Tesla M2090

[Psi*]

I haven't started it yet.

I have searched the net trying to find someone as adventurous, but there doesn't seem to be anyone. At the first break I have toward the end of the month I will take the heat sink off 1 card & figure out how to make a 1:1 image/drawing of the board & mounting holes. I'll send that out to see if someone will give an educated guess that a GTX580 water block will fit. Maybe to frozenCPU for instance.

Great. Please can you let me know how it turns out?

I ended up here because I couldn't find anyone else this adventurous either...

[DarkStarr]

Just post the bare card on here and we can compare to a ref 580. If its the same it should fit.

I'm also taking the M2090 plunge. Thanks for the details; very informative. Think I will stick with air cooler, fan in the middle, blow straight in with vents on either end. I think one would be bold to discard the nice stock vent setup, unless space is an issue, as one should be able to achieve airflow equal to or exceeding the server setup quite easily. See you on the other side.

I'm at a loss as to why NVIDIA doesn't bundle a more efficient cooler than it does on these things, if many people are willing to go to extra lengths just to keep it cooler.

I guess they expect all of these to be used in jet-engine server rooms.

I am interested in what you end up with. Pics when you can

Looks like the server setup is just some little fans on one end that blow longitudinally through the fins. So put a plate over the fins that extends beyond the end of the card, and mount some fans on that with glue or whatever. Here is the server setup:

Seems like two of these should work:

Not sure how to get the plate to stick to the fins, but perhaps there is some kind of thermally conductive double sided tape or glue/paste. I would probably just glue the fans to the plate overhang, or bend the aluminum into an L shape and bolt them on. Agricultural, to be sure, but should be effective and relatively compact. Will post photos when I tear into it.

The problem with that is the 6-pin fan connector. I have no idea how that would be hooked up inside an ATX system. A brief search doesn't show up any adapters or add-on cards.

I thought about adding fans + a shield across the top. I have a Lian Li case with a squirrel cage blower & considered adding one of those to the end ... with a shield across the top. The blower would not have to be inside the case but could be outside pushing air in. Last could be a couple of 60 mm fans added to & pushing air into the fins.

I decided I didn't like any of those. Although I took the heat sink + heat spreader off this M2090, I think better would have been to keep the heat spreader on & just replace the heat pipe with the water block. The heat pipe heatsink is just for the GPU & fits thru a square opening in the heat spreader. The front/back heat spreader is pressed against the memory chips with thick heat tape & voltage regulators with a thick rubbery like TIM. It will be a bit challenging finding the right stuff to put in their place. Obviously Nvidia was not too concerned with conducting a lot of heat off those devices.

I haven't received the water block as yet to check fit. But I am hoping that it will fit thru the cutout in the heat spreader onto the GPU. The C2070 I have is substantially overclocked & can run at 50% to >90% for many hours. In another thread I have discussed that and I would prefer a similar setup but don't see it happening. Sooo this is why I am looking to water cool this card. I think the external radiator will be much easier to blow the dirt out of ...

[atypicalguy]

In that case, I would think any GPU cooler configured for a higher end NVIDIA board would work, e.g.

Not as elegant as water, but it is probably a bit easier to get up and running in my case.

How does one remove the existing fin assembly (I assume this is what is meant by "pipe") to expose the gpu and attach the new block (of whatever cooler)?

Thanks,
Karl

I -think- that cooler would work no problem, but I can't say for sure; the schematics would need to be looked at. I can see water being easier to install since it's just a block, and little heatsinks can be used for the GDDR, but a full cooler like that might be iffy. It does seem to be raised all around the core, but I can't tell for sure from the pictures shown.

I talked to one of the cooler guys at the website store. He said he woukd probably stick with existing heat sink/fins and put a pwm fan on it. Looks like the fin planform short axis is about 8cm; could go with two 70mm on the side or one of these (non pwm) blowers on the end: http://www.coolerguys.com/840556094272.html

I need to take a look at case space when I get home. He was not sure about whether the full setup I mentioned above would fit. Probably just run pwm fan mounting screws right between the fins. Anyway a $30 solution, or less, either way.

From a countercurrent thermal exchange standpoint it is probably best to suck from directly over the gpu with inlets at ends.

[Rob Williams]

Hmm, that's an interesting idea. I actually thought of hooking something like a Delta fan to the end and controlling it with a fan controller, but that solution is much more elegant. The 17 CFM rating kind of seems small, but I guess this is a concentrated area, so it should be quite effective - and if so, that's one hell of an inexpensive solution.

[atypicalguy]

FYI this one has PWM control/ 4 pin plug:

http://www.abmx.com/4pin-pwm-blower-...-server-models

It says 97"cm" but that would be kind of big and would not fit into a server, so I think it is a typo and they mean "mm". Power at 1.5A 12V seems like it might not drive a 1meter fan either...

cheaper here: http://www.provantage.com/supermicro...4~7SUPM3T8.htm

And on the small format axial fans, this one is loud (59dB-louder than a quiet vacuum cleaner), but 4-pin, rated at 2.61" static pressure (I think this is why they like these counterrotating fans in servers):

The blower above is only 28dB. Options here:
