Thermal pastes have always been something that could give you an advantage and better performance over the stock paste.

We have seen many pastes, ceramique/silver/diamond/metal based that promise better temps!

So...what they really do?

  • For testing the pastes, I have used a 230w peltier in order to have a high thermal load and make the differences bigger and noticeable.
  • Room temp was at 24 dergees always
  • Coolermaster V8 with Nanoxia 12cm fan@1800rpm was used
  • Temps were taken from a copper plate between peltier and cooler(simulating a typical cpu heatspreader)
  • Temps were taken with a digital IR thermometer for accuracy
  • Before every new paste everything was cleaned with alcohol
  • For every paste I have done the break-in time as was specified by the manufacturer
  • Each reading was taken 5 times to ensure accuracy, if anything abnormal was noticed the test was done from the beginning. 



The thermal pastes used in the test are:

  1. Coollaboratory Liquid Pro
  2. IC Diamond
  3. Noctua NT-H1
  4. OCZ Freezer Extreme
  5. CoolerMaster Thermalfusion 400

  22. Cooljag paste
  23. Vantec paste
  24. CoolerMaster Premium grease

The best thermal compound proved to be the Coollaboratory Liquid Pro, followed by IC Diamond and Noctua NT-H1.


Differences are not so noticable because all surfaces were perfectly lapped.Cpu's and heatinks don't have so well lapped contact surfaces, so the real life differences will probably be bigger.This happens because if the surfaces are very well lappe, thermal paste is just to fill tiny gaps, but if the surfaces are rough then paste has to fill much more space, and if it has not good thermal conductivity differences are more noticable. 

The purpose of this round-up was to compare the 44 pastes under the exactly same conditions to find out which one performs better.

In fact the most limiting factor is the cpu and heatsink contact surfaces, and the thermal paste by its own.A well lapped cpu heatspreader and heatsink can help to get better temperatures even and with mid-range thermal pastes.


So...if you want the best out of your cooler, you must choose one of these!

And the awards...!


                                                                 Coollaboratory Liquid Pro

                                                      "For the highest performance and innovation"




                                                                          IC Diamond

                                                         "For high performance and innovation"





                                                                      Noctua NT-H1

                                                       "For performance and quick break-in time"







UPDATE 11/3/2009

A new round-up will follow, only with the 5 top performing pastes using numerous heat loads from 45 to 400 watts.

Stay tuned Wink Wink Unfortunately it is not possible to further test the pastes with higher thermal loads, because even watercooling cannot handle such load.
