Overall, X2 did an exceptional job at constructing the Eclipse IV. We really appreciated the 12 heat pipes and unique orientation of the twin heatsinks. There are a couple things that need to be addressed with the cooler before we begin. While Spire was going into the correct direction of shortening fan cables, I found it more of a hassle and impossible to connect cables together after the fans were mounted. I think they could also come up with a different mounting procedure altogether as it was also difficult to hold the cooler in place while securing the center bracket.
When I first received the X2 Eclipse IV, it had me thinking I may want to send this to someone else, because I doubted its capabilities of handling a power hungry CPU such as the FX-9370. I would have never considered overclocking a chip that much with only an air cooler, but it really surprised me. Everything it did suggests it can handle it. While the Eclipse isn’t the biggest air cooler in the lineup today, I would say it performed exceptionally well, especially against the more beefy coolers while overclocking.
At the time of the review, the X2 Eclipse IV is available at coolerguys.com for $59.95 USD plus shipping with a 2 year manufacturer’s warranty. For most, this is about the normal price range for air coolers in its performance range and in my opinion is well worth it. PureOverclock easily awards the X2 Spire Eclipse IV with the PureOverclock Great Hardware Award.
