Testing of these heatsinks will be done in the same manner as we have previously used, but with an addition. While the database used for results are primarily done on an older Thoroughbred core processor, the Barton core with its overclockability has become too popular to ignore. So in addition to our normal testing, we'll also be running a 2500+ processor at 2.2GHz to see how it handles a more modern system.
Lets take a look at the test system:
Xoxide modified Lian-Li PC60 Case (supplied by Xoxide)
Soltek SL-75MRN-L Motherboard (supplied by Soltek)
AMD Athlon XP 1800+ Processor
AMD Athlon XP 2500+ Processor @ 2.2GHz
512MB OCZ PC3500 Platinum DDR Memory (supplied by OCZ)
Sapphire Radeon 9800 Pro "Ultimate Edition" (supplied by Sapphire)
Western Digital 80GB Hard Drive
Arctic Silver III
Testing conditions will follow my standard guidelines concerning coolers. Ambient temperature is kept at a regulated 21C and the cooling system will be tested in a closed case. The processor voltage was set to 1.8v and memory was set to 2.8v. Temperatures are measured at idle after 15 minutes of no activity, and then again after a continuous demo looping of 3DMark2001. After these temperatures have been recorded, we'll boost the FSB to 145MHz and run it through the same series of tests. The moderate overclock of only the FSB will allow the processor to do the work and not share the load across the entire system.
For the Barton processor, the testing and settings will be identical to those listed above with one exception, the VCore will be set to 1.65v bringing the maximum heat output to just over 82 watts.
Temperatures - Idle
Though we're just beginning our testing, it is becoming obvious why this new Heat Column technology is showing some promise. Idle temperatures show us that it can even do better than the vaunted Volcano 12 cooler from Thermaltake.
But lets see what happens when we add a little stress to the picture...
Temperatures - 3DMark2001 Demo Loop
It looks as though the more powerful fan used in the V12 unit is coming into play now, but the quiet TTIC cooler still manages to outperform the Vantec unit by 2.5 degrees in each test. Lets toss out the T-Bred and use an overclocked Barton processor now to see what happens.
Temperatures - Barton 2500+ @ 2.2GHz
I'm impressed! We are seeing firsthand what can happen when innovation makes its way to the PC market. The results we have seen are not stellar, but are all accomplished using the factory setup of a single 70mm fan that only puts out 31 decibels of noise. Considering the V12 used in this test quakes at roughly 48 decibels, the end result is a very workable system temperature with a minimal amount of noise.
Oh, and don't forget you can use that same 48 decibel killer fan on this cooler as well with even better cooling results!
