To gauge the cooling performance of the Corsair H80, I will be using an Intel i7 920 at both stock and overclocked speeds. For the overclocking portion of the test, the processor will be set at 3.6GHz with the voltage level set to 1.30V. For the idle temperatures all programs will be shut down and the results will be recorded after 20 minutes, and for load temp testing I will be using Prime95. The program will run for 15 minutes before temperatures are gathered with RealTemp. To ensure proper performance between all models, each cooler was tested within on a few hours of each other.
Testing Setup
- Processor : Intel Core i7 920
- Motherboard: MSI X58 Platinum
- Memory:6GB Mushkin Redline DDR3 1600
- Video Card : XFX ATI HD 5870
- Hard Drive : Seagate 7200.11 1.5TB
- Power supply: Enermax Galaxy 1000w
- Operating System : Microsoft Windows 7 Pro
The thermal performance of the Corsair H80 is quite impressive. In both our stock and overclocked testing, the H80 performed better than all of our comparison heatsinks. What really impressed us though was that the H80 was able to maintain a higher degree of thermal performance than the other models even after we increased the CPU voltage to 1.35V.
While our results didn't match up to Corsair's internal testing, which claimed the H80 to be 15% more efficient than the H60, we were still close. With our Intel i7 920 overclocked to 3.6GHz and the voltage increased to 1.30V, our results showed the H80 to be more efficient by roughly 12% when the fans are set to high. When we reduced the fan speed to the minimum setting, this difference dropped to around 8%.
During the testing process we used the Corsair H80 at both low and high RPM settings. While the performance was of course best with the fans speed set to high, the overall acoustics were actually quite loud. A quick reading from our decibel meter showed that at a distance of three feet the fans were producing a noise output 46dBA, which is definitely audible. When the fans were set to low RPM the acoustic levels improved, and our readings at three feet were just 39dBA.

I'be glad to give a report on its use in the real world. My system runs hot when backing up Drive C: (Velociraptor 600GB) using Acronis, which grabs 100% of all eight cores and overheats (65C) roughtly halfway through the backup (65GB) using the stock air cooler.
I'm hoping to get that down a bit with the H80. Looking forward to it! I'm also upping the CPU from the 8120 to the FX-8150, using 4x4GB 1866Hz Corsair Vengeance DDR3 and a GTX580 SC. Object: To get to do quick video rendering work, along with digital music in the studio here. Adobe.com certifies the GTX580 as being able to be "borrowed" during rendering operations for Prem-Pro.
If anyone wants to hear how it all turns out, drop a pm!

If this thing performs like i think it will. I will have a brand new Noctua nh-14 to sell. lol.
We would like to review on though.
The software is not available yet, but it does allow the user to control the fan speed.
