The Chief Plenum Rated Fan Kit in Silver is a purpose-built 12V DC cooling solution designed to protect and extend the life of AV components stored in above-tile ceiling spaces. Engineered for seamless integration with Chief CMS storage boxes, including CMS491, CMS491C, and CMS492, this fan kit delivers reliable airflow where heat tends to accumulate. Its plenum-rated construction ensures safe operation in air-handling spaces and aligns with common building codes for suspended ceiling installations. When paired with the NAFT85 inline thermostat, this kit can automatically manage temperature to keep critical electronics within optimal operating ranges, reducing the risk of thermal throttling or component failure. With a straightforward installation that uses only two screws to attach to the housing, the Chief Plenum Rated Fan Kit offers a compact, durable, and efficient cooling solution for professional AV systems in tight ceiling compartments. Whether you’re retrofitting a conference room, media suite, or classroom AV rack, this kit provides quiet, dependable airflow and a low-profile footprint that preserves ceiling aesthetics and airflow corridors.
- Efficient 12V DC cooling designed specifically for AV components stored in above-ceiling storage boxes. The Chief Plenum Rated Fan Kit helps dissipate heat at the source, maintaining stable operating temperatures and protecting sensitive electronics from heat-induced performance degradation over time.
- Plenum-rated construction ensures safe use in air-handling spaces. Built to meet plenum fire and smoke-resistance requirements, this fan kit minimizes risk in ceilings and ductwork while delivering dependable cooling where it’s most needed.
- Easy, tool-free installation with two screws. Simply attaches to the housing for CMS storage boxes, including CMS491, CMS491C, and CMS492, allowing technicians to complete installations quickly without specialized hardware or complex wiring.
- Thermostat-ready compatibility with NAFT85 inline thermostat. If you want automatic temperature control, install the NAFT85 inline thermostat in the cooling loop to modulate fan speed based on ambient temperature, optimizing energy use and preserving AV equipment longevity.
- Durable silver finish and compact profile. The sleek, low-profile fan fits neatly into ceiling infrastructure, preserving aesthetics while delivering robust performance in demanding AV environments and providing long-term reliability in commercial installations.
Technical Details of Chief Plenum Rated Fan Kit - Silver

- Mounting and Installation: Simple assembly to housing using two screws, facilitating quick installation and minimal modification to existing ceiling infrastructure.
- Application: Specifically designed to provide targeted cooling for AV components stored in above-tile ceiling applications, helping maintain performance and reliability in mission-critical setups.
How to install Chief Plenum Rated Fan Kit - Silver
- Prepare the installation area by powering down all connected AV equipment and isolating the circuit feeding the CMS housing to ensure safe work conditions before beginning the installation.
- Identify the Chief CMS storage box housing in the above-tile ceiling space and verify there is adequate clearance around the mounting area for the fan kit and wiring paths.
- Position the fan kit so its mounting points align with the housing’s attachment points. Confirm that the orientation supports optimal airflow direction for heat removal from the AV components inside the box.
- Secure the kit to the housing using the two screws provided. Tighten evenly to ensure a solid, vibration-free connection without over-tightening, which could distort the housing or affect airflow.
- Connect the 12V DC power supply according to local electrical codes. If you’re using the NAFT85 inline thermostat for automatic temperature control, install the thermostat inline within the fan circuit as specified by its instructions, ensuring proper polarity and secure connections.
- Restore power and test the system. Verify that the fan engages correctly, verify airflow through the CMS housing, and confirm that any thermostat-based control operates as intended. Listen for abnormal noise and check for vibration, adjusting mounting if necessary.

Very comfortable pillow
Size: Queen (1 Count), Color: White
I’ve been sleeping with this pillow for a few nights and I really like it. It’s soft but still supportive, and it stays cool during the night. I also like that you can adjust the filling to make it more comfortable. Definitely helped me sleep better.

Fantastic pillow for the price, adjustable is a different ball-game entirely.
Size: Queen (1 Count), Color: White
Overall, I'm quite pleased with this. The fact that it is fully adjustable (adding or removing foam, and they give you a bunch extra) is a massive boon as I like pillows to be pretty low profile. It feels nice to the touch, and compresses nicely but not a ton like down. The memory foam that is inside of it seems to be combined with some kind of a harder material, it's all shredded so I can't tell what it is, but it seems like maybe plastic or something of the kind. Hasn't been an issue in any way, but was just weird feeling it when removing foam.
I took a point off because there seems to be some false advertising going on. You can see in their picture that there is a tag that says bamboo side, the other side of that says cooling side. They also mention it in their advertising. As far as I can tell that is not true at all. The cover unzips so that you can remove the material so you can see that there is nothing on either side of it, and both sides appear visually identical to each other. Certainly I would NOT call this a cooling pillow in any way. It's maybe decently cool if you leave it in a cool place for a while, but over the course of the night warms up quite a bit. I did not notice any appreciable difference in the cooling of either side of it.
There is a definite noticeable smell to it, but I wouldn't call it 'bad' like most memory foam things are when they come from the factory. It smells kind of like some kind of cleaning solution in a noticeable but not unpleasant sense. All in all, for the price this is a fantastic pillow and I would definitely recommend it.

The BETU Cooling Pillows effectively dissipate heat and maintain a comfortable temperature, allowing me to enjoy a restful and uninterrupted sleep. The cooling technology is truly a game-changer for anyone who tends to overheat during the night.
The pillow covers are another bonus. They are soft, breathable, and easily removable for washing, ensuring that the pillows remain fresh and hygienic. The white cover adds a clean and elegant look to the bedding, making them aesthetically pleasing as well.
The king size is generous and luxurious, providing ample space and comfort. Whether used for sleeping, lounging, or reading in bed, these pillows offer an unparalleled level of comfort and support.

Cool, Supportive, and Great for Hot Sleepers
Size: Queen Size Pack of 2, Color: White
These cooling pillows have been a great upgrade for my sleep. The shredded memory foam provides nice support while still feeling soft and adjustable. I like that the pillows keep their shape and don’t go flat during the night.
The cooling fabric really helps if you tend to sleep warm. They feel breathable and comfortable, especially compared to traditional memory foam pillows that trap heat. The queen size is generous and works well for both side and back sleeping.
Overall, a great value for a set of two pillows. Comfortable, supportive, and noticeably cooler than my old ones. I would definitely buy them again.
