Customer heatsink v3. You guys have baller 3D printers now and you can afford metal filament to run through them. Design you a heatsink, print it up, send it in to be sintered/debinded and then run it through its paces. They make bronze, copper, aluminum, steel, etc. Try all of them! That's like a whole series. You could even 3d print the fan that goes onto these heatsinks. YOU COULD COOL THE WHOLE PC WITH 3D PRINTED PARTS!

FYI anyone curious on how this worked. It worked great. The PC has been running for about 6 months now and I've had no trouble with it. Don't let internet people tell you it cannot be done...especially if they can't tell you why it won't work.

Hello. I've got an HP Pavillion Desktop PC that has a proprietary motherboard and an underpowered PSU. I'd like to install a GTX 1070 in it but the existing PSU cannot power it. It neither has the wattage, nor the pins. I have a few PowerEdge 2950 servers with redundant Dell N750P-S0 750W PSUs and I'd like to modify one of those PSUs to power this GPU. I've found videos of people modifying these PSUs to charger 12V lipo batteries, and I'm wondering if It would be simple enough for me to take an 8pin EVGA power cable, wire the 12v leads and the ground leads to the appropriate terminals on the server PSU, and turn it on. I've searched and searched and haven't found any adapters or examples of anyone doing what I'm trying to do here, but there does seem to be a lot of folks using different models of server PSU to power mining rigs. I don't see anything wrong with this logic, but before I blow this GPU up due to an oversight, I thought I'd sanity check myself here. NOTE: I know this will be loud, I know it's not the most efficient solution, and I know there are cheapo power supplies I could buy if I just want to power this GPU. I've got this E-waste that I'd like to upcycle and this seems like as good a way to do it as any. Thanks everyone.

I don't see a place to post video ideas for the normal LTT channel, so I apologize if this is a faux pas. Can you do a video where you use literally every single pin/header on a motherboard and go over why each of them exist? I seem to never utilize 80% of those pins when doing new builds and not knowing why they're even there other than to stress me out and give me more options than I need. thanks!

So I was just thinking, it's going to be near impossible for me to 3d print at the level I'm going to need to make a proper mold for copper casting. Even if I did, that cast is going to need to be ON POINT and that may too prove impossible. What if Linus and the team designed their heatsink, sent it off to Shapeways, and they could actually print it in aluminum for them! I just checked it out, and it's no more expensive than half the stuff they already waste money. I think it's worth a shot!

Getting a Vega 64, but Need Guidance
Padenormous replied to Padenormous's topic in New Builds and Planning
That's what I'm doing here. Vega is new enough that there are only basic benchmark videos on YouTube and I haven't seen much else. Was hoping I'd run into someone on here who's used it for MeshMixer, Solidworks, etc. -

The 1080 seems to be the same price, but the 1080 is at least $150 more. -

@themctipers Thanks for the reply! I'm more interested in the compute power of Vega. I do some cad work and 3d modeling for 3d printing and figure this would be able to take larger files. -
Hey everyone, I've made a deal with a Craigslist seller to get a Vega 64 for $600. I've had my eye on this card for a minute now, but I'm concerned my rig might be too old to fully utilize it, but that might just be paranoia. My specs are as follows: Summary Operating System Windows 10 Pro 64-bit CPU Intel Core i7 4790S @ 3.20GHz 30 °C Haswell 22nm Technology RAM 32.0GB Dual-Channel DDR3 @ 799MHz (9-9-9-24) Motherboard Gigabyte Technology Co. Ltd. Z97X-Gaming 5 (SOCKET 0) 26 °C Graphics Standard Monitor (1920x1080@32Hz) Intel HD Graphics 4600 (Gigabyte) 2GB NVIDIA GeForce GTX 750ti (NVIDIA) 26 °C ForceWare version: 384.76 SLI Disabled Storage 232GB Samsung SSD 850 EVO 250GB (SSD) 31 °C 465GB Seagate ST9500420AS (SATA) 28 °C 465GB Hitachi HTS547550A9E384 (SATA) 25 °C 111GB KINGSTON SV300S37A120G (SSD) 25 °C Let me know if you think this rig can really utilize this Vega 64 properly. THANKS

@lsstefan I actually had a thought of making the copper look like a fire. Sounds lame, but I'm wondering if the shape of a flame has some thermal properties that maximize heat dissipation? I've done no research on this and I could be way off, but just brainstorming.

@bennyg1 I think you're right in that the black heatsink isn't going to do as much for me as adding fins/surface area, but black body radiation definitely isn't a myth. I agree that lots of thin fins and air blown across is effective, but their are thousands of other designs they could have gone for other than a simple block/fin setup and it would have been more interesting and potentially more efficient. I think I'll forgo the anodizing of the copper for a number of reasons, number one being that apparently you can't anodize pure copper. I do think I'll aim for a wider base base though.
-
Been watching some videos on heatsink design. Apparently if I can get the heatsink black, that will improve heat absorption and radiation as well. Apparently as width of the heatsink increases, heat disapation increased by a factor of 2. Hight only increases it by a factor of 1.4.
-
Honestly, having thought about it more that probably won't work right. The issue comes with the top half of the Pyramid, it's not going to have enough surface area contact with the bottom half to get a sufficient amount of heat drawn to it. Still contemplating. Maybe a cube variation? Also, I wouldn't mind adding some heat pipes, but I imagine that's going to add too much complexity.
-
Alright, after scrounging around my basement, I found about 3ft of 8awg copper wire and about 10 feet of copper pipe. I think I'm set on some free copper now. Next step is to work on the design of the heatsink. I'm considering something like a fractal pyramid.
