DDC Heat Dump

[zlojack]

I've been wracking my brain looking for some way to get some extra pressure and flow into my CPU loop and hopefully take more advantage of my EK Supreme.

Currently I am running it with an MCP655 (D5) at the highest setting.

The loop goes Pump>block>PA120.2>Res

Now before you tell me I need a bigger rad, I don't have space for one in my rig, so forget about it. Maybe down the road a bit I'll build in a bigger case, but for now the H2GO is it.

Now..before you get started Red, your Iwaki is awesome. As are your multiple 120.3s and your massive case. Too bad your balls fell off years ago :bird:

:D

So...I think I have figured out a way to get two DDCs into the space I have in the bottom of the case (pending testing, of course).

Would the increase in pressure/flow of two DDCs in series be offset by the heat dump in the loop?

Let me know your thoughts on this!

thanks!

I tried a single DDC (3.2) alone with a PA120.2, wrote down the temperatures and such under idle and load.

Then, simply added a second DDC (3.2) changing nothing else. The extra heat dump from the second pump basically voided any temperature gains (maybe 1°C better) from higher flow rate.

Also, with a CPU only loop that you have, you are already probably at the flat part of the curve for gains with flow rate and would see diminishing returns from higher flow. I do not have experience with the Supreme, but my testing was done with a STORM and is quite restrictive.

Only way to tell is try it! I think it would be worth a few hours of time or it will be nagging at you all the time, at least it would for me.

[zlojack]

Yeah...that's true.

The only thing is...I'd have to buy the two pumps.

So you think there would be little to no advantage over the current setup?

I'm sure getting a DDC with a good top will be a bit better than your D5 in terms of head pressure. Watercooling parts retain a good value so you won't lose too much for trying.

[Snyxxx]

Buying two pumps with tops is an expensive proposition at ~$200.00

Are your temps that bad to justify the expenditure.

I used to run a D5 on a STORM, PA120.2 and MCW60 GPU loop. I replaced it with a DDC-2 (more powerful than 3.2) and the difference was incredible for flow rate. I could tell by my reservoir - calm with D5 and violent with DDC-2.

I agree a DDC with top would be better than the D5, but at what cost.

[zlojack]

I'd probably use the DDCs down the road for a while. The question is: What about 2 of them?

My next build will involve a larger case with more options, but that's probably closer to the end of the year or early 2010.

I think I'll just leave it as is and upgrade the pumps when I move to the bigger case.

You'll always have use for pumps. Regardless of the heat dump, when dealing with DDCs, you will always need redundancy. This advice is dispense after having years of experience with Laing pumps. Not so much with D5s, but definitely with the DDC series if you are going to futts around with aftermarket pump tops. The extra head pressure is almost necessary with the EK Supreme you have. Heat dump is over rated. If the water does not flow well through your water block, the heat dump issue is inconsequential. The whole idea behind the H2Go case is not to have multiple independent loops. Notice the "Go" name, implying mobility.

[Ricey]

To address the space issue, you can get EK's, Watercool's or Alphacool's dual pump adapter. The contraption can be mounted in the 5.25 bay.

[zlojack]

Well, I think I've got the space thing figured out.

I would use the second chamber in my dual-chamber reservoir for my CPX-1 chipset/RAM loop and that should allow me the space necessary to install a DDC with XSPC reservoir top and a second DDC with an X-top or something like that.

I say "should" because until I try it, I don't know. If it doesn't fit, I'll put them away in their box and keep them for my next build.

I think your expectations are set a bit high for a mobile case with high end components inside.

I agree. :crack:

Originally, this case was intended for an E8600 on a 120.2, a 4870 X2 on a 120.2 with a Rampage Extreme with a chipset loop only on a 120.1.

More than enough cooling for that!

But the Rampage Extreme board drove me insane and so I sold everything and jumped on i7...but obviously the heat issues are such that I now don't have enough cooling.

Take your time. Find a lower end system for this case and then step up to a desktop case.

[RedRaider]

The EK SUPREME is kinda like Buddy Ryan's "46 Defense."

Pressure, it's all about Pressure...:D

That's the plan for the next little while.

Since this current system is still kicking ass as it is, I'm going to take my time and collect the parts for a more appropriate setup.

Get a Iwaki U Cunkistanii !
Mount Iwaki on yer forehead
shove yer head up yer butt
hook, tubing out yer ass ..
inlet down yer throat ..
No need for a RES .
stick yer ass in a bucket of ice water
( you have alot of the ice stuff there in Cunkastani )

Problem solved ..


See was that not EASY ??

Supreme RulZ the world

FTW with an Iwaki ...


lesson must be learned by ALL !

Must I repeat this over & over

Say thank You
BigSlappy !

I'm gonna start a " Ask BigSlappy Thread " to solve the worlds problems If I MUST !!

[Eridani]

you must, you must. :D:D

I taped a heatsink onto the bottom of a DDC during a leak test. It kept the pump much cooler, but added a slight ringing sound.
-and you know I'm not set up to figure out heat dump...
