermal dissipation department, having the worst test results in both Push and Push/Pull.

It has amazing looks and is very well constructed using quality materials but is lacking in features.  The only reason to buy this radiator is that it has the bling and solderless construction of the AMS radiator but at a more affordable price.

I just can’t think of a reason to recommend the Radical 2. Potential buyers should look elsewhere and Aqua Computer might be best advised to reconsider their core design as both their radiators tested were extremely poor performers.

Where to buy: Aqua Computer – $102 USD + shipping from Europe, Performance PCs – $98 + shipping from USA

  1. I have to say i fully agree with you on the mounting solution – it is utterly terrible. It took me and my brother working together to get this to fit in the top of my case (admittedly, it was a tight squeeze which doesn’t help). The fact that it doesn’t come with a full set of the fittings, means mine is supported by 4 on the top, and the other 8 holding fans on the bottom of the rad.
    That aside, the cooling performance of this rad seems to be excellent for me – i have a d5 vario pump (usually running at 1000rpm), fx-8350 with EK waterblock, and this rad (3 x corsair sp120 + 2 x 200mm NZXT case fans. My temperatures are on average, below ambient. While on load, they peak at 35C. When overclocked, i have struggled to get it to go higher than 43C. Although this review suggests that other rads would lower these temps further.
