Looks like the 5870's gpu core size is much smaller than the GTX 280 I have here... It'll definitely fit the evap's head better than the 280...
Would it be bad to use it on a bigger core with such a small tip? I wouldn't think it would take the heat off of the whole chip as well...

I got it for pretty much the same reason as my cascade unit... Ease of use when benching for long periods of time and the lack of the constant supply replenishment that you have with ln2 and dice. ;)
I can take my time and tweak my clocks and odes for hours without really wasting anything...
Also this seems to be the better option for me because I'm still 15 and don't have a drivers liscense to run out and get ln2 or dice every few days... :rofl

Shooting for 1100+ core on the 5870 if this performs ok. The card does 1066/1330 through all of the 3d marks on the stock cooler at 1.35vcore...
I'll be sure to get the temps of the card in while idle@stock and then monitor the max while@load overclocked and bolted in one of the 3dmarks(probably a vantage gpu run).

I hope this testing will make it clear whether it's worth it (how much difference it makes)to add a rad and a gpu waterblock to your loop or to get an low end ~$300 SS unit that holds decent temps.
Thanks for all the interest! :)

I don't think you'll have any problems with the smaller evap head on the bigger ihs. If you look at the ln2 gpu pots in some cases its the same disparity but still the ihs gets plenty cold lubbin.

Cascade and phase on the gpu= no excuses! :keeporder:

So no pressure but dammit man, we'd better see some ownage clock for clock ;) :laughing:

I have a Chilly1 here that I havent used in ages and ave thought about doing this. Only problem is has the standard evap enclosure and I havent spent to the time to mod it to fit a GPU.

I expect it should work fine tho.

I have a round of new tests coming up soon that I will use it with, not related to GPU's tho., then I don't know what I will end up doing with it.

Yo bro seen plenty of mods out there as long as you only have one card a standard straight evap. will work fine with som field alterations for the bolt paterns..... LOL

Interested to see how this holds up. Would think older SS might be okay for some older cards, not sure of the top of my head where 5870 fall in TDP land, hte 5970 was tapped at up to 300W though yes? So I imagine a solid 200W load is doable on the 5870. Yikes!

also I know the same as a cascade, you have very little mass transfering the cold on the evap compared to a giant block of some sort with dice/ln2

Got it mounted and booted it up... Gpuz and afterburner showed temps in the -40s. Saw it go down to -49*C.
I thinking need to insulate the card from the condensation or I might have problems... It'll drip otherwise when loaded.
What should I do to protect the card? Use eraser like on my motherboard?

erasure for sure. Looks like a decent unit LF.

Also need to protect the motherboard by the card as well. Gravity is a bitch

Got it insulated, movbo top... Here goes!
Thinking about making an upside down rack... :confused:

I was dicing a card a few weeks ago

eraser the front and we used sill sealer on the back and tapped it on.

put a slice as long as the PCIE in a sham wow and stick the card trough it
it shold be tight to the interface

Not a drop

Teh Sex

Lol I put too much eraser on the card myount isn't tight enough and is running -1c idle......... Time to redo ;)
