Meet the Competitors
For today’s comparison testing I’ve received a list of six competitors and added one myself. Three of the greases came from CaseKing.de, a big thanks for that. Fabacom.nl supplied the Thercool-ICE35 and another was supplied by TIM Consultants, namely their Quantum grease. The sixth I’ve added myself, it’s the ever popular Arctic Silver 5.
First I’ll introduce each of these puppies, then give a short product price and availability overview.
Arctic Cooling MX-4 (MX-4)
“The ARCTIC MX-4 is a new thermal compound that guarantees exceptional heat dissipation from components and maintains the needed stability to push your computer system to its maximum. The ARCTIC MX-4 continues to be overclocker’s ultimate choice when choosing thermal compound.”
The MX-4 comes with a useful little plastic shovel to help you even out the grease on the surface before applying the heatsink.
Minimum price: €4,90
Average price: €8,50
Average price per gram: €2,13
Arctic Silver 5 (AS-5)
“With its unique high-density filling of micronized silver and enhanced thermally conductive ceramic particles, Arctic Silver 5 provides a new level of performance and stability. Available at Arctic Silver resellers worldwide. Arctic Silver 5 is the reference premium thermal compound. Arctic Silver 5 is optimized for a wide range of bond lines between modern high-power CPUs and high performance heatsinks or water-cooling solutions.”
Brought in from my own stash, this AS-5 has helped me out for years. This is an excellent opportunity to see if this old-timer still can compete with the newest materials on the market.
Minimum price: €4,90
Average price: €8,90
Average price per gram: €2,54
Prolimatech PK-1 (PK-1)
“Over the years, Prolimatech PK-1 has become one of the hardware testers’ favorite. It is not hard to see why. PK-1 is a premium grade of thermal compound that is easy to spread and is reliable throughout the year. It will not dry out while continuing to provide good heat transfer from your CPU to your heatsink base. Performance-wise, Pk-1 is a contender for the top spot as it beat other major brands of thermal compound in the market. To maintain top condition, we highly recommend reapplying PK-1 every year.”
Prolimatech supplied me with a review sample in a simple plastic bag. Therefor I can’t say anything special about the retail package, besides the typical information.
Minimum price: €6,65
Average price: €10,10
Average price per gram: €2,02
TherCool ICE-35 (ICE-35)
“Recently developed super conductive thermal grease. TherCool ICE is based on TherCool TSI but with further improved thermal conduction. This is one of the best thermal greases available today. It is such a paste composition which combines the thermal conductive qualities of nano-aluminum nitride and organic siloxane compounds. It gives the grease an excellent thermal conductivity. The thermal conductivity has reached or passed the thermal conductivity of other products available on the market today. (…) It is the best product for the CPU COOLER today”
After some searching I finally found three webshops that sell this product (one Dutch, two British through Heise.de’s price comparison). As it seems from their website, TherCool’s portfolio is limited to this product and three other TIM’s.
Minimum price: €7,94
Average price: €8,68
Average price per gram: €2,48
TIM-Consultants Quantum (Quantum)
I obtained the Quantum from TIM-Consultants because I was roaming the internet and happened to find a reference to this ‘new grease’, so I looked it up. Quantum and it’s predecessor are the only products from TIM-Consultants. Their website is also the only place where one can buy their products, as of the time of writing.
Minimum price: €3.-
Average price: €3.-
Average price per gram: €1,88
XigmaTek PTI-G3606 (PTI)
“PTI-G3606 is Silicon-base thermal grease with excellent heat-conductive filler and effective thermal grease for any heat sink device where efficient cooling is required, such as CPU power transistor, and SCRs to heat sink or chassis. It will not dry out, harden, or melt even after long term exposure to temperatures up to 240”
Minimum price: €4,50
Average price: €7,09
Average price per gram: €2,36
Here’s a quick overview on the average price per gram:
Well available and low priced Prolimatech PK-1 (€2,02), Arctic Cooling MX-4 (€2.13)
Cheapest: TIM-Consultants Quantum (€1,88)
Disregarding performance for now, if you were to be buying parts at a webshop and could get the PK-1 or MX-4 for a reasonable price, there seems no justification yet as why to buy Quantum.
