How to Fix Lorex Dvr Fan Noise-Step by Step Guide

When the Lorex DVR generates grinding or buzzing loud noise, the source of the noise could be either the fan or the drive disk. We propose that you first determine whether the fan or the HDD causes the problem. To determine the source of the noise, listen to the DVR. If that doesn’t result, disconnect the DVR from the power source and take out the top before plugging it back in and turning it on.

Switch off the DVR and loosen or tighten the fan using a screwdriver if the noise is generated from the cooling fan. The vibration may cause a buzzing noise if the housing of the cooling fan is too tight or too loose. Also, ensure that the fan is free from any dust since dust accumulation may generate some noise.

If the noise is generated from the hard disk drive, you will have to replace it. When a hard drive begins to grind, it is either burned out or on the verge of being burned out. Continue reading this article to get more information about the Lorex DVR fan noise.

To solve the problem of excessive fan noise, follow these steps:

• Make sure the DVR / NVR is set up on a level, sturdy platform.

• Ensure the DVR / NVR vents aren’t blocked (i.e., nothing on or around the unit is blocking airflow).

• The system should be rebooted. Please turn off and disconnect the power supply for about 30 seconds to power cycle your recorder. Reconnect the writer and turn it on.

• Make sure that the fan is in good working order.

What causes the DVR fan noises and how to fix

1. Maintain the temperature of your device

Keeping a DVR or NVR in a restricted space, such as a stuffy office or a shelf pressed against a wall, can cause it to overheat and draw in and hold excessive dirt. If your overheated machine is hot to the touch, turn it off immediately and transfer it to a well-ventilated area with at least a one-foot clearance behind and over it.

Proper ventilation is essential for keeping a busy NVR cool and running smoothly. If at all feasible, keep your unit in an air-conditioned environment and out of direct sunlight. To avoid unintentional power outages and surges, use a backup power supply. Heat monitors have become more compact, allowing them to be put near the unit and monitored wirelessly via a smart device.

2. Keep your DVR or NVR in good working order

Cleaning your DVR or NVR system of dust, dirt, and dander is the most fundamental upkeep for keeping interior temperatures in check. Earlier DVRs rely on heat dissipation through chassis vents, with the CPU being the only fan in most cases.

Shut down your device at an off-peak period and do maintenance on it regularly. Video surveillance is a continuous operation that generates heat and vibration. Ensure that the fan vents and blades are clean and debris-free. Clear away any cobwebs or dust bunnies inside the machine with compressed air. Check your fans to see whether they’re cooling the unit properly and replace them if necessary.

3. It’s because you’re using the Wrong Drives

Surveillance drives aren’t like regular hard disks. Cache optimization for continuous data streams, larger read/write allocations, and firmware compatibility for high-definition cameras are all included.

Many people believe that regular or NAS-tuned drives will perform best in new multi-bay NVRs because they resemble a typical NAS box. That isn’t the case at all. A standard desktop drive is designed to have a total workload of 10% to 20% (at most) that of a surveillance disk. The 90 percent write and 10% read on average of a conventional surveillance drive is not designed for NAS drives.

The surveillance hard drive is the heart of the digital surveillance video storage system. It’s made for usage in a DVR or NVR that’s on 24 hours a day, seven days a week. Surveillance problematic drive consumption is often moderate to high, and any hard drive failure will impact several users. These drives are expected to have a long mean time between failures.

Maintenance Tips for Surveillance Systems in a Nutshell

If your surveillance system begins to overheat or generate excessive noise, take the following measures to ensure that your investment is performing at its best:

• Shut down the machine, open the chassis, and gently clean any dust or debris within the device regularly. Also, make sure that none of the fans are blocked or broken.

• Use the appropriate drives – Ordinary desktop drives won’t cut it in the DVR or NVR’s challenging, always-on environment. They are more prone to overheating and causing excessive vibration, resulting in video degradation or loss.

• Maintain a well-ventilated environment for your equipment — Make a dedicated space for your gadget with an open-backed shelf or store it in an excellent location among other electronic devices.

Ways to avoid the DVRs from overheating

The most common cause of digital video recorder (DVR) failure and noise is heat. Therefore, how is it possible to prevent overheating to extend your DVRs lifespan and improve video surveillance? We’ve included some helpful hints below.

• Keep an eye on the temperature.

• Always keep an eye on the temperature of your system. To assess the implications of heat liability, consider both internal and external factors:

• The temperature of the area where your DVR is kept is crucial in ensuring a secure environment. Maintain a cool, well-ventilated environment.

• It’s essential to use an electronic thermometer for monitoring the ambient temp when the system lacks a built-in reader.

• It’s essential to leave the system to cool on its own during the downtime. As a result, do not run it when it’s not in use.

a) Make sure you ventilate

Your system will not overheat if you have proper cooling and ventilation installed. Prevent your DVR from overheating by taking the following steps:

• Increase ventilation by installing cabinet fans or spot coolers.

• DVRs should not be moved while in use.  

• Avoid stacking the gadgets on top of one another.

Connect with your security vendor to discuss available alternatives if you have questions about how to keep the temperature of your DVR in the safe zone.

b) Cooperate with your security provider

 There are steps you can do to extend the lifespan of your DVR; starting with robust and trustworthy equipment is essential. Before you buy anything, make sure you ask the merchant the following questions:

• Is it necessary to update my gear regularly?

• Is there a warranty on the equipment if it overheats?

• Will you be able to analyze the damage or facilitate the required repairs if my DVR overheats?

• Is professional cooling equipment installation available through your company?

• Is there a cool-down mode on my DVR if it hits a specific temperature?

Frequently asked questions:

• How does the Lorex DVR cost

The price of the Lorex DVR ranges between $550 and $49999.

Conclusion

Your Lorex device includes a fan to keep the DVR cool, and some fans are louder than others. Your Lorex device also contains a hard drive, which may make clicking or whirring noises while recording or processing program data. Always keep your Lorex device plugged in.

To conclude, the Lorex DVRs must be well ventilated. If it’s inside a cabinet, consider moving it to a more open area. There must be nothing on top of the device. If your Lorex device is placed on another electrical component that generates heat, the temperature on your Lorex device may rise, and the fan may run more frequently, causing the loud noise.
