Coolink GFXChilla

Testing Methodology

Testing Methodology
 
In order to test the cooling performance of the Coolink GFXCHilla I have decided to compare it against a couple of other heatsinks. I have chosen to compare it to the 'Zalman-esque' Palit heatsink for their NVIDIA 8600GT cards, as well as an Thermalright V2 heatsink. I have taken the liberty of including some gratuitous pics for those interested.

In preparing the test setup for this review I have tried to keep the fan used on the Thermalright V2 heatsink as close to those on the Coolink GFXChilla as possible. I chose to use a Scythe Minebea (3110KL-04W-B19-EB1) 80mm cooling fan. The test setup used has been included below:
  
Intel Q6600 G0 Processor with Intel reference heatsink
ASUS P5B Deluxe WiFi-App Motherboard
OCZ FlexXLC PC2-6400 DDR2 RAM
Palit 8600GT Graphics card
Seagate SATA II 80GB HDD
Thermaltake XASER VI Chassis
Palit 8600GT Heatsink
Thermalright V2 Heatsink

During the testing process all heatsinks received a fresh application of Noctua NH-1 thermal compound and to ensure uniformity of the test results, 3 installs were conducted for each heatsink. After each install the Palit 8600GT graphics card was allowed to idle for 30 minutes to acclimatise, upon which, the temperature was noted using RivaTuner 2.08
 
Graphic load was obtained by using RTHDRIBL for a period of 30 minutes at a resolution of 1024 x 768. Again RivaTuner was used to record the resultant temperature and an average obtained.
 
Ambient temperatures at the time of testing were between 27.5 and 27.9 degree Celcius and case temperatures were between 30.5 and 31.1 degree Celcius respectively.
