Testing for this sink followed my normal guidelines so that I can have results that are fairly compared to other heatsinks without bias. Ambient temperature during testing was 21-22C, voltage was set to 1.80 volts and the test system consisted of:
Antec SX1030 Tower Case
AMD Thunderbird 1000 (AVIA)
Abit KT7A-RAID Motherboard
256MB Crucial PC133 CAS2 SDRAM
Arctic Silver Thermal Compound
Creative Annihilator 2 GeForce2 GTS
Temperatures were taken at stock speed, again at 1100MHz, and a final time at 1333MHz. This will give us an idea as to the effectiveness of the sink during both normal, moderate and aggressive clock speeds. The 1333MHz speed testing is a new one that I have incorporated, but with the 1GHz processors and above going to much higher levels, it seemed necessary to see what coolers would be effective when these processors are pushed to these higher limits.
Testing itself included measuring the temperature at idle, after a Quake III Deathmatch battle, and again after a continuous looping of MadOnion's 3dMark2001 Demo. These are the same testing criteria that I have been using in the past, so am maintaining some consistency for the sake of comparison.
So how did the new Hedgehog handle the pressure? I'm glad you asked
- 1000MHz (57.4 Watts)
At standard speeds, the Hedgehog with the Delta fan nearly keeps pace with the infamous Gladiator. Even with the slower Melco fan, it managed to maintain very acceptable temperatures. The highest temperature it got to was just a shade under 41C while under load. While temperatures under 50C are acceptable, if they can be kept under 45C, then you'll be better off in the long run. So lets bump the speed to 1100MHz and see what happens
- 1100MHz (62.2 Watts)
At 1100MHz, we start to see the Hedgehog come into it's own. The copper is starting to show why it's so good as a heatsink material. Whether you use the quiet Melco fan or the monster Delta, the numbers are still showing very favorably for Kanie's newest heatsink. But what about those who want to stress their systems out to the max? Hmmm
- 1333MHz (73.6 Watts)
As I stated before, the testing at 1333MHz is still pretty new. I didn't start using it as a testing criterion until I started reviewing copper heatsinks, so the test results are still pretty skimpy. That will change in the future, of course, but in the meantime it still allows you to see how the Hedgehog heatsink does against the mighty Gladiator. While it doesn't beat it, it remains very close when used in conjunction with the Delta fan option. It also managed to keep temperatures well under 50C with the Melco fan. Not too bad considering that I have seen worse performance with much stronger fans.
