SFF GTX 750 ti, low profile, single (ish) slot mod

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.

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?

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.
 
bat09, andreyu30 SOOOO sorry, ive not been getting notification through!!!!

The MSI gtx 1050ti is WAY WAY WAY longer than their 750 and its a different cooler so my cooler won't really fit!

** No Trading outside of the MM ** and grabbing a 6gb 1060 which is roughly 3 times quicker than the 750ti and only about £75 more than a low profile 1050ti - I happen to have a load of liquid cooling kit that was destined for this SFF case, but also - it is no more, SFF just doesn't hit the specs I need, as convenient as she is! The bottom drawer of my desk is a filing cabinet type with hanging rails running right to left, and a secret compartment at the back, its 305 wide, 260 tall, and a whopping 630 deep (its a bloody big drawer!) so I'm planning on going for a bespoke PC installed in the back of the drawer, liquid cooled. I'll make up the frame for the mobo, psu 3.5, 5.25 and IO etc from an old lian-li PC60 thats in my loft.

I did look into the 1050ti mod in great detail, it seems like the best option is the Zotac, since the MSI is WAY too long for the "wrap around" fan idea which works so well - the 750ti is around 146mm, the 1050 is 182mm - what the hell were they thinking!

The Zotac seems features a similar flat top cooler design - excellent for my kinda mod! It even has a channel grooved out along the top, which means I could shorten and thicken the sides and more easily mount the cooler. - the only thing is, it has a large gap between stock fans and cooler fins - it works presumably to allow the air flow from the fan to more evenly distribute itself across the cooler to prevent dead spots - but I just want maximum cooler area! I would have to make the shroud wrap down and touch the tops of the cooler fins inside, since I want all my air to travel the full length. Also, I note the base is quite thick, this would be ideal to machine and solder a flat heat pipe assembly, or even just a copper block into the base which would massively increase performance (since copper transfers double the heat of aluminium)

The gigabyte is around the same length as the Zotac, and more readily available at this time (I think the Zotac has perhaps just launched?) - so.... I was going to go for the Gigabyte and just machine the cooler down to the max height I can work with and then solder a copper sheet top on to it (I have a proper machine shop at home - who doesn't!?) and at the same time, I would measure the cooler underside clearances, so I could perhaps CNC one from copper cooler stock - yep, also have a CNC mill at home.... who doesn't.... maybe not many actually....

Since they mounted the DVI over the HDMI (dicks!) I have to irreversibly mod whatever card I buy anyway - so hell, why not cut up the cooler while I'm at it! My MSI as it stands is easily reverted back to its full factory cooler, its a true bolt on mod.

So the plan was just that, Gigabyte 1050 ti + machine down, + solder a copper sheet top on, and then 3d print a wrap around fan design again. But now moving away from SFF however if anyone fancies volunteering a card be it MSI/Gigabyte/Zotac, I'll get the mod done, donations welcome - hey you could even let me keep the card, I don't mind :D.


Over and out....

This is an IPT, not sure which as it’s been years sorry guys! probably drawn in Inventor 2011 or 2015 at a guess, any later version should open it. It includes both halves, there’s an extruded block subtract that I flip to give me each half.

This is the STL ^

This I guess is the straight fan version.

Sorry it’s been so long, have since had 2 kids and i’m getting ready to move house! great to see all the other similar mods.

Sold the desktop when baby #2 was ok the way as the office was to become his room! (the Pc grew from this SFF to a full blow 8 core i7, GTX 1080ti with a full blown custom cooling loop 2k 144hz monitor etc etc - the big PC bug bites hard!!!)

Been running a very impressive Lenovo Y540 i5-9300h undervolted with a GTX 1660ti also undervolted, with liquid metal TIM, 144hz FHD display, really impressed it’ll run many demanding games with a frame rate cap when i’m in the living room without even spinning up the fans, and thus have just ordered the new 16” 16:10 165hz 2560x1600 laptop from lenovo, 8 core 16 thread Ryzen 7 5800H & RTX 3070! - I don’t think this will be capable of gaming silently on the sofa!!! Est delivery 12 weeks!
