PTM 7950 is probably the best thermal paste you can buy for a laptop right now. I tested it on my Dell G15,it performs admirably and beat the OEM thermal paste used by Dell in my laptop I would highly recommend this PTM7950 thermal pad to anyone who has an overheating laptop **Q: how's the performance?** A: So far seems to be extremely good. Applied this on a Dell XPS15 9570 laptop, the temps have dropped by around 15 degrees. and this product seems to stay within good price! If you need moderate price thermal conductivity thermal pads, I would recommend this thermal pad! Worth a try **Q: Hey, how is this comparable to "Honeywell" 7950 phase change thermal pad. Is this the same thing?** A: I've installed it in a very hot trashcan Mac Pro in both GPUS and CPU and the temperatures have dropped by around 15 degrees. to the point that I can overclock the GPUs safely in windows. I'd say the performance is incredible but I can't say for certain if it's as good a one sold by the name brand Honeywell. but from reviews I've seen on YouTube and other commenters on other websites seems like these are also Honeywell, just sold in bulk to resellers. **Q: Just recently replaced my paste with these pads on my laptop.Should i be concern if i made a cutof the pads thats bigger than the cpu die?** A: No. It's not electricaly conductive. It's safe ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by A***ー on February 24, 2026* よく冷えます。 ### ⭐⭐⭐⭐⭐ Review *by N***N on August 25, 2025* 事前情報通り、やはり貼り付けについては苦心しました。 CPUに直で貼るよりも、クーラー側に貼る方が作業しやすいのでは ないかと思われます。冷蔵庫で冷やすと剥がしやすく、スマートに 作業できます。 冷却性能については全く不満ありません。 CPU温度をそれとなく終日監視してみましたが、高性能グリスと 比較しても突発的な急上昇を抑える印象で、今のところは個人的に 理想的です。 これは体感の話となりますが、本格運用前にCPUベンチで70～80℃ 位まで上げて10分間保つなどの馴染ませをすると、より性能が安定 した？ 気がします。（相変化素材の特性を鑑みて……） CPU：14600K クーラー：be quiet！ DARK ROCK ELITE ### ⭐⭐⭐⭐ Review *by ス***ク on January 3, 2026* 半信半疑で賛否両論だったので不安でしたが、噂通り冷蔵庫で冷やしてから手早く作業しました。そんなに不器用でなければ綺麗に仕上がると思います。効果としては平均値が-10度出てました。塗替えついでに中の掃除もしちゃいましょう！ ## Frequently Bought Together - PTM7950 40x80x0.25mm Phase Change GPU Thermal Pad, JOYJOM High Conductive Silicone Grease 8.5W/mK CPU Thermal Paste for PS5 Steam Deck CPU GPU SSD M.2 Laptop - UPSIREN Ultra 16.8w/mk Thermal Putty for VGA GPU IC Processor Rapid Cooling Thermal Pad Replacement Heat Blocking Putty (20g) - 4 Pack 13W/m.K Thermal Pads, 100 x 100mm 0.5mm+1mm+1.5mm+2mm Silicone Cooling Pad Non Conductive Heat Resistance Extreme Odyssey Cover with Dual Self-Adhesive Films for PC Laptop PS4 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/727080803-ptm7950-40x80x0-25mm-phase-change-gpu-thermal-pad-joyjom-high](https://www.desertcart.us/products/727080803-ptm7950-40x80x0-25mm-phase-change-gpu-thermal-pad-joyjom-high) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-04-26*
