I purchased this to use in a very height restricted mini-itx desktop case. It does the job. ### ⭐⭐ Dynatron A18 1U Active PWM Blower *by K***R on December 13, 2025* The Dynatron A18 1U Active PWM CPU Blower Fan and Heat sink Under perform, Doesn't Cool the Ryzen 9 7900X CPU. The Fan is loud and gets louder when the Fan Speed Up. ### ⭐⭐⭐⭐ It Worked With Some Modifications *by C***4 on February 5, 2026* Some positives: 1. It fits in a 1u case comfortably. 2. It keeps a Ryzen 2400ge adequately cooled. Some negatives: 1. It is loud, if this is a concern you have, consider different options to lower the fan speed such as BIOS or a fan speed controller. This is probably going to be your best option for a 1u case. 2. The heat sink may interfere with other components on the motherboard and may require some modification. I ended up using a dremel to notch the heat sink in two spots to get it to fit properly in the motherboard without interfering with any other components. If you do go this route, please be sure to blow out the copper dust and pick out the metal burs in the heat sink after notching it so you dont blow copper dust and burs all over your motherboard when you turn it in. --- ## 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.ph/products/73638822-dynatron-a18-1u-active-pwm-blower-with-copper-fins-active](https://www.desertcart.ph/products/73638822-dynatron-a18-1u-active-pwm-blower-with-copper-fins-active) --- *Product available on Desertcart Philippines* *Store origin: PH* *Last updated: 2026-09-04*
