Planning my video loop looking for suggestions

[evilsponge]

Hello all,

I'm currently in the planing stages of my video loop for my water project. I'm looking to water cool a single Nvidia 8800 GTX. I'm not a big fan of full cover water blocks so I'm looking at the following:
Swiftech MCW60-R VGA cooler - Rev 2
Then I guess I need a ram sink kit for the other chips
D-Tek FuZion GFX 2
I think they have a full cover piece for the other chips
Please let me know if folks here know about issues with these to blocks or have suggestions for something better.

Thanks!,
-sponge:D

VRAM doesn't need to be watercooled, neither does the NIVO chip. Enzotech sinks are your friend.

I have to say, to make sure u cool everything correctly i like the FC block, and the ones i have on my 8800GTXs are EK and they are superb, i can't fault them

[whe3ls]

you could go with either block you said with a unisink

[BlueAqua]

If you're looking for a gpu only solution I'd go with either the Swiftech or Fuzion GPU blocks along with a unisink like this:

My problem with the EK full cover is it s a one card kind of block where the others can be moved to different cards down the road. Don't get me wrong I'm a total ek whore LOL
Thanks for the help guys

Sponge... Go with a EK Nickel FC Block...:up:

:shrug::shrug::shrug:


Back to the original question by the OP. I gather you're going to be running a seperate loop for the GPU's...I can only echo/+1 BlueAqua's recommendation below. I couldn't choose between either the D-Tek or the MCW myself, so I am in a holding pattern on getting my GPU's under water.

I'm with ya man. That is why I'm doing the research now as I gather the parts for my video loop. The MCR220 is on it's way :D

How many GPU's in the one loop?

[evilsponge]

For now I gpu 8800gtx eventually I may move to crosfired Radeon HD 4850 512MB 256-bit GDDR3

Well, either choice would be fine in a dual block loop. We do not have any restriction numbers to use for the D-Tek, but we know the MCW60 is tried and true. I cannot say this with absolute certainty, but the D-Tek does appear to be more restrictive. By the way, which pump did you plan on using?

So at this point, I would say go with whichever one looks better to you or which one is easily available. The costs are very close. Personally, I was leaning towards the D-Tek before I called off my search. I've had great results with both of their CPU blocks...but the same goes for Swiftech.

Not much help in deciding am I? :D

[evilsponge]

LOL well I plan on using a MCP355 with XSPC res/top my only concern is if a MCR220 is enough rad for crossfire may need to look at a better rad well see my space requirments only allow for 2x120mm foot print

-sponge

Well, the 4850's look to be 200+ watt in heat load each (quick google search, so this might be wrong, but for the matter at hand lets assume ~200w). I am not certain on what the heat dissaption is for an MCR220, I haven't run the tests myself.

You can use a 220, but the air/water delta will be higher, meaning your temps will be higher than using a 320. Be aware that your temps will be higher as a result of the rad not being able to efficiently dissapate the entire heat load produced by the 4850's in CF. Its a trade off...clean fit of the 220 vs. higher temps on your cards. The decision is yours to make.


edit: if anyone has the actual heat load numbers for the 4850...that would be great! 200w per card doesn't seem right to me.

pish...

You see this guy:

i have her on a MCR220 with jab-tech orange slow speed yates.

@ 26.5C Ambients it holds my water temp at 30-31C, which is aiight for gpu loop.

Load temps shown:

so pish, anyone that tells you a mcr220 cant do xfire unless there xfiring 2 hd4870x2 is smoking crack and i want some. j/k!

[skinnee]

Well...there ya go sponge.

[evilsponge]

LOL Neakuh to the rescue should have known that guy has everything very sick setup guy :D well that ends that. Ok the plan goes forward now the question which one D-Tek or Swiftech hmmm......

BTW thanks for the research numbers skinnee! much appreciated. We need silver plated stuff! soon!

-sponge

[skinnee]

No problem...I'd still like to know your temps once you get going. I still have a sneaky suspicion that NaeKuh has something else involved... :shrug:

pictures tell it all...ram sinks are hot but i put some fans on my motherboard to keep it cool...

hope this helps

disregarding hearing 6 fans on mcr320

heheh

I already got silver in my loop


No problem...I'd still like to know your temps once you get going. I still have a sneaky suspicion that NaeKuh has something else involved... :shrug:

nope.

My GPU loop is as simple as it can get. Shortest tube length possible. Loop order is:

DDC-3.2 -> GPU -> MCR220 -> EK Xres -> Repeat.

SHORT TUBE LENGTH IS KEY!! And i have Koolance QD to kill my flow on top yet i still pull decient temps for gpu. :D

[evilsponge]

Why are there two GPU temperatures?

40c and 28.5c

LOL Neakuh that's one hunk of silver in that res you could kill a werewolf with that! I'm limited with my XSPC/res/top does not come apart

-sponge

[Hondacity]

one is for the gpu core and the other is the gpu diode...

[evilsponge]

Gonna assume the higher temperature is the core then? and thanks for the info.

-sponge

[Pedalmonkey]

NaeKuh's temps have 2 GPU temps cause its a the 4870X2 model so 2 GPU cores

[Utnorris]

FYI, I run 2 x HD4850's with a MCP355 and XSPC Res top. I use a MCR220 with San Ace fans. My temps are 33-37c (idle to load) with ambients at 27c. WB are MCW60's with Zalman memory sinks.

Hope that helps.
