Deepcool G15 (Silicone-Based/Non-Conductive/5.2 W/mK/Overclocking-Focused Paste) Review
Deepcool G15 is a silicone-based, nanotechnology-infused thermal paste marketed specifically at the overclocking community, officially rated at 5.2 W/mK with a 1.5g grease weight.
5.2 W/mK puts G15 comfortably ahead of Deepcool's own Z-series compounds (Z3 and Z3 PRO/Z5 PRO all officially rate lower), while still trailing the DS7/DS9 specialist lines. Deepcool explicitly targets this at overclockers and extreme gamers rather than casual builders, and the organosilicon, nanotech-processed formula is meant to stay stable and non-volatile rather than drying out under sustained heat cycling. The -50 to 240 C range is wide enough for most air and liquid cooling setups, and it's eco-friendly, insulating and anti-corrosive by Deepcool's own description.
Thermal Performance and Conductivity
Officially rated at 5.2 W/(m·K), ahead of the Z-series pastes in this catalog and Deepcool's own product line, positioning G15 as a mid-tier overclocking compound.
Compound Type and Composition
Deepcool describes G15 as an organosilicon (silicone-based) material processed with nanotechnology for stability and smooth application.
Application and Consistency
Ships in syringe packaging for easy application and storage; Deepcool markets the nanotechnology formula as stable and non-volatile over time.
Electrical Safety
Non-conductive and, per Deepcool, strongly corrosion resistant.
Comparison to Sibling Products
G40 (also in this catalog) shares the identical 5.2 W/mK rating and formula, just in a larger 4g tube. Choose G15 for a single install, G40 if you want more paste per purchase.

Best for
- Overclockers and enthusiasts wanting a documented mid-tier conductivity figure
- Single-application installs where 1.5g is enough
Not for
- Buyers who need DS7/DS9-tier top-end conductivity
- Bulk buyers wanting more grease per tube (see G40 instead)
FAQs
What are the key specifications of the Deepcool G15 (Silicone-Based/Non-Conductive/5.2 W/mK/Overclocking-Focused Paste)?
The Deepcool G15 (Silicone-Based/Non-Conductive/5.2 W/mK/Overclocking-Focused Paste) is a thermal paste from Deepcool. Key specs: Form Paste, Material Silicone-Based (Deepcool describes it as an "organosilicon material" using nanotechnology), Thermal Conductivity 5.2, Electrical Conductivity Non-Conductive, Recommended Use High-end CPU/GPU (marketed for the overclocking community and extreme gamers).
Will the Deepcool G15 (Silicone-Based/Non-Conductive/5.2 W/mK/Overclocking-Focused Paste) work with my current setup?
The Deepcool G15 (Silicone-Based/Non-Conductive/5.2 W/mK/Overclocking-Focused Paste) lists Thermal Conductivity is 5.2. Check that against the hardware you already own before buying, since this is the field that most often decides whether a part fits.
Who is the Deepcool G15 (Silicone-Based/Non-Conductive/5.2 W/mK/Overclocking-Focused Paste) best suited to?
It suits overclockers and enthusiasts wanting a documented mid-tier conductivity figure, single-application installs where 1.5g is enough.
What are the drawbacks of the Deepcool G15 (Silicone-Based/Non-Conductive/5.2 W/mK/Overclocking-Focused Paste)?
It is a poor fit for buyers who need ds7/ds9-tier top-end conductivity, bulk buyers wanting more grease per tube (see g40 instead).
