Sorry, I promised sellotape - here it was:eek:

As I said, this was just a quick knock together to check it would actually handle the TDP of this card etc. and make sure the effort designing and prototyping a cooler was worth it.

Ok, so its as quick as that (10 minutes), shut down, remove GPU (remove PC from top of printer!) remove cooler extension, apply super glue, fix in place, photo, reinstall, reboot, google apps already uploaded the images!

This is what I call, ultra RAPID prototyping!!! If your paying attention to when I posted all these updates, its all done in about 24hrs so far (minus 12hrs at work, and 7 sleeping)


....... here she is.

Benchmarks incoming, I'll update this post but right away, she's idling at 41, and it was mid 30's before (could have just been residual heat in the case as its been benching continuously in the background the whole time I've been posting/designing and updating my excel results etc.

Update, I made some extra notes on core speed and voltage, it seems to get higher and higher (maybe case temps are dropping slowly from the last round of benches without the extension)

V1 Full refers to Version 1 (full cooler, ie within the extra bit stuck on!)

Unigine Valley Benchmark 1.0 Extreme (windowed, 1600x900, Ultra, 8xAA, D3D11) i5-4590 3292MHz x4

FPS Score MIN MAX temp fan
v1 full run1 26.7 1118 15.4 47.9 80 60 Case Closed 1045-1070mhz boost 1.062-1.087vcore
v1 full run2 26.8 1122 15.9 47.8 80 60 Case Closed 1058-1070mhz boost 1.075-1.087
v1 full run3 26.8 1121 16.1 47.5 80 60 Case Closed 1058-1097mhz boost 1.075-1.100

So, it's all looking good, I'm going to run it for a while now and get some hours on this card - enough playing with it, time to play on it! (actually after one more bench with 100% fan.......)

So, with fans on full, and given plenty of time to get up to temperature and settled...... it runs at 80c still. This is obviously just the temp that is being targeted by the boost. Core voltage and boost speeds were all much higher than previously. This tells me that if I can get more airflow, it will run faster - so I'll have to see about trying a 50mm fan, or dual 40's or perhaps just getting a branded fan (although the one that's in is actually very nice, with nicely designed blades, its very very quiet and produces a good solid pressure - shame theres no brand on it at all!)

I did progressively get a lower and lower score, so this isn't completely sustainable during 100% continuous load.

It actually ran a bit quicker, and was generally benching better all over. I had the intake fan, CPU fan and GPU fan all on 100%.

I could see the new image links weren't working when I logged on from another PC, hopefully its sorted but I don't know what I'm doing here!

Can anyone recommend a free image host, google doesn't seem to be working out and my 10+ year old imageshack account turned out not to be "free forever" lol

That shroud looks really awesome. This is exactly the sort of thing I'd want a 3D printer for!

The only negative I can see is that because of the single-half-height bracket at the end, there's nowhere for the hot air to actually get exhausted. What about swapping the fan direction and having the front case fan exhausting too?

kaku, there is actually a tiny vented area :D its less that 1/2 the width of an actual slot - so the air being ducted down there is actually getting vented out the back of the case!

I've got a pair of Yate Loon 50x20 blowers, and knocked up a cooler design last night, its printing now although it may fail as its tricky to print - time will tell. I'm at work, the Robox it printing it at home - I'm thinking of getting an IP cam so I can keep an eye on it :p - I might put a request in to CEL (the manufacturer) that they add IP camera and remote kill switches to the software (they've already added GoPro compatibility so the machine moves out the way every so often, takes a frame for the time elapse and then continues printing :D)

Just dropping by to say what a cool little project this is! Thoroughly enjoying your updates :)

Thanks very much, its nice to know its worthwhile posting :)

So, it printed, its bloody rough, but it printed. I'm going to have to work on making the design more suitable for a FFF printer but for now, results are looking good. Temperature wise, the fan profile is still targeting 60% and 80°C but clocks and core voltage are up on the V1 design. The fan was even backing off a little at times - its obviously providing a bit more oomph than that 40x20.

Kaku, here are the little vents between the card and the PSU - this is why my title says single slot "ish" as I have a tiny bit of extra head room, but no doubt most cases do otherwise face mounted fans would be blocked! - It kicks quite a lot of heat out of those holes and its something I can improve on by opening up the holes in to a single slot and/or sealing the cooler better so it has more pressure to push out the heat and less heat leaking back in to the case.

And here's version 3 with the 50x20 yate loon

What a fantastic little project.

One of the first things I have seen a 3d printer used for that really was worth the time and effort.

A little late to the party, but subbed :)

This looks ace. Could you get a bit more cleareance for the GPU cooler by stripping out some of the PSU casing in the area directly above it? Or maybe even fashioning a joint PSU/GPU shroud with the 3d printer, giving more airflow for both components?

Really awesome!
Calibre41 do you have any feedback on your configuration since your 3-month-old post? (this computer isn't supposed de get such a card as a GTX 750 Ti)
By any luck, did you share your work on some 3D printing sheets website? I am really interested in doing the same (i own the same computer and MSI card :) )

Guys, sorry, I didn't get any email notifications, so I didn't see these messages!

She's still running really really well, temps are fantastic, it's running cool and quiet, I couldn't ask for more really, it will actually run cooler and quieter than stock - winner.

Deed, where abouts are you located, I could print you one on the cheap.

So, who wants to see a GTX 1050ti version? - I've scoped it out, they all seem to have the dvi mounted over the dport/hdmi in dual slot config, so I'll have to cut it off, those of a nervous disposition might want to look away! With the 750ti everything remained stock, no mods etc, so it can be returned to stock.

Any how, that's all for now.

I wanted to try and keep things stock so they're just bolt on upgrades, but I must admit, it's a solid idea and probably more achievable to most without access to cheap 3d printing. I would guess they might be able to run stock dual slot low profile cards with a PSU cut if the PSU's PCB is mounted on the other side (which it looks from my photos like it is) and also, if there are no bits in the way inside. Room would also have to be made for the dual slot IO plate on these newer cars.
