Prolimatech PK-2 & PK-3 TIM Review

Testing:

To test the Prolimatech TIMs, I will test it twice; both times applying fresh TIM and taking idle and load measurements with Real Temp. If the two test temperatures are far apart, then a third test will be run to ensure accuracy. The final result is the average of the results. Idle temperature is measured at the Windows Desktop 20 minutes idle after start-up. Load temperature is measured during three hour runs of Prime95's Blend stress-test. All testing is done with the processor overclocked to 4.4 GHz for worst case scenario and overclocking results.

Testing Setup:

• Processor: Core i7 2600K @ 4.4 GHz 100 x 44
• CPU Cooling: Corsair H100
• Motherboard: GIGABYTE Z68AP-D3
• Memory: Mushkin 991996 Redline PC3-17000 9-11-10-28 16 GB
• Video Card: XFX HD 7970 Black Edition
• PSU: Mushkin 800W Modular
• Hard Drives: Patriot WildFire 120 GB SSD
• Case: Corsair 600T
• Optical Drive: LG DVD-RW
• OS: Windows 7 Pro 64-Bit SP1

Comparison Thermal Compounds:

• Prolimatech PK-2
• Prolimatech PK-3
• Shin-Etsu G751
• IC Diamond

IC Diamond and MASSCOOL G751 Shin-Etsu are both venerated and regarded as high quality TIMs. The Prolimatech TIMs fit right in between the two at load while coming in slightly behind at idle. Temperature deviation was less than 2 °C between any of the pastes at idle and load. PK-2 and IC Diamond acted very similarly.
