IETS300 Cooler Noise Concerns Rise Among Legion Pro 5i Users

IETS300 Cooler Noise Concerns Rise Among Legion Pro 5i Users...

A growing number of Lenovo Legion Pro 5i laptop owners are reporting excessive noise levels when using the popular IETS300 cooling pad. Recent benchmarks shared on Reddit and tech forums show the cooler's fans reaching 50dB under load, sparking debates about its suitability for high-performance gaming laptops.

The issue gained traction after hardware reviewer TechTesters published comparative thermal tests on February 22, 2026. Their data showed the IETS300 effectively reduces CPU temperatures by 12°C on the Legion Pro 5i, but at significantly higher noise levels than competing coolers like the Klim Ultimate.

Multiple users on the Lenovo subreddit have reported the IETS300's 6000RPM turbo mode creates disruptive high-frequency noise. Some claim it overpowers the laptop's own fans during intensive gaming sessions. The cooler currently holds a 4.2/5 average rating on Amazon, with recent reviews increasingly mentioning noise concerns.

IETS representatives responded to inquiries on February 23, stating the product's design prioritizes cooling performance for high-TDP laptops. They noted the Legion Pro 5i's 140W RTX 4070 configuration requires aggressive cooling, but acknowledged noise sensitivity varies by user.

Professional esports players have mixed reactions. Some prioritize the thermal benefits for competitive gaming, while streamers report audio interference during live broadcasts. The discussion has led some Legion owners to explore alternative cooling solutions or manual fan curve adjustments.

Retailers including Best Buy and Newegg confirm steady IETS300 sales despite the noise reports. Industry analysts suggest the controversy highlights growing consumer awareness of acoustic performance in gaming peripherals. Further testing from independent reviewers is expected this week.
