5.0 out of 5 starsGreat all the way with NO problems.
By Pricepal on March 8, 2010
Style Name: Sentry LX Fan Controller Verified Purchase
As far as the 3 pin connector issue presented by other reviewers.

I have bought 8 of these in the last 6 months and EVERY fan connector comes with a 3 to 4 pin adapter so its no problem there.

Another review complained that there are "too many wires".

Some people should not be building computers if they cannot take the time to route and secure wires.

As far as operation goes, all of my builds have been hassle free, everything working fine.

I never hook the cpu fan to this, always to the motherboard, that way if something happens to this controller, the mobo will continue to operate the cpu fan.

Leave plenty of the wire tucked in behind the controller, that way when you need to pull it to change the battery, you will not have to unhook anything, just change the battery and put the controller back in place. Its much easier if you have a second pair of hands available when changing the battery.

5.0 out of 5 starsReally slows fans down and reduces fan noise. Good quality.
By M. Lam on March 21, 2012
Style Name: Sentry Mesh Verified Purchase
Bought this because my 5 120mm case fans running at 100% was too loud and unnecessary for normal computer use. It is perfect!

Pros:
- Unlike most 5.25" bay manual fan controllers out there, it actually has 4 places you can screw it down into the bay so that it is nice and stable.
- One 4-pin Molex plugs into the cable from your power supply and there are five 3-pin female fan connectors to plug into. Very logical.
- Wires are long enough to make it around my mid-tower case wherever I want them to go. Might not be long enough for large cases though.
- Has a nice look and feel to it. The sliders move slowly and firmly, which is good. The black mesh matches my Cooler Master Elite 430 case.
- At the minimum 40% setting, my fans spin slowly and quietly. At the max setting, the fans are 100%. I like that I can control each individual fan.

Cons:
- The 4-pin Molex only has one of the grounds connected to an actual wire. NZXT cheaped out and neglected to provide a fourth wire to connect the second ground pinout so they could simply run three wires. Lame.
- Also the white LED doesn't tell you anything but is so bright that it bleeds through to the two sliders on the right closest to it. If you're picky about that sort of stuff, you'd have to block it off somehow.

Overall an excellent buy!

4.0 out of 5 starsGood product for the money
By Nick K on December 21, 2009
Style Name: Sentry 2 Touch Screen Fan Controller
This is probably one of the better fan controllers on the market, considering 90% of the fan controllers on the market are terrible. For 28 bucks, this is a pretty good deal. Ill break down the good and bad below:
Pro's:
-good price
-works fine
-lcd is cool to look at
-controls all my fans perfectly
-temp is more or less accurate
-Easy to install/use
Con's:
-Creates a huge mess of wires
-Wires are superglued to controller, so when taking it out, u have to take out all the temp sensors as well.
-Bad instruction manual, luckily it was fairly straightfoward anyways.
-BEWARE! THE COOLERMASTER FAN AMAZON SAYS IS FREQUENTLY BOUGHT WITH THIS PRODUCT IS NOT COMPATIBLE WITH THIS FAN CONTROLLER!
It didn't work for me, or anyone else I have talked to. im pretty disappointed that amazon did not recognize that.
-Hasn't happened to me, but ive read lots of reports of screen breaking, and cust. serv. is a huge run around.

Like I said, for 28 bucks, this is a great deal. If it were $40, I would get something else, probably not w/ lcd. This controller is pretty much hit or miss, so good luck if you choose to buy it. If you get one that functions, then it ends up being a very useful and quality product. If not, then you're screwed.
-Nick

5.0 out of 5 starsSo loud that I didn't even want to use my PC and regret my case (CM922 - which is a nice case otherwise)
By Gabiguchos on September 14, 2015
Style Name: Sentry 3 Verified Purchase
To start things this off this is the only fan controller I have bought/used. After building my PC my case fans were way too loud (three pin so connecting to the motherboard wouldn't do anything). So loud that I didn't even want to use my PC and regret my case (CM922 - which is a nice case otherwise). I bought the Sentry which can connect up to 5 fans and connected my three case fans to it. Installation was easy - I just screwed it into the slot and the wires were long enough to reach my rear case fan without any problem. I linked my fans together, set them to 40%, and my noise problem was gone. I don't think I'll ever have a PC without one of these again. The LCD turns off if you find it annoying and I haven't had any real problems with it. If your case fans are bothering you I highly recommend getting this.

I only used three pin fans but this supports 4 pin as well. Also it included zip ties.

5.0 out of 5 starsWorks good for me ...
By S.L. on June 8, 2012
Style Name: Sentry LXE
I've been using this fan controller for well over a year and have had no trouble with it at all. It's part of a high-end custom build.

The computer has 5 fans controlled by motherboard headers and 5 fans controlled by this device. The motherboard is an ASUS Sabertooth 990FX with "thermal radar" fan controls built in, CPU is an AMD FX8150 "Bulldozer" octocore. Everything is mounted in a Cooler Master 932 HAF case which has 3x240mm fans factory installed. CPU cooling is provided by a Corsair H70 water cooler with Delta fans in a push/pull configuration on the radiator.

Those Delta fans can get VERY loud at full power (3500 RPM @ 100+ CFM) and that is one of the main reasons I wanted a fan controller like this. @ 2000-2200 RPM they are nearly silent. This controller is very easy to adjust to get the performance you need without noise you don't need but still ramp up the fan RPMs when you really need the cooling power. The computer has a fairly serious overclock @ 4.0 GHz with a 4.6 GHz turbo. This works great BUT the VRMs tend to overheat (not the CPU) so I had to custom mod some smaller fans. I put a fan on the VRM heatsink, the RAM, and the North Bridge heatsink. The pump for the water cooling is on the motherboard CPU header, being a pump it needs to be at max. RPM constantly, CPU temp is controlled by the radiator fans.

I have the temp sensors strategically installed to run the fans. Here's my configuration-

TEMPS (Left side of controller) Fans (Right side of controller)

North Bridge Heatsink (110 F.) North Bridge Heatsink (2700 RPM)
RAM (105 F.) RAM (2000 RPM)
VRMs (Voltage Regulator Modules) (105 F.) VRMs (2000 RPM)
South Bridge Heatsink (125 F.) Radiator PUSH (2200 RPM Delta fan)
Radiator (105 F.Read more ›
