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.
Since we already know what kind of cooling to expect out of the big brother, I'll be comparing this unit to the 6035D model. This will let us see first hand how well it can keep pace with the cooling capabilities of the larger airflow model.
- 1000MHz (57.4 Watts)
At stock processor speeds, we can see a difference of about 2-4 degrees Celsius between the coolers. Since both use the thin fin design sink and a solid copper base, the reason for the difference is looking to be the fault of the fan. While it's not as cool as the 6035D model, it is still well within the rigid standards that we overclockers look for. So let's see how well it can do when we boost the speed a bit…
- 1100MHz (62.2 Watts)
Again we see the difference in favor of the 6035 model, but it's not as significant as it was before. We'll have to see what happens when we juice it up even more. So let's boost it up to a nice 33% overclock and see where this smaller sink takes us…
- 1333MHz (73.6 Watts)
We're still running about 4 degrees hotter while under load, but again we fall well within an acceptable temperature limit. I don't think that I would go much higher with this sink, but it's not designed for outrageous speeds. It was made to be smaller, lighter and quieter than the 6035D model, and it managed to attain all of these goals.
