Deepcool DS7 (Non-Conductive/6.9 W/mK/Professional-Grade Paste) Review
Deepcool DS7 is a professional-grade thermal paste that Deepcool itself rates 4 out of 5 stars for performance, officially spec'd at 6.9 W/mK and bundled with a rubber spreader and cleaning wipe.
6.9 W/mK is the highest officially published conductivity figure among the Deepcool products we're adding here, ahead of even EX750 (6.2 W/mK) and DS9 (6.5 W/mK). The catch is the operating range: -20 to 125 C is meaningfully narrower than the -50 to 250 C range most other Deepcool pastes in this catalog carry, so DS7 isn't the pick for extreme sub-ambient cooling setups. For a normal air or liquid-cooled high-end CPU or GPU, though, it's Deepcool's stated best of the DS line below the flagship DS9, and it comes with the applicator and cleaning wipe already in the box.
Thermal Performance and Conductivity
Officially rated at 6.9 W/(m·K), the highest figure among the Deepcool compounds newly added here, and Deepcool grades DS7 itself as a 4-of-5-star "Professional" tier compound.
Compound Type and Composition
Deepcool doesn't publish the specific compound chemistry for DS7, describing it only in terms of thermal conductivity, thermal resistance and insulation performance.
Application and Consistency
Ships with a rubber spreader and cleaning wipe included, so application and cleanup tools come in the box rather than being bought separately.
Electrical Safety
Non-conductive and non-capacitive, per Deepcool, safe for use around sensitive electrical components.
Longevity and Pump-Out Resistance
The -20 to 125 C operating range is the narrowest of the Deepcool pastes newly added here, meaning DS7 is not rated for the extreme sub-ambient or delidded-direct-die temperature swings that the -50 to 250 C compounds in this catalog can handle.
Comparison to Sibling Products
DS7 edges out DS9 on raw conductivity (6.9 vs 6.5 W/mK) but DS9 has the wider temperature range (-40 to 120 C vs DS7's -20 to 125 C) and more grease per applicator (5g vs 2g). Pick DS7 for the higher published conductivity number in a smaller size, DS9 for more paste.
