*** Please note this is my first ever review of something like this and my knowledge isn't great***

NZXT Sentry LXE Fan controller.

Ok. So I got this about a month ago and decided that I'd live with it for a few weeks before I made my mind up. I apologise for these images, in my excitement I didn't take any of my own so I've 'borrowed' these from Google. All the images are clickable for larger versions

Firstly I will say that yes it's an expensive choice for a fan controller however there isn't on similar on the market currently.

Unboxing

The box is fairly big compared to some fan controller boxes I've seen on other reviews.



Opening the box you are presented with a well packaged and protected product.






NZXT list the specifications as:


Fan Adjustment Range: 3.7V to 12V
Fan Channel: 5
Max watt per channel: 10W
Temperature Module Channel: 5
Temperature Range: 0 ~ 99℃ / 32 ~ 199.9℉
Measurement Frequency: Every 2 Seconds
Temperature Alarm Range: 30℃ to 90℃
Screen Size: 5.27 inches
External Cable Length: 6.8 feet

Now I will point out at this stage that the front box has a different Max watt figure printed on it, it states just 8W whilst the back states the above 10W. For me this isn't really an issue as I am only using a single fan per channel.

Installation


Installation is pretty simple as is the instruction manual supplied which is a double side A3 sheet folded into A5, featuring installation/operation instructions in 7 languages.

The internal control board features 5 x 3-pin fan connector cables, 5 temp probe connectors and Molex power connector. This board fits into an expansion slot in the back of the case but doesn't need to be connected to the mainboard directly.
Also there is a battery slot for a CMOS style battery (supplied) I assume this is for keeping your settings whilst the system is powered off. There is no mention of the battery in the instructions beyond fitting and identification.



Once you've fitted the internal board, plugged in your fan & placed your temp probes that's it for the internal installation.



The external display plugs into the back of the internal board via a 8-pin connector. Now this cable has two connectors, one at either end but one differs from the other in the fact that the end that fits into the display has a retaining clip, the board end does not, however it's a stiff fit.
The display itself takes power from the internal board so there's no need for an external power source.





Operation

Once you've installed the internal board and plugged in the external display it's time to power on.

Now initially when powered up the fan controller pushes 12v to ALL fans. This is for about 40ish seconds. My assumption is that it's to check each fan's max RPM in as they all settle down.

NOTE: This happens at every system power up including resuming from standby/hibernation modes. Again I can only surmise that this is to check the fan's max RPM in case you've made a change.

Initially you will have to set things like the time and date but this is fairly straight forward, just touch the corresponding item and using +/-

In Auto Mode to set the temp alarms you push the number of the corresponding fan (1-5) and use the +/-

In Manual mode to set the fan speeds, again you push the corresponding fan (1-5) but this time twice then the RPM display flashes and you use +/- However the selection is percentage based in steps of 10%. The range is 40% > 100%. Below 40% the controller turns the fan off.

This for me doesn't correlate to the specifications claim of having an adjustment range of 3.7v -12v

12v/10= 1.2v
1.2v x 4 = 4.8v

A clear 1.1v difference.

When changing the RPM in manual mode the fans will respond to increases almost immediately. Decreases however take about 10-15 seconds to take effect and reduce gradually



The display shows all 5 temps & RPM speeds permanently in a list type format. There is a progress style bar divided in to 10 blocks, each block denoting 10% of 12v.
Also for each fan there is an animated fan graphic to show fan operation. If a fan stops spinning the fan graphic stops spinning and begins to flash. If enabled the alarm will also activate.

The screen can be turned off without disturbing the fan controller operation. To do this you just hold the power icon until the display turns off. To re-enable you just touch anywhere on screen. It's a nice feature but the display isn't overly bright nor are the animations disturbing.

The display itself is quite sharp, it's clear and as stated it's not overly bright. There are 3 colours in use, White predominately with blue and orange highlights. It's readable from most angles other than from below but being a desktop display I wouldn't have seen the point. The construction is solid using a mixture of aluminium and plastic.

So far it's done everything a fan controller should do. I've mostly had mine on Auto mode as that's why I bought a micro-processor controller over a manual. However I have used manual to push the fans to minimum when I've been using my PC to watch a movie as my PC is also my DVD player.

One feature I will mention that I love about manual mode is that if a temp goes above what I set in Auto mode, the fan controller despite being in manual will take control of the corresponding fan and push the fan to max speed. So even in manual the controller is keeping an eye out.




Ok so I've waffled on a bit about it's good bits. Now for the bits that aren't so good.

1. The fan connectors - It would have been nice if I could have connected my fan direct to the control board instead of having faf around routing the cables everywhere to keep them tidy. 3 of the fans I have on the controller would have easily and tidily reached without.
2. The battery - Minor niggle but I would have liked to have seen even a breif description of what it's for. I know it's not hard to work out but as most controllers don't have them it'd have been nice
3. Time and date – The time just has AM/PM mode, there's no option for 24hr. With the date it's in US format (M/D/Y)
4. NZXT need to get the info right on the specifications, even the box has conflicting info which is fairly amateur.

Other than those 4 niggles it's still a fantastic fan controller. It doesn't need a 5.25 inch bay for mounting, opting for a desktop style display so you don't have to do chair gymnastics to read the screen

Nice review mate. No pictures though?

I bet the battery is for the clock though. A useful feature is having the time displayed. I often have to check my phone when I'm gaming so having it there on a screen would be handy for me.

In my excitement I didn't take any of the installation and I spent about an hour dealing with cable management (and it's still not good lol) and I don't wanna undo it all to do a re-install for pics.

I suppose I find and post some images from other reviews.

Yeah, it's fairly obvious that the battery is for the clock settings but all the instructions say is "Temperature Control Board battery" which could mean anything.
 
I love these broken english descriptions.

God it must be tricky to sort out that cable mess.

Tbh the cables come packed pretty neat to start with. The temp probes come strapped together like a ribbon cable. But yeah they are a bit of a pain in the backside.

Luckily there's a hole just below the bottom of my mainboard on the mounting plate so the cables have looped through there.

As I said in the review, it would have been better if the control board had the fan connectors and the supplied cables just been 'if needed' extensions.

Additional to my review
as well, I did note this down as a negative point but forgot to mention it. The fan connectors are closed 3-pin, open ended would have been better for users that already have 4-pin fans that wish to use them with the controller.

Looking into buying one of these, though the vagueness of the Auto mode has got me concerned. All I've been able to find out about it is that it "automatically adjusts fan speed based on temperature", but what does that actually mean in practice?

Can you set a high temperature threshold at which the fan is running at 100% power/speed?
Can you set a low temperature threshold at which point the fan is switched off?

You can't set a low point where the fans will turn off, neither can you set your own curves for the auto-mode, they're fixed

At the threshold point you set, whether in manual or auto, the alarm will trigger (flash the corresponding fan if in silent mode) and the fan connected to that probe's channel will be pushed to 100% until the temp drops below that threshold at which point in manual it will drop to your preset speed, in auto it will adjust with the temp drop accordingly.
