super It works great as a table piece in our home. Very happy with the purchase overall.
Good It works great as a table piece in our home.
Update 3/2018: Expansion of the home network to include a home office resulted in another cooling fan for my crowded computer center (converted credenza, snug). The newest AC Infinity now has a variable speed switch, and costs less. Cabinet temps seldom exceed 5-7 degrees over the ambient room temp. The 120mm seems to be the best fan for the money.
Original review:
Small, but not so small that it can't move air.
QUIET!
Effective
Once "installed" (more like placed in a cabinet), they are set-and-forget.
I purchased 2 of these, being unsure att eh time how effective they would be in a renovated office credenza-become-computer center.
Within the top half of this cabinet space, just under 3 cubic feet (9"h x 18"d x30" w) I have a satellite modem (runs very warm), 2 routers and a switch, and a desktop refurbished as a firewall.
Before stuffing all these components into this space, they occupied the lower half of a bookcase that sat atop the credenza, and all were clearly producing heat. Therefore the notion that these AC Infinity fans (or similar) would be required inside the smaller credenza space.
I started by placing one fan in the rear of the cabinet to push air (cool air from below) across the very warm sat modem and router out to the front of the open cabinet, and there I placed fan #2 to help pull warm air out and into the room.
Both fans run exceptionally quiet, and I needed to check occasionally to reassure myself they were still spinning. There is a subtle movement of air as well, not a breeze; simply lick the back of your hand and hold it 2 feet away and you will notice the cooling effect on your skin (an old IT "procedure" for detecting failed equipment fans, always works if not sometimes salty).
An indoor/outdoor thermometer served as a great way to measure temps outside the credenza and deep inside (placing the remote temp sensor near to the warmest component, the sat modem in my case). For 2 days the interior cabinet temps remained within 6-9 degrees of the room temp.
So I removed fan # 2 (front of the cab opening), all without more than 1 degree increase resulting.
Bottom line: small but moves air (don't expect a whirlwind or obvious breeze, it's pretty subtle), and very quiet.
The rubber feet on all corners eliminate any vibration noises or humming, and also keeps the fan from moving anywhere.
The alternative might be the AI-MPF80A2 dual 80mm fans (52cfm total) if space is an issue.
If heat is more of an issue than what I described here, consider the AI-MPF120A2 dual 120mm fans, 104cfm total.
Depending on how my single 120mm handles heat this coming summer, I may opt for this dual 120mm fan setup.
As for the optional fan thermostat and speed control, I simply let my fans run off any available USB port and do their work.
Recommended, keeping your gear cool (or not hot) at this price is great insurance. It works great as a table piece in our home.
