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.
Vantec has been putting out a very good heatsink lately, so I'm looking forward to seeing what their copper model can really do. So let's find out…
- 1000MHz (57.4 Watts)
The Vantec unit is performing just as it should be. No stellar leaps, but no high temperatures either. It certainly looks like the copper heatsink is doing exactly what it should be doing…keeping the processor COOL.
But let's juice it up just a little and see what happens…
- 1100MHz (62.2 Watts)
Even though the Vantec copper is trailing the other copper units, the difference isn't very great. But the benefit of using a copper heatsink should be apparent as they are getting consistently better temperatures than the aluminum models.
So lets bump the speed up even more to see how it can handle the stress of a 33% overclock…
- 1333MHz (73.6 Watts)
Well, the Vantec copper unit was on par with the other copper sinks, but it didn't manage to shatter any records. Still, the overall cooling capabilities of the sink will allow you to use it with any of the available Thunderbird processors out there.
