NOTE: This review is for the 5V 6-pack version T3SYC3-6 SYNC RGB. Make sure when you're checking reviews for these budget style RGB fans that you're filtering for the specific model that you're looking for. Every company that makes these, for some odd reason, makes at least 3 different models and because of how Amazon listings work the reviews for all the different models get bunched up into a huge mess of conflicting opinions.

Now onto the review. Wow, these fans are incredible. They push a substantial amount of air and are actually shockingly quiet, and they look fantastic. All the connectors are completely standard. It comes with a fan hub that's fairly large but has 7 PWM fan ports & 7 3pin 5V RGB ports, takes molex power, and connects to a PWM fan header on your motherboard. It can also connect to an Asus Aura Sync header or other brand equivalent, but I haven't tried it. This allows you to control every fan and an extra fan or RGB accessory. What's awesome about this hub is that it has a reset switch input to control the lighting effects. You can either hook up your case's reset switch connectors to it to control lighting with your reset switch, or you can use the included mini switch it comes with. It can be a bit inconvenient since the hub will obviously be inside your case, so you'll have to get creative & route it outside your case somehow (the wire is long enough to do so). The fans themselves aren't actually PWM but are rather 3pin DC, but the hub does send & receive PWM signals to & from your motherboard. I'm not entirely sure if this qualifies as PWM, but I've heard of other companies doing this before (such as the NZXT Kraken daisy chaining its PWM fans through only 3 pins), so I wouldn't worry about it. Daisy chained on the PWM cable that goes to your motherboard is a female 3pin 5V RGB cable that will allow you to control the lighting of the entire hub with your motherboard if you want to. The build quality is where they had to cut corners. They feel cheap & light but that shouldn't be an issue because you aren't going to be fiddling with case fans once they're installed. The holes for screws are too tight and will take a good amount of force to secure the first time. The fan blade design is a hybrid between airflow & static pressure, so they should work fine as either case fans or radiator fans. At high RPM they're relatively loud (as is most fans). They still move a good amount of air at low RPM & with 6 fans I sure hope you're not running them all at 100% anyway.
Pros:
Great airflow & acoustics
Beautiful addressable lighting
Perfect light diffusion through the fan blades
PWM controllable
Completely standard connectors (3 pin DC fan control & 3 pin 5V RGB)
ASUS Aura sync/other brand equivalent compatible
7 port fan hub included
Comes with velcro cable ties
$40 for 6 ARGB fans

Cons:
Hub takes molex power
Build quality is what you'd expect for $6.50 fans
Default hub's lighting control isn't the smoothest I've ever seen but has decent effects.

Overall I think this is an incredible buy for $40. If you're like me and can't justify purchasing 3 fans for over $100 (cough Corsair), then these are a must have. Most RGB fans at this price point have proprietary 6pin connectors that don't let you control the speed or the effects via your motherboard. These fans, however, are COMPLETELY standard. upHere is really setting the industry standard with budget RGB fans here. I was skeptical of these at first since they were so cheap, but I would buy them again 7 times over.

I've used these fans in more than 50 builds and they are amazing! I build and sell gaming computers on the side of my main job as an IT Admin and I was tired of using the $100+ 3 Fan kits from Corsair, Thermaltake, etc... So I wanted to find an alternative that were not only cheaper but the quality was comparable as well! So after trying quite a few of the cheap fan kits I landed on the UpHere brand ARGB fan kits that come in 5 or 6 fan kits with controller, mounting hardware, Velcro straps, etc... These fans have really decent airflow, great color, very bright and look amazing! For less than $50 you get 6 x fans, controller, 24 x screws, and 6 x Velcro straps. The build quality is surprisingly really good! They don't feel like those flimsy cheap fans they feel heavy and thick like the premium Corsair and Thermaltake fans! I've also replaced ALL 10 of the Corsair fans in my personal rig with these UpHere fans and they are overall brighter AND my temps are exactly the same! Not a single degree difference in temps! So for those of you wondering if they perform the same as an expensive premium fan, yes, they do! So at least in my personal experience they worked out amazing! Also decreasing the overall build cost of the systems that I build and sell! Now keep in mind that if you want to control the fans with your motherboard software you have to have a 5v 3 pin RGB connector on your motherboard as they are 5v fans! I've seen reviews from people that were mad because they didn't work with their 12v connector on their motherboard when the product listing clearly states that they are 5v!!! So someone shouldn't be mad over their own illiteracy and stupidity! HOWEVER!! There is a solution for those of you that only have a 12v header on your mobo and want to use these fan kits! You can simply use a 5v to 12v converter! Like: https://www.amazon.com/EZDIY-FAB-Converter-Transfer-Splitter-Motherboard/dp/B082KJH2T3/ref=sr_1_4?dchild=1&keywords=5v+argb+to+12v+rgb&qid=1605816174&s=electronics&sr=1-4 OR if you want to just use a remote to change the lights you can get this: https://www.amazon.com/LEDdess-Rainbow-Controller-Strip-Remote/dp/B07JZCNPNV/ref=sr_1_11?dchild=1&keywords=5v+argb+to+12v+rgb&qid=1605816174&s=electronics&sr=1-11 OR just use the built in button that you can wire to your front panel reset button or use the button they include with the controller. Either way there are many different ways to integrate the fans into your systems environment! Never again will I spend over $200 for ARGB fans! I would completely recommend these to anyone whos looking for a great performing great looking RGB fan kit!

Great value RGB fans. I have a MSI b450 gaming pro carbon AC motherboard with a 5v 3 pin Jrainbow header and I haven't have any of the issues others have complained about them not being compatible with motherboard RGB control. They are a little noisy but I'm hoping some rubber mounts will solve that. Don't think it's an rpm issue as my monitoring software says it's only going at 750-900rpms. Although it's my first PC build and I don't entirely understand how to control fan speed so maybe they are just running too fast (or maybe 7 fans is just never going to be quite lol). Routed my CPU fan through the hub provided as well and plugged it
all into 4 pin CPU fan header on mobo so to my understanding the default PWM setting should handle everything from there? Installation wasn't terrible but I definitely had to do a lot of googling to make sure I did it right as the provided instructions were very basic. Only other thing I can say is I was not prepared for all those damn wires, what a hassle 😂. At end of the day though for $40 they're definitely the way to go if you want to add some sweet RGB to your build for a low price.

OK lets start with the bad....the controller board did not interface with my motherboard...plugging in a single fan direct to the motherboard, i could control colors....plugging in all 6 fans with the controller/distributor, ONLY the built in controller on the distribution box would work and never synced up with the LED strips on the other RGB ports of the motherboard....plug in a single fan and all LEDs matched like they should and i could control it....

i would keep the set if the fans all worked like it does when a single fan is plugged in....these fans look great and move a good amount of air, plus they are quite....LEDs even look good

dont know how the return is going to go but i would take a chance on buying them again for other builds IF the return goes well....i tested every fan and only the controller link was messed up....

if you do buy this set remember 1 thing.....you will be hiding a box 5 inches tall by 2 inches wide with wires coming out of every side.....each fan has long wires so big cases will be fine but smaller cases are going to have massive bundles of wires to hide....at least they included Velcro straps

You do get what you pay for but these are pretty decent for a budget build. Speed is non controllable so it's one speed all the time. Rgb is pretty decent actually with alot of different modes and colors. Comes with a hub able to run 7 rgb fans off sata power and mobo pins that works great and syncs to my gigabyte mobo easy. A little loud but again cheap. I'll be thrilled if they last a few years
