Overview

Arctic Silver 5 has been a staple thermal compound for PC enthusiasts for over two decades. This 3.5g syringe version contains a high-density blend of micronized silver and thermally conductive ceramic particles, with over 88% of its weight being conductive materials. According to manufacturer data, it can lower full-load CPU core temperatures by 3–12°C compared to standard thermal pads or compounds. What sets Arctic Silver 5 apart from ordinary silicone greases is its long-term stability: it resists separation, migration, and pump-out effect even after years of thermal cycling. The 3.5g syringe is generously sized, covering approximately 16 square inches at a thickness of 0.003 inches — enough for 15–25 small CPU cores, 6–10 large cores, or 2–5 heat plates. In the thermal grease market, Arctic Silver 5 sits as one of the most well-known and trusted products in the entry-to-mid-range segment. While it commands a premium price, its reputation for reliability makes it a safe choice for first-time builders and seasoned enthusiasts alike.

Compatibility Guide

Arctic Silver 5 is a universal thermal interface material compatible with all CPU socket types, including Intel LGA1200/1700/1851, AMD AM4/AM5/TR4, and GPU dies. No special compatibility requirements exist — it works with any cooler that has a flat base plate. Application is straightforward: place a rice-grain-sized dot (approximately 0.1g) in the center of the CPU IHS, then mount the cooler evenly. The included syringe allows direct application without tools. While the compound is electrically non-conductive, it contains silver particles and should be kept away from exposed circuits to avoid potential shorts.

Product Info

Arctic Silver 5 was first introduced in the early 2000s and remains in active production. It is widely available through major online retailers. On , the 3.5g syringe is priced at approximately ¥10,258, which places it in the premium tier for thermal paste. Key physical specs: dimensions 40 × 30 × 10 mm, weight 0.09 kg, containing micronized silver, sub-micron zinc oxide, aluminum oxide, and boron nitride particles. The recommended application thickness is 0.003 inches (0.076 mm), and the syringe can cover roughly 16 square inches. Thermal conductivity values are not officially disclosed, but third-party tests consistently show significant temperature improvements.

Best Use Cases

First-time PC builder changing thermal paste for the first time — Arctic Silver 5 is forgiving to apply and hard to mess up. The thick consistency spreads well and doesn't run. Not ideal for someone on a very tight budget who just wants the cheapest option. User refreshing a PC that has been running for years — The compound's resistance to drying and pump-out makes it perfect for long-term installations. If you plan to keep the same system for 3–5 years without repasting, this is a strong choice. Enthusiast dabbling in mild overclocking — Lower core temperatures provide more headroom for stable overclocks. However, for extreme sub-ambient cooling, a liquid metal paste would be more appropriate. Silence-seeker trying to reduce fan noise — Cooler CPU temperatures allow lower fan speeds. But if your cooler is undersized, paste alone won't fix the noise issue.

Things to Consider

Arctic Silver 5 does not have the highest absolute thermal conductivity among modern pastes. Diamond-infused or carbon-based pastes can outperform it on paper. Also, despite being non-conductive, the silver content means a stray smear across motherboard pins can still cause problems — careful application is required. Price is a notable factor: at ~¥10,258 for 3.5g, it costs significantly more than basic silicone greases. You're paying for longevity and consistency, not raw performance per gram. If you repaste every year, cheaper options make more sense. Be aware that the compound can arrive slightly solidified in cold weather. Knead the syringe for a minute before use to ensure even consistency. Also, if your cooler mount pressure is very light (e.g., some GPU coolers), use slightly less paste than usual to avoid hydraulic cushioning that reduces contact. ## FAQ
Q: How often should I replace Arctic Silver 5? A: Typically every 2–3 years is recommended. If you notice CPU temperatures rising 5°C or more under load, or system instability, it's time for a change. Arctic Silver 5 lasts longer than many alternatives, but after 3 years degradation may start. Q: Can I use this on a GPU? A: Yes. For GPU dies, apply a slightly smaller amount than for CPUs because the die is smaller and cooler mounting pressure may be lower. It works great for repasting gfx cards. Q: How many applications does 3.5g provide? A: For typical desktop CPUs (Intel LGA1200/1700, AMD AM4), expect 15–25 applications. For large HEDT processors (Threadripper), about 6–10. One syringe will probably outlast your interest in repasting.
