Setup & Results

Many people use Prime95 to do stress load or burn-in the CPU but we decided to use Over Clocking Checking Tool (OCCT) for this testing, as we feel that this software would generate a maximum amount of heat (more so than Prime95), and we want to push the GTZ performance envelope.

The block was installed with Arctic MX-2 thermal paste in an enclosed test bed rig and the ambient air temperature was maintained at 21?C.? According to Arctic Cooling, there is no curing time required for the MX-2 so we ran the benchmark right after the block installed for exactly 1 hour and 5 minutes (the extra five minutes is to compensate for the idling time at the 55 minute mark when OCCT stops utilizing the CPU). This way we will have exactly 60 minutes of 100% load to the CPU only, no RAM test enabled. Then we let the system idle for 30 minutes after stopping and temperatures were checked. Then the system was left idling for an additional 30 minutes prior to starting another test.?All radiator fans were kept at 800 RPM during testing. Everest software was use to monitor and log all the temperatures.

The test system setup is outlined below:

Intel Core2Quad Q6600 @ 3.6 Ghz, vCore 1.425v, NB 1.39v
ASUS Maximus Formula SE X38 chipset

8Gb OCZ PC8500 Reaper Edition
Graphics Card:
EVGA 8800GTS 640Mb
Hard Disk Drive:
Western Digital 500GB – RAID 0
Optical Drive:
Plextor PX760A
Silverstone TJ09 (mid instake fan removed)
Watercooling System:
Swiftech MCP655 pump, MCR320 & MCR120 (in series), Micro-Reservoir, 3/8" Tubing, integrated ASUS Fusion block/heatpipe
Operating System:
Window Vista Premium 64-bit

Below is comparison of the idle and load temperatures of the GTX vs GTZ:

Below is the bar graph that displays the final results of the GTX vs GTZ:

As you can see, the GTZ has an average lower temperature of 5?C at idle and 3?C lower at load than the previous model GTX.
The GTZ’s impingement pin matrix helps to cool down the CPU more quickly than the GTX pin matrix. Even the Northbridge in the loop benefited as well, dropping an average of 6?C.
This is simply an amazing result across the board. The GTZ is far more efficient than Swiftech’s previous flagship block, and has produced some great temperatures here.
