Filter link: (https://www.desertcart.com/dp/B01KYS02EG?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1) The filters are to prevent dog hair and dust from building-up on the cooling fan blades and other interior components. After covering all the openings of the tower with the filter material, I wanted to monitor the inside temperature of the computer tower since the computer remains on 95% of the time. The filters work great with little to no dust build-up, and the interior tower temperature remains constant, reading between 63 and 71 degrees. The temperature gauge is plugged into a USB port and runs 24/7. Using a piece of rigid foam, the temperature probe is anchored upright in the middle interior space of the tower. Some temperature gauges go dark after a short period of time and require being touched to illuminate the face to read the gauge. The face of the KETOTEK Digital Thermometer is easy to read and remains illuminated 24/7, even when the computer is turned off. I have the gauge set to read Fahrenheit, but the gauge arrives set to read Celsius. At the back of the gauge, there is a small pin that, once removed with tweezers, switches from reading Celsius to reading Fahrenheit. Review: Almost perfect - Surprisingly good. Added this to my PC, good value for money. Easy install. Only suggestion would be for an USB internal 2.0 header interface in lieu of USB-A or 4 PIN molex. A header would be since I usually have one or more available. ## Features - 【USB Power Supply】This digital thermometers is use usb connector as power supply.

Added this to my PC, good value for money. Easy install. Only suggestion would be for an USB internal 2.0 header interface in lieu of USB-A or 4 PIN molex. A header would be since I usually have one or more available. ### ⭐⭐⭐⭐⭐ Great thermometer for fish tanks and very accurate and nice bright display. *by E***S on November 3, 2025* Very fast and accurate for increasing temperature and monitoring variation. It is much slower in settling back to a lower temperature when ramped up by touch and holding the thermocouple sensor with my fingers. The display is bright and easy to read. I am using it for my aquarium tank to check the water temp to the readout from the heater. Someone else posted that the thermocouple interface was rusting but I put Aqueon silicone sealant to prevent that and I think that should fix that issue. I plan to but more for my other tanks. ## Frequently Bought Together - KETOTEK Digital Thermometer Temperature Gauge USB Power Supply with Sensor Probe for Aquarium Vehicle PC Case Incubators Brooders Climb Pet Fahrenheit & Celsius LCD Display - KEYNICE Digital Thermometer, Aquarium Thermometer, Digital Temperature Gauge, Temperature Monitor with Sensor, USB Power Supply, ℉ and ℃ Switchable, LCD Display, USB Thermometer Indoor Outdoor - Qooltek Digital LCD Thermometer Temperature Gauge Aquarium Thermometer with Probe for Vehicle Reptile Terrarium Fish Tank Refrigerator(Fahrenheit) --- ## 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.pt/products/73148769-digital-thermometer](https://www.desertcart.pt/products/73148769-digital-thermometer) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-09-15*
