Battle of the Goop - Thermal Paste Comparison

Testing & Conclusion

Testing

Applying Thermal Compound can be a hit and miss affair, so to ensure our test results were as accurate as possible each of the compounds was applied several times. The application providing the lowest temperature was then allowed to 'settle in' for 24 hours before any measurements were taken.

The 'settle in' period consisted of the test machine being placed under heavy load for a total of 12 hours, and then left in an idle state for a further 12 hours.

Load temperatures were taken after 1hr of Prime95 with "In-Place large FFT's".

Test machine specification:

Intel P4 630 'Prescott' @ 4.2ghz (1.6v Vcore)
Swiftech Apogee Water Block
Laing D5 Pump
Black Ice Xtreme II Radiator
4x 72cfm Fans on Radiator

Idle Temperature Load Temperature

The clear winner in these tests was the Coollaboratory Liquid Pro. Being a full 6°C lower than Arctic Silver 5 when placed under load, this truly does go to show that there are major benefits to be had by switching your thermal compound.

Arctic Silver 5 took second position throughout, being threatened only by the Shin-Etsu X23-7762 compound which equalled its temperatures at idle, and was within 1°C of the AS5 under load.

In last place was the Shin-Etsu G751, which despite producing fairly reasonable results, was still almost a full 10°C above the Coollaboratory Liquid Pro in the load tests.


Conclusion

For me the competition really came down to two candidates, the Arctic Silver 5 and the Coollaboratory Liquid Pro. The Arctic Silver produced some good results and was by far the easiest to spread out of all the compounds, however its performance was somewhat overshadowed by the excellent results from the Coollaboratory Liquid Pro.

It is also worth mentioning that many people find Shin-Etsu to produce better results than AS5 when used on bare core CPU's (Such as the Athlon XP), or uneven surfaces such as North/SouthBridge's.

A poor attempt at that.

Me either, but i an't sorry about it.

If AMD want to sell them then they need to cut the price by £70-100. Not stick a differeent hs on.Quote
