I own a few of their other sizes. They're good fans but kind of thick.

Looks like I might have to go with an 80mm fan. Seems to be the largest size I can find at 10mm thick. Was hoping I missed something.

Thanks!

 

Wouldn't it be easier to just grab a standard 140mm fan and wire it yourself for USB? Get a high RPM one you know that can run on 5v and ezpz.

 

Yeah might have more luck finding a normal low profile 140mm fan. I'll dig around for one. See what I can come up with.

 

Np got a few 120s in my AV cabinet very nice was thinking same thing for labtop cooler lol just not the wood I'd get off shelf replace with these lol.

Yeah I have a 120 and 80mm. One of them is in my AV cabinet and the other one is around here somewhere. Very nice build quality.

 

Never seen a 140mm even 120mm 10mm height fan. All the laptop pads/coolers use 2x80mm low profile 5V fans. Or something close to it. These low profile fans are often pretty crappy. If you can fit 25-30mm height then get a standard high speed 1350-1700rpm 140mm fan and run it at 5V, many will start around 4V I think, gotta check the specific fan though when it starts up.

 

The standard fan thickness is much thicker then 3/4" plywood.

I plan on routing out a spot to mount the fan. I could have the fan a little proud on the bottom though I'd like to keep it flush if possible.

For the task I don't think it needs to move a ton of air. Main reason for wanting a 140mm fan was just to have a large fan running at low rpm.

Once I get the laptop in I can better plan the laptop cooler. I'll be able to see what height makes sense for any risers on the bottom and see what kind of fan thickness I can fit in. There are 15mm 120mm fans I'm seeing which might have to do.


Here are two 120mm 15mm fans I'm looking at,

Noctua (1850 rpm)

Or,

SilverStone (1500 rpm)
https://www.amazon.com/SilverStone-...SilverStone-Technology-SST-FN124-Design-3-Pins/dp/B07P989QSM/ref=dp_ob_title_ce

15mm is a little thicker then I'd like but it should work. I'll leave them a little proud on the bottom to give myself more meat to mount them to but they should work.

I found this to converter 5v power to a 12v fan,

Looks about right?

 

Scythe Slip Stream 120mm x 12mm

800rpm SY1212SL12SL
1,200rpm SY1212SL12L
1,600rpm SY1212SL12M
2,000rpm SY1212SL12H

Prolimatech Ultra Sleek Vortex 140mm x 15mm

 

Thanks.

I can't find the Scythe Slip Streams available for sale.

The problem with the Prolimatech is it's an odd shape. I should of mentioned it but I need it to be the shape of a normal fan so I can easily rout out a spot for it. Last thing I want is my routing to look sloppy.

 

Noctua NF-A9x14 PWM is 92x92x14 https://noctua.at/en/nf-a9x14-pwm




Thermalright have a 13mm thick 140mm fan, but it's not a square housing and only the red/black is available as an accessory. They are included with AXP coolers. As good as they are, 25mm thick fans flow much more air over entire speed range.

Scythe has 12mm thick fan

If your clearances are so close you can't fit a thicker fan, how much room is there in front of fan for it to draw air from? Fans need at least about 25mm to draw air into themselve, even that spacing limits airflow some.

 

Not sure about the clearance. I'm thinking it's going to be pretty close for it to work. I wouldn't want it to be much taller then a normal laptop cooler.

 

Noctua and a small number of other fan makers, have a supply of 5volt fans.


You could grab one of those and use an old phone charger and wire it up.


Could even find a USB extension cable and use that to prevent the need to modifying an old charger

 

You know you could just buy the whole laptop cooler in aluminum for $20 instead of spending $20 on a fan alone and then having to route and cut some crappy plywood? Why reinvent the wheel if you plan on making it square. If you're not getting better performance with a custom solution, why bother.

 

The laptop cooler wouldn't be square. It would be shaped to the laptop. The fan mounting location would be routed square since fans are square. It's also easy to set up a jig for routing out straight lines.

The main point of doing it is because I think it would come out nice and be a fun build if I can get the right fan.

Here's an example of the wood I'll be using. I made a K-cup holder for work. Should make for a fairly attractive laptop pad once done.

 

The step up converter would be a good idea because it would allow any 12 volt fan to work.

You can also buy those with variable voltage as well to get just as much fan speed as you need(useful for fans that do not start on 5 volts).

I have some from ebay that have a micro usb port onboard. I just added an extra output capacitor and fan header to it.

I have one of the slim scythe fans(1200 rpm model). it is quiet, but not very powerful(still worked on my cpu cooler for years when I needed a slim fan).

Post some pictures when you make your cooler.

 

Hey thanks.

I will. Thinking I'm just going to use a 120mm usb fan I have here. It's thick but I think I can adjust for it with the angle of the cooler.

 

Or buy a laptop cooler with fans you want, unmount them and put them into your creation. If you need fans for laptop cooling, it's often time to change that laptop. These low profile fans... never heard a quiet one. Sometimes having the laptop elevated with breathing room under = the aluminum board is drilled etc. gives it enough room to breathe and suck in cooler air.

 

I thought about doing that.

It's a new laptop. I haven't received it yet. I plan on modding the tdp so I'll want extra cooling.

 

The fan from the Raijintek Pallas is quite thin at 13mm and is 140mm. You mght be able to run it at 5V, but not sure what kind of air it can push.

 

I just ordered a fan,

Noctua NF-A12x15 PWM, 120mmx15mm @ 1850 rpm
https://www.amazon.com/Noctua-NF-A12x15-PWM-Premium-Quality-Quiet/dp/B071W6HJP6

I picked up this to plug it into,
https://www.amazon.com/4-Pin-Sleeved-Power-Adapter-Cable/dp/B01LW50R03


I'll see how it goes. If it's too loud like this I'll pull the fan controller off one of my AC infinity fans and solder it on the Noctua. Would of really liked that Scythe Slip Stream but I'd prefer to order through amazon prime when possible. A 15mm thickness should still allow me to keep the cooler fairly sleek. Should get it all in Wednesday and the laptop should be in by Friday.

Basic plan is,

1. Copy outline of laptop onto plywood.
2. Cut plywood to size without rounding off edges (round off edges after all the routing and the such is done)
3. Find center of plywood by making a X across it with a straight edge
4. Route out fan shape to about 3/4 the depth of the plywood on bottom of plywood.
5. Route out hole from top of plywood for the air to pass through.
6. Drill out any mounting holes for fan.
7. Once all of that is done then I need to figure out how I'm going to do the feet. I'm leaning towards putting two strips, one in the front and one in the back cut to size and angle desired. Have to play with this some to figure out what will work best.
8. Shape the edges to fit the curves of the laptop. Round off the edges through sanding and get it ready for the finish.
9. Finish - Not sure if I'm going to go with danish oil or stain and some varnish.
10. Mount the fan, take care of wire management and add a filter if possible.

Think this should go pretty well. Hopefully I can get this made and keep it reasonably sleek.

At a guess it will run about 950rpm on 5v.

Just curious, but why did you buy a PWM fan when you are using voltage control?

 

I would not expect that fan to be pretty quiet on 5 volts.

If not, Just add a resistor instead of a controller unless you are after speed control.

You find a resistor for the fan the same way as an LED.

You need to know the current the fan draws(this changes with voltage so having a variable voltage power supply helps allot here) then the voltage to drop.

So if you want it to have 4.5 volts you would be dropping 0.5 volts. If I assume 50ma @ 4.5 volts.

v / a = resistance
0.5 / 0.05 = 10

If it is too weak(and quiet), you can get that 5 -> 12 volt converter.

 

Have the plywood routed out. Worked out well though my circle cutting jig just barely made it. I had to use a nail instead of a screw for the pivot it was so tight. I'm currently searching around for my 120mm filter. Had one around here though damned if I can find it. I'm hoping their will be enough clearance under the laptop for the filter.

*I don't know why the one photo is flipping around. It's not flipped around on my end. -_-

 

Looks good!

 

Thanks man!

I should of went with your idea of drilling smaller holes but I was worried about the fan being too weak to push through the holes. I'm also not an artistic so anything I'd of tried would be simple or look bad.

-------------------------

Well guys, it's finished. Went pretty well. Was able to keep it low profile. The vent hole didn't line up 100% where I wanted but is what it is. For the finish I made a diy danish oil which worked well. The laptop fits on the cooler perfectly though I'm currently letting the oil cure before putting it back on. Overall I'm happy with it. There are things I would change in the future but for today it came out well.

 

Chargeit,

Looks good.

 

Thanks!

It worked out well.
