Testing/Conclusion

he Ultra-X was installed in my Intel test rig and will be compared to the stock Intel heatsink. I will be testing the two heatsinks at both default and overclocked speeds. The test system consists of the following hardware:

Intel Core 2 Duo E6600
EVGA 680i SLI Motherboard
Two 8800 GTX cards in SLI configuration
2 Gb Corsair XMS PC2-6400 Memory
74 Gb Western Digital Raptor 10k RPM HDD
OCZ ProXStream 1000w Power Supply
Lite-On Optical Drive
Two 120mm fans (one intake, one exhaust)


All temperatures were obtained using NVIDIA Monitor. Idle temperatures were taken after 20 minutes of no system activity. Load temperatures were taken after 20 minutes of running Prime 95 (one instance per core). An overclock of 3.2 GHz was obtained using a core voltage of 1.40v. An overclock of 3.5 GHz was obtained using a core voltage of 1.56v. A constant room temperature of 26 C was maintained throughout testing. Do note that these temperature results are specific to this exact system configuration, etc... your results may vary slightly.



I know it is a lot of data to take in at once, but you should be able to make it out pretty easily. At the default clock speed of 2.4 GHz, the Ultra-X on the low fan speed setting outperformed the stock Intel cooler by 8 C at idle and 13 C under load. Bumping the fan up to high gives us an additional 3 C drop at both idle and load. At the overclocked speed of 3.2 GHz, a 13 C drop is seen at idle and a 10 C drop under load with the Ultra-X on low speed. Adjusting to high speed gives us an additional 4 C drop at idle and 6 C drop under load. The max overclock I was able to safely obtain with the Ultra-X and this particular processor was 3.5 GHz @ 1.56v. I did not even attempt this with the stock Intel heatsink, seeing as the max temperature @ 3.2 GHz was 64 C. At 3.5 GHz overclock, the low fan speed setting really isn't an option. The graph reports 68 C under load... but that is where I called it quits. The temperature was still on the rise but I did not want to see it go any higher. With the fan speed on high, I saw a max load temp of 60 C, which is still well within safe operating limits.

Usage, Findings and Conclusion


Well, the results clearly speak for themselves. This heatsink absolutely dominated the stock Intel cooler, but in all fairness, that was expected. I think the market for the Ultra-X is really two-fold. First, this will make a great replacement for someone who simply wants better cooling performance than the stock Intel heatsink. Swap it out for the Ultra-X, set the fan speed to low and forget about it. Right away you are looking at an 8 C temperature drop without any increase in noise. On the other end of the spectrum you have the overclocker. As was the case in our testing here today, we were able to overclock the Core 2 Duo 1,100 MHz, from 2.4 GHz to 3.5 GHz, and still maintain acceptable temperatures... granted, the fan does make a good bit of noise at full throttle. And with the included fan speed controller, you can find a happy medium of overclocking and noise levels that suit your tastes.

The Ultra-X heatsink is the first consumer heatsink from EnzoTech and they really have hit a home run in their first outing. The heatsink uses heatpipe technology and the best of both worlds in regards to construction material; copper to pull the heat away from the core quickly and aluminum to dissipate it. The mirror-like finish on the base of the copper core is perhaps one of the most reflective and smooth I have ever seen. Kudos to EnzoTech for including high quality Arctic Silver 5 thermal grease instead of the run-of-the-mill white goop what we are accustomed to seeing in a heatsink bundle. As of writing, the EnzoTech Ultra-X has an MSRP of $64.99.
