Thermalright Ultra Extreme Copper CPU Cooler Review

Did you think that you already owned the biggest baddest air cooler in the world? Well you are wrong. Soon a few thousand of you will get the ability to join the Ultra Extreme Copper Club. Size does matter, and even more so, what you're made of.

Results: Temperatures

For our stock testing our QX9650 will be kept at 3.0GHz with a minimal 1.25v. For overclocked CPU testing we will be running our QX9650 at 3.8GHz with 1.4625v. Idle temperatures will be recorded after a fifteen minute period of inactivity. Any fluctuation during the last sixty seconds will reset the timer for an additional five minutes. Load temperatures will be recorded after a fifteen minute period of 100% load. To obtain this load we will be using Prime95 v25.3. Any fluctuation during the last sixty seconds will reset the timer for an additional five minutes.

One thing that any potential customer should know is that Thermalright does not supply a fan with its coolers. The temperatures below were obtained using a Thermaltake 120mm Thunderblade. It was retrofitted onto the other units in our comparison so we have an apples-to-apples testing scenario. Obviously using a different fan could net your better or worse results.

The following scores are normalized to the ambient temperature. This will show you visually the rise above ambient temperature as well as the overall temperature.

At stock settings the TRUE Copper takes the top spot even if only by a bit more than one degree. It seems, at least at stock settings, the only competition for the TRUE is the TRUE Copper.

With heat in ample supply here the story doesnآ’t change. The TRUE Copper continues to show off the power of its all copper design. I would dare say that at this point we are running into diminishing returns. That is, if you want better cooling you would need to add much louder fans or many more heat pipes which becomes impractical. This is also a testament to the efficient design Thermalright has created in the TRUE and TRUE Copper.

With heat sink combos that come with a fan we make it a point to test the decibel level generated by the fan. This gives you another tool in your buying arsenal. In the case of the TRUE and TRUE Copper there is no included fan and so it is up to you to select a fan that suits your specific needs.
