Thanks! I've got a couple of videos planned that will hopefully cover some of this. As for why I made it: I got myself a couple of 10-gigabit network cards designed for servers. Servers typically have much higher airflow than your average PC, so the cards were overheating. The usual solution is to zip-tie a fan to the network card, but I wanted something a bit nicer.
@@CodeSevenDesign Network card didn't cross my mind at first, I was thinking a raid card or pcie storage card would benefit from this. Super sleek design, love it!
@@CodeSevenDesign This is exactly why I have a fan zip tied to my current HBA server card in my tower workstation :D What a beautiful design. I absolutely love the simplicity.
@@manitoba-op4jx I'm going to guess no because that would require an actual pcie device present on the board to offer the sensor and control, and that would bump the price way higher.
Am I the only one in here that immediately thought at least 4 reasons as to "why"? :D Cooling NICs, HBAs, GPUs with passive heatsinks or heck, even the back of some GPUs, those M.2 carrier boards... It looks really awesome and it's honestly a great idea. Good luck with it man!
My graphics card is water cooled and the NVME drive underneath it gets no airflow. I have jerry-rigged a fan to cool it. I've wanted a PCIe powered fan forever.
There used to be cards like this with 2 fans and a rpm adjusting slider at the pcie cover from the outside so you can change fan speed without opening the case
a couple other ideas... 1) multi fan version like a GPU. 2) a cage fan exhaust option. some cases re quite limited on airflow so having a way to pull air out could do wonders in restricted airflow devices. 3) have it controlled by the pc similar to a normal PC fan 4) a temperature sensor version, when it starts getting warm in whatever case, it can just come on without the push button.
u know, to cool down graphics card, or any other pcie 'stuff' a lot of people using ATX Mobo. So it makes sense. It can also be use in home server or some sort.
Been looking for something like this for some time and its really cool to see it put into production. My PC is an oven and needs all the help it can get
Looks awesome. you should program and test during the same step to decrease assembly time. it would require a bit more electronics and a new test jig, but with the pi its 100% achievable.
You're getting a lot of "why" but i actually was looking for exactly this product a year or two ago. Couldn't really find anything. Going to go check out your site now. Glad the algorithm recommended this video.
I personally like to use a large flat file to clean up the edges of PCBs. I think a sheet of sandpaper glued to something flat would also work. With the shape of your fan controller, it would be very quick to just slide it over a fixed piece of sandpaper.
That is absolutely superb and a much better solution than I used which was some generic slot brackets, a laser cut 3mm wood plate to hold the fan and a 3D printed mount that goes over the PCIe slot to hold everything steady. :-)
while having limited uses, it is a really nice addition even just to be sure on summer season to keep airflow moving on really small and fanless cases (or the ones that barely have a spot for fans) I love this idea!
Love your work, I'm in Australia too and do some retro electronics projects occasionally for my own purposes. I made a desk fan design using a 12V fan powered by USB with an onboard boost converter, although my PWM is controlled by a pair of NE555 timers. Granted a microcontroller would've been the easy approach but I opted for a timer-based design instead.
This by itself is already a very interesting and useful idea for servers. I think there is greater potential here to also add a second or third header that can be controlled independently, but I have no idea how much extra cost (both monetary and time) that would tack on. Great project and I can't wait to see more!
really cool! definitely looking forward to seeing more! the thing i would be most interested in is how you made both the programming and testing fixtures, and how they work.
Brilliant! I have an idea: make the same thing, but without a PCI interface. That way, you can use free slots in the PC case and the fan could be connected conventionally via the motherboard.
Hey, just a little bit of an engineer here as well. And this is really cool demo for assembling, I like it! Currently also working on embedded project (which is something rather new to me) and your video is quite interesting to see regarding pipeline :)
love the design and process of individually testing the pieces. maybe for after separating the boards try using a knife sharpener like the really cheap ones, that have two sharpening disks. One or two passes through that should make for consistent results.
Thanks for the video! I appreciate the quality and application of QA processes similar to those in industry, it's certainly an interesting subject. Nevertheless, after reading some comments, I digress and reflect on another topic... just to brush up on the theme of how sad it is to live in an underdeveloped country. Let's say I bought a board complete with a fan. This would cost me $80. Converted to our local money taking into account today's exchange rate (10/07/2024, 1USD ≈ 5.50 BRL), the board+fan combo would result in about 440 Reais (BRL), our local money. On top of this 440 Reais, we include federal import taxes (60%) and state taxes (17%, calculated on the value of the product plus the 60% federal taxes), giving us a total of approximately 408 Reais, equivalent to 92% of the original product value. The price of the board and fan would be, for us, 848 Reais and some change. I'm not considering shipping costs, which would be taken into account when calculating both taxes. The average salary of a Brazilian at present date is approximately 3200 Reais by month (90% of the population earns less than this amount per month). This product would be equivalent to 26% of the total monthly earnings of an average Brazilian. One week's work.
This video was so to my liking that I went to check what other videos you've made. Then I realized you have exactly one video. might as well subscribe.
Does this actually use the pcie edge for power only or are you connecting the the SMBus (System Management Bus) it is an I2C derived protocol and you could have the fan actually show as an available controllable fan withing the os (with uefi i think also in "BIOS")
I initially wanted to have SMBus control, but it turns out a lot of motherboards don't bother implementing SMBus on the PCIe ports. If I were going to make a version with fan control, I think I'd use a PCIe lane - maybe with a PCIe to USB or UART converter.
@@CodeSevenDesign Thats fair, but if you're doing a 2nd revison and have the spare time, try implementing a simple SMBus interface. The new ATTiny family is almost as cheap as the attiny13 and has hardware i2c. You could even toss in an ntc to dynamically adjust fan speeds and report temps via i2c.
Fun fact: Per the Intel Standard, behavior below 30 % PWM duty cycle is undefined. So at 25 % fan speed, some fans may run at 25 %, others will default to 30 % and others again will stop completely.
Good catch! I originally had the firmware run the fan at 30% for a couple of seconds before dropping to 25% to ensure it starts correctly. After testing with about 20 different fans, I couldn't find one that wouldn't reliably start at well below 25%. Another option would be to output 30% instead of 25%, but I'm too much of a perfectionist to do that!
@@CodeSevenDesign Running at 30 % at first is called a start-up pulse in the standard. I have fans in my collection that show all kinds of behavior, but I feel like the more modern fans cope better with non-compliant fan controllers.
I saw this (or something similar) and was set to buy soon! I have 3 x Rosewill 4U's and the have all my PCIe slots full and even with a mid-wall fan, the last card in the slot still gets hot. I was going to optimize a bit and put this in the last 7th slot. There used to be more PCI slot fans on the market in the early 2000s but what's left now is just plain ugly and low quality or are just braces for standard fans. This is done so well. Thank you for making this.
High manufacturing cost is the unfortunate side effect of a low volume 1-man operation. That said, at this pricepoint I'd just pay a little bit extra and get a dual chamber case set up for intake at the bottom.
I made a mechanical matrix keyboard with LED backlighting for an 8-bit computer, the BOM cost was around $100 (or even less if you supplied your own keycaps) and people complained it was expensive. As if the $40 for a Redragon keyboard is what it should cost. I can barely squeeze the PCB itself and mechanical switches into a $50 budget. I appreciate feedback but just complaining "too expensive" without proposing a viable alternative is just insulting to designers.
@@foufou81 What does that even mean? The backplate isn’t for cooling 99% of the time. The backplates that have thermal pads won’t see any benefit from a fan pulling hot from CPU cooler either.
Modern Lian Li cases (and probably other brands too) have mesh around the PSU area and places to mount fans that can blow air onto the PCIe slots from under. For example the lancool 216. I think its a bit more of an elegant solution to have (reverse flow) fans mounted on the case, but nonetheless a cool project!
You could turn this into a million dollar idea: Make this board packed full of 4 pin fan headers and make It compatibile with FanControl (open source program). This way you can get software control on old unsupported motherboards
A suggesstion: The button can be moved to the back panel of the controller, because if it is installed in the case, it is not convenient to change the speed of the fan.
Have you considered creating modular versions with 2 or 3 fans? For example, to improve the airflow to the graphics card. There's literally no room in my case for another PCIe device. But the idea is really interesting. I like the approach to assembly and quality control.
First video on the channel, it was amazing! Loved to watch this and hope to see more like this in the future, you got yourself another subscriber 😋 Could you show more how you made the pogopins be straight and exact position them? Did you use 3D printing for this or any other solution? I've been looking for how to make pogopins straight and reliable, just like yours looked to be. Sorry that it isn't about the PCIe fan controller, I just think that is simple and so much self explanatory, and you showed everything for my needs 😋 I think the fan controller is amazing, no doubt about it! ❤
You know what would be absolutely genius ? The same thing with a 120mm fan in a 2 slow contraption wilth a closed off bottom side so the fan suck air from the back of the case. It would provide the hottest side of the GPU with 100% fresh air. It would require a 3d printed shell and a 2 slot PCIe plate, opefully very open.
Yo, the video looks so good I thought you were a massive tech channel that I was already a sub lol, you earned a sub, nice video would like to see more
Instead of the Scraper maybe you could use a large Deburring Tool so it "deburrs" both sides at the same time and shoudl also get the little nib left behind by the break-off
You might be able to use a knife sharpener to run the board down the middle, it would grind down the sharp edges and be very quick to just slide through like a credit card.
This would be pretty cool if you made a 2x 120mm fan version with some type of shroud that focuses air directly on bare gpu heatsink. That way you can remove the stock gpu fan and shroud
pcie fan controller YES PLEASE now i just need 32 fan outputs aswell and pcie drivers and some simple UI to have fan curves or temp control somwhow and it would be mint
Excellent work, good craftsmanship, and It’s cool to see a modern take on a PCI fan. I remember way back when brands like Antec, Arctic, and Phobya had similar products to cool down monsters like the GTX480 and Radeon 6970. Excellent execution sir, keep up the great work.
3 x 120mm and 140mm fan options with integration to the program called fan control and libhardware for unix systems.. If you do this I will buy 5 of them. I have lots of computers that could use this. Subscribed, thumbs up, and sharing with my other PC friends.
Something ive wanted to do for the longest time is something very similar but have able to control all my case fans so i can set custom curves outside of mobo or proprietary software
Any plans on adding a connector for a NTC Thermistor for temperature dependent speed and connecting the microcontroller via I2C to SMBUS and have it show up as a lm-sensors compatible fan/temperature sensor? And maybe a multi-fan version with some 4-Pin connectors all individually controllable via SMBUS?
I have an idea, but i hope you can read my comment: Can you build this like a 240 or 360mm version with a attachable shroud on the backside That can be the best and cheapest option for a gpu fan mod, it had so much potential! The shroud can be use to fit correctly the gap between the Fan and the GPU and it will looks cool. Many user can do after that build their own 3D printed shrouds and makes an unique looking system.
It looks like this controller supports analog input it would be better to use small variable resistor to set the fan speed, yea it adds to the cost, but given the manufacturing cost it is very little % wise. you could use a rgb led and use the output color to indicate the fan speed, maybe you could make this visible, configurable from outside of the case at the bracket Could also use some through hole pads so a person could add a header to reprogram the IC Aside from this being neat and clean cable management, it would be more economical to just get brackets that have screw holes that line up with a fan's mount holes, i managed to find one that would fit a 60mm fan
This is awesome, but $50 is wayyyy to much for something like this as awesome as the engineering is. You could get the PCB printed at a circuit printing facility to reduce costs. You could also make 2 fan variants. A version that takes the output from an existing PWM header and repeats it (like a fan controller) would also be awesome.
How long does the process from start to finish last? How much foes a fan cost? How many fans do you need to sell to get all the machines and tools paid off? What's your hourly salary on this?
wow. is is possible to show or roughly explain the whole process from design to finish? Like what software to design and CAD etc etc. How you designed the PCB, which are the correct manufacturing contractors to find , etc etc
its really cool but one downside seems to be a lack of automatic/temp based control for the fan speed. its really cool and look way better than what i do when im using datacenter/server hardware in my homelab computers. i just 3d print adapters that stick a fan where its needed and plug it into the motherboard. maybe some ideas to go with for a V2 able to be more fexible in where the fan can be mounted and with other sized fans, smaller and larger. some way to expose yourself to the host to control, daisy chain an existing pwm or via pcie or own thermal probe
Can you have more ports to plug more fans? I also thought that the controller would show up in your OS. I have some PCIe 1x ports available, but just putting ONE fan there seems like a waste. I hope the next iterations has more connectors.
It’s very cool, but I’d be interested in “why?”. Given there are many ways to do this with fan kits, not to mention built in to MBs and via software I’d love to know what made you want to make this (if anything beyond “just cause I can”) 😊
Initially I though this is for people that is running out of fan header on their mother board, but I guess adding a fan into your pcie slot might have some use as well.
Neat, I'm just wondering if it is possible to have fan speed control via PCIe using software on the pc like speedfan. Or maybe have it temperature controlled using the micro and a thermistor. Just some ideas.
It's really cool product, but at the same time hard to justify spending $80 on a fan, considering how low airflow an 80mm fan provides and how much more effective other airflow approaches will be in most situations. Anyone wondering if they should go normal or slim size fan should take into account that regular thickness fan will usually provide higher static pressure than slim fans, which is something you will need in a situation where you'd consider sacrificing a PCIe lane to a fan for airflow.

people ziptied fans to server stuff before... so this is nice organisation upgrade
Me too. I've seen blower style exhaust fans that mount on the PCI slots on the case. I believe Thermaltake used to make those.
There used to be cards like this with 2 fans and a rpm adjusting slider at the pcie cover from the outside so you can change fan speed without opening the case

4) a temperature sensor version, when it starts getting warm in whatever case, it can just come on without the push button.
You should make a two-fan and a three-fan variant.
And an application that can be used to set the fan speed from the operating system.
What use would you have for that?
u know, to cool down graphics card, or any other pcie 'stuff'
a lot of people using ATX Mobo. So it makes sense. It can also be use in home server or some sort.

A dual or triple 120mm version would do great for many applications. This is perfect for those hot 10GbE cards though.
Darn, this is cool I must say!
Well done!
Can u explain to me the use case for this fan? Maybe I’m being stupid but the only thing I can think of is cooling a passive cooled server nic
Raid, nic, HBA in a normal case
A double or triple fan setup next please.
Amazing work man it looks beautiful.. Could you design a small form factor version..
Excellent work, good craftsmanship, and It’s cool to see a modern take on a PCI fan. I remember way back when brands like Antec, Arctic, and Phobya had similar products to cool down monsters like the GTX480 and Radeon 6970. Excellent execution sir, keep up the great work.
Cool. Looking forward to more videos.
i musta hit the youtube recommendation jackpot
3 x 120mm and 140mm fan options with integration to the program called fan control and libhardware for unix systems.. If you do this I will buy 5 of them. I have lots of computers that could use this. Subscribed, thumbs up, and sharing with my other PC friends.
Something ive wanted to do for the longest time is something very similar but have able to control all my case fans so i can set custom curves outside of mobo or proprietary software
Any plans on adding a connector for a NTC Thermistor for temperature dependent speed and connecting the microcontroller via I2C to SMBUS and have it show up as a lm-sensors compatible fan/temperature sensor? And maybe a multi-fan version with some 4-Pin connectors all individually controllable via SMBUS?
Finally GPU that fits my budget xD
I have an idea, but i hope you can read my comment:
Can you build this like a 240 or 360mm version with a attachable shroud on the backside
That can be the best and cheapest option for a gpu fan mod, it had so much potential!
The shroud can be use to fit correctly the gap between the Fan and the GPU and it will looks cool.
Many user can do after that build their own 3D printed shrouds and makes an unique looking system.
can it work on 1x pcie lane im curious sum extra cooling on my gpu under my gpu has 1x laying around
It looks like this controller supports analog input it would be better to use small variable resistor to set the fan speed, yea it adds to the cost, but given the manufacturing cost it is very little % wise. you could use a rgb led and use the output color to indicate the fan speed, maybe you could make this visible, configurable from outside of the case at the bracket
Could also use some through hole pads so a person could add a header to reprogram the IC
Aside from this being neat and clean cable management, it would be more economical to just get brackets that have screw holes that line up with a fan's mount holes, i managed to find one that would fit a 60mm fan
This is awesome, but $50 is wayyyy to much for something like this as awesome as the engineering is. You could get the PCB printed at a circuit printing facility to reduce costs. You could also make 2 fan variants. A version that takes the output from an existing PWM header and repeats it (like a fan controller) would also be awesome.
How long does the process from start to finish last?
How much foes a fan cost?
How many fans do you need to sell to get all the machines and tools paid off?
What's your hourly salary on this?
i dont care what any one says... this is good idea!!!
wow. is is possible to show or roughly explain the whole process from design to finish?
Like what software to design and CAD etc etc.
How you designed the PCB, which are the correct manufacturing contractors to find , etc etc
This is super cool!
its really cool but one downside seems to be a lack of automatic/temp based control for the fan speed. its really cool and look way better than what i do when im using datacenter/server hardware in my homelab computers. i just 3d print adapters that stick a fan where its needed and plug it into the motherboard.
maybe some ideas to go with for a V2 able to be more fexible in where the fan can be mounted and with other sized fans, smaller and larger. some way to expose yourself to the host to control, daisy chain an existing pwm or via pcie or own thermal probe
Can you have more ports to plug more fans? I also thought that the controller would show up in your OS.
I have some PCIe 1x ports available, but just putting ONE fan there seems like a waste.
I hope the next iterations has more connectors.
Like... Why? There is not a single 5-12V source somewhere near e.g. Molex/SATA? Or 3/4 pin header on motherboard?
Its looking good, no doubt, but why?
should make a tri-fan one so you could have up to 6 fans under a GPU depending on what case you use
It’s very cool, but I’d be interested in “why?”. Given there are many ways to do this with fan kits, not to mention built in to MBs and via software I’d love to know what made you want to make this (if anything beyond “just cause I can”) 😊
Is this taking power from pcie slot? how about add 1 more choices with sata power instead?
Initially I though this is for people that is running out of fan header on their mother board, but I guess adding a fan into your pcie slot might have some use as well.
China line assembly in his home. Amazing.
Neat, I'm just wondering if it is possible to have fan speed control via PCIe using software on the pc like speedfan. Or maybe have it temperature controlled using the micro and a thermistor.
Just some ideas.
Would like to see how you made and programmed your programming rig
How about rack mount cooling fan with controller ?
a small suggestion use good looking button
It's really cool product, but at the same time hard to justify spending $80 on a fan, considering how low airflow an 80mm fan provides and how much more effective other airflow approaches will be in most situations. Anyone wondering if they should go normal or slim size fan should take into account that regular thickness fan will usually provide higher static pressure than slim fans, which is something you will need in a situation where you'd consider sacrificing a PCIe lane to a fan for airflow.
As a random challenge from a random viewer, make a version with ARGB support!
you should really consider 2-3 fan models with eventual internal usb header connection to adjust the fan speed from the computer itself.
WOW!
Great idea and insane work.
Do you have some test results? I'm interested how this performs.
its very cool i just don't see the fan doing much maybe movie air in the case but for a gpu it would already be doing this ?
That scraper is going to get dull extremely fast. Fiberglass is really hard
Is it able to handle 12V/1A fan?
If yes, then it would be perfect to cooling my U.2 cage, as it sits exactly next to free PCIe in my NAS whitebox
