GC-3 Extreme Performance Thermal Compound

Gelid GC-Extreme thermal compound is the ultimate in heat conductivity and makes the GC-Extreme the leader in the thermal compounds market.


  1. Ultimate Heat Conductivity
  2. Non-Electrical Conductive
  3. Non-Corrosive, Non-Curing and Non-Toxic
  4. No Bleeding and user friendly
  5. GELID Applicator Supplied

Created for Extreme users, the GC-Extreme thermal compound achieves the best heat conductivity possible between your CPU, VGA or even Chipset to your cooler as the GC-Extreme has a more fluid-like consistency than most other thermal pastes. It’s low viscosity allows it to be spread more easily and thinly for optimal efficiency.

The product comes in two varieties. If the GC-Extreme thermal paste is required for many applications then a 10g tube is available.

Where only a few uses are required a smaller, 3.5g tube would be a more suitable option.

A GELID applicator is supplied which enables an easier, cleaner application of the thermal compound on the processor.



    GC-Extreme is the best thermal paste in our round-up, maintaining a slim lead over the runner-up as long as you’re using a heat sink with high mounting pressure. If this compound was a little softer, it’d be even more ideal and wouldn’t require warming before application. Heating it up a bit does pay off though, and we recommend it for overclockers and enthusiasts.


    I am impressed to say the least with GELID’s latest submission of GC-Extreme thermal compound. Not only does it beat the GC-2, which I thought was a great compound already, but handles the competition very easily. Considering the “industry standard” to be very similar to the results achieved with AS-5, the GC-Extreme is well above standard.


    GELID Solutions have shown us that thermal paste makes a big difference when cooling down a processor with their new, high performance GC-Extreme compound. Taking a massive 18 degrees Celsius off the normal paste that comes with your Intel processor, and outperforming all of its competition, the GC-Extreme is what you’re looking for if you want the highest performing grease in the market.

    Because of its fantastic properties and its price isn’t too bad, I’m going to give this five out of five stars.

Definitely a must!


Applied to a CPU heatsink alu side surface by spreading with a coffee filter lint free paper with one finger to make it as thin as possible, result is 6 to 7 Degrees lower with a Core2Quad LG 775 socket! My Acer Aspire X3810 miniDesktop is very heat producing; no other solution can solve this issue, after a Noctua NF-A8 fan replacement for my CPU heatsink from this shop, of course! Now, this PC unit is one of the best of its own.



Superb performance thermal paste, easy to use, relatively cheap and very effective.

True Performance


The cutting-edge thermal compound… Highly recommended. Very pleased!
