Pastes: be quiet!, Corsair, And Dimastech
be quiet! DC 1
As with a number of other manufacturers, be quiet! merely puts its label on an OEM product. That doesn't necessarily indicate poor quality, so long as the OEM maintains certain standards. And as it turns out, the DC 1 is a solid paste for beginners, ending up in the upper mid-range. Its handling is similar to MX-2, while its performance is a notch better. While we like the product’s quality, we cannot say the same about pricing. Amazon currently offers 3 g for close to $10.

be quiet! (Paste Bundled with be quiet! Heat Sinks)
We're curious about the pastes that heat sink vendors bundle with their coolers. Since cost is always a factor when it comes to value-adds, we want to know whether it makes sense to toss the included stuff and buy aftermarket compound instead.
In this case, we are positively surprised by the freebie. It should be good enough to complement be quiet!'s coolers, which employ high mounting pressure. Under those conditions, the paste comes in a mere 0.6 °C higher than the DC 1, mentioned above.

Corsair (Paste Enclosed With Corsair Coolers)
This time we're looking at thermal paste bundled with Corsair's coolers. The be quiet! and Corsair compounds achieve similar results, though Corsair's paste is perhaps slightly thicker. It's still pretty easy to use though, and we like what we see from our thermal performance results. In this case, it probably wouldn't make much sense to toss the tube and spend good money on something else.

Dimastech HTX-EE
This compound is one of the most difficult to use, and you should only apply it after warming to 110 °F or so. Its performance results are barely better than what you get for free with some heat sinks, though, and so we're left a little disappointed. We're not saying that this is a bad paste, but for the money you can find better options. This stuff is so thick that we were afraid our heat sink's screws would strip their threads as we tightened them.
| Dimastech HTX-EE | |
|---|---|
| Thermal Conductivity | 8.6 W/(m*K) |
| CPU Water Cooling, High Pressure | 33.0 ΔT (22 °C ambient) |
| CPU Air Cooling, High Pressure | 37.1 ΔT (22 °C ambient) |
| CPU Air Cooling, Low Pressure | 37.6 ΔT (22 °C ambient) |
| GPU Cooling | 69.5 ΔT (22 °C ambient) |
| Electrically Conductive | No |
| Viscosity | 7 (1-10, lower numbers mean easier to use) |
| Ease of Use | 2 (1-10, higher numbers mean easier to use) |
| Application Hints | At room temperature, this paste should not be used with the "lentil ball" method. Warm it to 100-120 degrees Fahrenheit in a pot of water, sealed in a water-tight pouch. |
| Price (approximate) | $6 (3.5 grams) |
