Tesla P40 Radial fan shroud

*** ADDENDUM: Guys, c'mon. Somebody please react. If you made this work tell me so. Otherwise I have to conclude it doesn't work and I'll pull it off thingiverse. All I asked is to give back to the community and me by shooting a picture. I'm pretty sure a lot of people post what they ate this morning, or the colour of their shit so please, make some small effort. I ask for _one_ reply*** ***Please post a Make (Photos) if you made this Thing happen and are pleased with the result (would make me happy to know). Please Report back if it didn't work for you. I want to make this work.*** Hey, This is a fan shroud for Nvidia Tesla cards which are structurally identical to the P40. After a failed attempt using a normal Noctua (damn I sank money into it...) fan I realized that air pressure is the key to cooling the P40. Due to construction radial fans can build up pressure, cause of centrifugal forces air can't escape back. The noise level is more bearable, the sound pitch is different to axial fans, but thats a matter of taste. This design is quite over engineered, but after trying a few on thingiverse and facepalming in sync, I had to design it myself. To try out if the fan is the right one to chose, I just used ducttape,- to my surprise this worked well since the opening of the fan I have chosen is approximately the same to the Tesla P40. And thats why its called duct tape. After extensively usage I can report that this design works for my needs and so it will for yours, I anticipate. Please do consider to post a Make.- report back if it worked for you. Since I made this to solve a problem people might have, I would appreciate to know, if it actually got it's use. I poured a few days into this. BOM: The fan I have used is: AVC BAZA1022R2U 12 v **Take care that your motherboard can provide the current**,- it SHOULD See pictures, it was reasonably cheap (got it for 15 Euro, you find it for double price also.) Since its a fan for notebooks, I suppose, you will need to **crimp a new connector** to it, so it fits a normal motherboard header. I used a JST-SM connector and trimmed it a bit with a nailclipper. But you can get an according connector also The screws are: 4x M3.35 + nuts 3x M3.12 (you can use longer, since it just screws deeper into the tesla. but take care) Temps: If I have the card under full load for two hours I reach sweet 69C under full Fan speed on nvtop. The bottom plate of the P40 which is the heatsink for the memory chips gets VERY hot since the button plate does not get cooled with a fan blowing through the nvidia tesla. I will get a copper heatsink I mount on it (might be reasonable to take off the plate at all and let the chips cool on air). In my PC I use the CPU fans to cool the bottom plate, I connected one fan to the peripherals header, so it reacts to I/O requests. Regarding Printing: - Turn the upper halve 180. - You will *need Support* for the part that shoves into the Tesla.- this is necessary so air doesn't leak. Interface to support doesn't have to be beautiful, but must be tidy for snug fit. - I used Ironing for better airflow. - I used PETG, but PLA should be possible aswell. - dry your filament to prevent stringing! - Use heat gun to remove stringing - You dont want to get filament particles into the tesla where they bake into it.
