Cooling an unusual video card, advice appreciated

[A_Rabid_Toaster]

Right lads, first post here. I have a rather unique situation I'm hoping you can help.
My System is a pre-built (of a sort) a Dell Precision T7610
The cooling for the dual Xeons is fine, but my GFX card, an AMD Radeon Pro WX 7100 leaves much to be desired.

My system is a workstation (I am a fetish photographer) and only very occasionally will I game, and those games that I do play tend to be simplistic stuff like Armoured Warfare, or Minecraft.
But even at modest settings, the GPU will quickly hit 90C, which I feel is unacceptable. Idle is around 45C (there is a custom fan curve set in the Radeon Pro software, but the fan curve tops out at 4500RPM)
There is very little space for a custom loop, and I"d rather not step into that minefield if I can at all help it.

I was thinking an AIO, but either one doesn't exist for the card, or my searching skills leave something to be desired.

The card is a single slot and I"d prefer not to have the eat up more than one more slot, as the PCI slot (yes, PCI) at the bottom has a firewire card which gets some use.
A rather stupidly large side view of a system like mine can be viewed here:

There is some space behind the 2nd CPU for a fan/radiator combo possibly, the gap is about 44mm (take or give, it's difficult to get an accurate measurement) with perhaps a 89mmx102mm (X axis by Y axis) area for the fan/rad combo.

I know this will present a challenge, but I've heard tell you guys are the best forum to present this sort of thing to, so...here it is.
I am open to alternate ideas if an AIO proves to be unfeasible.

Cheers!

I'm not able to assist, unfortunately, but your image link doesn't work. I'd suggest hosting it on Overclockers rather than just posting an external link.

Whoops, let me try to post it here
The image is not my system, but it should show the space I have to work with

I just skimmed the following article but it seems to suggest that by updating the firmware, you could reduce the temps. https://www.tomshardware.com/reviews/amd-radeon-pro-wx-7100,4896-5.html
While the article is about 4 years old, if you've never done it, it could help.

If that works, it would make the cooling question moot.

I too have seen that, and my video card seems to have the updated firmware on it, as far as I could tell from the Radeon Pro software. I had considered re-flashing the firmware, but I have not actually found a proper link to download from.

My best suggestion is better case ventilation if you haven't been able to find a way to mount an AIO. (zip ties, maybe??) Those single-slot coolers are just going to be terrible no matter what you do though, honestly.

 

[A_Rabid_Toaster]

I run without the side panel on, just for general purposes. Air flow is pretty well thought out, in my opinion. Three front fans blowing air across the RAM (in slotted covers), and the video card section, as well as one blowing across the top PCIe slot, and on the other side of the case (the bottom of where the mobo is) are additional fans for the SAS drives.

I was pondering, though I have no experience with them, something like a PCIe powered dual slot fan, that would blow across the GPU. The trick here is it would have to be powered by the PCIe slot, as there are no sata or molex connectors (an interesting quick of the Precision line.)

 

[don256us]

Ahhhh.... No! I would not recommend a fan on the PCIe bus. Just seems like asking for big trouble. I would be more comfortable with a SATA Y-cable or Molex Y. My first choice would be to use a Molex if you have it. Split it and connect your AIO/fans. I feel like the power flowing through the fan/AIO would be too dirty to have going through the PCIe slot. That's just way outside my comfort level.

What I don't know is if my fears are warranted or if the facts corroborate my fears.

Another thought with an AIO is (if you're up to a slight challenge, and I think you are) to look at mounting the AIO radiator outside of the case.

You could also take power from the 6-pin PCIe pigtail connector. https://www.newegg.com/p/pl?d=6+pin+to+molex https://www.newegg.com/p/pl?d=sata+power+cable+6+pin.

If you're already operating with the side panel off, box fan is always an option, although inelegant. The CPUs may do better with the panel on as it seems like they rely on airflow from the front fans.

Have you tried to disassemble and clean the GPU cooler out? It could be choked with dust.

In terms of mounting an AIO, I doubt it will fit in a single slot profile, unless you have one in mind that is that thin on the block. The first step would be to measure the mounting hole distance of the stock cooler (the somewhat star shaped silver colored spring retainer with 4 black screws on each point is what you want to measure). Then you can see how close you are to something else out there like the common Intel mounting holes.

There is a little dust, I keep my system well off the floor. There are a number of GPU-specific AIO units, but nothing that specifically says it works with the WX 7100, so there may have to be some fiddling with shims or something. I was rather hoping for a pre-fabbed unit made directly for the WX 7100, but that is asking for rather much I fear.

There is this nifty little device here: https://www.amazon.com/NZXT-Kraken-G12-Mounting-Compatibility/dp/B06ZYHRMYP
Which seems to be the direction I'm going towards, unless anyone has any negative experiences with it.

 

[ATMINSIDE]

The Kraken works very well, honestly. Just double-check that it has the correct bolt patterns for you.
