Since most of the heatsinks coming out are designed for higher spec systems, I have forgone the 1000MHz and 1100MHz tests. This will allow us to concentrate on whether or not the sink can perform up to today's standard levels. After all, with the budget systems coming in at 1.2GHz and higher, it's time to set the mark just a bit higher in our heatsink comparisons.
That said, here is the test system that we are working with:
Antec SX1030 Tower Case w/ 170-CFM Airflow
AMD Thunderbird 1000 @ 1333 (AVIA)
256MB Crucial PC133 SDRAM
IBM GXP60 40GB Hard Drive
Prolink XX-Player GeForce3
Arctic Silver II
The core voltage of the processor is set to 1.8v, and memory is set to the standard 3.3v. Ambient air temperature was sitting at 21C and didn't fluctuate during testing. Processor speed was firmly at 1333MHz, which puts out about 73.6 watts of heat.
Testing will consist of measuring the temperatures at idle, after a Quake III Arena Deathmatch, and after a continuous looping of 3dMark2001. These are the main types of stresses that today's systems face, so we'll concentrate on them.
So how did the Alpha perform under pressure? Let's find outů
OK, let's see what we have here. A heatsink that performs at nearly the same level as the Gladiator, but doesn't knock the paint off the walls because of the high noise levels. I think that may be a satisfactory tradeoff for having to remove the motherboard to install it.
