Gpu Vram and VRM Heatsinks

[Adam Schneider]

I want to add some VRAM and VRM passive heatsinks to my gpu. Any suggestions? any particular sizes I should look for? Thanks in advanced

Is this accurate? Would need to know the exact model anyway.

GPU Type
NVIDIA GeForce GTX 780 Ti

yes I have a 780Ti. I was seeing you can get them sorta cheap now. Sow I was wanting to buy some heatsinks and set up a ghetto water cooling setup and SLi

Doesn't have to be ghetto. NZXT G10 Bracket is the cleanest way to slap a CPU closed loop cooler on there. If you do that, any heatsinks you want to pay for from places like frozencpu.com

Pretty sure you'll need 12 memory sinks though for a 780Ti. And looks like 6 VRM heatsinks. At least on a reference card. If you have an OEM custom PCB, then you will have to list the model.

Right but Ghetto is cooler in my opinion. What I am looking for is dimensions of the heat sinks so I can grab the right ones. Like what are common dimensions for the VRAM and VRM

Now that is a trickier question as memory module sizes tend to get smaller as process nodes are advanced. What they actually choose to put on a GPU in terms of GDDR5 is going to vary by memory vendor and OEM.

Which is why I have asked for the exact card to be able to give a more specific answer.

VGA memory heatsinks will certainly fit, as the spacing around memory modules is usually about the same on any given card. Those 14mm ones will probably be fine. They don't have to be an exact fit, you will be gluing them on with thermal adhesive.

Simplest method would be to take off the GPU cooler and check, plan out what you want to do, then reassemble it. You'll want to order some thermal compound, not to be confused with thermal adhesive, to reapply the heatsink ahead of time. That would be good practice if you haven't disassembled a GPU before.

Once you have the measurements and a plan, it shouldn't take long to select the parts.

I was figuring that I could get VRAM heatsink no problem. but VRM (Voltage Regulator Module) is the real important one. I was just wondering if anyone had some recommendations on heatsinks that may fit most reference cooled 7x0 and titan series GTX Nvidia Gpus VRM.

I would get a non-conductive thermal pad the rough size of those areas and apply a longer heatsink across all of them. I have glued across several ICs before with no issues, but most of the boards I have messed with already had VRM sinks installed.

Rough sizes for the red area (group of 4 ICs) 36mm x 12mm , same for the yellow area to the right.

75mm x 16mm for the green area.

I have posted this question multiple times, and you my friend are the only one who could answer it sufficently. Thanks.
